When a set of mpls nodes have information in their libs related to the same destination , a label switched path ( lsp ) has been created 當(dāng)一組mpls節(jié)點在它們的lib中擁有了與同一目的地有關(guān)的信息時,就建立起一個標(biāo)簽交換通道( lsp ) 。
The most important advantage that mpls can supply in the research on traffic engineering is that it can route ip packets to an lsp ( label switched paths ) 在流量工程的研究中, mpls所提供的最大的優(yōu)點是能夠?qū)p分組路由到一條標(biāo)簽交換路徑lsp ( labelswitchedpaths )上。
According to the mentioned theories and its specifications from national standards , mcp ( management and control processor ) software is designed in this paper , which based on former version running on available optical node devices , such as mstp and oadm / oxc . it can perform the basic functions defined in ason control panel . it adds the route , signaling and lmp basic function modules to complete building , deleting or refreshing the sc ’ s ( switched connect ) lsp ( label switch path ) 本設(shè)計在嵌入式實時多任務(wù)操作系統(tǒng)( rtos )基礎(chǔ)上對現(xiàn)有的光網(wǎng)絡(luò)節(jié)點設(shè)備( mstp和oadm / oxc設(shè)備)的網(wǎng)元管理控制器( mcp )的軟件進(jìn)行擴展,增加路由、信令和鏈路資源管理等功能模塊,實現(xiàn)了ason控制平面的基本功能,及波長路由光網(wǎng)絡(luò)中交換式連接的波長lsp的建立、刪除和維護(hù)等操作。
