OPNET中支持Flow Label的网络模型设计与实现

Design and Implementation of Flow Label Supported Network Module in OPNET

Flow Label是在IPv6报头中新增的一个20比特的域,专为实时流提供有别于尽力而为流的服务,从而提供更好的QoS管理功能。仿真是研究网络模型及应用的重要手段,基于有限的关于Flow Label应用机制的研究,构建支持FlowLabel的仿真模型对Flow Label的研究与推广具有重要的意义。主要介绍了OPNET中支持Flow Label与QoS映射的客户端与网关模型的设计与实现。

Flow label is a 20-bit field in IPv6＇ s base header. It is designed particularly to provide better service than best effort service model, which will enable better QoS manageraent functions. Simulation is one important mechanism to evaluate the performance of network models and applications. It is of great significance to design flow label based simulation module for the research and promotion of flow label, especially with limited research on the application of flow label so far. A network module in OPNET which supports the Flow Label and QoS class mapping was proposed and implemented.
