基于负载均衡的MAP选择方案的研究

RESEARCH ON MAP SELECTION SCHEME BASED ON LOAD BALANCING

针对层次移动IPv6中,移动节点(MN)选择移动锚点(MAP)没有考虑负载的问题,提出一种基于负载均衡的MAP选择方案。在该方案中,当路径中路由器的负载度量值大于所设置的阈值时,路由器就会丢弃数据分组以减小网络内的拥塞。当MN进入新网络时,根据设置的实时度量值来选择负载小的路径,然后向该路径的源MAP进行注册,使MN可以根据路径负载的不同来选择不同层的MAP,避免某些MAP成为整个网络的瓶颈,均衡整个网络的MAP负载。模拟实验结果表明,该方案能使网络中的MAP负载更加均衡。

To deal with the problem that Mobile Node（MN） do not take load problem into account when it choose Mobile Anchor Point（MAP）,an MAP selection scheme is proposed based on load balancing. In this scheme,when the load of the router in the path is greater than the threshold value,the data packet will be discarded to reduce the congestion in the network. When MN enters a new network,it will select the route with the smallest load according to the real-time measurement,and then register the source MAP. Thus,MN will select MAP in different layers according to the load of route,avoiding some MAP become the bottleneck of the entire network and balancing the MAP load in the whole network. The result of the simulation experiment shows that the new scheme can make the load of MAP in the network more balanced.
