提出了一种用于处理适当数据链路接口之间的无缝切换的移动性管理方案。未来的移动环境将以多模式连接到互联网为特征，并基于多种因素进行动态切换。已经提出了许多技术来支持跨不同无线接入网络的主机移动性，并在网络体系结构的不同层中运行。我们主要关注的是恢复切换过程中丢失的分组并控制传输速度以实现高效通信的传输协议。在本文中，我们首先研究了与切换机制相关的各种延迟，并讨论了基于单个传输连接的现有技术的有限性能。然后，我们提出了一种新的移动性管理方案，该方案通过支持多连接的传输协议来解决性能受限的问题。我们将该方案的性能与现有技术进行了比较，证明了该方案取得了较好的性能。
A mobility management scheme for handling seamless handoffs between appropriate datalink interfaces is presented. The future mobile environment will be characterized by multimodal connectivity to the Internet with dynamic switching based on many factors. Many technologies have been proposed to support host mobility across diverse wireless access networks, and operate in various layers of the network architecture. Our major concern is the transport protocol that recovers packets lost during handoffs and controls transmission speed to achieve efficient communication. In this paper, we first examine the various latencies associated with the handoff mechanism, and discuss the limited performance of existing technologies based on a single transport connection. We then propose a new mobility management scheme that resolves the problems of limited performance by transport protocol supporting multiple connections. We compare the performance of the proposed scheme with existing technologies, and demonstrate that the proposed scheme achieves excellent goodput performance.
