主动网技术及应用

主动网比传统网络具有更大的灵活性，它可以在分布式系统中更好地协调不同设备的工作，把计算所需的负荷和数据传输的负荷较合理地分担给不同设备，有效地避免单点故障，并能够缩短数据处理和数据传输的时延，提高数据的端到端(end-to-end)可达性，在主动网中，有望依照网络的当前状态，对路由器等交换设备的缓冲进行细致的管理、并对数据流所携带的信息进行归类和缓存，利用冗余路径进行数据传输，从而降低拥塞的概率和拥塞的程度，提高网络的当前性能和可预测性。

Active Networks and Applications

Active networks has more flexibility than traditional networks, and can be applied to cordination of various devices in a distributed system,distribution of computation and communication burden among different facilities,effective avoidance of single device failure, decreasing delay, and enhancing end-to-end reachability. With active networks technology, elegant management of buffer in router or swithing device become possible,data flow can be effectively classified and transfered using abundent route and it cas achieve lower congestion possibility, higher performance and more predictability.
