Internet routing protocols, such as Open Shortest Path First (OSPF), compute a shortest path tree from each node to other nodes in the network, using link-state information. Such protocols do not consider the queueing situation at a given node. An alternate path of higher cost may be more convenient to use than the optimum path when a long queue is present at the node. This paper proposes a new...

Explicit routing and the pre-allocation of network resources are essential to achieve absolute end-to-end QoS guarantees in networks. MPLS (MultProtocol Label Switching) provides a good platform to implement explicit routing and also supports pre-establishment of multiple explicit routes for a source-destination pair. We show that MPLS can achieve reliable explicit routing, by deploying maximal...

In this paper, the network behavior of a routing algorithm for mobile ad hoc networks is investigated. Extensive simulations are performed using ns-2 in a variety of mobility scenarios and offered load regimes. In the literature, performance metrics (goodput, delay and path length) are often obtained through ensemble averaging of many flows. Here we advocate an alternate graphical interpretatio...

Routing in Mobile Ad hoc Network (MANET) is the challenging issue because of their dynamic topology. The multipath routing are definitely providing the reliable communication and mechanism of alternate path if first break but effective load balancing has a demanding task in MANET due to their dynamic and un-predictable nature. For effective working of MANET multiple routing backbones are identi...

In hybrid mobile ad hoc network (MANET), the mobility of the ad hoc nodes can cause route failures and necessitates the new route discovery. Also the mobility can result in delay and overhead. In this paper, we propose a multi-criteria gateway selection and multipath routing protocol for hybrid MANET that considers mobility metric as one of the criterion for the selecting the gateway. For gatew...

The effect of antimycin A on the respiration of fresh potato (Solanum tuberosum var. Russet Burbank) slices has been determined in the presence and absence of m-chlorobenzhydroxamic acid (CLAM). Two antimycin-binding sites are indicated. At low concentrations antimycin alone inhibits respiration only slightly. When CLAM and low antimycin are added together, respiration is sharply inhibited, as ...

The paper presents approaches for fault tolerance and load balancing in QoS provisioning using multiple alternate paths The pro posed multiple QoS path computation algorithm searches for maximally disjoint i e minimally overlapped multiple paths such that the im pact of link node failures becomes signi cantly reduced and the use of multiple paths renders QoS services more robust in unreliable n...

This study deals with the formulation of an effective and efficient algorithm for load balancing in WDM networks. Here we develop a Load Balancing algorithm for IPlike Routing. The considered networks are based on a routing protocol where the next hop at a given node depends only on the destination of the communication. The aim of this work is to consider the applicability of this approach in t...
