[0080] Embodiment one

[0081] See Figure 1 , Figure 1 is a flow chart of an information processing method based on in-stream detection provided by an embodiment of the present application. The information processing method based on in-stream detection is applied to a first heterogeneous network side, and specifically comprises:

[0082] S11: establishing a first mapping table for a target packet stream; wherein the first mapping table comprises a one-to-one correspondence relationship between a flow label of the target packet stream and a first in-stream detection identifier thereof;

[0083] S12: sending the target packet stream carrying the flow label to a second heterogeneous network side, so that the second heterogeneous network side establishes a second mapping table for a received target packet; wherein the second mapping table comprises a one-to-one correspondence relationship between a flow label of the target packet stream and a second in-stream detection identifier thereof;

[0084] S13: sending the first mapping table to a super controller through a network management system, so that the super controller performs one-to-one correspondence between in-stream detection data of the first heterogeneous network side and in-stream detection data of the second heterogeneous network side according to the first mapping table and the second mapping table reported by the second heterogeneous network side.

[0085] Wherein, the target packet stream is a packet stream that needs to be subjected to in-stream detection, which is determined by screening the service packets (such as cloud private line service packets) entering the first heterogeneous network. In the first heterogeneous network side, the target packet stream carries the first in-stream detection identifier and the flow label.

[0086] It should be understood that the first heterogeneous network side and the second heterogeneous network are two different types of networks, and the first heterogeneous network can be a SPN network, a router network, or the like; similarly, the second heterogeneous network can also be a SPN network, a router network, or the like. In the present embodiment, the SPN network can implement the information processing method based on in-stream detection described in Embodiment I or Embodiment II, and similarly, the router network can also implement the information processing method based on in-stream detection described in Embodiment I or Embodiment II.

[0087] The flow label is an IPv6 flow label created based on the IPv6 protocol (Internet Protocol Version 6, referred to as the next-generation Internet protocol).

[0088] In the present embodiment, by establishing a first mapping table for the target message flow on the first heterogeneous network side and reporting to the super controller, and establishing a second mapping table for the target message on the second heterogeneous network side and reporting to the super controller, the super controller can correspond the in-stream detection data of the first heterogeneous network side and the in-stream detection data of the second heterogeneous network side according to the first mapping table reported by the first heterogeneous network side and the second mapping table reported by the second heterogeneous network side, thereby realizing end-to-end pull-through of the in-stream detection function. In this way, the end-to-end information processing based on in-stream detection can be realized without greatly changing the existing network equipment and protocols, and the consistency and availability of the information processing function based on in-stream detection between heterogeneous networks can be ensured.

[0089] Specifically, the first mapping table established for the target message flow includes:

[0090] The first node of the first heterogeneous network side generates a first in-stream detection identifier and a flow label for the target message flow that needs to be subjected to in-stream detection; wherein the flow label is used to mark the corresponding target message flow in the second heterogeneous network side.

[0091] The first node of the first heterogeneous network side establishes a first mapping table corresponding to the first node of the first heterogeneous network according to the first in-stream detection identifier and the flow label of the target message flow.

[0092] Further, after the first node of the first heterogeneous network side establishes a first mapping table corresponding to the first node of the first heterogeneous network according to the first in-stream detection identifier and the flow label of the target message flow, the method further includes:

[0093] The first node of the first heterogeneous network side adds a first flow detection message header to the target message flow, and forwards the target message flow with the added first flow detection message header to a next node to transmit to an exit node of the first heterogeneous network side along a path of the first heterogeneous network side; wherein the first flow detection message header comprises the first flow detection identifier, the flow label, a detection type, and a detection period.

[0094] Further, the first node of the first heterogeneous network side reports a first mapping table corresponding to the first node of the first heterogeneous network established by the first node to the super controller.

[0095] In the embodiment of the application, taking the SPN network as the first heterogeneous network, the first node in the SPN network is referred to as a first node, the last node (i.e., the node connected to the router network) is referred to as an exit node, and the nodes between the first node and the exit node are referred to as intermediate nodes. It should be understood that the first node and the exit node can be devices for connecting terminals to the network. The first flow detection identifier of the service message, the flow label, and the first mapping table between the first flow detection identifier and the flow label are generated by the first node of the first heterogeneous network side, and then are forwarded to the next node by the first node. Specifically, the first node of the SPN network side performs the following steps:

[0096] According to the matching rule configured by the user, the service message entering the SPN network is screened, and a target message flow requiring flow detection is screened out. It should be noted that the matching rule for screening the private line service message requiring flow detection is not specifically limited in the embodiment of the application, and the user can configure it according to actual needs.

[0097] A unique first flow detection identifier is generated for each target message flow; the first flow detection identifier is used to mark the corresponding target message flow in the SPN network;

[0098] A unique flow label is generated for each target message flow based on the IPv6 protocol; the flow label is used to mark the corresponding target message flow in the router network;

[0099] Then, a first mapping table of the first flow detection identifier and the flow label is established, and the values of the first flow detection identifier and the flow label are one-to-one corresponding;

[0100] A first flow detection message header is added to the message header of the target message flow; the first flow detection message header comprises the first flow detection identifier, the measurement type, the measurement period, the flow label, and other information, and is used to guide the downstream device (i.e., the intermediate node of the SPN network) to collect, analyze, and feedback the flow detection data;

[0101] The target packet stream added with the first in-stream detection packet header is forwarded to the next node of the SPN network, and is transmitted along the path of the SPN network to the egress node of the SPN network.

[0102] Specifically, the method further comprises:

[0103] The first node of the first heterogeneous network side forwards the target packet stream added with the first in-stream detection packet header to the next node of the first heterogeneous network side;

[0104] The next node of the first heterogeneous network side identifies the target packet stream according to the first in-stream detection packet header of the received target packet stream;

[0105] The next node of the first heterogeneous network side collects and analyzes in-stream detection data of the target packet stream according to the measurement type and the measurement period in the first in-stream detection packet header, and reports the collected in-stream detection data to the super controller;

[0106] The next node of the first heterogeneous network side forwards the target packet stream to the next node thereof, so as to be transmitted along the path of the first heterogeneous network side to the egress node thereof.

[0107] For example, also taking the SPN network as the first heterogeneous network, the intermediate node of the SPN network side performs the following steps after receiving the target packet stream:

[0108] It is judged whether the packet header of the received target packet stream contains the first in-stream detection packet header, and the target packet stream needing in-stream detection is automatically identified. Specifically, when the packet header contains the first in-stream detection packet header, it is determined that the target packet stream is the target packet stream needing in-stream detection, otherwise it is determined that the target packet stream does not need in-stream detection;

[0109] For the target packet stream identified as needing in-stream detection, it is determined whether in-stream detection data of the target packet stream needs to be collected according to the measurement type in the first in-stream detection packet header. The in-stream detection data includes but is not limited to packet loss number, time delay, time delay jitter, etc.

[0110] The collected in-stream detection data is periodically reported to the super controller for analysis and presentation of in-stream detection data according to the measurement period in the first in-stream detection packet header through the Telemetry protocol;

[0111] Then the target packet stream is forwarded to the next node until the egress node is reached.

[0112] Specifically, the method further comprises:

[0113] The first isomeric network side export node stores the first isomeric network side export node corresponding first mapping table according to the first isomeric network side export node corresponding first mapping table.

[0114] The first isomeric network side export node stores the first isomeric network side export node corresponding first mapping table according to the first isomeric network side export node corresponding first mapping table.

[0115] Further, the first isomeric network side export node reports the first isomeric network side export node corresponding first mapping table established by the first isomeric network side export node to the super controller.

[0116] Exemplarily, when the target message flow reaches the first isomeric network side export node, the first isomeric network side export node stores the first isomeric network side export node corresponding first mapping table according to the first isomeric network side export node corresponding first mapping table, and then forwards to the second isomeric network side. Taking the SPN network as an example, the export node performs the following steps:

[0117] It is understood that the automatic identification process of the target message flow in the export node is the same as that in the intermediate node, and will not be repeated here.

[0118] For the target message flow identified as needing to perform flow detection, the first isomeric network side export node extracts the first isomeric network side export node corresponding first mapping table from the first isomeric network side export node corresponding first mapping table, and stores them together in the local, and establishes the corresponding first mapping table.

[0119] The target message flow is forwarded to the second isomeric network side (for example, a router network). It should be understood that since the UNI (user network interface) interface is used to connect between the isomeric networks, only the flow label generated based on the IPv6 protocol can enter the router network.

[0120] In the embodiment of the application, the first isomeric network side export node corresponding first mapping table containing the corresponding relationship between the first isomeric network side export node corresponding first mapping table and the flow label is reported to the super controller by the first node and the export node of the SPN network through Telemetry (Telemetry is a new generation of network monitoring technology for remote high-speed acquisition of data). The flow detection data is reported to the super controller by the intermediate node of each SPN network through Telemetry.

[0121] Similarly, the first node in the second heterogeneous network is referred to as a head node, the last node is referred to as an exit node, and the nodes between the head node and the exit node are referred to as intermediate nodes. It should be understood that the nodes can also be referred to as network devices or base stations, which are used as devices for accessing terminals to the network. The following steps are performed after the second heterogeneous network side receives the target message flow sent by the first heterogeneous network side.

[0122] Specifically, the head node of the second heterogeneous network side performs the following steps:

[0123] The entry node of the second heterogeneous network side, i.e., the head node in the second heterogeneous network side, generates a second flow detection identifier of the second heterogeneous network side, and establishes a mapping table of the identifier and an IPv6 flow label, and then forwards service data to a next hop and finally reaches a destination node. Specifically, the head node of the second heterogeneous network side performs the following operations:

[0124] It is judged whether the second flow detection message header of the received target message flow contains a flow label, and it is automatically identified that the target message flow needs to be subjected to flow detection; it should be understood that the automatic identification process of the target message flow in each node of the second heterogeneous network side is the same as that in each node of the first heterogeneous network side, and will not be described here.

[0125] A unique second flow detection identifier is generated for each target message flow, and the second flow detection identifier is used to mark the corresponding target message flow in the second heterogeneous network side;

[0126] A second mapping table of the second flow detection identifier and the flow label is established, and the second flow detection identifier and the value of the flow label are one-to-one corresponding;

[0127] A second flow detection message header is added to the message header of the target message flow, which contains the second flow detection identifier, the measurement type, the measurement period, the flow label and other information, and is used to guide the downstream device (i.e., the intermediate node of the second heterogeneous network side) to collect, analyze and feedback the flow detection data;

[0128] The target message flow with the added second flow detection message header is forwarded to the next node and transmitted to the exit node along the path of the second heterogeneous network side.

[0129] The intermediate node of the second heterogeneous network side performs the following steps after receiving the target message flow:

[0130] It is judged whether the message header of the received target message flow contains a second flow detection message header, and it is automatically identified that the target message flow needs to be subjected to flow detection; specifically, when the message header contains the second flow detection message header, it is determined that the target message flow is a target message flow that needs to be subjected to flow detection, otherwise it is determined that the target message flow does not need to be subjected to flow detection;

[0131] For the target packet flow identified as requiring in-stream detection, it is determined whether the in-stream detection data of the target packet flow needs to be collected according to the measurement type in the second in-stream detection packet header; wherein the in-stream detection data includes but is not limited to the number of packet loss, delay, delay jitter, etc.

[0132] According to the measurement period in the second in-stream detection packet header, the collected in-stream detection data is periodically reported to the super controller through the Telemetry protocol for analysis and presentation of in-stream detection data;

[0133] Then the target packet flow is forwarded to the next node until the egress node is reached.

[0134] When the target packet flow reaches the egress node of the second heterogeneous network side, the egress node of the second heterogeneous network side stores the second in-stream detection identifier and the flow label of the target packet flow, and locally establishes a corresponding second mapping table, and then forwards it to the super controller. Specifically, the egress node of the second heterogeneous network side performs the following steps:

[0135] It is determined whether the packet header of the received target packet flow contains a second in-stream detection packet header, and the target packet flow requiring in-stream detection is automatically identified; it should be understood that the automatic identification process of the target packet flow in the egress node is the same as that in the intermediate node, and will not be repeated here.

[0136] For the target packet flow identified as requiring in-stream detection, the second in-stream detection identifier and the flow label are extracted from the second in-stream detection packet header and stored together locally to establish a corresponding second mapping table;

[0137] Similarly, the second mapping table containing the correspondence between the second in-stream detection identifier and the flow label will be reported to the super controller by the first node and the egress node of the second heterogeneous network side through Telemetry (Telemetry is a new generation of network monitoring technology for remote high-speed data acquisition). In-stream detection data will be reported to the super controller by each intermediate node of the second heterogeneous network side through Telemetry.

[0138] When the service needs to be carried across domains, the network management systems of the first and second heterogeneous network sides will cooperate with the super controller SC to restore the topology of the target packet flow corresponding to the cloud private line service, and calculate the nodes and links causing packet loss and delay according to the in-stream detection data reported by the SPN network and each intermediate node of the second heterogeneous network side, and accurately present various network faults and network parameters to the user.

[0139] Specifically, the super controller SC performs the following steps:

[0140] Obtaining, from the network management system, a correspondence relationship between a first flow detection identifier and a flow label reported by a first node and an exit node on a first heterogeneous network side and a second heterogeneous network side, and a correspondence relationship between a second flow detection identifier and a flow label (i.e., a first mapping table and a second mapping table), and flow detection data reported by an intermediate node on the first heterogeneous network side and the second heterogeneous network side;

[0141] According to the correspondence relationship between the first flow detection identifier and the flow label and the correspondence relationship between the second flow detection identifier and the flow label, the flow detection data of the first heterogeneous network side and the flow detection data of the second heterogeneous network side are one-to-one corresponding, so as to realize end-to-end pull-through of the flow detection function; then the network management system performs the following index performance calculation and path restoration process. The following steps are performed by the network management system:

[0142] According to the data mapping relationship issued by the super controller SC and the flow detection data reported by the second heterogeneous network side, and the flow detection data reported by the first heterogeneous network side, the end-to-end packet loss rate, delay, delay jitter and other performance indicators of the target packet flow, and the packet loss number, delay and other performance parameters of each intermediate node in the first heterogeneous network side and the second heterogeneous network side are calculated; wherein the data mapping relationship includes a one-to-one correspondence relationship between the flow detection data of the first heterogeneous network side and the flow detection data of the second heterogeneous network side;

[0143] According to the data mapping relationship issued by the super controller SC, the flow detection data reported by the second heterogeneous network side, and the flow detection data reported by the first heterogeneous network side, the actual path of the target packet flow in the first heterogeneous network side and the second heterogeneous network side, and the nodes and links causing packet loss and delay are restored.

[0144] The flow detection data analysis result and the path restoration result are displayed to the user through a visual interface, helping the user to quickly locate and eliminate network faults, and improving business performance and quality.

[0145] Compared with the prior art, the embodiment of the application utilizes the flow label in the IPv6 protocol to respectively establish a first mapping table of the flow label and the first flow detection identifier in a first heterogeneous network (for example, an SPN network), and a first mapping table of the flow label and the second flow detection identifier in edge nodes (namely, the head node and the exit node) of a second heterogeneous network (for example, a router network), so that the flow detection data between the two heterogeneous networks are one-to-one corresponding through the first mapping table and the second mapping table, the consistency and availability of the end-to-end flow detection function of the heterogeneous network are ensured, the loss or change of the identifier is avoided, and the end-to-end flow detection function is realized. Meanwhile, the embodiment of the application does not need to greatly change the existing network equipment and protocol, and can realize the end-to-end flow detection function and tracking of the heterogeneous network based on the IPv6 flow label. The related information is discarded, the effective detection and tracking in the router network cannot be realized, and the efficiency and effect of the performance monitoring and optimization of the cross-domain service can be improved.

[0146] In addition, the embodiment of the application realizes the feature marking of the message flow corresponding to the real cloud private line service of the network by deploying the device supporting the flow detection in the two heterogeneous networks, so as to directly detect the performance indicators such as the time delay, the packet loss and the jitter of the network.
