An important problem in multifiber WDM networks is to decide how many fibers per link are required to guarantee high network performance. The fiber requirement may depend on many factors, e.g., the network topology, traffic patterns, the number of wavelengths per fiber, and the routing algorithm employed in the network. We study the fiber requirement under dynamic traffic in different topologie...

In the TCP network environment system the researcher and developer mainly focus on congestion control. The existing paper provides an analysis of congestion metric with or without flow of information in queue based AQM algorithms, on the basis of the algorithms, proposed a new algorithm APAQM (An Alternative path Active Queue Management Congestion control Algorithm). An Alternative path Active ...

We investigate the single link failure recovery problem and its application to the alternate path routing problem for ATM networks. Specifically, given a 2-connected graph G, a specified node s, and a shortest paths tree Ts = fe1; e2; : : : ; en 1g of s, where ei = (xi; yi) and xi = parentTs(yi), find a shortest path from yi to s in the graph Gnei for 1 i n 1. We present an O(m + n logn) time a...

Design/methodology/approach – Case studies were performed on three previously played ARGs to create case reports. The various digital information sources for each game, sourced from multiple media, are compiled into a chronologically ordered game narrative which formed the case reports. The focus of the article is on the analysis of the case reports using constant comparative analysis to identi...

The emergence of real-time applications, like Voice over IP and video conferencing, in IP networks implies a challenge to the underlying infrastructure. Several real-time applications have requirements on timeliness as well as on reliability and are accompanied by signaling applications to set up, tear down and control the media sessions. Since neither of the traditional transport protocols res...

ABSTRACT: MPLS is a promising technology which provides efficient routing and high speed switching. In recent years, emerging internet applications demand for high quality of service (QoS) guarantees. This paper mainly focuses on protection of data flow over MPLS network in case of any failure occurs in node/link. Network survivability can be affected by the faults in MPLS network. Existing app...

Alternative paths may significantly improve routing reliability in an IP network. One application of this technique is to enhance the reliability of the popular Open Shortest Path First (OSPF) routing protocol. In our proposed Reliable OSPF (ROSPF) routing protocol, one primary path and two alternate backup paths are deployed for data transmission. As expected, the number of shared links and ro...

-In this paper a practically efficient quality of service algorithm is proposed .Here we have a WARSHALS CONGESTION BASED algorithm for congestion path matrix to be retrieved .The algorithm provides the shortest congestion path matrix due to the congestion that is available in between the different vertex .The algorithm provides an alternate solution to the problem available using constant cong...

Nowadays traffic avoidance is most complicated problem in this urban area. This paper proposes how to avoid or quickly cross the traffic in large area based on Ant Colony Optimization (ACO) in VANET. It is proposed for identifying the best path to a destination in the simulation area. It has a traffic factor such as vehicle speed, number of vehicles percent in specific path, road capacity, and ...
