An Approach to Off-Line Inter-domain QoS-Aware Resource Optimization
نویسندگان
چکیده
Inter-domain traffic engineering is a key issue when QoS-aware resource optimization is concerned. Mapping inter-domain traffic flows into existing service level agreements is, in general, a complex problem, for which some algorithms have recently been proposed in the literature. In this paper a modified version of a multi-objective genetic algorithm is proposed, in order to optimize the utilization of domain resources from several perspectives: bandwidth, monetary cost, and routing trustworthiness. Results show trade-off solutions and “optimal” solutions for each perspective. The proposal is a useful tool in inter-domain management because it can assist and simplify the decision process.

A New Fairness Index and Novel Approach for QoS-Aware Resource Allocation in LTE Networks Based on Utility Functions
Resource allocation techniques have recently appeared as a widely recognized feature in LTE networks. Most of existing approaches in resource allocation focus on maximizing network’s utility functions. The great potential of utility function in improving resource allocation and enhancing fairness and mean opinion score (MOS) indexes has attracted large efforts over the last few years. In this p...
متن کاملA Framework for Cooperative Inter-Domain QoS Routing
Currently, a straightforward way to design BGP-based Traffic Engineering (TE) tools for stub Autonomous Systems (AS) is to rely on selfish routing mechanisms. Although TE tools can find an optimal solution, this optimum represents only a local optimum for outbound traffic. Indeed, this is one of the main limitations of the selfish routing approach. This approach makes the TE tools unaware of th...

متن کاملPower-Aware Resource Allocation with Guaranteeing Fair QoS
In real-time systems, the execution of tasks with higher Quality of Service (QoS) requires larger resources and higher frequency in CPUs. Dynamic power-aware resource management using dynamic voltage scaling technique is needed to resolve a trade-off between the QoS maximization and the energy consumption minimization. By taking into the consideration a fairness of QoS levels of all tasks, we f...
