Method and System for Information Interaction Among Systems in the Same End in DRNI

摘要

Disclosed are a method and system for information interaction between systems in a same portal in a distributed resilient network interconnection, wherein the method is applied to each system in an portal in a link aggregation group, including: sending a distributed relay control protocol (DRCP) message through an intra-portal interface, wherein at least system information of a present system is carried; after receiving a DRCP message sent by an adjacent system, if it is determined that the present system and the adjacent system can form one portal in the distributed resilient network interconnection, determining an operational Key value of the present system. The system includes: a sending state machine, a receiving state machine, a negotiating state machine, a synchronizing state machine and a periodic sending state machine.

1. A method for information interaction between systems in a same portal in a distributed resilient network interconnection, used in each system in a portal of a link aggregation group, comprising:
sending a distributed relay control protocol (DRCP) message via an intra-portal interface, wherein at least system information of a present system is carried; after receiving a DRCP message sent by an adjacent system, if it is judged that the present system and the adjacent system can form an portal of the distributed resilient network interconnection, determining an operational Key value of the present system.
