Problems solved by technology

[0008] It can be seen that this kind of scene detection effect is relatively simple, and it can only detect the connectivity between device C and device A.
[0009] Aiming at the problem that the detection effect of NNI PING is single in related technologies, no effective solution has been proposed yet

Embodiment Construction

[0029] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0030] The inventor found that, if a certain access device C in the above-mentioned L3VPN network continuously sends large-capacity NNI PING messages, for example, it may be a User Datagram Protocol (UDP) response Protocol (Echo Protocol, referred to as echo, mainly used for debugging and testing) messages, after being processed by the head node PE device A of the L2VPN and returned to the C device, and then through the tester or computer terminal connected to the C device You can obtain other useful information such as network throughput, packet loss rate, jitter and other performance indicators between the above two devices.

[0031] Based on the above considerations, in this embodiment, an implem...

Abstract

Disclosed are a method and apparatus for implementing an NNI PING. The method comprises: a first device receives a detection packet from a second device of an L3VPN, the first device being a head node PE of an L2VPN; the first device forwards the detection packet to a hardware chip for parsing; and the first device sends the parsed detection packet to the second device. By means of the present invention, the problem of a single detection result of the NNI PING in the related art is solved, so that the capacity, the processing depth and the processing efficiency of the detection packet can be greatly improved, thereby enabling the second device to, according to the received detection packet with larger capacity, judge the connectivity and obtain other useful information such as throughput, packet loss rate, jitter and other performance indexes of the network between the two devices.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for implementing a Network Node Interface (NNI for short) PING. Background technique [0002] In a Layer 2 Virtual Private Network (L2VPN for short) / Layer 3 Virtual Private Network (L3VPN for short) bridging network, operators often make a connection between the aggregation layer network and the access layer network. Check whether the network is connected between some devices. There will be such an application scenario, that is, an access device C in the L3VPN network sends a PING message to the head node of the L2VPN (Provider Edge, referred to as PE, an edge device in the backbone network, which is directly connected to the user's CE , which is responsible for the distribution of user routes and the management of VRF routing tables, and the forwarding layer implements service flow tunnel encapsulation and decapsulation) Device A is used to detect the conn...
