[0046] Figure 1 Schematic diagram of the implementation process of the path monitoring method provided in the embodiments of this application Figure 1 ,like Figure 1 As shown, this embodiment provides a path monitoring method applied to a centralized management and control platform. The method includes the following steps:

[0047] Step 101: Receive first information reported by at least two nodes; wherein, the first information includes: node information and statistical information of the first colored message; the node port information represents the path to which the node port belongs; the statistical information of the first colored message includes: the number of the first colored message; the first colored message is a message used for packet loss measurement.

[0048] The path monitoring method provided in this application embodiment can be applied to the Global Scheduled Ethernet (GSE) network scenario, and the centralized management and control platform is used to realize the operation and maintenance management of the network.

[0049] In this embodiment, a path includes a head node, intermediate nodes, and a tail node. Each node includes an ingress port and an egress port. A node may have one or more ingress ports and one or more egress ports. A complete path includes the ingress and egress ports of the head node, the ingress and egress ports of the intermediate nodes, and the ingress and egress ports of the tail node.

[0050] In this embodiment, the first colored message is a message used for packet loss measurement, and it can be identified by the fields in the detection header of the message. The number of first colored messages routed to each port of each detection node on the path is reported to the centralized management and control platform for packet loss monitoring.

[0051] Step 102: Analyze the first information to achieve packet loss monitoring for one or more paths.

[0052] In this embodiment of the application, after receiving the first information reported by the node, the centralized management and control platform performs packet loss monitoring on each path based on the first information reported by the nodes on each path. Specifically, the centralized management and control platform determines the number of first-colored packets routed by the nodes on the path based on the statistical information of the first-colored packets reported by the nodes on the path, and further calculates the packet loss rate between adjacent nodes or between the first node and the last node.

[0053] Based on this, in an optional embodiment of this application, the step of analyzing the first information to achieve packet loss monitoring of one or more paths in the network includes:

[0054] For any one of the one or more paths, the number of first-colored packets routed by the nodes on the path is determined based on the statistical information of the first-colored packets reported by the nodes on the path.

[0055] The packet loss rate of the path is determined based on the number of first-colored packets routed to the nodes along the path.

[0056] In this embodiment, two detection modes are provided: an end-to-end detection mode, which monitors the packet loss rate between the head node and the tail node on the path; and a hop-by-hop detection mode, which monitors the packet loss rate between each node on the transmission path. In this embodiment, the end-to-end detection mode is a low-precision packet loss monitoring mode, and the hop-by-hop detection mode is a high-precision packet loss monitoring mode. In practical applications, low-precision packet loss detection can be performed on the path first. If the packet loss rate between the head node and the tail node on the path is greater than a preset threshold, then the high-precision hop-by-hop detection mode can be used to locate the fault point in the network, i.e., the node causing the high packet loss rate.

[0057] Based on this, in an optional embodiment of this application, determining the packet loss rate of the path based on the number of first-colored packets routed to nodes on the path includes:

[0058] The packet loss rate between the head and tail nodes of the path is determined based on the number of first-colored packets routed at the head and tail nodes of the path; or,

[0059] The packet loss rate between the head node, intermediate node, and tail node of the path is determined based on the number of first-colored packets routed at the head node, intermediate node, and tail node of the path.

[0060] In this embodiment of the application, determining the packet loss rate between the head node, intermediate node, and tail node of the path includes: determining the packet loss rate from the head node inlet port to the head node outlet port, the packet loss rate from the head node outlet port to the intermediate node inlet port, the packet loss rate from the intermediate node inlet port to the intermediate node outlet port, the packet loss rate from the intermediate node outlet port to the tail node inlet port, and the packet loss rate from the tail node inlet port to the tail node outlet port, etc.

[0061] In this embodiment, the latency of multiple paths can also be monitored. This is achieved by analyzing the statistical information of the second-colored packets reported by each node along the path, thus enabling latency monitoring of one or more paths. The statistical information of the second-colored packets includes: the timestamp information of the second-colored packets and the sequence number of the second-colored packets. Here, the timestamp information of the second-colored packets includes the timestamp information of a node receiving and / or sending the second-colored packets, i.e., the timestamp information of the second-colored packets passing through the node's ingress port and / or egress port; the sequence number of the second-colored packets is used to distinguish different second-colored packets, enabling detailed latency statistics for the second-colored packets.

[0062] Based on this, in an optional embodiment of this application, the first information further includes: statistical information of the second stained message; the statistical information of the second stained message includes: timestamp information of the second stained message and sequence number of the second stained message; the second stained message is a message used for delay measurement; the method further includes:

[0063] The first information is analyzed to enable latency monitoring of the one or more paths.

[0064] In this embodiment, two detection modes are provided: an end-to-end detection mode, which monitors the packet loss rate between the head node and the tail node on the path; and a hop-by-hop detection mode, which monitors the packet loss rate between each node on the transmission path. In this embodiment, the end-to-end detection mode provides low-precision latency monitoring, while the hop-by-hop detection mode provides high-precision latency monitoring. In practical applications, low-precision latency detection can be performed on the path first. If the latency between the head node and the tail node of the path exceeds a preset threshold, then the high-precision hop-by-hop detection mode can be used to locate the fault point in the network, i.e., the node causing the high latency.

[0065] Based on this, in an optional embodiment of this application, the step of analyzing the first information to achieve latency monitoring of the one or more paths includes:

[0066] For any one of the one or more paths, the time delay between the head node and the tail node of the path is determined based on the statistical information of the second-colored packets of the head node and tail node of the path; or,

[0067] Based on the statistical information of the second-colored messages reported by the head node, intermediate node and tail node of the target path, the time delay between the head node, intermediate node and tail node of the target path is determined.

[0068] In this embodiment of the application, determining the time delay between the head node, intermediate node, and tail node of the path includes: determining the time delay from the head node inlet port to the head node outlet port, the time delay from the head node outlet port to the intermediate node inlet port, the time delay from the intermediate node inlet port to the intermediate node outlet port, the time delay from the intermediate node outlet port to the tail node inlet port, and the time delay from the tail node inlet port to the tail node outlet port, etc.

[0069] In this embodiment of the application, in order to reduce the processing pressure of the centralized management and control platform, for latency detection, only the first message of the detection flow entering the new path is stained with latency, and each node only needs to report the statistical information of the second stained message of the latency-stained message.

[0070] Based on this, in one optional embodiment of this application, the second dyeing message is the first message of the detection flow entering the new path within the current detection cycle.

[0071] For example, detection flow 1 contains four data packets, namely data packet 1, data packet 2, data packet 3 and data packet 4; data packet 1 and data packet 2 enter path 1, which is the new path for the detection flow. Data packet 1 enters path 1 before data packet 2, so data packet 1 is colored for delay measurement, but data packet 2 is not colored for delay measurement; data packet 3 and data packet 4 enter path 2, which is the new path for the detection flow. Data packet 3 enters path 2 before data packet 4, so data packet 3 is colored for delay measurement, but data packet 4 is not colored for delay measurement.

[0072] Figure 2 Schematic diagram of the implementation process of the path monitoring method provided in the embodiments of this application Figure 2 ,like Figure 2 As shown, this embodiment provides a path monitoring method applied to a first node, the method comprising the following steps:

[0073] Step 201: Encapsulate the detection information in the message of the first detection stream; the detection information includes one or more of the following: the flow identifier of the service under test, the packet loss measurement coloring identifier, the service flow direction identifier, the coloring period, the detection mode, and the sequence number.

[0074] In this embodiment, the first node can serve as the head node on the path, encapsulating a detection header into a specific packet based on the five-tuple information of the detection flow. In this embodiment, the five-tuple information includes: source IP address, destination IP address, source port number, destination port number, and transport layer protocol.

[0075] The path monitoring method provided in this application embodiment can be applied to a GSE network. The first node can be a Global Scheduling Processor (GSP), and the first node encapsulates the detection information after the GSE header.

[0076] In this embodiment of the application, within a detection cycle, the packets in the detection stream are colored the same, while the packets in adjacent detection cycles are colored differently, which is used to distinguish the detection packets in different cycles.

[0077] In this embodiment, the detection mode includes two modes: an end-to-end detection mode, which monitors the packet loss rate between the head node and the tail node on the path; and a hop-by-hop detection mode, which monitors the packet loss rate between each node on the transmission path. In this embodiment, the end-to-end detection mode is a low-precision monitoring mode, and the hop-by-hop detection mode is a high-precision monitoring mode. In practical applications, the path can be first detected with low precision. If the packet loss rate between the head node and the tail node of the path is greater than a preset threshold, then the high-precision hop-by-hop detection mode can be used to locate the fault point in the network, i.e., the node causing the high packet loss rate.

[0078] In this embodiment of the application, the detection mode corresponding to the detection stream can be pre-configured at the first node or configured through a centralized management and control platform.

[0079] In this embodiment, the service flow direction identifier includes forward and reverse; when the service flow direction identifier is reverse, the tail node on the path needs to trigger reverse flow detection based on the forward detection flow quintuple information.

[0080] In this embodiment of the application, the flow identifier of the tested service is unique within the device, and when combined with the Source General Service Point Identifier (SGSP-ID), it is globally unique within the detection domain.

[0081] Step 202: Report the first information corresponding to the first detection flow to the centralized management and control platform; the first information includes: node port information and statistical information of the first colored message; the node port information represents the path to which the node port belongs; the statistical information of the first colored message includes: the number of the first colored message; the first colored message is a message used for packet loss measurement.

[0082] In this embodiment of the application, when the detection mode of the detection flow is end-to-end detection mode, the first node only reports the first information corresponding to the first detection flow of the inbound port route; when the detection mode of the detection flow is hop-by-hop detection mode, the first node reports the first information corresponding to the first detection flow of the inbound port route and the first information corresponding to the first detection flow of the outbound port route.

[0083] In this embodiment of the application, path delay monitoring can also be implemented. Delay coloring is applied to multiple packets in the detection flow to cover multiple paths traversed by the detection flow. The delay-colored packets are numbered so that intermediate nodes can distinguish the delay-colored packets for the tail node.

[0084] Based on this, in an optional embodiment of this application, if the message is the first message of the first detection flow entering the new path within the current detection cycle, the detection information of the message further includes: a delay measurement coloring identifier; the first information further includes: statistical information of the second coloring message; the statistical information of the second coloring message includes: the timestamp information of the second coloring message and the sequence number of the second coloring message; the second coloring message is a message used for delay measurement.

[0085] Step 203: Send the message of the first detection stream, which encapsulates the detection information, to the intermediate node.

[0086] The first node distributes the first detection stream to one or more intermediate nodes on the path through load balancing.

[0087] In this embodiment of the application, the first node can also be the tail node on the path. When it receives the second detection stream containing the detection information sent by the intermediate node on the path, it reports the first information to the centralized management and control platform according to the detection information.

[0088] Based on this, in one optional embodiment of this application, a message of a second detection stream encapsulated with detection information is received; the detection information includes one or more of the following: the flow identifier of the service under test, the packet loss measurement coloring identifier, the delay measurement coloring identifier, the service flow direction identifier, the coloring period, the detection mode, and the sequence number;

[0089] The system reports the first information corresponding to the second detection flow to the centralized management platform. The first information includes one or more of the following: node port information, statistical information of the first stained packet, and statistical information of the second stained packet. The node port information represents the path to which the node port belongs. The statistical information of the first stained packet includes the number of first stained packets. The first stained packet is a packet used for packet loss measurement. The statistical information of the second stained packet includes the timestamp information of the second stained packet and the sequence number of the second stained packet. The second stained packet is a packet used for latency measurement.

[0090] In this embodiment, when the detection flow's detection mode is end-to-end detection mode, the first node only reports the first information corresponding to the first detection flow of the outgoing port route; when the detection flow's detection mode is hop-by-hop detection mode, the first node reports the first information corresponding to the second detection flow of the incoming port route and the first information corresponding to the second detection flow of the outgoing port route. It can be understood that when the first node is the head node on the path, the outgoing port is the port connected to the network side; when the first node is the tail node on the path, the outgoing port is the port connected to the user side.

[0091] Figure 3 Schematic diagram of the implementation process of the path monitoring method provided in the embodiments of this application Figure 3 ,like Figure 3 As shown, this embodiment provides a path monitoring method applied to intermediate nodes, the method including the following steps:

[0092] Step 301: Receive a message encapsulated with detection information; the detection information includes one or more of the following: flow identifier of the service under test, packet loss measurement coloring identifier, delay measurement coloring identifier, service flow direction identifier, coloring period, detection mode, and sequence number.

[0093] In this embodiment of the application, the path monitoring method can be applied to the GSE network, and the intermediate node can be the Global Scheduling Fabirc (GSF).

[0094] In this embodiment, the detection mode includes two modes: an end-to-end detection mode, which monitors the packet loss rate and / or latency between the head node and the tail node on the path; and a hop-by-hop detection mode, which monitors the packet loss rate and / or latency between each node on the transmission path. In this embodiment, the end-to-end detection mode is a low-precision monitoring mode, while the hop-by-hop detection mode is a high-precision monitoring mode. In practical applications, a low-precision detection of the path can be performed first. If the packet loss rate and / or latency between the head node and the tail node of the path exceeds a preset threshold, then the high-precision hop-by-hop detection mode is used to locate the fault point in the network, i.e., the node causing the high packet loss rate.

[0095] In this embodiment, the service flow direction identifier includes forward and reverse; when the service flow direction identifier is reverse, the tail node on the path needs to trigger reverse flow detection based on the forward detection flow quintuple information.

[0096] In this embodiment of the application, the flow identifier of the tested service is unique within the device, and when combined with the SGSP-ID, it is globally unique within the detection domain.

[0097] In this embodiment of the application, the serial number is used to identify the number of the delay measurement coloring message, and is used by the node to distinguish the delay measurement coloring messages on different paths.

[0098] Step 302: Report the first information to the centralized management and control platform; the first information includes one or more of the following: node port information, statistical information of the first colored message, and statistical information of the second colored message; the node port information represents the path to which the node port belongs; the statistical information of the first colored message includes: the number of the first colored message; the first colored message is a message used for packet loss measurement; the statistical information of the second colored message includes: the timestamp information of the second colored message and the sequence number of the second colored message; the second colored message is a message used for delay measurement.

[0099] In this embodiment, the intermediate stage reports the first information according to the detection mode. When the detection mode is end-to-end mode, the intermediate node does not need to report the first information. When the detection mode is hop-by-hop detection mode, the intermediate node reports the first information. Here, the intermediate node needs to report the first information of the detection flow of the intermediate node's ingress port and egress port respectively.

[0100] Step 303: Send the message containing the detection information to the tail node.

[0101] The path monitoring method provided in this application embodiment can be applied to GSE network scenarios, see reference. Figure 4 , Figure 4 This is a schematic diagram of the GSE network architecture provided in the embodiments of this application, such as... Figure 4 As shown, GSP1 is the head node, GSF1, GSF2, and GSF3 are intermediate nodes, and GSP2 is the tail node. GSP1 encapsulates the message with a GSE visualization header IOAM based on the five-tuple information, placing the detection information before the GSE header. The detection flow is then forwarded through a message container. Specifically, data packets 1 and 2 of detection flow 1 are forwarded in message container 1 via GSF1; data packets 3 and 1 of detection flow 2 are forwarded in message container 2 via GSF2; and data packets 2 and 3 of detection flow 2 are forwarded in message container 3 via GSF3. GSP2 decapsulates the message and restores the original message. GSP1, GSF1, GSF2, GSF3, and GSP2 collect the first information corresponding to the message by matching the detection information and report this first information to the centralized management platform.

[0102] The end-to-end detection mode detects the packet loss rate and / or latency from the ingress port of GSP1 to the egress port of GSP2. The GSP node performs statistics based on the five-tuple information of the detection flow, encapsulates the corresponding detection information in the GSE header of the packet, and selects multiple packets for latency coloring within a detection period i to cover multiple paths. Simultaneously, the multiple latency-colored packets within a period need to be numbered so that subsequent packets can be identified by sequence number at the destination GSP.

[0103] The hop-by-hop detection mode detects the packet loss rate and / or latency between the ingress port of GSP1 and the egress port of GSP1, the egress port of GSP1 and the ingress port of GSF1, the egress port of GSP1 and the ingress port of GSF2, the egress port of GSP1 and the ingress port of GSF3, the egress port of GSF1 and the ingress port of GSP2, the egress port of GSF2 and the ingress port of GSP2, and the egress port of GSF3 and the ingress port of GSP2.

[0105] refer to Figure 6 , Figure 6 This is a schematic diagram of path monitoring under end-to-end detection mode provided in the embodiments of this application, such as... Figure 6 As shown, GSP1 sets all packet loss markers within period i to 0, and all packet loss markers within period i+1 to 1; it performs delay marking on the first three packets within period i, and on the first three packets within period i+1; packet ① goes through GSF1, packet ② goes through GSF2, and packet ③ goes through GSF3. The three delay-marked packets can cover three paths, and finally, the status of each link can be analyzed based on the delay information of multiple links; the GSF node, based on the detection mode in the detection information carried by the packet, when the detection mode is characterized as end-to-end detection mode, does not perform detection on the detection flow and does not report the first information to the centralized management platform; the GSP2 node, based on the flow marker in the GSE extension header, performs delay and packet loss statistics on the detection flow at the GSP2 outgoing interface within the marking period, and will report the first information to the centralized management platform.

[0106] refer to Figure 7 , Figure 7 This is a schematic diagram of path monitoring in hop-by-hop detection mode provided in the embodiments of this application, such as... Figure 7 As shown, GSP1 sets all packet loss markers within period i to 0, and all packet loss markers within period i+1 to 1; it performs delay marking on the first three packets within period i, and on the first three packets within period i+1; packet ① goes through GSF1, packet ② goes through GSF2, and packet ③ goes through GSF3. The three delay-marked packets can cover three paths. Finally, the status of each link can be analyzed based on the delay information of multiple links to obtain network quality information; GSP1 reports the first information of the detected inbound port to the centralized management platform; at the same time, because it is distributed per packet container, GSP1 needs to report the first information of the detected flow corresponding to the GSP1 outbound port and the first information of the detected flow corresponding to the GSP1 outbound port to the centralized management platform. According to the detection mode in the detection information carried in the message, when the detection mode is characterized as hop-by-hop detection mode, the GSF node reports the first information of the detection flow corresponding to the GSF ingress port and GSF egress port to the centralized management and control platform; the GSP2 node reports the first information of the detection flow corresponding to the GSP2 ingress port and GSP2 egress port to the centralized management and control platform based on the detection flow.

[0107] In this embodiment of the application, for the end-to-end detection mode, the centralized management and control platform determines the number of packet loss-colored packets in the source GSP and destination GSP routes on the path based on the first information reported by the source GSP and destination GSP on the path, and then calculates the packet loss rate of the path; the centralized management and control platform determines the timestamp information of the delay-colored packet in the source GSP and destination GSP based on the sequence number of the delay-colored packet in the detection flow reported by the source GSP and destination GSP on the path, and calculates the end-to-end delay of the path.

[0108] In this embodiment of the application, for the hop-by-hop detection mode, the centralized management and control platform determines the number of packet loss-colored packets in the source GSP, GSF, and destination GSP routes on the path based on the first information reported by the source GSP, GSF, and destination GSP on the path, and then calculates the packet loss rate between each node on the path; the centralized management and control platform determines the timestamp information of the delay-colored packet in the source GSP, GSF, and destination GSP based on the sequence number of the delay-colored packet in the detection flow reported by the source GSP, GSF, and destination GSP on the path, and calculates the delay between each node on the path. Here, the packet loss rate and delay between each node also include the packet loss rate and delay between the node's own ingress port and egress port.

[0109] In this embodiment, the centralized management platform can also analyze the reasons for high packet loss rate or high latency on the path. Specifically, each node on the path reports local information and GSE information to the centralized management platform. The local information includes: packet transmission and reception statistics, priority-based flow control (PFC) packet transmission and reception statistics, explicit congestion notification (ECN) packet statistics, and packet loss statistics. The GSE information includes: Dynamic Global Scheduling Queue (DGSQ) authorization information and packet container information. Based on the local information and DGSQ authorization information of each node, the centralized management platform accurately analyzes whether the packet loss in the container is due to insufficient authorization or other reasons.

[0110] In this embodiment of the application, after the message container arrives at the target GSP node in the GSE network, the GSP node needs to sort the message container before it is sent out. To avoid the data packet being too large in the sorting buffer on the destination GSP side, a threshold can be set. When a certain threshold is exceeded, the message container is forced to be sent out.

[0111] The path monitoring method provided in this application embodiment sets the detection header format and encapsulation method of the GSE basic header. For multi-path transmission, it provides two detection modes: end-to-end detection and hop-by-hop detection. It can perform two-point or multi-point network detection according to the actual situation, accurately locate fault points, and promptly detect network problems, thereby achieving effective network operation and maintenance and management. Furthermore, for latency monitoring, each node only needs to report the latency and path information of the first packet of the detection flow entering the new path within the detection period, which greatly reduces the amount of data processing and reduces the processing pressure on the centralized management and control platform.
