集成多路径数据传输（IMPDT）的概念被引入到有效地传输大规模的数据，如果多个异构网络是可用的，但没有一个有足够的性能所请求的任务。IMPDT集成异构网络不仅用于带宽聚合，而且用于在稳定但低数据速率的网络路径上提供可持续的控制信息交换，以不同的方式与不同网络路径上的数据传输分开处理。在本文中，IMPDT的原型实现的设计进行了讨论，特别是侧重于重传，这是通过现场实验，使用不同类型的无线通信系统进行评估。然后，通过集成HTTP协议和IMPDT方案，讨论了Web访问系统的原型实现的设计，作为一个交互式应用程序在多个挑战的网络，这意味着我们提出的方案具有潜在的广泛适用性。
A concept of integrating multi-path data transfer (IMPDT) is introduced to efficiently transfer a large-sized data if multiple heterogeneous networks are available but none of them has sufficient performance for the requested task. IMPDT integrates heterogeneous networks not simply for bandwidth aggregation but also for providing sustainable control information exchange on a stable but low data rate network path, being handled separately from data transmission on different network paths in different ways. In the present paper, the design of a prototype implementation of IMPDT is discussed especially focusing on retransmission, which is evaluated by field experiments using different types of wireless communication systems. Then the design of a prototype implementation of web access system is discussed as an interactive application over multiple challenged networks by integrating the HTTP protocol and the IMPDT scheme, which implies a potentially wide applicability of our proposed scheme.
