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

The embodiment of the invention provides a route synchronization method and a device. The method comprises the steps that a first fiber channel over Ethernet edge forwarder (FEF) receives a whole network address request message sent by a second FEF, wherein the whole network address request message comprises a media access control (MAC) address and a fiber channel (FC) network segment of the second FEF; the first FEF analyzes the whole network address request message, obtains the MAC address and FC network segment of the second FEF, and stores the MAC address and FC network segment of the second FEF in a route table of the first FEF; and the first FEF returns a response message to the second FEF, wherein the response message comprises the MAC address and FC network segment of the first FEF. Through adoption of the route synchronization method and device, distributed route of a fiber channel over Ethernet (FCoE) connected with the same Ethernet domain is realized, so that the expandability of the FCoE is improved.

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 (FDF for short), and Data Center Bridging (DCB) network; among them, The cFCF is responsible for collecting the virtual link table entry information reported by the FDF, and performing routing calculation in a unified manner, and sending the generated routing table entry to each FDF; the FDF is responsible for realizing the local forwarding of the FCoE message, through VA Port) establishes virtual links with cFCF and FDF and maintains virtual link entry information loca...
