局域网服务器缓冲区容量的Petri网设计方法

Petri Net Design Method on Buffer of Local Area Network Server

本文在分析局域网服务器信息缓冲区、数据包接受和发送缓冲区的相互关系基础上提出一种新的局域网服务器缓冲区设计方法─—广义随机Ｐｅｔｒｉ网方法，并给出了局域网服务器信息缓冲区的广义随机Ｐｅｔｒｉ网模型。该设计方法理论完备、严谨实用，且不再局限于追求某一边界值（上限或下限），并且避免了排队理论处理多级服务的繁琐公式。最后本文用一例题说明了这种方法的应用。

A new design method that is called general stochastic Petri net on buffer of local area network server has been given by analyzing structure of the buffers and relation of packet transmitting and receiving. The general stochastic Petri net models for the buffers were deduced. Performances of the networks were discussed. This method has strict theory and is useful to the area of computer network analysis. It’s more useful to compare with queue theory and approach. The method is not limited to estimate upper bound value and lower bound value as which by using queue theory to do. An applied example is given to show the application of the new design method.
