Multiprotocol Label Switching (MPLS) is an Internet Engineering Task Force (IETF) specified framework that provides for the efficient designation, routing, forwarding and switching of traffic flows through the network. MPLS is a versatile solution to address the problems faced by present-day networks like speed, scalability, quality-of-service (QoS) management, and traffic engineering. MPLS carries...
One of the major challenges for next-generation mobile systems is to achieve efficient mobility management in next generation wireless networks. To track host mobility, Mobile IP setup a tunnel between the Home Agent and the Mobile Node. This paper proposes a new architecture called LinkWork Mobile MPLS which takes advantage of MPLS traffic engineering capability, to achieve fast-reroute when a mobile...
This paper investigates the performance of exponential/proportional fair (EXP/PF) and maximum-largest weighted delay first (M-LWDF) scheduling algorithms in the third generation partnership project long term evolution (3GPP LTE) providing packet-switched multimedia services. It, then, identifies a suitable packet scheduling algorithm on a basis of their performance evaluation. The performance evaluation...
Heavy-tailed behavior of WWW traffic has serious implications for the design and performance analysis of computer networks. This behavior gives rise to rare events which could be catastrophic for the QoS of an application. Thus, an accurate detection and quantification of the degree of thickness of a distribution is required. In this paper we detect and quantify the degree of tail-thickness for the...
Mobile ad hoc network is an autonomous system of mobile nodes characterized by wireless links. A major challenge lies in adapting multicast communication to environments where mobility is unlimited and failures are frequent. The multicasting concept deals with one to many data dissemination, many multicast routing algorithm have been proposed like ODMRP, CAMP, NTPMR and so on. In this paper we design...
