【摘要】：隨著網(wǎng)絡(luò)技術(shù)的飛速發(fā)展,在以數(shù)據(jù)為中心的網(wǎng)絡(luò)世界中,數(shù)據(jù)中心逐漸成為大多數(shù)企業(yè)的網(wǎng)絡(luò)的關(guān)鍵設(shè)施。為了實(shí)現(xiàn)網(wǎng)絡(luò)服務(wù)的可靠性,很多企業(yè)把數(shù)據(jù)中心分布在多個(gè)不同的地理位置。為了增強(qiáng)多個(gè)數(shù)據(jù)中心之間資源的流動(dòng)性和管理的靈活性,數(shù)據(jù)中心必須在不損害整體網(wǎng)絡(luò)穩(wěn)定性的情況下提供異地?cái)?shù)據(jù)中心之間的第二層網(wǎng)絡(luò)連接。由于傳統(tǒng)上二層轉(zhuǎn)發(fā)只能限制在局域網(wǎng)內(nèi)基于MAC地址進(jìn)行轉(zhuǎn)發(fā),所以擴(kuò)展二層域的一個(gè)重要方面是實(shí)現(xiàn)異地站點(diǎn)間MAC地址的通告。本文結(jié)合數(shù)據(jù)中心間二層擴(kuò)展的要求對(duì)標(biāo)準(zhǔn)的ISIS協(xié)議進(jìn)行了改造,提出了一種基于ISIS協(xié)議的異地?cái)?shù)據(jù)中心間的MAC地址通告方案。 本文在某公司的軟件開(kāi)發(fā)平臺(tái)上實(shí)現(xiàn)了異地?cái)?shù)據(jù)中心間的MAC地址通告方案。軟件采用多線程機(jī)制,包括系統(tǒng)事件處理、鄰居維護(hù)、LSP維護(hù)、路由維護(hù)四個(gè)線程模塊。其中系統(tǒng)事件處理負(fù)責(zé)系統(tǒng)運(yùn)行的準(zhǔn)備、調(diào)度工作；鄰居維護(hù)線程負(fù)責(zé)站點(diǎn)的鄰居關(guān)系以及本地MAC地址信息的維護(hù)；LSP維護(hù)線程負(fù)責(zé)LSP報(bào)文的生成、同步以及LSP中MAC信息的提��；路由維護(hù)線程負(fù)責(zé)遠(yuǎn)端MAC地址信息的處理和下刷。 本文最后在實(shí)際設(shè)備上對(duì)軟件功能進(jìn)行了測(cè)試。測(cè)試結(jié)果表明本地設(shè)備的MAC地址信息通告到了異地設(shè)備,本地設(shè)備上建立了關(guān)于異地設(shè)備的MAC地址信息轉(zhuǎn)發(fā)表,達(dá)到了預(yù)期的MAC地址通告要求。
[Abstract]:With the rapid development of network technology, data center has gradually become the key facility of most enterprises in the data-centric network world. In order to realize the reliability of network service, many enterprises distribute data centers in many different geographical locations. In order to enhance the mobility of resources and the flexibility of management, the data center must provide the second layer network connection between the different data centers without compromising the stability of the whole network. Traditionally, layer 2 forwarding can only be done in LAN based on MAC address, so an important aspect of extending layer 2 domain is to realize the notification of MAC address between different sites. In this paper, the standard ISIS protocol is modified according to the requirement of two-layer extension between data centers, and a MAC address notification scheme between data centers is proposed based on ISIS protocol. In this paper, the MAC address notification scheme between different data centers is implemented on the software development platform of a company. The software adopts multithread mechanism, including system event processing, neighbor maintenance LSP maintenance, route maintenance four thread modules. The system event processing is responsible for the preparation and scheduling of the system, the neighbor maintenance thread is responsible for the neighbor relationship of the site and the local MAC address information maintenance thread is responsible for the generation of the LSP message. Synchronization and MAC information extraction from LSP; routing maintenance thread is responsible for remote MAC address information processing and brushing. Finally, the software function is tested on the actual equipment. The test results show that the MAC address information of the local equipment is notified to the remote equipment, and the MAC address information forwarding table of the local equipment is established, which meets the expected MAC address notification requirement.
