基于位置更新与数据转发分离的NEMO优化机制

Locate updating and packet forwarding separation based optimization mechanism for NEMO

针对移动网络(NEMO)应用在代理移动IPv6网络(PMIPv6)域中系统总开销较大并且中心锚点可能过载的问题,提出了一种基于位置更新与数据转发分离的移动网络优化机制。该机制引入专门负责位置信息管理的新实体,充分利用架构中各实体上的绑定缓存消息,优化信令流程,实现控制平面和数据平面的有效分离。性能分析结果表明,该方案降低了系统总开销,提升了系统可靠性。

To reduce total cost of NEMO in PMIPv6 domain and overload of management anchor, a locate updating and packet forwarding separation based location management mechanism for NEMO is proposed. With the help of a new entity sepecially de signed for location management and extended signaling messages in mobility management entities, signaling flow is optimized, ef fective separation of control lay and data lay is achieved. Analysis and simulation shows that proposed method reduces total cost and improves the system reliability.
