摘要： 在移动IPv6的基础上设计并实现了一种面向流的切换协议。该协议增加了2个消息(流绑定更新、流绑定应答消息)和流绑定更新列表。系统通过修改Linux内核网络部分的数据处理流程和数据结构，实现了移动切换过程中数据流灵活的重定向功能，为上层的智能切换策略提供更多功能。通过实验仿真能够看出采用流切换的方式，可以提高传输效率，更有效地利用网络资源。

Abstract: This paper designs and implements a Per-flow handover protocol based on mobile IPv6. It adds two messages(flow binding update, flow binding acknowledgement) and a flow binding list to mobile IPv6, and implements flexible data flow redirection by modifying Linux network kernel modules. The protocol provides more functions for intelligent handover policies of high layers. The experiments demonstrate that the Per-flow handover improves the performance of transmission and uses the network resource more efficiently.

Key words: wireless heterogeneous network, mobile IPv6, vertical handover, Per-flow handover protocol
