MPLS網(wǎng)絡主動式流量和擁塞控制機制及性能分析

An active traffic and congestion control mechanism in MPLS

  • 摘要: MPLS是具有大帶寬一時延遲的網(wǎng)絡，用傳統(tǒng)的TCP解決MPLS擁塞問題顯得十分困難，該文結合MPLS的網(wǎng)絡特點，提出了一種適合MPLS網(wǎng)絡的主動式流量和擁塞控制機制，在網(wǎng)絡邊緣節(jié)點引入擁塞反饋處理，對實驗模型進行了性能仿真分析，實驗證明，與傳統(tǒng)的TCP協(xié)議相比，該機制將流量和擁塞控制從用戶端點擴展到MPLS邊緣路由器，能夠更及時地檢測和控制網(wǎng)絡擁塞，縮短了控制時延，可以進行較精確的流量調(diào)節(jié)，實現(xiàn)了提高吞吐量和改善緩沖區(qū)利用率的目的。
    Abstract: Bandwidth-delay product in MPLS is so high that TCP protocols hardly solve the congestion in MPLS. This paper proposes an Active Traffic and Congestion Control (ATCC) mechanism in MPLS and its model, which utilities the characters of MPLS. MPLS ATCC moves the endpoint congestion control algorithms into the network. The comparison with traditional TCP shows that ATCC can find and control the congestion in time, reduce the round-trip delay, and edit the ingress traffic. So MPLS ATCC improves the total throughput and the utility of buffer.
