| 摘 要： | 提出了一种移动IPv6端到端的DiffServ上下文转移框架，采用COPS-SLS协议作为DiffServ在移动环境下的信令机制来实现端到端的域间SLS动态磋商，使用端到端的上下文转移方法来重建DiffServ上下文可以避免重新发起COPS-SLS信令，并且端到端的DiffServ上下文仅在新增加路径中的QB间进行转移。该方法能减少切换时的服务中断，当MN切换时，实时应用能迅速得到与切换前相同的转发处理。

| Abstract: | This paper proposes a framework for end-to-end DiffServ context transfer in mobile IPv6, The COPS-SLS protocol is used as a signal mechanism to achieve end to-end inter-domain SLS dynamic negotiation for DiffServ in mobile environments. By using the context transfer to re-establish DiffServ context, it can avoid re-initiating COPS-SLS signaling from scratch, and the end-to-end DiffServ context only transfers to the new added QBs along new path after the MN performs handover. Hence, the scheme can minimize the handover service disruption, and enable real time session to promptly get the same forward process during the MN performs handover. |
