— Multi-Protocol Label Switching is useful in managing multimedia traffic when some links are too congested; MPLS Traffic Engineering is a growing implementation in today's service provider networks. In This paper we propose an improvement of MPLS-TE called EMPLS-TE, it is based on a modification of operation of Forwarding Equivalence Class (FEC) in order(More)
IPv6 is a next-generation Internet layer protocol designed by the IETF (Internet Engineering Task Force) to solve the problem of IP address depletion under the current Internet layer protocol. It has been developed to replace the current Internet Protocol version 4 (IPv4). Various operating systems support IPv6 protocol stacks and network infrastructures(More)
Consuming less energy to evenly distribute the traffic load defines a major task for efficient routing protocols in Mobile Ad hoc Networks (MANets). Indeed, this process can avoid congestion, increases the network lifetime and maintains consequently green communications. In order to evaluate this capability, we introduce in this paper a new performance(More)
The QoS routing generates a significant number of control messages (overhead), which are necessary for the discovery and maintenance of routes. Indeed, the nodes must establish a mechanism to store and update the link-state in a mobile environment. This mobility in ad-hoc environment makes maintaining the link-state very difficult and costly. In addition to(More)
This paper deals with the LTE downlink transmission scheme, from the base station to the terminal (the mobile phone), which is based on multicarrier modulation: OFDM (Orthogonal Frequency Division Multiplexing). LTE also supports the use of multiple antennas at both the base station and the terminal to improve communication performance: Multiple Input --(More)

In this paper we examine the problem of evaluating the performance of TCP connections in a wide area network. Our approach combines analytical and simulation methods. Our model is represented by two finite buffer queues which are shared by two connections. One being the reference TCP connection and the other representing the exogenous traffic (in simulation(More)
