基于Petri网IP网QoS策略控制方法建模

Modeling of QoS Maneuver Controlling Process Based On Petri Net

研究网络中多种业务对QoS要求日益提高与网络资源矛盾愈发突出导致的QoS高效控制策略机制模型建立的问题。针对目前QoS策略控制系统运行效率相对较低的现状,提出了一种基于Petri网的控制策略机制模型。该模型具有良好的可移植性,将其应用到IP网QoS策略控制的建模中,可以建立一种快速、高效的QoS控制策略系统模型。经过数学推导和Petri网的机制理论验证得出,该模型是一种高效的QoS策略控制系统模型,其准确清晰,直观易懂,对IP网的QoS策略控制机制建立有实际指导意义。

Researching the problem of building QoS controlling mechanism and reassemble the resource effectively which are resulted from the confliction of the shortage of Internet resource and more QoS needs from different kind of services..Aim at the problem of low efficiency of QoS Policy Control System,it is particularly essential to establish a more scientific method of economic processes based on the system modeling,simulation,analysis and optimization. In this article,QoS maneuver controlling process is modeled using Petri Net.The model is accurate,clear and easy to be understood.Through mathematical derivation and the Petri net verification regime theory,the conclusion is obtained that the model is a highly efficient model for QoS Policy Control System,its precise,clear,intuitive and understandable, and has practical application value for IP Network QoS Policy Control Modeling.
