Models and Algorithms for Effective Traffic Engineering of Tunnel-based Backbone Networks a Dissertation

چکیده
In this dissertation, we explore the problem of effective traffic engineering of tunnel-based backbone networks. The approach is drawn from the observation that current techniques only account for requirements of the data plane towards engineering of networks. The impact is compounded by the stateful nature of tunnel-based networks. Our approach here is to incorporate control plane requirements through tunneling restriction to address a class of traffic engineering problems. First, we consider networks having heterogeneous streams (in terms of first and second order characteristics). Traffic streams are known to be heterogeneous due to diverse nature of applications which translates into distortion when they share tunnels with other streams. Using separate tunnels for each source could lead to overwhelming number

Quasi Random Deployment Strategy for Reliable Communication Backbones in Wireless Sensor Networks
Topology construction and topology maintenance are significant sub-problems of topology control. Spanning tree based algorithms for topology control are basically transmission range based type construction algorithms. The construction of an effective backbone, however, is indirectly related to the placement of nodes. Also, the dependence of network reliability on the communication path undertak...

متن کاملDifferent Network Performance Measures in a Multi-Objective Traffic Assignment Problem
Traffic assignment algorithms are used to determine possible use of paths between origin-destination pairs and predict traffic flow in network links. One of the main deficiencies of ordinary traffic assignment methods is that in most of them one measure (mostly travel time) is usually included in objective function and other effective performance measures in traffic assignment are not considere...
