摘要

在本文中，我们提出了一个基于代理的系统(MOWSER)来支持移动客户端在无线网络上的网页浏览。Mowser是移动主机和web服务器之间的代理代理，它根据用户设置的QoS参数，对上下游流量的数据进行主动转码，将web信息呈现给移动用户。活动转码被定义为在现场修改HTTP流，并且对用户完全透明。此外，我们的系统不会对移动用户提出任何额外的要求。这是对其他基于代理的系统的改进，这些系统只在下游对图像进行转码，并且大多数是不可配置的。虽然是为移动用户开发的，但这样的系统实际上可以在任何低带宽场景中使用。

An active transcoding proxy to support mobile web access

In this paper, we present a proxy based system (MOWSER) to support web browsing from mobile clients over wireless networks. Mowser is a proxy agent between the mobile host and the web server, which performs active transcoding of data on both upstream and downstream traffic to present web information to the mobile user according to the QoS parameters set by the user. Active transcoding is defined as modifying the HTTP stream in situ, and it is entirely transparent to the user. Further, our system does not pose any additional requirements on the mobile user. This is an improvement over other proxy based systems, which only transcode images on the downstream and are mostly not configurable. While developed for mobile users, such a system can actually be useful in any low bandwidth scenario.
