This scheme gets over several severe shortcomings in other schemes , just like poor scalability in network design , low usage in network bandwidth utilization , etc . to implement this scheme , we designed hardware platform with powerful network processor ixp1200 本文在方案的实现方面,以功能强大、性能稳定、方便灵活的网络处理器ixp1200为处理核心,结合多业务传送平台设备整机的具体要求,设计、构建了城域以太网处理单元的硬件平台。
This paper begins with analyzing current metro transport network . combined with ethernet work technologies , an innovative scheme has been proposed to solve transporting packet - service on metro transport network . in this scheme , the key technology is using stackable vlan to establish metro ethernet evc , and using " self - limited " protocols to manage layered metro ethernet network 方案中采用了可堆叠式vlan ( stackablevlan )技术来建立城域以太网evc连接,提出并采用了“自限”的概念,改造了用于以太交换网络的传统生成树算法和传统gvrp协议,实现了网络设备的分层、分自治域管理。
