We consider data networks in which real-time/near real-time applications require not only successful transmission of packets from source to destination, but also specific end-to-end delay bounds, such as voice over IP. Although there is a well-developed general theory for control of best-effort packet traffic in data networks (elastic traffic), little is known about decentralized control mechanisms...
An emerging communication service with significant potential is delivery of personalized content. Such a service typically is provided through either live or time-shifted program multicast. While the former requires adequate bandwidth for a combination of unicast, multicast or broadcast, the latter typically leverages caching. Both modes of distribution have hard resource constraints. Determination...
In this paper we study the problem of jointly performing scheduling and congestion control in mobile ad-hoc networks so that network queues remain bounded and the resulting flow rates satisfy an associated network utility maximization problem. In recent years a number of papers have presented theoretical solutions to this problem that are based on combining differential-backlog scheduling algorithms...
We establish analytical descriptions of extra capacity for shared mesh restoration of single link failures in mesh networks. These descriptions provide insight into the underlying dependencies allowing fast computation of the tradeoffs among survivability strategies.
