Problems solved by technology

[0003] In the route synchronization mechanism of the existing FCoE network, the cFCF needs to collect the table items reported by each FDF to build the network topology, so that all routes can be calculated and sent to all FDFs one by one. When the number of FDFs increases, the processing overhead of the cFCF Moreover, whenever FDFs change the topology structure due to going online and offline, cFCF needs to re-synchronize the FC routing information of the entire network. When the number of FDFs increases, the overhead for updating FC routing increases, resulting in poor network scalability. Difference

Embodiment Construction

[0040]In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] In a traditional FCoE network, the FCoE switch route synchronization mechanism is to set up a dedicated device (for example, cFCF) to perform network-wide route calculation and synchronization. The cFCF is responsible for centrally calculating all routes and delivering them to all FDFs one by one. To this end, the cFCF needs to collect the e...

Abstract

An embodiment of the present invention provides a route synchronization method and device, the method comprising: the first Ethernet Fiber Channel boundary forwarding device FEF receives the whole network address request message sent by the second FEF; the whole network address request message includes the The media access control MAC address and the Fiber Channel FC network segment of the second FEF; the first FEF parses the entire network address request message, obtains the MAC address and the FC network segment of the second FEF, and sends the The MAC address and FC network segment of the second FEF are stored in the routing table of the first FEF; the first FEF returns a response message to the second FEF; the response message includes the MAC address of the first FEF address and FC network segment. The routing synchronization method and device provided by the embodiments of the present invention realize distributed routing of FCoE networks connected to the same Ethernet domain, and improve the scalability of the FCoE network.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a route synchronization method and device. Background technique [0002] Fiber Channel over Ethernet (FCoE for short) technology is a network convergence technology that enables Fiber Channel over Ethernet (FC for short) and Ethernet to share a single, integrated network infrastructure. The existing FCoE network includes: Controlling FCoE Forwarder (cFCF for short), FCoE data-plane forwarder (FCoE Data-plane Forwarder, FDF for short), and data center bridging (DataCenter Bridging, DCB) network; among them, cFCF Responsible for collecting the virtual link entry information reported by the FDF, and uniformly perform routing calculations, and deliver the generated routing table entries to each FDF; the FDF is responsible for realizing the local forwarding of FCoE packets, through the Virtual Port) establish virtual links with cFCF and FDF and maintain virtual ...
