Resource Assignment in Multi-service Survivable Networks Based on the Cycle-oriented Approach

چکیده
Abstract: Service Convergence is a prospective goal to reach considerable economic benefits in a Multi-Service Network (MSN) environment. Elements such as Multi-Service Provisioning Platforms and Multi-Technology Network Management systems together with suitable MSN modeling are the key underlying components supporting that goal. The paper relates to the framework of MSN modeling and specifically addresses the issue of assigning working and redundant resources in an MSN environment so as to provide differential survivability. In this paper we specify aspects of MSN survivability, explain the Cycle-oriented approach for Path Protection/Restoration and the associated survivable traffic types to be supported. We detail two network models for optimal resource allocation with special emphasis on large-network considerations and present some typical results that reflect the strengths of the network models developed.

The problem we investigate deals with the optimal assignment of resources to the activities of a stochastic project network. We seek to minimize the expected cost of the project include sum of resource utilization costs and lateness costs. We assume that the work content required by the activities follows an exponential distribution. The decision variables of the model are the allocated resourc...

Therefore, the main purpose of this paper is to introduce a suitable framework for human capital eva...
متن کاملConstrained consumable resource allocation in alternative stochastic networks via multi-objective decision making
Many real projects complete through the realization of one and only one path of various possible network paths. Here, these networks are called alternative stochastic networks (ASNs). It is supposed that the nodes of considered network are probabilistic with exclusive-or receiver and exclusive-or emitter. First, an analytical approach is proposed to simplify the structure of t...

This paper concerns sub-channel allocation in multi-user wireless networks with a view to increasing the network throughput. It is assumed there are some sub-channels to be equally divided among active links, such that the total sum rate increases, where it is assumed each link is subject to a maximum transmit power constraint. This problem is found to be a non-convex optimization problem and i...
