Problems solved by technology

[0004] The Fiber Shortest Path First (Fabric Shortest Path First, FSPF) protocol is a common FC protocol used to implement the FC dynamic routing function. Therefore, in order to achieve FCOE, it is usually necessary in the prior art to target the Ethernet carrying the FC protocol. Corresponding FSPF system is developed, resulting in higher development cost of FCOE

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0033] In the embodiment of the present invention, the intermediate system to intermediate system (Intermediate System to Intermediate System, ISIS) protocol used to support IPv4 and IPv6 in the Ethernet is improved, so that the improved ISIS protocol can realize the FC dynamic routing function, Therefore, there is no need to develop an additional FSPF system in order to realize FCOE, thereby reducing the development cost required to realize FCOE.

[0034] The ISIS protocol is an intra-domain dynamic routing protocol designed for the Connectionless Network Protocol (CLNP) under the Open System Interconnect (OSI) protocol stack, and has good scalability.

[0035] The ISIS network can be divided into two levels: Level-1 and Level-2. Level-1 refers to the ...

Abstract

The invention provides a route generation method and a route generation device for fiber channel over Ethernet (FCOE). By means of improvement on Hello messages of an intermediate system to intermediate system (ISIS) protocol and type-length-value (TLV) coding information carried by a link state protocol (LSP) data unit, the route generation method and the route generation device can achieve neighbor discovery of a fiber channel (FC) protocol with the help of the Hello messages of the ISIS protocol and synchronously achieve link information synchronization of the FC protocol with the help of the LSP of the ISIS protocol. Therefore, generation of FC route can be achieved without the need of a fabric shortest path first (FSPF) system, and the FCOE can be achieved by low cost.

Description

technical field [0001] The present invention relates to routing technology, in particular to a route generation method and device for realizing Ethernet bearing Fiber Channel (Fabric Channel Over Ethernet, FCOE). Background technique [0002] The core idea of ​​FCOE is to carry the Fiber Channel (Fabric Channel, FC) protocol on the Ethernet, so that the Ethernet link can be used to replace the FC, and then the integration and unification of the network can be realized. [0003] Correspondingly, the realization of FCOE requires that the network equipment in the Ethernet can not only support various original protocols in the Ethernet, but also need to support various FC protocols for realizing functions such as FC dynamic routing. [0004] The Fiber Shortest Path First (Fabric Shortest Path First, FSPF) protocol is a common FC protocol used to implement the FC dynamic routing function. Therefore, in order to achieve FCOE, it is usually necessary in the prior art to target the ...
