【摘要】：提出了一種TCAM空間劃分和規(guī)則壓縮相結(jié)合的方法,使得OpenFlow網(wǎng)絡(luò)在支持實時更新的同時能采用小容量的TCAM芯片來存儲網(wǎng)絡(luò)中的規(guī)則.所提方法將TCAM芯片空間劃分為實時更新區(qū)和壓縮存儲區(qū),實時更新區(qū)處在TCAM芯片的前部,用于存放中央控制器發(fā)送過來的實時更新規(guī)則.后臺服務(wù)器以一定的時間周期將TCAM芯片中的實時更新區(qū)的規(guī)則以及壓縮存儲區(qū)中的規(guī)則進行壓縮,并將壓縮后的規(guī)則存入TCAM的壓縮區(qū),保持實時更新區(qū)具有空間接收實時更新規(guī)則.分析了區(qū)間劃分的比率問題,并利用ClassBench工具產(chǎn)生原始規(guī)則集進行了仿真實驗,實驗結(jié)果驗證了本文方法的有效性.
[Abstract]:In this paper, a method of combining TCAM space partition with rule compression is proposed, which enables OpenFlow network to store the rules in the network by using a small TCAM chip while supporting real-time updating. The proposed method divides the TCAM chip space into real-time updating area and compressed storage area. The real-time updating area is located in the front of the TCAM chip and is used to store the real-time updating rules transmitted from the central controller. The background server compresses the rules of the real-time update area and the compressed storage area in TCAM chip with a certain time cycle, and stores the compressed rules in the compressed area of TCAM. Keeping the real-time update area has space-receiving real-time update rules. The ratio problem of interval partition is analyzed and the simulation experiment is carried out using ClassBench tool to generate the original rule set. The experimental results show that the proposed method is effective.
