【摘要】:針對(duì)域內(nèi)流量均衡問(wèn)題,提出了一種二維開(kāi)放式最短路徑優(yōu)先(OSPF)路由方案TOL。在控制層面,通過(guò)對(duì)傳統(tǒng)鏈路狀態(tài)通告(LSA)的擴(kuò)展,實(shí)現(xiàn)包括目的前綴和源前綴的二維路由信息的傳遞,路由器根據(jù)二維路由信息進(jìn)行計(jì)算,生成二維路由表項(xiàng)。在數(shù)據(jù)轉(zhuǎn)發(fā)層面,設(shè)計(jì)了一種基于傳統(tǒng)一維轉(zhuǎn)發(fā)表實(shí)現(xiàn)二維數(shù)據(jù)轉(zhuǎn)發(fā)的方案,這種轉(zhuǎn)發(fā)方案能夠有效解決引入源前綴造成的轉(zhuǎn)發(fā)表存儲(chǔ)空間增長(zhǎng)問(wèn)題,兼容傳統(tǒng)轉(zhuǎn)發(fā),為T(mén)OL提供保障。為了驗(yàn)證TOL的有效性和可行性,在商用路由器上實(shí)現(xiàn)了原型系統(tǒng),測(cè)試和實(shí)驗(yàn)結(jié)果表明,TOL方案能夠在傳統(tǒng)IP網(wǎng)絡(luò)結(jié)構(gòu)和協(xié)議的基礎(chǔ)上,有效實(shí)現(xiàn)流量均衡,減少鏈路擁塞,且不會(huì)帶來(lái)較大的額外負(fù)荷。
[Abstract]:In order to solve the problem of intra-domain traffic balance, a two-dimensional OSPF routing scheme named OSPF is proposed. At the control level, the traditional link state notification (LSA) is extended. To realize the transfer of two-dimensional routing information including destination prefix and source prefix, routers calculate according to two-dimensional routing information and generate two-dimensional routing table items. A 2D data forwarding scheme based on traditional one-dimensional forwarding table is designed. This forwarding scheme can effectively solve the problem of storage space growth caused by the introduction of source prefix, and is compatible with traditional forwarding. In order to verify the validity and feasibility of TOL, the prototype system is implemented on commercial routers. The test and experimental results show that the proposed scheme can effectively realize traffic balance on the basis of traditional IP network structure and protocol. Reduces link congestion and does not bring extra load.
