Caching is an efficient way to reduce network traffic congestion during peak hours by storing some content at the user's local cache memory without knowledge of later demands. For shared-link caching model, Maddah-Ali and Niesen (MAN) proposed a two-phase (placement delivery) coded strategy, which order optimal within constant factor. However, in MAN scheme, each user can obtain information abo...

In ATM networks, Virtual Path Connections (VPCs) are not only a device for bundling Virtual Circuit Connections (VCCs), but they serve as an intermediate resource management layer wherein tradeoos between cost, complexity, and eeciency are likely to be made on a slower time scale than connection holding times. In this paper we consider bundling multicast connections on VP trees. In particular, ...

he Applied Physics Laboratory, in its role as Technical Direction Agent for several Navy radar development programs, applies a coherent data collection and analysis methodology when evaluating system performance. Programs that have benefited from this approach include the Mark 92 Modification 6 (MK 92 MOD 6) fire control system, the Phalanx close-in weapon system, and the AN/SPS-48E surveillanc...
