Class OptDivideTMLoadComputer

java.lang.Object
  be.ac.ulg.montefiore.run.totem.repository.optDivideTM.OptDivideTMLoadComputer

All Implemented Interfaces:

TmLoadComputer

public class OptDivideTMLoadComputer
extends java.lang.Object
implements TmLoadComputer

This class implements a Traffic Engineering method which consist to divide the traffic matrix into N sub-matrices (called strata). Each stratum is routed independently of each other. Concerning the implementation of such solution, it is possible to establish multiple MPLS full-mesh (N) or to use the Multi-Topology functionality (N multiple topologies).
