[0002] As business develops, network scenarios that require long-distance data transmission have emerged. For example, a computing power hub for data calculation is deployed in location A, location B transmits data to the computing power hub in location A and uses the computing power hub in location A for data calculation, and location A feeds back the calculation results to location B.

[0164] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0165] The technical solutions of the embodiments of the present application can be applied to data communication systems for various data processing, such as wired data communication systems, or wireless data communication systems (such as long term evolution (LTE) systems, fifth generation (5G) communication systems), and other similar data communication systems. In addition, the data communication system can also be applied to future-oriented communication technologies, all of which are applicable to the technical solutions provided in the embodiments of the present application. The system architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Those skilled in the art will appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0166] See also Figure 1 , Figure 1 A schematic diagram of the structure of a data communication system provided in an embodiment of the present application. A data communication system provided in an embodiment of the present application includes: a transmitting end, a receiving end, a first communication device and a second communication device. It should be noted that the second communication device is any communication device between the first communication device and the receiving end.

[0167] Wherein, the first communication device and the second communication device can be a switch or a router, etc., which are switching devices used to forward service messages in a communication network. Wherein, the first communication device and the second communication device are hardware devices used to connect two or more communication networks, and act as gateways between communication networks, and can read the destination address (IP address and / or MAC address) in the service message and decide how to transmit the service message according to the destination address. The first communication device and the second communication device can understand different protocols, such as the Ethernet protocol used by a local area network, the transmission control protocol / internet protocol (TCP / IP) protocol used by the Internet, etc., so that the first communication device and the second communication device can analyze the destination addresses of service messages transmitted from various types of networks, and convert non-TCP / IP addresses into TCP / IP addresses, or vice versa. Then, each service message is transmitted to the destination address according to the optimal transmission path according to the selected routing algorithm, so the first communication device and the second communication device can connect the non-TCP / IP network to the Internet.

[0168] In some feasible implementations, the transmitting end / receiving end may be a terminal device. The terminal device may be a communication device with wireless communication function, such as a smart phone, a tablet computer, a desktop computer, an Internet of Things (IoT) device, etc. An IoT device may be a household appliance, a smart home, a transportation tool, a tool device, a service device, a service facility, or a wearable device, etc. IoT devices may include, but are not limited to, a smart refrigerator, a smart washing machine, a smart water meter, a smart electric meter, a smart car, a vehicle-mounted device, or a wearable device, etc.

[0169] In some possible implementations, the sending end / receiving end may be a computing device cluster. The computing device cluster includes at least one computing device. The computing device may be a server, such as a central server, an edge server, or a local server in a local data center. In some embodiments, the computing device may also be a terminal device such as a desktop computer, a laptop computer, or a smart phone.

[0170] In some possible implementations, the sending end / receiving end may be a server (such as a cloud server). The server may be a server cluster composed of multiple servers, or a cloud computing service center. Among them, a large number of basic resources owned by the cloud service provider are deployed in the cloud computing service center. For example, a large number of basic resources such as computing resources, storage resources, and network resources are deployed in the cloud computing service center. The cloud computing service center can use this large number of basic resources to implement the network operation and maintenance method provided in the embodiment of the present application, and to implement more services.

[0171] In some possible implementations, the sending end and / or the receiving end connects the first communication device and the second communication device through a network (local area network or wide area network). The sending end and / or the receiving end can also be directly connected to the first communication device and the second communication device, which is not limited here.

[0172] For example, the first communication device and the second communication device are switches, the sending end, the receiving end, and the first communication device and the second communication device are all in the same local area network, and the sending end and the receiving end are directly connected to the first communication device and the second communication device respectively. For another example, the first communication device and the second communication device are switches, the sending end and the first communication device and the second communication device are not in the same local area network, the sending end and the first communication device and the second communication device are connected through a public network, the receiving end and the first communication device and the second communication device are in the same local area network, and the receiving end and the first communication device and the second communication device are directly connected. For another example, the first communication device and the second communication device are routers, the sending end, the receiving end, and the first communication device and the second communication device are not in the same local area network, and the sending end and the receiving end are connected to the first communication device and the second communication device respectively through a public network.

[0173] In some possible implementations, the first communication device and the second communication device may be a data-center interconnect (DCI) gateway switch or a DCI router.

[0174] like Figure 1 As shown, the network path between the transmitting end and the receiving end through the first communication device and the second communication device is called the first network path. It can be understood that the first network path can also pass through other communication devices, and the embodiment of the present application does not limit this.

[0175] See also Figure 2 , Figure 2 Schematic diagram of a network status feedback mechanism based on redundant acknowledgment messages. Currently, a common network status feedback mechanism is a feedback mechanism based on redundant acknowledgment messages (ACK) at the receiving end. For example, when the network is congested, the cache of the communication device overflows and packet loss occurs. After receiving the message that arrives out of order, the receiving end sends a redundant ACK message to the sending end. When the receiving end receives multiple redundant ACK messages, for example, 3 redundant ACK messages, it is determined that the network is congested and packet loss occurs.

[0176] The applicant has found that there are many problems with the above-mentioned network status feedback mechanism. Based on the redundant ACK message feedback of packet loss, the sender only knows that the queue accumulation in the network has exceeded the communication device cache. On the one hand, when the queue accumulation does not exceed the communication device cache, the sender cannot perceive that the network is congested. On the other hand, even if the sender perceives the network congestion through redundant ACK messages, it cannot accurately know the actual available bandwidth resources in the network, and can only vaguely know that the sending bandwidth has exceeded the network bottleneck bandwidth. In the network scenario of long-distance data transmission, the sender needs to obtain the accurate network status between the sender and the receiver, and adjust the data transmission according to the network status to avoid data congestion and achieve high throughput and low latency for data transmission. Therefore, how the sender can accurately obtain the network status has become a problem to be solved.

[0177] Based on this, an embodiment of the present application proposes a method for measuring network status, wherein a first communication device receives first status information, and the first status information is network status information related to a first network path determined by a second communication device. Then, the first communication device sends the first status information to a transmitting end, so that the transmitting end obtains more accurate network status information, avoids data congestion, and achieves high throughput and low latency of data transmission.

[0178] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. Figure 3 , Figure 3A schematic diagram of an embodiment of a method for measuring a network state proposed in an embodiment of the present application. A method for measuring a network state proposed in an embodiment of the present application includes:

[0179] S1. The second communication device determines first status information.

[0180] In step S1, the second communication device determines first status information, and the first status information is network status information related to the first network path in the second communication device. The first network path is a network path between a sending end and a receiving end, and the first network path passes through the first communication device and the second communication device, and the second communication device is any communication device between the first communication device and the receiving end in the first network path. The network path can be identified by a set of address information, for example, the first network path is marked by the address information of the sending end and the address information of the receiving end.

[0181] Specifically, the first status information may include: status information of each port in the second communication device. For example, the first status information includes any one or more of the following: remaining bandwidth of the port of the second communication device, cache queue occupancy of the port of the second communication device, remaining cache of the port of the second communication device, number of data flows of the port of the second communication device, or number of packet losses of the port of the second communication device.

[0182] Furthermore, the first status information may also include other network status information. For example, the first status information includes any one or more of the following: the remaining bandwidth of the first network path, the number of data flows of the first network path, or the one-way delay from the first communication device to the second communication device, etc., wherein the remaining bandwidth of the first network path is the minimum remaining bandwidth of the port of any communication device in the first network path.

[0183] It is understandable that the first status information may also include other network status information related to the first network path, and this embodiment of the present application does not limit this.

[0184] The following describes how the second communication device determines the first state information. Exemplarily, the second communication device determines the first state information using any one or more of the following methods 1 to 4.

[0185] Method 1, please refer to Figure 4 , Figure 4 The method for determining the first status information by the second communication device includes:

[0186] G1. A first communication device sends a first detection message to a second communication device, where the first detection message is used to instruct the second communication device to determine first status information.

[0187] In step G1, optionally, the first detection message may also carry a sending timestamp of when the first communication device sends the first detection message.

[0188] Optionally, the first communication device may periodically send the first detection message to the second communication device. For example, the first communication device sends a first detection message to the second communication device every 5 seconds.

[0189] G2. The second communication device determines first status information according to the first detection message.

[0190] In step G2, in response to the first communication device sending the first detection message, the second communication device receives the first detection message. The second communication device obtains the port information of each port of the second communication device according to the first detection message, and the port information indicates the state of the port. The port information includes but is not limited to: the remaining bandwidth of the port, the occupancy of the cache queue of the port, the remaining cache of the port, the number of data flows of the port, and / or the number of packet losses of the port.

[0191] Optionally, when the first detection message carries a sending timestamp of the first communication device sending the first detection message, the second communication device records the receiving timestamp when receiving the first detection message. Then, the second communication device determines the unilateral delay between the first communication device and the second communication device on the first network path based on the sending timestamp and receiving timestamp carried by the message.

[0192] Exemplarily, the first state information is as shown in Table 1.

[0193] Table 1

[0194]

[0195] Optionally, the first status information may also include idle or lightly loaded port numbers. For example, when the second communication device measures the local network status in response to the first detection message, it finds that the traffic volume of some ports is lightly loaded or idle. These idle or lightly loaded port numbers are recorded in the first status information.

[0196] Method 2, please refer to Figure 5 , Figure 5 The method for determining the first status information by the second communication device includes:

[0197] R1. The third communication device sends a second detection message to the second communication device, where the second detection message is used to instruct the second communication device to determine first status information. The second detection message carries second status information, which is status information related to the first network path determined by the third communication device.

[0198] In step R1, on the first network path, when there are other communication devices between the first communication device and the second communication device, for example, there is a third communication device between the first communication device and the second communication device. Then the third communication device will also receive the first detection message, and the third communication device determines the network status information related to the first network path in the third communication device according to the indication of the first detection message. For the convenience of description, this network status information is referred to as the second status information. The specific method for the third communication device to determine the second status information is similar to the method for the second communication device to determine the first status information, and will not be repeated here. Then, the third communication device records the second status information in the first detection message to obtain a second detection message, and the second detection message is a detection message with the second status information added. The third communication device forwards the second detection message to the next hop node.

[0199] The second status information is similar to the first status information and will not be described in detail here.

[0200] R2. The second communication device obtains third status information according to the first detection message, where the third status information is status information related to the first network path collected locally by the second communication device.

[0201] In step R2, the next hop node of the third communication device is taken as an example. After the second communication device receives the first detection message, the second communication device obtains the local network status information related to the first network path. For the convenience of description, the local network status information related to the first network path collected (or obtained) by the second communication device is called the third status information. The third status information is similar to the first status information and will not be described here.

[0202] Optionally, the third state information is carried in the payload of the first detection message.

[0203] R3. The second communication device determines the first state information according to the second state information and the third state information.

[0204] In step R3, the second communication device obtains the third state information from the first detection message, and the second communication device obtains the second state information in response to the first detection message. Then, the second communication device determines the first state information according to the third state information and the second state information recorded in the first detection message.

[0205] Specifically, in the process of determining the first state information by the second communication device, it is necessary to determine the network state information related to the network path in the first state information in combination with the network state information carried by the first detection message. Take the network state information as the remaining bandwidth of the first network path as an example. In one example, the remaining bandwidth of the first network path in the third state information is 5 gigabits per second (Gbps), and the remaining bandwidth of the first network path in the second state information is 6Gbps. Since the remaining bandwidth of the first network path determined locally by the second communication device is greater than the remaining bandwidth of the first network path in the first detection message, the first state information is based on the remaining bandwidth of the first network path carried by the first detection message, that is, the remaining bandwidth of the first network path included in the first state information is 5Gbps.

[0206] In another example, the remaining bandwidth of the first network path in the third state information is 7 Gbps, and the remaining bandwidth of the first network path in the second state information is 6 Gbps. Since the remaining bandwidth of the first network path determined locally by the second communication device is less than the remaining bandwidth of the first network path in the first detection message, it is necessary to update the remaining bandwidth of the first network path carried by the first detection message (third state information) according to the remaining bandwidth of the first network path determined locally by the second communication device (second state information), and the remaining bandwidth of the first network path included in the first state information is 6 Gbps. Then, the second communication device updates the network state information carried by the first detection message, and the remaining bandwidth of the first network path in the network state information carried by the first detection message after the update is 6 Gbps.

[0207] Method 3, please refer to Figure 6 , Figure 6 The method for determining the first status information by the second communication device includes:

[0208] H1. The second communication device receives a third message, the source address of the third message points to the receiving end, and the destination address of the third message points to the sending end.

[0209] In step H1, the second communication device receives a third message, the source address of the third message points to the receiving end, the destination address of the third message points to the sending end, and the transmission path of the third message is the first network path. If the message sent from the sending end to the receiving end is called a forward message, then the third message is a reverse message sent from the receiving end to the sending end.

[0210] It should be noted that the third message can be a data message, or a response message, such as an ACK message, or other messages, and the embodiments of the present application do not limit this.

[0211] H2. The second communication device determines the first status information according to the third message.

[0212] In step H2, after the second communication device receives the third message, the second communication device determines the first state information according to an instruction of the third message.

[0213] Optionally, the third message carries a first indicator bit, and the first indicator bit is used to enable the communication device to measure the network status. For example, the first indicator bit is "1". After receiving the third message, the second communication device detects the first indicator bit of the third message. When the first indicator bit is "1", the second communication device enables the measurement of the network status. The second communication device determines the first status information according to the indication of the third message.

[0214] Further optionally, the first indicator bit is used to enable the type of network status measured by the communication device. For example, the first indicator bit indicates that the communication device is enabled to measure the unilateral delay, and the second communication device measures the unilateral delay from the first communication device to the second communication device according to the third message. For another example, the first indicator bit indicates that the communication device is enabled to measure the remaining bandwidth of the port, and the second communication device measures the remaining bandwidth of the port in the second communication device according to the third message. Exemplarily, the first indicator bit is "100", and the first indicator bit indicates that the communication device is enabled to measure the unilateral delay. In another example, the first indicator bit is "010", and the first indicator bit indicates that the communication device is enabled to measure the remaining bandwidth of the port. In another example, the first indicator bit is "110", and the first indicator bit indicates that the communication device is enabled to measure the unilateral delay and the remaining bandwidth of the port.

[0215] Method 4, please refer to Figure 7 , Figure 7 The method for determining the first status information by the second communication device includes:

[0216] Y1. The second communication device receives a third message from a fourth communication device, where the third message carries fourth status information, and the fourth status information is status information related to the first network path determined by the fourth communication device.

[0217] In step Y1, on the first network path, when there are other communication devices between the receiving end and the second communication device, for example, there is a fourth communication device between the receiving end and the second communication device. Then the fourth communication device will also receive the third message, and the fourth communication device determines the network status information related to the first network path in the fourth communication device according to the instructions of the third message. For the convenience of description, this network status information is referred to as the fourth status information. The specific method for the fourth communication device to determine the fourth status information is similar to the method for the second communication device to determine the first status information, and will not be repeated here. Then, the fourth communication device records the fourth status information in the third message, and the fourth communication device forwards the third message with the fourth status information added to the next hop node.

[0218] The fourth state information is similar to the first state information and will not be elaborated here.

[0219] The fourth state information may be carried in a message header of the third message. For example, the fourth state information is carried in a reserved field of the message header of the third message.

[0220] Optionally, the message (e.g., the first message, the second message, or the third message) in the embodiment of the present application may also include a second indicator bit, and the second indicator bit is used to indicate the type of network status information carried by the third message. For example, the second indicator bit indicates that the fourth status information is: the number of packet losses of the port of the fourth communication device. For another example, the second indicator bit indicates that the fourth status information is: the remaining bandwidth of the first network path.

[0221] For easier understanding, see Fig.14 , Fig.14 A structural schematic diagram of a message in an embodiment of the present application. The message header of the message (e.g., the first message, the second message, or the third message) includes: a first indicator bit, a second indicator bit, and a status value of the network status information, wherein the first indicator bit is an enable bit for measuring the network status, and the first indicator bit indicates that the communication device measures the network status to determine the network status information; the second indicator bit, the second indicator bit indicates the type of network status information carried by the message; the status value of the network status information and the second indicator bit together constitute the network status information, for example, the second indicator bit indicates that the type of the network status information is the remaining bandwidth of the port, and the status value of the network status information is 5Gbps, then the network status information is: the remaining bandwidth of the port is 5Gbps.

[0222] Y2. The second communication device obtains third status information, where the third status information is network status information related to the first network path collected locally by the second communication device.

[0223] In step Y2, the next hop node of the fourth communication device is the second communication device as an example. After the second communication device receives the third message, the second communication device obtains the local network status information related to the first network path. For the sake of convenience, the local network status information related to the first network path collected (or obtained) by the second communication device is called the third status information. The third status information is similar to the first status information and will not be described here.

[0224] Optionally, the third state information is carried in the effective payload of the third message.

[0225] Y3. The second communication device determines the first state information based on the third state information and the fourth state information.

[0226] In step Y3, the second communication device obtains the fourth state information from the third message, and the second communication device obtains the fourth state information in response to the third message. Then, the second communication device determines the first state information according to the fourth state information and the fourth state information recorded in the third message.

[0227] Specifically, in the process of determining the first state information by the second communication device, it is necessary to determine the network state information related to the network path in the first state information in combination with the network state information carried by the third message. Take the network state information as the remaining bandwidth of the first network path as an example. In one example, the remaining bandwidth of the first network path in the fourth state information is 5Gbps, and the remaining bandwidth of the first network path in the third state information is 6Gbps. Since the remaining bandwidth of the first network path determined locally by the second communication device is greater than the remaining bandwidth of the first network path in the third message, the first state information is based on the remaining bandwidth of the first network path carried by the third message, that is, the remaining bandwidth of the first network path included in the first state information is 5Gbps.

[0228] In another example, the remaining bandwidth of the first network path in the fourth state information is 7Gbps, and the remaining bandwidth of the first network path in the third state information is 6Gbps. Since the remaining bandwidth of the first network path determined locally by the second communication device is less than the remaining bandwidth of the first network path in the third message, it is necessary to update the remaining bandwidth of the first network path carried by the third message (fourth state information) according to the remaining bandwidth of the first network path determined locally by the second communication device (third state information), and the remaining bandwidth of the first network path included in the first state information is 6Gbps. Then, the second communication device updates the network state information carried by the third message, and the remaining bandwidth of the first network path in the network state information carried by the third message after the update is 6Gbps.

[0229] In the above manner, after the second communication device determines the first state information, the second communication device can associate the first state information with the first network path and save it locally. Since the first network path can be represented by a set of source addresses and destination addresses (such as the address information of the sender and the address information of the receiver), the second communication device locally saves the first state information and the first network path, which can be shown in Table 2.

[0230] Table 2

[0231]

[0232] S2. The second communication device sends first status information to the first communication device, where the first status information is network status information related to the first network path in the second communication device.

[0233] In step S2, after the second communication device determines the first status information, the second communication device sends the first status information to the first communication device. The following describes how the second communication device sends the first status information to the first communication device. Exemplarily, the second communication device sends the first status information to the first communication device using any one or more of the following methods 1 to 2.

[0234] Method 1, please refer to Figure 8 , Figure 8 The method for sending first status information by a second communication device to a first communication device includes:

[0235] J1. The second communication device generates a second feedback message, where the second feedback message carries the first status information.

[0236] In step J1, after the second communication device generates the first state information, the second communication device may generate a second feedback message, where the second feedback message carries the first state information, for example, the first state information is carried in the payload of the second feedback message.

[0237] In a possible implementation, after the second communication device receives the first detection message, the second communication device determines the first state information according to the first detection message and generates a second feedback message. After the second communication device determines the first state information, the second communication device fills the first state information into the second feedback message and sends the second feedback message to the first communication device.

[0238] In another possible implementation, after the second communication device receives the third message, the second communication device determines the first state information according to the third message and generates a second feedback message. After the second communication device determines the first state information, the second communication device fills the first state information into the second feedback message and sends the second feedback message to the first communication device.

[0239] In another possible implementation, the second communication device periodically generates a second feedback message and sends the second feedback message to the first communication device. For example, at time T1, the second communication device determines the first state information #1, the second communication device generates the second state message #1, the second state message #1 carries the first state information #1, and the second communication device sends the second state message #1 to the first communication device; at time T2, the second communication device determines the first state information #2, the second communication device generates the second state message #2, the second state message #2 carries the first state information #2, and the second communication device sends the second state message #2 to the first communication device; at time T3, the second communication device determines the first state information #3, the second communication device generates the second state message #3, the second state message #3 carries the first state information #3, and the second communication device sends the second state message #3 to the first communication device.

[0240] Optionally, the second feedback message may also be a data message (or ACK message or other message) whose source address is the receiving end and whose destination address is the sending end. That is, the second communication device receives the data message (or ACK message or other message) from the receiving end, and then the second communication device uses the data message (or ACK message or other message) as the second feedback message. The second communication device fills the first state information in the second feedback message.

[0241] J2. The second communication device sends a second feedback message to the first communication device.

[0242] Method 2, please refer to Fig. 9 , Fig. 9 The method for sending first status information by a second communication device to a first communication device includes:

[0243] K1. The second communication device receives a third message, the source address of the third message points to the receiving end, and the destination address of the third message points to the sending end.

[0244] In step K1, in a possible implementation, after receiving the third message, the second communication device generates first state information according to the third message, and then proceeds to step K2.

[0245] In another possible implementation, the second communication device has generated the first status information. When the second communication device receives the third message, the second communication device determines an address tuple based on the source address of the third message (the address information of the receiving end) and the destination address of the third message (the address information of the sending end). The address tuple includes the source address of the third message and the destination address of the third message. For ease of description, the address tuple related to the third message is referred to as the target address tuple. Then, the second communication device determines the first status information from one or more sets of network status information stored locally based on the target address tuple. For example, the address information of the receiving end is IP2, the address information of the sending end is IP1, and the target address tuple is<IP1,IP2> The second communication device locally stores multiple sets of network status information:<IP1,IP2> : Network status information #1","<IP3,IP2> : Network status information #2" and "<IP1,IP4> : Network status information #3". The second communication device determines the first status information as network status information #1 from multiple sets of network status information stored locally according to the target address tuple.

[0246] K2. The second communication device fills the first status information into the third message.

[0247] In step K2, after determining the first state information, the second communication device fills the first state information into the third message. Specifically, the second communication device fills the first state information into a reserved field of the third message. The reserved field may be in the message header of the third message.

[0248] K3. The second communication device sends a third message to the first communication device, where the third message carries the first status information.

[0249] In step K3, after the second communication device fills the first state information into the third message, the third message filled with the first state information is forwarded to the first communication device along the first network path.

[0250] S3. The first communication device sends first status information to the transmitting end.

[0251] In step S3, after the first communication device receives the first status information from the second communication device, the first communication device sends the first status information to the sending end.

[0252] Optionally, after the first communication device receives the first state information from the second communication device, the first communication device saves the first state information locally. Optionally, the first state information associates the identification information of the first network path with the first state information and saves it locally. The identification information of the first network path can be an address tuple consisting of the address information of the sending end and the address information of the receiving end.

[0253] The following describes how the first communication device sends the first state information to the sending end. Exemplarily, the first communication device sends the first state information to the sending end in any one or more of the following ways 1 to 2.

[0254] Method 1, please refer to Fig.10 , Fig.10 The method for sending first status information by a first communication device to a transmitting end includes:

[0255] D1. A transmitting end sends a first message to a first communication device, wherein a source address of the first message points to the transmitting end, and a destination address of the first message points to the receiving end.

[0256] In step D1, the sender sends a first message to the receiver via a first network path, the source address of the first message points to the sender, and the destination address of the first message points to the receiver. Accordingly, the first communication device in the first network path receives the first message.

[0257] It should be noted that the first message can be a data message, or a response message, such as an ACK message, or other messages, and the embodiments of the present application do not limit this.

[0258] D2. The first communication device determines first status information according to a source address of the first message and a destination address of the first message.

[0259] In step D2, the first communication device determines a target address tuple according to the source address of the first message and the destination address of the first message, and the destination address tuple includes the source address of the first message and the destination address of the first message. Then, the first communication device determines the first status information from one or more groups of network status information saved by the first communication device according to the target address tuple, wherein each group of the network status information is associated with a group of address tuples, and the address tuples include the source address and the destination address of a network path, and the address tuple corresponding to the first status information is the same as the target address tuple.

[0260] In one possible implementation, the first bit of the address tuple corresponding to the first status information includes the address of the sending end, the second bit of the address tuple corresponding to the first status information includes the address of the receiving end, and the address tuple corresponding to the first status information indicates the first network path.

[0261] For example, the source address of the first message is "IP1", and the destination address of the first message is "dIP2". The destination address tuple determined according to the first message is "<IP1,IP2> ". The first communication device determines the first status information from one or more groups of network status information locally stored by the first communication device. Taking Table 2 as an example, the one or more groups of network status information locally stored by the first communication device, the first status information determined by the first communication device from the one or more groups of network status information illustrated in Table 2 according to the target address tuple is status information #1.

[0262] D3. The first communication device generates a first feedback message, and the first communication device sends the first feedback message to the transmitting end, where the first feedback message carries first status information.

[0263] In step D3, the first communication device generates a first feedback message according to the received first message. The first feedback message carries the first state information. Then the first communication device sends the first feedback message to the sending end, notifying the sending end of the first state information through the first feedback message.

[0264] Method 2, please refer to Fig.11 , Fig.11 The method for sending first status information by a first communication device to a transmitting end includes:

[0265] F1. The first communication device receives a second message, the source address of the second message points to the receiving end, and the destination address of the second message points to the sending end.

[0266] In step F1, the receiving end sends a second message to the sending end through the first network path, and the corresponding first communication device receives the second message. The source address of the second message points to the receiving end, and the destination address of the second message points to the sending end.

[0267] Regarding the second message, optionally, the second message carries a first indicator bit, and the first indicator bit is used to enable the communication device to measure the network status. For example, the first indicator bit is "1". After receiving the second message, the second communication device detects the first indicator bit of the second message. When the first indicator bit is "1", the second communication device enables the measurement of the network status. The second communication device determines the first status information according to the indication of the second message. The first communication device determines that the second message can carry the network status information according to the first indicator bit of the second message, and thus enters step F2.

[0268] Further optionally, the first indicator bit is used to enable the type of network status measured by the communication device. For example, the first indicator bit indicates that the communication device is enabled to measure the unilateral delay, and the second communication device measures the unilateral delay from the first communication device to the second communication device according to the second message. For another example, the first indicator bit indicates that the communication device is enabled to measure the remaining bandwidth of the port, and the second communication device measures the remaining bandwidth of the port in the second communication device according to the second message. Exemplarily, the first indicator bit is "100", and the first indicator bit indicates that the communication device is enabled to measure the unilateral delay. In another example, the first indicator bit is "010", and the first indicator bit indicates that the communication device is enabled to measure the remaining bandwidth of the port. In another example, the first indicator bit is "110", and the first indicator bit indicates that the communication device is enabled to measure the unilateral delay and the remaining bandwidth of the port. The first communication device determines the type of network status information that the second message can carry according to the first indicator bit of the second message, and enters step F2.

[0269] It should be noted that the second message can be a data message, or a response message, such as an ACK message, or other messages, and the embodiments of the present application do not limit this.

[0270] F2. The first communication device determines first status information according to the source address of the second message and the destination address of the second message.

[0271] In step F2, the first communication device determines a target address tuple according to the source address of the second message and the destination address of the second message, wherein the target address tuple includes the source address of the second message and the destination address of the second message. Then, the first communication device determines the first state information from one or more groups of network state information stored by the first communication device according to the target address tuple, wherein each group of the state information is associated with an address tuple, wherein the address tuple includes the source address and the destination address of a network path, and the address tuple corresponding to the first state information is the same as the target address tuple.

[0272] In one possible implementation, the first bit of the address tuple corresponding to the first status information includes the address of the sending end, the second bit of the address tuple corresponding to the first status information includes the address of the receiving end, and the address tuple corresponding to the first status information indicates the first network path.

[0273] For example, the source address of the second message is "IP2", and the destination address of the second message is "IP1". By exchanging the source address and the destination address of the second message, the destination address tuple determined is "<IP1,IP2> ". The first communication device determines the first status information from one or more groups of network status information locally stored by the first communication device. Taking Table 2 as an example, the one or more groups of network status information locally stored by the first communication device, the first status information determined by the first communication device from the one or more groups of network status information illustrated in Table 2 according to the target address tuple is status information #1.

[0274] F3. The first communication device fills the first status information into the second message, and the first communication device sends the second message to the sending end, where the second message carries the first status information.

[0275] In step F3, after the first communication device determines the first state information, it fills the first state information into the second message. Specifically, the first communication device fills the first state information into a reserved field of the second message. The reserved field may be in a message header of the second message. After the first communication device fills the first state information into the second message, it forwards the second message filled with the first state information along the first network path to the sending end.

[0276] It should be noted that the process of measuring network status information from the receiving end to the sending end is similar to the above-mentioned process of measuring network status information from the sending end to the receiving end, and will not be described in detail here.

[0277] In an embodiment of the present application, a first communication device receives first status information, and the first status information is network status information related to a first network path determined by a second communication device. Then, the first communication device sends the first status information to a transmitting end. This enables the transmitting end to obtain more accurate network status information, avoid data congestion, and achieve high throughput and low latency in data transmission. Through the above method, rapid feedback of network status information is achieved, and the feedback delay of network status information is reduced to the microsecond level. In ultra-long distance data transmission scenarios, congestion control, flow control and / or load balancing based on network status information are implemented, thereby improving data transmission efficiency and achieving high throughput and low latency in ultra-long distance data transmission scenarios.
