乘坐汽车、公共汽车或火车旅行的移动用户通常会在途中遇到不同的连接特性，包括不可预测的（丢失）网络访问、数据速率的变化等。简而言之，它们在一个不太适合许多Internet应用程序的具有挑战性的网络环境中运行。虽然已经开发了不同的方法来专门缓解（短期）断开，同时至少部分地保留此类应用程序的端到端概念，但容忍延迟网络（DTN）采用了一种不同的方法，它完全依赖于异步通信。虽然这很适合移动用户连接，但特别是交互式应用程序（如web访问）由于缺乏同步端到端交互而受到影响。在本文中，我们提出了运行HTTP-over-DTN的协议机制以及用于增量部署的系统架构，并报告了使用我们的原型实现执行的测量结果。
Mobile users traveling by car, bus, or train usually experience varying connectivity characteristics while they are on their way, including unpredictable (loss of) network access, changes in a data rate, and the like. In short, they operate in a challenged networking environment that is not well suited for many Internet applications. While different approaches have been developed to specifically mitigate (short-term) disconnections while at least partly preserving the end-to-end notion of such applications, Delay-tolerant Networking (DTN) takes a different approach by relying exclusively on asynchronous communications. While this fits well with the mobile user connectivity, particularly interactive applications (such as web access) are affected by the lack of synchronous endto-end interaction. In this paper, we present protocol mechanisms for running HTTP-over-DTN as well as a system architecture for incremental deployment, and we report on findings from measurements performed with our prototype implementation.
