    Modeling Spreading of Failures in GMPLS-Based Networks

    In this paper, a new model to simulate different failure propagation scenarios in GMPLS-based networks is proposed. Different types of failures and malfunctions may spread along the network following different patterns (hardware failures, natural disasters, accidents, configuration errors, viruses, software bugs, etc). Current literature presents several models describing how failures...

    An Improved Method for Discovering Link Criticality in Transport Networks

    Quantitatively assessing the importance or criticality of each link in a network is of practical value to operators, as that can help them to increase the network's resilience, provide more efficient services, or improve some other aspect of the service. Betweenness is a graph-theoretical measure of centrality that can be...

    New Applications of the Betweenness Centrality Concept to Reliability-Driven Routing

    Depending on network properties and the policies applied by its operator, certain links can play a central role in the sense that a large proportion of traffic passes through them, while others might be on the periphery. Understanding the relative importance or centrality of links has several potential applications. For...

    A Performance Analysis of Carrier Ethernet Schemes Based on Multiple Spanning Trees

    Due to recent advances, Ethernet is starting to move from Local area networks to carrier networks. Nevertheless as the requirements of carrier networks are more demanding, the technology needs to be enhanced. Schemes designed for improving Ethernet to match carrier requirements can be categorized in two classes. The first class...

    A Dynamic Multilevel MPLS Protection Domain

    MPLS can be used to support advanced survivability requirements and to enhance the reliability of IP networks. MPLS networks have the capability to establish Label Switched Paths LSPs (similar to the Virtual Circuits concept). This allows MPLS domains to pre-establish protection LSPs, backups for the working LSPs, and achieve better...

    A QoS Framework for Heterogeneous Wireless Networks Using a Multiagent System

    Heterogeneous wireless networks will converge into a single network, making the majority of services independent of the access technologies. Thus, current and emerging wireless technologies will belong to a multi-tier system that will interoperate with different wired backbone networks and will have to provide Quality of Service (QoS) guarantees. The...

    Dynamic Unicast/Multicast Traffic Grooming Using S/G Light-Tree in WDM Networks

    Internet traffic demands are constantly increasing and a considerable amount is expected to be of multicast type. Optical Transport Networks (OTN) must be prepared in terms of better resource utilization, for accommodating unicast and multicast traffic together. Dynamic traffic grooming in optical mesh networks is one of the most important...
