The aim is to deliver video to heterogeneous clients using only a single video stream. This is possible using a layered wavelet-based codec that allows a video stream to be encoded and divided, and is then distributed using several multicast channels. A layered multicast method of delivery allows each client to control the amount of video information it receives, and hence the video quality, without the server having to transcode or modify the video stream. However, because there are devices that cannot receive multicast data, e.g., handheld devices or PDAs, a proxy gateway was developed to receive the multicast stream and retransmit them in a unicast manner The proxy gateway, designed primarily to support the low-powered handheld devices, also performs buffering and other actions that may require amounts of memory that handheld devices do not have. This complete system is now in its final stage of development and the performance of the proxy gateway and unicast handheld-based client have been tested.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

We consider a scenario in which a large pool of customers from one or more number of remote sites on this network demand a multimedia program situated on a site for viewing at different time instants. This process of distribution of the requested program involves communication costs and caching costs of the program before it is delivered to the users at their desired viewing times. We configure the MANs as a fully-connected topology and show that a single copy of the requested document is sufficient to serve all the user requests in an optimal manner, for the case of high speed networks. Using this strategy, the personal service agents (PSAs) will decide when, where, and for how long the requested programs must be cached to obtain an optimal solution.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).

The scenario we consider is where TCP packets traverse a wired network to a base station, and thence over a single wireless hop to a stationary receiver. Unlike many previous studies, which rely on simulation, we develop an analytical model for calculating TCP throughput; unlike all previous analytical studies, we do not ignore the possibility of acknowledgement packets (ACKs) being lost on the reverse link from the wireless receiver to the base station. The analytical model captures the performance of four common TCP algorithms: OldTahoe, Tahoe, NewReno and Sack. We find that, for the scenarios studied, a moderate number of link-level retransmissions can significantly improve the throughput of TCP and its resilience to packet losses on the forward and reverse links; increasing the number of retransmissions further has relatively little benefit. We also show that ACK losses cannot be ignored unless the number of retransmissions permitted is high or errors on the reverse link are infrequent. Of the TCP algorithms studied, we find that Sack has the best performance, closely followed by NewReno; the performance of OldTahoe is very poor. We end with suggestions for further work.","PeriodicalId":191244,"journal":{"name":"Proceedings IEEE International Conference on Networks 2000 (ICON 2000).
