Abstract:
1. A control method of virtual link discovery in a Fibre Channel over Ethernet (FCoE) protocol system, the method being applied between Ethernet Nodes (E Nodes) and FCoE Forwarders (FCFs), wherein some of the ENodes and the FCFs are allocated to different virtual networks, the control method comprising: a1: an ENode sending, via a Virtual Node (VN) port of the ENode, an FCoE Initialization Protocol (FIP) Discovery Solicitation message to Virtual Fiber Channel (VFC) ports of the FCFs, the FIP Discovery Solicitation message carrying a virtual network ID (VN ID) of the VN port indicating which virtual network the VN port belongs to; a2: the ENode receiving, via the Virtual Node(VN) port, FIP Discovery Advertisement messages replied by the VFC ports of the FCFs, the FIP Discovery Advertisement messages carrying Virtual Network IDs (VN IDs) of the VFC ports indicating which Virtual Networks the VFC ports respectively belong to; a3: the ENode comparing the Virtual Network (VN ID) of the Virtual Node(VN) port with the VN IDs carried in the FIP Discovery Advertisement messages, and logging the VN node to a VFC port which has the same Virtual Network ID (VN ID) in preference to other VFC ports having different VN IDs, wherein the VN port establishes a virtual link with the VFC port belonging to the same Virtual Network in preference to the other VFC ports belonging to different Virtual Networks.
