Examples from category 'Resilience simulation - Provisioning algorithms'

Algorithms which reacts to failure/reparation events

Example nameDescription
NRSim_AA_doNothing.java

Do not react to failures

Keywords: None

Algorithm which implements a 'do nothing' resilience mechanism. Under failure, takes no action; while for reparations tries to restore to the primary path, provided that resources are available

NRSim_AA_genericProtectionAlgorithm.java

Generic provisioning algorithm using protection segments

Keywords: Protection algorithm

Algorithm which implements a generic protection mechanism using pre-defined protection segments in the network design.

NRSim_AA_genericRestorationAlgorithm.java

Generic provisioning algorithm based on restoration

Keywords: MPLS, Restoration algorithm

Algorithm which implements several restoration mechanisms: path/subpath/link restoration, and fast restoration.

NRSim_AA_OSPF_pathRerouting.java

Reroute all traffic according to the ECMP rule

Keywords: OSPF, Restoration algorithm

This algorithm reacts to any resilience event (failure/restoration) trying to routing all the traffic according to the ECMP rule, using link IGP weights. These weights are not modified by the algorithm.

NRSim_AA_WDM_pathRestoration.java

WDM Fast Reroute

Keywords: Regenerator placement, Restoration algorithm, WDM

This algorithm implements a local lightpath restoration mechanism. Since it assumes that the WDM network requires regenerators/wavelength converters, if the input design does not contain them, the algorithm computes the requirements of regeneration/conversion for each lightpath.
