This paper proposes a macroscopic fluid dynamic model dealing with the flows of information on a telecommunication network with sources and destinations. The model consists of a conservation law for the packets density and a semilinear equation for traffic distributions functions, i.e. functions describing packets paths. We describe methods to solve Riemann Problems at junctions assigning diffe...

Designing low-cost networks that survive certain failure situations is one of the prime tasks in the telecommunication industry. In this paper we survey the development of models for network survivability used in practice in the last ten years. We show how algorithms integrating polyhedral combinatorics, linear programming, and various heuristic ideas can help solve real-world network dimension...

Multicast, or one-to-many, communication arises frequently in parallel computing and telecommunication applications. Multicast networks can simultaneously support multiple multicast connections between the network inputs and network outputs. However, due to the complex communication patterns and routing control in multicast networks, there is still a considerably large gap in network cost betwe...

With the increasing frequency of natural disasters and intentional attacks that challenge telecommunication networks, vulnerability to cascading and regional-correlated challenges is escalating. Given the high complexity and large traffic load of optical networks, these correlated challenges cause substantial damage to reliable network communication. In this paper, we propose a network vulnerab...

This dissertation investigates routing optimization in IP telecommunication networks, under normal working conditions as well as under failure conditions. The main objectives of the present optimization procedure are the minimization of the maximum link utilization in the network and to provide a configuration that guarantees a 100% survivability degree. Traditionally two different steps are us...

Traffic engineering is a method of optimizing the performance of a telecommunication network by dynamically analysing, predicting and regulating the link utilization over the network. It handles the unexpected traffic dynamics for achieving better quality of service and overall network performance in wireless sensor networks. One of the existing AMPLE (Adaptive Multi-topology traffic Engineerin...

This paper presents a partial implementation of the ES-IS Routing Information Exchange Protocol packet processing in Linux Kernel 2.6, which is for use in conjunction with the Connectionless Network Protocol (CLNP) in Aeronautical Telecommunication Network (ATN). First, we show the data structures involved in the protocol operation. Second, we describe the map of the packet processing whose des...
