【摘要】：隨著互聯(lián)網(wǎng)信息的持續(xù)增長(zhǎng),網(wǎng)絡(luò)服務(wù)器需要更多的空間儲(chǔ)存增長(zhǎng)的信息,服務(wù)器儲(chǔ)存“外部化”這一概念應(yīng)運(yùn)而生。為了實(shí)現(xiàn)服務(wù)器儲(chǔ)存“外部化”,工程師們提出了存儲(chǔ)網(wǎng)絡(luò)(SAN,Storage Area Networks)的概念。存儲(chǔ)網(wǎng)絡(luò)(SAN)的最大特點(diǎn)就是將網(wǎng)絡(luò)和設(shè)備的通信協(xié)議與傳輸?shù)奈锢斫橘|(zhì)分隔開(kāi)。存儲(chǔ)網(wǎng)絡(luò)(SAN)的支撐技術(shù)是Fabric Channel(FC)技術(shù),這是ANSI為網(wǎng)絡(luò)和通道I/O接口建立的一個(gè)標(biāo)準(zhǔn)集成。 在Fabric Channel(FC)的網(wǎng)絡(luò)中,FC交換機(jī)通常認(rèn)為是可以被信任的,因?yàn)镕C的各個(gè)節(jié)點(diǎn)設(shè)備在和其他的網(wǎng)絡(luò)設(shè)備通信之前,需要先進(jìn)行登錄操作。而且FC的鏈接是點(diǎn)對(duì)點(diǎn)的方式,因此FC交換機(jī)可以完全控制各節(jié)點(diǎn)設(shè)備的接入與通信。這種組網(wǎng)方式雖然大大增強(qiáng)了網(wǎng)絡(luò)的安全性及可控性,但組網(wǎng)的靈活性卻大打折扣。 FCoE(Fibre Channel over Ethernet)網(wǎng)絡(luò)的出現(xiàn)彌補(bǔ)了這一遺憾,它增加了Fabric組網(wǎng)的靈活性�？蛇@又帶來(lái)了新的問(wèn)題：由于ENode和FCF之間可以存在以太網(wǎng)橋設(shè)備,不再是傳統(tǒng)意義上的點(diǎn)對(duì)點(diǎn)連接,因此FC交換機(jī)變得不能像以前一樣有效的控制各個(gè)節(jié)點(diǎn)。 FIP-SNOOPING協(xié)議完美解決了這個(gè)問(wèn)題,它是應(yīng)用于FCoE邊緣設(shè)備的一種安全協(xié)議。該協(xié)議運(yùn)行在Transit交換機(jī)(以太網(wǎng)橋設(shè)備)上,通過(guò)對(duì)MAC地址的檢測(cè)限定ENode報(bào)文能且僅能發(fā)送給FCF交換機(jī),以及限定的FCF報(bào)文僅能發(fā)送給ENode等等,從而使FC交換機(jī)依舊可以有效控制各個(gè)節(jié)點(diǎn)。 本文的主要工作是研究并實(shí)現(xiàn)了FIP-SNOOPING協(xié)議。該協(xié)議開(kāi)發(fā)主要包括：FCoE模式切換、FIP-SNOOPING協(xié)議開(kāi)發(fā)以及分布式開(kāi)發(fā)三大部分。其中分布式開(kāi)發(fā)并不是新功能的開(kāi)發(fā),而是為了支持新功能在分布式交換機(jī)上正常運(yùn)行進(jìn)行的相關(guān)輔助支持進(jìn)程的開(kāi)發(fā),因此并非本文重點(diǎn)。本文首先闡述課題開(kāi)發(fā)相關(guān)協(xié)議,包括FCoE協(xié)議、FIP協(xié)議,以及FCF、NPV和Transit路由器的模式和分布式開(kāi)發(fā)的相關(guān)知識(shí)。其次,本文將具體闡明FIP-SNOOPING模塊和FCoE模式切換模塊需求分析,并詳細(xì)分析FIP-SNOOPING協(xié)議總體流程,這也是本文的重點(diǎn)所在。接下來(lái),本文會(huì)詳細(xì)闡釋FIP-SNOOPING模塊功能設(shè)計(jì)、數(shù)據(jù)結(jié)構(gòu)設(shè)計(jì)和模塊功能具體實(shí)現(xiàn),以及FCoE模式切換模塊功能的設(shè)計(jì)與具體實(shí)現(xiàn)。最后,本文將給出對(duì)開(kāi)發(fā)內(nèi)容的測(cè)試,證明本次開(kāi)發(fā)的成功性和完備性。
[Abstract]:With the continuous growth of Internet information, web servers need more space to store and grow information, and the concept of "externalization" of server storage emerges as the times require. In order to externalize server storage, engineers put forward the concept of storage network storage Area networks. The main feature of Storage Network (San) is to separate the communication protocol of network and device from the physical medium of transmission. Storage Network (San) is supported by Fabric Channel FCtechnology, which is a standard integration established by ANSI for network and channel I / O interface. In the network of Fabric Channel, the FC switch is generally considered to be trustworthy because each node device of the FC needs to log in before communicating with other network devices. The FC link is a point-to-point mode, so the FC switch can completely control the access and communication of each node device. Although the security and controllability of the network are greatly enhanced, the flexibility of networking is greatly reduced. The emergence of FCoE(Fibre Channel over Ethernet) network makes up for this regret, it increases the flexibility of Fabric networking. But this brings a new problem: because there can be Ethernet bridge equipment between ENode and FCF, which is no longer the traditional point-to-point connection, the FC switch can not control each node as effectively as before. The FIP-SNOOPING protocol solves this problem perfectly. It is a security protocol applied to FCoE edge devices. The protocol runs on the Transit switch (Ethernet Bridge device), which limits the ENode message to be sent to the FCF switch only by detecting the MAC address, and the limited FCF message can only be sent to the ENode, and so on. So that the FC switch can still effectively control each node. The main work of this paper is to study and implement FIP-SNOOPING protocol. The protocol development includes three parts: FIP-SNOOPING protocol and distributed development. Distributed development is not the development of new functions, but to support the development of related auxiliary support processes for the normal operation of new functions on distributed switches, so it is not the focus of this paper. This paper first describes the related protocols, including FCoE protocol and FIP protocol, as well as the patterns of FCFNPV and Transit routers and the knowledge of distributed development. Secondly, this paper will clarify the requirement analysis of FIP-SNOOPING module and FCoE mode switching module, and analyze the overall flow of FIP-SNOOPING protocol in detail, which is also the focus of this paper. Next, this article will elaborate the FIP-SNOOPING module function design, the data structure design and the module function realization, as well as the FCoE mode switching module function design and the concrete realization. Finally, the test of the development content is given to prove the success and completeness of the development.
