Policy based management is being adopted widely for different domains like QoS, security and VPNs in order to allow new services and facilitate network management. Also, the interface to the network device and the information models required for specifying policies are either standardized or being standardized in IETF and DMTF. This paper reports the(More)
—In future wireless networks, different traffic classes will exhibit a large variety of characteristics and QoS requirements, such as transmission rate, maximum tolerable bit error rate and timeout specifications. However, currently there is no standard way of guaranteeing QoS in wireless access networks like Wireless LAN based on IEEE 802.11. In this(More)
The inevitability of pain during infancy and its potential for destructive impact impose a burden on caregiving adults. An armamentarium of effective pharmacological, behavioral and environmental interventions is available if pain were recognized and accurately assessed. Infants have limited behavioral repertoires that make identification of specific needs(More)
Asynchronous Transfer Mode (ATM) is widely accepted as the transfer mode for Broadband Integrated Services Digital Networks. Since ATM networks provide connection-oriented services, signalling is an essential component of these networks. The performance of the signalling system is crucial in determining the scalability of the network. Call performance(More)
As communication networks provide newer services, signaling is becoming more and more compute intensive compared to present day networks. It is known that under overload conditions, the call throughput (goodput) and the network revenue drops to zero even when transport resources are available. A distributed overload control algorithm for delay-bounded call(More)
In order to accommodate the new generation of Internet applications, routers need to be designed to support QoS, policy based management, and mobility. This paper presents an architecture for the control plane of a software router that integrates signaling protocols and control mechanisms for QoS, policy based management, and mobile IP. The architecture has(More)
