Theory and experiments show that as the per-flow product of bandwidth and latency increases, TCP becomes inefficient and prone to instability, regardless of the queuing scheme. This failing becomes increasingly important as the Internet evolves to incorporate very high-bandwidth optical links and more large-delay satellite links.To address this problem, we(More)
We consider power and server allocation in a multibeam satellite downlink which transmits data to <i>N</i> different ground locations over <i>N</i> time-varying channels. Packets destined for each ground location are stored in separate queues and the server rate for each queue <i>i</i> depends on the power <i>p<sub>i</sub></i> (<i>t</i>) allocated to that(More)
Wireless vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication holds great promise for significantly reducing the human and financial costs of vehicle collisions. A common characteristic of this communication is the broadcast of a device's core state information at regular intervals (e.g. a vehicle's speed and location, or a traffic(More)
Rate-based feedback congestion control has been proposed as a form of traffic management for available bit rate traffic in ATM networks. This paper discusses applying linear control theory to these algorithms. A congestion control scheme for simple networks is designed and analyzed using the tools of classical control theory. This allows insight into the(More)
