FORWARDING TRAFFIC FLOW IN INTELLIGENT RESILIENT FRAMEWORK SYSTEM

摘要

A method and member device for forwarding service messages in an Intelligent Resilient Framework (IRF) system and an IRF system. In the method, each member device in the IRF system is allocated to at least two virtual devices, and at least one stack link for each virtual device is configured in order to connect interface boards among different member devices. When it is determined according to a forwarding entry of an interface board in a first member device receiving a service message that the service message is to be transmitted to a second member device, the service message is forwarded via the at least one stack link configured for the virtual device of that interface board.
