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.

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。
