    Abstract

    Nowadays, transport networks, carry extremely large amounts of network traffic, and are widely spread across multiple geographical locations. As a result, any possible connectivity failure could directly impact the service delivery of a vast amount of users. Therefore, the network should be able to recover fast from a failure in order to provide service continuity to the user. Several recovery techniques have been employed by the Internet Service Providers (ISPs) such as adding redundancy to network equipment (e.g. routers, optical cross-connects, etc.), or by provisioning alternate paths (path protection, path restoration) X[1]X. Hence,
    assuming sufficient resources, network resilience can be achieved when a single failure occur (e.g. fiber cut). However, when it comes to simultaneous failures such as cascading and epidemic failures, the available solutions are expensive X[2]X. For Generalized Multi Protocol Label Switching (GMPLS) transport networks, network survivability under multiple failures has been discussed in X[3]X-X[5]X. Virus propagation models from the field of epidemiology have been altered for simulating
    network failure scenarios and the failure propagation probability within the network X[6]X[7]X. This paper evaluates the reliability of a GMPLS transport network under epidemic failure scenarios. Thus, the aim is to increase the fault tolerance of the GMPLS technology when simultaneous failures occur impacting a large number of network nodes across an optical transport network (OTN) in order to ensure the service delivery. The remainder of the paper is organized as follows: Section 2 describes the GMPLS framework. Section 3 deals with epidemic failures. The simulation study and its results are presented in section 4. Section 5 concludes the paper.
