网络互连是当今计算机网络发展的一重要课题。本文着重探讨了一种基于环树形信关网络结构的互连网络方案。信关网络中以信关资源预申请法避免拥挤发生,以虚电路技术的改进方法——连结报文法传输分组,以分段路由选择法进行路由判断。经过理论及模拟分析,认为这种方案具有良好的网络功能与性能,较适合于大规模网络互连。
Network interconnection is an important issue in the development of computer networks today. This article focuses on an interconnection network scheme based on a ring tree shaped gateway network structure. In the credit network, pre-application of credit resources is used to avoid congestion. In the improved method of virtual circuit technology, the packet transmission method is used to transfer packets, and the routing is determined by the piecewise routing method. After theoretical and simulation analysis, it is considered that this scheme has good network function and performance, which is more suitable for large-scale network interconnection.
