中文摘要：

在简述现存网络架构的技术弱点后,提出了微通信元系统架构的思想,微通信元体系结构对不同服务类型的数据构建不同的虚电路进行传输。针对这种数据通信策略,提出了一种基于反馈信息位的拥塞控制机制,该机制根据来自路由节点的反馈信息调整一个虚电路发送端的发送速率,以实现拥塞控制。NS仿真表明,此机制能有效提高网络的吞吐量,改善网络的性能。

英文摘要：

After analyzing the deficiency of contemporary network architecture, the idea and concept of micro-communication element system（MCES） were introduced, MCES designs different virtual circuit （VC） for different types of data. In order to resolve congestion problem and increase good throughput for MCES, a congestion feedback signals based mechanism which uses routing feedback information to adjust the sending rate was proposed. NS simulation results show that this new scheme can significantly improve the performance of network.
