【摘要】：分段路由(segment routing,SR)是近幾年IETF提出的一種路由機(jī)制,其目的是使IP/MPLS網(wǎng)絡(luò)面向服務(wù)并且更高效。SR減少現(xiàn)有MPLS網(wǎng)絡(luò)控制平面復(fù)雜的協(xié)議(LDP/RSVP-TE),并實現(xiàn)流量工程等機(jī)制。與基于RSVP的顯式路徑中隧道中間節(jié)點(diǎn)維護(hù)報文流的狀態(tài)不同,基于SR的顯式路徑只在入口邊界路由器中維護(hù)報文流的狀態(tài),從而提高了網(wǎng)絡(luò)的可擴(kuò)展性,因此SR對于下一代互聯(lián)網(wǎng)具有重要的研究意義。對SR的實現(xiàn)機(jī)制進(jìn)行了研究,利用軟件路由平臺Click,對基于PCE架構(gòu)的SR控制平面子系統(tǒng)和基于MPLS的SR數(shù)據(jù)平面子系統(tǒng)的各個模塊進(jìn)行實現(xiàn),并在實際中進(jìn)行部署,以驗證SR軟件路由器的可行性。
[Abstract]:Segmented routing (segment routing,SR) is a routing mechanism proposed by IETF in recent years, which aims to make IP/MPLS network service-oriented and more efficient. Sr reduces the existing MPLS network control plane complex protocol (LDP/RSVP-TE), and implements traffic engineering and other mechanisms. Different from the state of the tunnel intermediate node maintaining the message flow in the explicit path based on RSVP, the explicit path based on SR only maintains the state of the message flow in the entrance boundary router, thus improving the scalability of the network, so SR is of great significance for the next generation Internet. The implementation mechanism of SR is studied. Each module of SR control plane subsystem based on PCE architecture and SR data plane subsystem based on MPLS is implemented by using software routing platform Click, and deployed in practice to verify the feasibility of SR software router.
