Delivering desired QoS to the applications is one of the most important challenges in next generation networks. Designing efficient queue management in midway nodes leads to improvement in NGN efficiency. This paper presents fair Efficient active Queue Management (EQM) mechanism for congestion avoidance and control in next generation networks. Proposed AQM mechanism uses instantaneous queue length...
The QoS is a key measure for satisfaction level of next-generation network (NGN). QoS multicast routing is becoming an urgent problem to promote NGN. An optimization mode is proposed for it, and an immune inspired algorithm is designed to solve the model. The simulation study shows the promising effects of the model and the algorithm. The study can meet the requirements of NGN performance optimization.
Traffic engineering, particularly routing optimization, is one of the most important aspects to take into account when providing QoS in next generation networks (NGN). The problem of weight setting with conventional link state routing protocols for routing optimization has been object of study by a few authors. To solve this problem for big networks artificial intelligence heuristics have been used,...
This article addresses the bandwidth management problem in differentiated-service-aware traffic engineering (DS-TE) in MPLS networks. In this context diverse bandwidth constraint (BC) models have been proposed to enforce bandwidth constraints for each class of traffic on the basis of the resource optimization objectives. This article is not aimed at designing new models but to describe the framework...
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...
