【摘要】：以太网具有简单灵活、高性价比的特点,目前被广泛应用于各种通信场景中。而光纤通道(Fiber Channel,简称FC)凭借着高性能和高可靠性的优势,在存储局域网(StorageAreaNetwork,简称SAN)等高速通信领域占据着领导地位。对于如何实现这两种异构网络融合,前人有许多研究,也取得了一定的成果。但是不同的场景对于网络融合有着不同的需求。如何根据具体的场景和需求选择合适的网络融合方式,这成为摆在我们面前的现实问题。本文首先细致分析了 FC-Eth桥接方案,包括软硬件功能划分、桥接表的设计以及FC与UDP的协议转换等。该方法实现起来比较简单,但在大型网络中,手工配置桥接表需要占用大量时间。随后,本文提出了基于FCUDP-SAR引擎的网络融合方案以及基于FCoE协议的网络融合方案。基于FCUDP-SAR引擎的网络融合方案通过软硬件协同来实现FC协议栈和UDP协议栈。基于FCoE协议的网络融合方案则研究了 FC协议与FCoE协议如何进行相互转换,同时,为了使FCoE帧能够在以太网上传输,该方案还研究了 FIP协议。最后,本文给出了后面两种网络融合方案的具体实现,并进行了功能性测试。需要实现FC网络与以太网网络融合的场景有很多,其具体的实现方法也千差万别。本文所研究的三种网络融合方案有比较强的代表性,可以为解决实际工程问题提供相应的思路。
[Abstract]:Ethernet has been widely used in various communication scenarios because of its simplicity and flexibility and high cost-performance ratio. Fiber Channel (FCL), with its advantages of high performance and high reliability, plays a leading role in storage area network (San) and other high-speed communication fields. There are many researches on how to realize the convergence of these two heterogeneous networks, and some achievements have been made. However, different scenarios have different requirements for network convergence. How to choose the appropriate network fusion method according to the specific scenarios and needs has become a real problem in front of us. In this paper, the FC-Eth bridging scheme is analyzed in detail, including the partition of hardware and software, the design of bridging table and the protocol conversion between FC and UDP. This method is simple to implement, but it takes a lot of time to configure the bridge table manually in large network. Then, this paper proposes a network fusion scheme based on FCUDP-SAR engine and a network fusion scheme based on FCoE protocol. The network fusion scheme based on FCUDP-SAR engine realizes FC protocol stack and UDP protocol stack through hardware and software cooperation. The network fusion scheme based on FCoE protocol studies how to convert FC protocol and FCoE protocol. At the same time, in order to enable FCoE frames to be transmitted over Ethernet, the FIP protocol is also studied. Finally, the implementation of the latter two network convergence schemes is given, and the functional test is carried out. There are many scenarios that need to realize the convergence of FC network and Ethernet network. The three network fusion schemes studied in this paper have strong representativeness and can provide corresponding ideas for solving practical engineering problems.
