A Fragmentation Scheme for Multimedia Traffic in Active Networks

Multimedia data are usually very large in size. Fragmentation of multimedia data unit is inevitable when they are transmitted through networks. Active networks are becoming popular and the active technologies are being applied to various interesting problems. When applying active technologies on multimedia data, however, the problem of fragmenting large packets still exists. Furthermore, new issues emerge when active capsules are fragmented. In this paper, we propose a new fragmentation scheme which addresses the unique need of active networks and utilizes the special properties of active networks. We propose an algorithm to fragment the data at the transport layer which can minimize the overhead. Preliminary experimental result shows that the scheme works well under realistic scenario, with less than 5 % of overhead
