基于SCTP的异构网垂直切换研究
摘要
本文首先对异构网中的移动性管理进行介绍
对本文采用的传输层协议SCTP协议进行详细分析
在现有的基于SCTP协议的垂直切换方案上进行考虑
提出了一种基于SCTP协议的软切换方案
通过ns2仿真可以知道:当切换到带宽大的网络时分组丢失将比切换到带宽小的网络分组丢失严重
同时由于传输层协议的慢启动
通信开始和切换过程的传输速率很低。
Abstract
Firstly the heterogeneous network mobility management is carried on
and the SCTP protocol is particularly introduced. Based on the existing plan
we proposed a newplan named SCTP soft handover. The simulation result shows that when handover to the network with bigger bandwidth
the packets dropped is more than that when handover to the network with smaller bandwidth. Besides
at the beginning and the handover the trans-mission speed becomes to be very low.
