Embodiment Construction

[0059] The embodiment of the present invention provides an end-to-end layer 2 network performance, packet loss rate, delay test method and network edge node device, and determines the destination port of the protocol message received by the switch chip of the network edge node device as the switch chip Connect to the CPU port of the CPU of the network edge node device, so that the protocol message is directly forwarded to the system software in the CPU through the CPU port, avoiding network risks during network testing.

[0060] Such as image 3 As shown, the embodiment of the present invention provides a method for testing end-to-end Layer 2 network performance, including:

[0061] S301. After the switching chip of the network edge node device receives the message, it performs message type matching, and when it is determined that the received message is a message conforming to the ACL rule of the received protocol message, it is determined that the received message is a proto...

Abstract

The embodiment of the invention provides a method for detecting end-to-end two-layer network performance, the packet loss probability and time delay and network fringe node equipment. A destination port of a protocol message received by an exchange chip of the network fringe node equipment is determined as a CPU port of a CPU which is located on the exchange chip and is connected with the network fringe node equipment, the protocol message is directly transmitted to system software in the CPU through the CPU port, and network risks occurring in network tests are avoided.

Description

technical field [0001] The invention relates to network communication technology, in particular to an end-to-end two-layer network performance, packet loss rate, time delay testing method and network edge node equipment. Background technique [0002] Service-Level Agreement (Service-Level Agreement, SLA) is a real-time network performance detection and statistics technology based on the application scenarios defined by Connectivity Fault Management (CFM). Detect and monitor network traffic to generate reports based on detection results. The key performance indicators (Key Performance Indicators, KPI) of SLA mainly include delay and packet loss rate, etc., which correspond to the delay / jitter test (Delay Measurements, DM) and packet loss rate test (Loss Measurements, LM) of SLA. Down Maintenance associations End Point (DOWN MEP) and Up Maintenance associations End Point (UP MEP) are two types of management activity entities that can send and process CFM messages. In practic...
