新型以太网冲突仲裁算法的设计与仿真

A New Algorithm of Collision Arbitration Based on Ethernet

以太网凭借其成本低、速度高、协议简洁以及良好的轻载性能 ,成为目前最为流行的网络技术之一。针对标准以太网介质访问控制协议存在的捕获效应和重载时网络性能差的缺点 ,该文提出了一种新的冲突仲裁算法 ,并对其进行建模仿真。仿真结果表明 ,与TBEB算法相比 ,该算法不但解决了捕获效应 。

Depending on its low cost,high speed,simple protocol and good performance of light load , Ethernet has become a very popular technology in the world. On the basis of the limitation of Ethernet's Media Access Control protocol such as the capture effect and the poor performance of heavy load, a new kind of collision arbitration algorithm is proposed, then simulated in computer. By comparing it with TBEB algorithm, the simulation result shows that the new algorithm not only solved the capture effect successfully, but also improved Ethernet's real-time property and performance of heavy load.
