Content adaptation on LANE active network platform

As the number of different content types in the Internet is increasing as well as the number of terminal types, the heterogeneity of both content and terminals has become a problem. A common solution is to convert the content to a suitable format for terminal application either in the server or in the client. More sophisticated solution is to use static proxy-servers in order to adapt the content, in real time and inconspicuously. However, if the terminal is a mobile device, the static proxy-servers are unable to accommodate to changing characteristics of network (i.e. topology, bandwidth, delays etc). Active networking enables the proxy-style adaptation but also meets the special requirements of mobile devices. At VTT, an active network (AN) system called LANE was developed. The LANE system introduces content converting active application. With LANE based implementations, it is possible to reach more efficiently located and more transparent adaptation compared to the conventional static proxy servers. Currently LANE introduces a demonstration, in which the Microsoft Word document is converted into other formats.
