Description

Technical Field

[0001] This disclosure relates to the field of network technology and security, and in particular to a method and apparatus for packet loss statistics of a multi-layer protocol stack. Background Technology

[0002] The Y.1731 protocol, proposed by the ITU-T standards organization, is widely used for performance monitoring in Ethernet OAM (Operation Administration and Maintenance). Packet loss statistics are achieved by exchanging frames containing send / receive packet counter values ​​with network peers. However, the send / receive packet counter values ​​in this implementation represent the number of sent / received packets on a specific network link. Therefore, the implemented packet loss statistics only perform uniform statistics on a single link and do not target specific upper-layer protocol service packets. However, in actual network operation, network maintenance requires monitoring packet loss across multiple network layers, thus necessitating packet loss statistics for various upper-layer protocol packets in the OSI seven-layer model. Summary of the Invention

[0003] One technical problem this disclosure aims to solve is to provide a method and apparatus for packet loss statistics of multi-layer protocol stacks, which can realize packet loss statistics for various upper-layer protocol messages.

[0004] According to one aspect of this disclosure, a multi-layer protocol stack packet loss statistics method is proposed, comprising: sending a packet loss measurement message carrying a specified message layer digital segment and a specified message layer number of transmitted message to a destination; receiving a packet loss measurement response message carrying a specified message layer digital segment and a specified message layer number of received message sent by the destination; and performing packet loss statistics based on the transmitted message value and the received message value of the specified message layer number.

[0005] In some embodiments, the source identifies the layer number to which each service message belongs; reads the transmitted message value of the specified message layer using an extended local counter; and fills the transmitted message value of the specified message layer into the packet loss measurement message in accordance with the Y.1731 protocol.

[0006] In some embodiments, the destination identifies the layer number to which each service message belongs; reads the received message value of the specified message layer using an extended local counter based on the specified message layer number field; and fills the received message value of the specified message layer into the packet loss measurement response message in accordance with the Y.1731 protocol.

[0007] In some embodiments, when performing packet loss statistics for a dual-end multi-layer protocol stack, the messages sent by both the source and destination ends carry a specified message layer digital field, as well as the sent and received message values ​​of the local end and the peer end.

[0008] According to another aspect of this disclosure, a multi-layer protocol stack packet loss statistics device is also proposed, comprising: a measurement message sending unit configured to send a packet loss measurement message carrying a specified message layer digital segment and a specified message layer number to a destination; an acknowledgment message receiving unit configured to receive a packet loss measurement acknowledgment message carrying a specified message layer digital segment and a specified message layer number to a destination; and a packet loss statistics unit configured to perform packet loss statistics based on the specified message layer number and the received message number.

[0009] In some embodiments, the multi-layer protocol stack packet loss statistics device further includes: a message layer identification unit configured to identify the layer to which each service message belongs; an extended local counter configured to read the value of the sent message at a specified message layer; and a message filling unit configured to fill the sent message value at a specified message layer into the packet loss measurement message according to the Y.1731 protocol.

[0010] In some embodiments, the multi-layer protocol stack packet loss statistics device further includes: a message layer number identification unit configured to identify the layer number to which each service message belongs; an extended local counter configured to read the received message value of a specified message layer according to a specified message layer number segment; and a message filling unit configured to fill the received message value of a specified message layer into the packet loss measurement response message according to the Y.1731 protocol.

[0011] In some embodiments, when performing packet loss statistics for a dual-end multi-layer protocol stack, the messages sent by both the source and destination ends carry a specified message layer digital field, as well as the sent and received message values ​​of the local end and the peer end.

[0012] According to another aspect of this disclosure, a multi-layer protocol stack packet loss statistics device is also proposed, comprising: a memory; and a processor coupled to the memory, the processor being configured to execute the multi-layer protocol stack packet loss statistics method as described above based on instructions stored in the memory.

[0013] In some embodiments, a non-transitory computer-readable storage medium stores computer program instructions that, when executed by a processor, implement the multi-layer protocol stack packet loss statistics method described above.

[0014] In this embodiment of the disclosure, by extending the Y.1731 protocol, measurement frames containing message values ​​of a specified message layer are sent and received, and packet loss statistics are performed on messages of a specified layer. This solves the problem that the existing Y.1731 protocol can only perform unified packet loss statistics on all messages on the link, and realizes packet loss statistics for multi-layer protocol messages on the network link.

[0029] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0033] Figure 1 This is a flowchart illustrating some embodiments of the multi-layer protocol stack packet loss statistics method disclosed herein.

[0034] In step 110, the source sends a packet loss measurement message to the destination, which carries a specified message layer number field and the value of the sent message for the specified message layer number.

[0035] In some embodiments, the source identifies the layer number to which each service packet belongs. Then, the local counter is extended, and the value of the sent packets for the specified packet layer is read using the extended local counter. According to the Y.1731 protocol, the value of the sent packets for the specified packet layer is filled into the packet loss measurement packet.

[0036] In step 120, a packet loss measurement response message is received from the destination, carrying a received message value with a specified message layer number field and a specified message layer number.

[0037] In some embodiments, after receiving a packet loss measurement message, the destination identifies the layer number to which each service message belongs, reads the received message value of the specified message layer number using an extended local counter according to the specified message layer number field, and fills the received message value of the specified message layer number into the packet loss measurement response message in accordance with the Y.1731 protocol.

[0038] In step 130, packet loss statistics are performed based on the number of sent and received packets at the specified message layer.

[0039] In some embodiments, the packet loss statistics algorithm of the Y.1731 protocol is used to calculate packet loss for packets at a specified layer.

[0040] In the above embodiments, by extending the Y.1731 protocol, measurement frames containing message values ​​of a specified message layer are sent and received, and packet loss statistics are performed on messages of a specified layer, thereby achieving the purpose of quality monitoring of network multi-layer protocol messages.

[0041] Figure 2 This is a flowchart illustrating some other embodiments of the multi-layer protocol stack packet loss statistics method disclosed herein.

[0042] In step 210, the source end configures a packet loss statistics command for a specified layer via command line.

[0043] In step 220, the transmitted message value for the specified message layer is read using an extended local counter.

[0044] In some embodiments, the source and destination identify the layer number to which the service message belongs. When starting the Y.1731 packet loss statistics measurement, the source uses an extended local counter to read the sent message value for the specified message layer.

[0045] In step 230, the source end fills the packet loss statistics measurement frame according to the Y.1731 protocol.

[0046] In step 240, the specified message layer digital segment is filled into the packet loss statistics measurement frame according to the configuration command.

[0047] In some embodiments, such as Figure 3 As shown, a LayerTag field is added to the packet loss measurement message. This field is used to indicate the specified message layer to be counted.

[0048] In step 250, a packet loss statistics measurement frame with a specified message layer number is sent.

[0049] In step 260, after the destination receives the packet loss statistics measurement frame, it parses the message to obtain the specified message layer digital segment.

[0050] In step 270, the received message value of the specified message layer number is read using an extended local counter based on the specified message layer number field.

[0051] In step 280, the received message value of the specified message layer is filled into the packet loss measurement response message in accordance with the Y.1731 protocol.

[0052] In some embodiments, such as Figure 4 As shown, a LayerTag field is added to the packet loss measurement response message. This field is used to indicate the number of specified packet layers that have been counted.

[0053] In some embodiments, when performing packet loss statistics for a dual-end multi-layer protocol stack, the messages sent by both the source and destination ends carry a specified message layer digital field, as well as the sent and received message values ​​of the local end and the peer end.

[0054] like Figure 5 As shown, the source and destination exchange connectivity detection messages, which also carry a specified message layer digital segment.

[0055] In step 290, the destination sends a packet loss measurement response message to the source.

[0056] In step 2100, the source end calculates packet loss by comparing the transmitted and received message values ​​at a specified layer with those of the peer end using the packet loss statistics algorithm of the Y.1731 protocol.

[0057] In the above embodiments, when sending and receiving messages, the layer to which the message belongs is identified, the local counter is extended to record the number of messages sent and received at each layer, and a message layer marker field is added to the test message. By sending and receiving measurement frames containing specific layer counter values ​​and identifying the message layer, and by performing packet loss statistics for sending and receiving messages at specific layers, the problem that the Y.1731 protocol can only perform unified packet loss statistics for all messages on the link is solved, and packet loss statistics for multi-layer protocol messages on the network link are realized.
