Telecommunication and grid computing applications demand high bandwidth data channels that offer guarantees with respect to service availability. Such applications include: remote surgery, remote experimentation, video on-demand (VOD), teleconferencing, and bulk transfers. Furthermore, by forecasting traffic patterns internet service providers (ISP) attempt to optimize network resources in orde...

IEEE 802.6 metropolitan area networks (MANs) provide an efficient architecture for supporting wireless personal communication services (PCSs) over metropolitan areas by interconnecting wireless base stations into personal communication networks (PCNs). They also serve as peripheral gathering networks to transport PCS traffic over a wide area broadband integrated services digital network employi...

Fluid models are appropriate in the field of telecommunication for modelling the network traffic where individual units of arrival have less impact on the performance of the network. Such models characterize the traffic as a continuous stream with a parameterized flow rate. For practical design and performance evaluation, it is essential to obtain information about the buffer occupancy distribu...

Survivability refers to keeping a system partially or fully operational when one or more of its components fail. Survivability in telecommunication networks is crucial, as failure of a network component can potentially bring down the whole communication network, as happened in some real-world cases. Adding redundant network components increases the survivability of a network, but cost of the ne...

User-perceived application-level performance is very important in the adoption and success of UMTS (Universal Mobile Telecommunication System) services and infrastructure. To predict this performance, a detailed end-to-end UMTS network performance simulator was developed. The simulator allows the modeling of application traffic characteristics, network architecture, network elements, and protoc...

This paper presents a study of base station system configurations for the Universal Mobile Telecommunication System (UMTS). The base station system (BSS), being the interface between the mobile terminal and fixed network, should be capable of handling a huge amount of traffic, mobility, and a high signaling load which is expected in the UMTS. Several functions that should be supported by BSS ar...

We study a class of noncooperative general topology networks shared byN users. Each user has a given flow which it has to ship from a source to a destination. We consider a class of polynomial link cost functions, adopted originally in the context of road traffic modeling, and show that these costs have appealing properties that lead to predictable and efficient network flows. In particular, we...

Traffic prediction plays an important role in evaluating the performance of telecommunication networks and attracts intense research interests. A significant number of algorithms and models have been put forward to analyse traffic data and make prediction. In the recent big data era, deep learning has been exploited to mine the profound information hidden in the data. In particular, Long Short-...

Pricing for the use of telecommunication services is an issue widely treated in the literature. In the last years it has received a growing attention in order to establish various fairness criteria in the bandwidth allocation for each type of traffic class. A number of pricing models have been proposed and analyzed in the context of Quality of Service (QoS) guaranteed networks (e.g. ATM, IP Int...

We study the best OSPF style routing problem in telecommunication networks, where weight management is employed to get a routing configuration with the minimum oblivious ratio. We consider polyhedral demand uncertainty: the set of traffic matrices is a polyhedron defined by a set of linear constraints, and the performance of each routing is assessed on its worst case congestion ratio for any fe...
