Abstract

This invention discloses a structuring method for a performance test environment of spring packet rings including: a RPR primary node receives an order for requiring entering into a test enronment, the primary node broadcasts a function message carrying with identification for closing interruption process to close it, a slave node closes interruption process based on the ID, the primary node broadcasts the function message with the ID of stopping sending control message and equity message and stops transmitting the messages, the slave node stops transmitting the messages based on the ID, which constructs an environment for accurately testing its performance for actual RPR networking, that is convenient for manufacturers to explain the performance of RPR equipments accurately and business runners to test them accurately. This invention also discloses the RPR system, primary nodes and slave nodes.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for constructing an elastic packet ring performance test environment, an elastic packet ring system, a master node, and a slave node. Background technique [0002] Resilient Packet Ring (RPR, Resilient Packet Ring) is a new media access control (MAC, Media Access Control) layer technology defined by the IEEE802.17 working group, which combines Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) ) and the technical advantages of Ethernet, with multiple technical advantages such as less than 50ms protection switching, automatic topology discovery and high bandwidth utilization. [0003] Such as figure 1 As shown, the RPR topology adopts a bidirectional dual-fiber ring structure, and services can be transmitted on both the inner and outer rings, but the transmission directions are opposite. Each ring consists of a series of connected ...
