目前，人们正在为 IPv6 移动网络指定分布式移动管理（DMM）进行各种努力。 DMM有望消除当前IPv6移动协议的限制并应对移动数据流量的快速增长。在当前的DMM方法中，移动性锚定分布在接入路由器级别，并且移动节点动态地改变新会话的移动性锚定。尽管此类方法避免了任何网络瓶颈并在大多数情况下允许最佳路由，但由于移动节点没有永久 IPv6 地址，因此它们缺乏可达性支持。在本文中，我们考虑 DMM 方法之一——动态移动锚定，并研究使用会话发起协议 (SIP) 来提供可达性支持。定义不同的基于 SIP 的位置更新模式后，我们考虑与每个网络实体的处理负载相关的新性能指标，进行比较成本分析。我们考虑位置服务器上的位置更新负载以及移动锚点上的上下文、信令和隧道负载。我们研究了几种场景中的不同模式，允许移动网络运营商根据其架构采用首选模式。
Currently, various efforts are being performed on specifying distributed mobility management (DMM) for IPv6 mobile networks. DMM is expected to eliminate the limitations of the current IPv6 mobility protocols and to cope with the rapid increase in mobile data traffic. In current DMM approaches, the mobility anchoring is distributed at the access router level and the mobile node changes dynamically the mobility anchor for new sessions. Although such approaches avoid any network bottleneck and allow optimal routing in most cases, they lack reachability support since the mobile node has no permanent IPv6 address. In this paper, we consider one of the DMM approaches, dynamic mobility anchoring, and study the usage of session initiation protocol (SIP) for providing reachability support. After defining different SIP-based location update modes, we carry out a comparative cost analysis considering new performance metrics related to the processing loads at each network entity. We consider the location update loads on the location server as well as the context, signaling, and tunneling loads on a mobility anchor. We investigate the different modes in several scenarios, allowing the mobile network operator to adopt the preferred mode depending on their architecture.
