摘要:
 
随着网络技术的发展,多宿主主机越来越普及.多路径并行传输可以充分利用多宿主主机的优势,不仅可以最大限度利用带宽,提高数据吞吐量,而且可以提高容错率,在一条路径出现故障时,迅速切换到其他路径进行数据传输.文中基于多路径传输以及动态地址变换的特点,引入了连接标识进行通信.通过建立连接标识与接入标识之间的映射,代替传统网络依靠五元组进行连接的管理,以更好地适应多路径传输.简述了如何基于流控传输协议实现多路径传输以及动态地址变换,并定义了连接标识的生成方法.给出了一种在本地建立连接标识与接入标识映射的方法,并阐述了基于连接标识通信的优势:更加适应多路径传输;更好地增加传输安全性;更好地对连接进行管理等.对不同带宽以及时延下的吞吐量进行了测试,并与传统传输协议进行了性能对比.使用连接标识进行多路径传输可以提升性能,更好地支持动态地址变换,达到身份与位置分离的目的.
Abstract:
 With the development of network technology,multi-homing host is becoming more and more popular. Concurrent multipath transfer can take full advantage of it,which not only can maximize the use of bandwidth and improve data throughput,but also can im-prove the fault tolerance. When a path occurs failure,it can quickly switch to other paths for data transmission. Based on the characteristics of multipath transmission and dynamic address translation,the connection identifier is introduced for communication. Instead of the five-tuple,establishing the mapping between the connection identifier and the address identifier can better adapt to multi-path transmission. It describes how to implement multipath transmission and dynamic address translation based on stream control transmission protocol,and de-fines the generation method of connection identifier. A method is put forward to establish the connection identifier and access identifier mapping locally and the advantages of communication on the basis of connection identifier are also described,including more adaptive to multi-path transmission, better enhancement of transmission security, and management of connections. The throughput under different bandwidth and delay is tested,and the performance is compared with the traditional transmission protocol. Multi-path transmission using the connection identifier can improve performance and better support dynamic address translation,achieving the purpose of identity and location separation.
