Embodiment Construction

[0034]In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] The "unit" mentioned in this article refers to a logically divided functional structure, and the "unit" can be realized by pure hardware, or a combination of software and hardware.

[0036] Please refer to figure 1 , which shows a schematic structural diagram of the router 100 provided by an exemplary embodiment of the present invention. The router 100 includes: a processor 120 and a physical interface 140 connected to the processor 120 .

[0037] The physical interface 140 may be connected to physical interfaces of other devices to form one or more physical links. Router 100 is capable of sending or receiving packets using physical links. Wherein, the package may be a monitoring package or a data package.

[0038] For exampl...

Abstract

A performance monitoring method, device and router, belonging to the technical field of communication. The method includes: before the first physical interface of the router sends the first monitoring packet, the router determines the path of the first monitoring packet according to the forwarding table, the path includes the first LSP and the first PW overlapping on the first LSP; according to The path generates the first monitoring packet, the first monitoring packet is an MPLS packet, the MPLS label of the first monitoring packet is generated according to the first LSP, the PW label of the first monitoring packet is generated according to the first PW, and the PW label includes the first physical interface connected The first monitoring parameter of the first physical link, the second monitoring parameter of the first LSP, and the third monitoring parameter of the first PW; the first monitoring packet is sent from the first physical interface, and the router can pass a first monitoring packet at the same time Determining the network performance of the first physical link, the first LSP, and the first PW can reduce bandwidth occupation for network performance monitoring.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a performance monitoring method, device and router. Background technique [0002] Network performance is a measure of network quality, and network performance includes parameters such as packet loss rate and transmission delay. Currently, many networks need to monitor network performance. [0003] Taking Multiprotocol Label Switching (English: Multiprotocol Label Switching, MPLS) virtual private network (English: virtual private network, VPN) as an example, there are multiple routers in the MPLS VPN, and these multiple routers can establish multiple paths. It includes multiple physical links, a label switched path (English: Label Switched Path, LSP) overlapping (English: over) on these physical links, and a pseudowire (English: pseudowire, PW) overlapping on the LSP. When monitoring the network performance of MPLS VPN, the router needs to monitor the network performance ...
