Routing in computer networks has played a special role in recent years. The cause of this is the role of routing in a performance of the networks. The quality of service and security is one of the most important challenges in routing due to lack of reliable methods. Routers use routing algorithms to find the best route to a particular destination. When talking about the best path, we consider p...

This paper presents a load balancing method to improve network utilization when static routing algorithms are employed. Static routing algorithms can generally be reduced to a path assignment problem with the aim of minimizing a cost function: i.e., maximizing network revenues. Unfortunately the problem, when multiple constraints such as different QoS traffic classes are present, is computation...

Modern telecommunication network is characterized by intensive growth and enormous capabilities. A huge number of users, types of services offered, and permanent trend of increasing the transfer rate make very difficult, or even impossible, to model, predict and control such a traffic. The paper describes the possible use of neural networks (NNs) in solving some problems arising in modern telec...

The massive introduction of technical advances in the Transport Network (Dense Wavelength Division Multiplexing, optical Crossconnects and Add Drop multiplexers), forced by bandwidth demand growth, creates new needs to manage it in an efficient and integrated way via a Common Control and Management Plane..The Generalized Multiprotocol Label Switching has been for several years the subject of IE...

This paper concerns the problem of minimizing the maximum link utilization of IP telecommunication networks under the joint use of traditional IGP routing protocols, such as IS–IS and OSPF, and the more sophisticated MPLS-TE technology. It is shown that the problem of choosing the optimal routing, both under working conditions and under single link failure scenarios, can be cast as a linear pro...

nowadays network-on-chips is used instead of system-on-chips for better performance. this paper presents a new algorithm to find a shorter path, and shows that genetic algorithm is a potential technique for solving routing problem for mesh topology in on-chip-network.

The routing algorithms can be classi®ed into source, distributed and hierarchical routing. Source routing algorithms are conceptually simple, but they suffer from scalability problem. Distributed routing algorithms are more scalable, but loops may occur, which make the routing to fail. Hierarchical routing has been used to cope with the scalability problems of source routing in large internetwo...

Optical network are used widely in all types of telecommunication networks. These have capability of transmitting large amount of data across the network. It uses the light beams to transmit data over various segment.WDM is a technology that plays a vital role in bandwidth utilization. By means of this technology the bandwidth can be utilized effectively and provide a better way of communicatio...
