In modern optical networks, infrastructure management is faced with the challenge of using expensive equipment and communication resources as efficiently as possible. This now includes keeping power consumption costs at a minimum and using the available optical links in a balanced way, in addition to the traditional goals of providing the best possible performance to the end customers while meeting...
This paper describes routing programming solutions in the Mininet virtualized software-defined network. There are two challenges in implementing SDN into convergent LTE/WiFi network. The first challenge is measuring the QoS parameters by means of external network load monitoring systems. The second challenge is disuse of QoS-based routing by vendors because of high requirements of real-time load balancing...
In this paper for the first time the mathematical model and the two-level method of fault-tolerant inter-domain routing in telecommunications networks was presented. The novelty of the model is its decomposed representation and formulation the inter-area interworking conditions. The implementation of these conditions guaranteed the connectivity of calculated inter-area paths. The research of the proposed...
In providing new telecommunication services, the requisition for quality of network is more and more popular and sophisticated with high bandwidth, small value of delay time or packet loss etc. To assure the quality of network, the localized routing schemes have recently been researched as a promising alternative to the currently deployed global QoS routing schemes. Different from the traditional...
A definition of overall telecommunication network performance is presented. A model of overall virtual telecommunication network (VNET), with QoS guaranties for Class 0 traffic (Real-time, jitter sensitive, high interaction: VoIP, Video Teleconference), is considered in stationary state, taking into account details of the users' behaviour. The approach described allows reducing the number of system...
This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
In this paper, we introduce a pricing model that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. Specifically, a dynamic allocation policy is examined that relies on online measurements while each service class operates under a probabilistic bound delay constraint. We present a rigorous analysis of the properties of...
