FORWARDING TRAFFIC FLOW IN INTELLIGENT RESILIENT FRAMEWORK SYSTEM
First Claim
1. A method for forwarding service messages in an Intelligent Resilient Framework (IRF) system, comprising:
- allocating each member device in the IRF system to at least two virtual devices, and configuring at least one stack link for each virtual device in order to connect interface boards among different member devices; and
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, forwarding the service message via the at least one stack link configured for the virtual device of that interface board.

Abstract
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.

7. A member device in an Intelligent Resilient Framework (IRF) system, comprising:
- at least one control board and multiple interface boards;
wherein each control board is shared by multiple virtual devices, each interface board is allocated to a virtual device among the multiple virtual devices, and at least one stack link is configured for each virtual device in order to connect interface boards between the member device and another member device in the IRF system; and each of the multiple interface boards is to receive a service message of the virtual device to which that interface board corresponds, and forward the service message via the at least one stack link configured for the virtual device to which that interface board corresponds if it is determined according to a forwarding entry of the interface board that the service message is to be transmitted to the another member device. - View Dependent Claims (8, 9, 10, 11, 12)
