BGP-4 is the routing protocol which holds the Internet together. Additionally and in the absence of a better solution, it is being used for traffic engineering purposes. In the absence of standardised procedures, each autonomous system in the Internet implements traffic engineering based on non-collaborative goals and using trial and error techniques. This paper analyses trial and error traffic engineering...
This work presents a dependable SIP overlay network for the usage in mobile ad hoc wireless networks focusing the availability of registrar and location services in combination with a reduced message transmission overhead regarding amount and size. In addition we enable a SIP presentity service which offers subscriber presentity state information to others. We show the performance of our approach...
Due to architectural similarities, routing protocols designed for ad hoc networks have been applied to wireless mesh networks (WMNs). However, such routing protocols do not scale well in WMNs, requiring considerable research efforts for enhancing them. In order to scale up WMNs, this paper introduces a three-layered routing architecture designed for infrastructure WMNs, which explores a hybrid routing...
Pakistan Internet Exchange (PIE) is the largest Internet Exchange Point (IXP) in Pakistan operated and maintained by Pakistan Telecom. PIE serves almost all categories of IP users like ISPs, Educational Institutions, DNOPS, VOIP Operators, Cable Operators and Institutions with multiple services like Internet Access, DSL, MPLS-VPNs, VoIP, IPTV and VoD. PIE has 3 main nodes and 42 remote nodes with...
A mobile ad hoc network (MANET) is a kind of self-configuring ad hoc network of mobile routers connected by wireless links. Vehicular Ad Hoc Networks (VANETs) are MANETs used for communication among vehicles, and between vehicles and roadside equipment. In order to create a new routing protocol applied to car-to-car networks, we define some parameters to evaluate the efficiency of some of the existing...
