Class MIRA

java.lang.Object
  it.unina.repository.MIRA.MIRA

All Implemented Interfaces:

DomainSyncAlgorithm, LSPPrimaryRouting, TotemAlgorithm

public class MIRA
extends java.lang.Object
implements LSPPrimaryRouting, DomainSyncAlgorithm

This class implements the integration of MIRA (Unina). This is the algorithms described in : NewMira (Wang, B., Su, X., Chen, C.: A New Bandwidth Guaranteed Routing Algorithm for MPLS Traffic Engineering. In Proceedings of IEEE International Conference on Communications, ICC 2002) Simple MIRA (Iliadis, I., Bauer, D.: A New Class of Online Minimum-Interference Routing Algorithms.
