Example (offline algorithm) Description
Offline_fa_xdeSharedRestoration
Solves several variants of unicast routing problems with flow-link formulations, so that designs are fault tolerant to a set of failure states, using shared restoration

Example (online event processor) Description
Online_evProc_generalProcessor
Implements the reactions of a technology-agnostic network to connection requests under various CAC options, and reactions to failures and repairs under different recovery schemes.

Keywords: CAC (Connection-Admission-Control), Network recovery: protection, Network recovery: restoration
Online_evProc_wdm
Implements the reactions of a WDM network carrying lightpaths in a fixed or flexi grid of wavelengths.

Keywords: WDM, Network recovery: protection, Network recovery: restoration
Online_evProc_ipOspf
Implements the reactions of an IP network governed by the OSPF/ECMP forwarding policies, for given link weigths This algorithm implements the reactions of an IP network governed by the OSPF/ECMP forwarding policies, for given link weigths, to the following events:
  • SimEvent.DemandAdd: Adds a new IP traffic demand, and recomputes the routing (now including the new traffic).
  • SimEvent.DemandRemove: Remvoes an IP traffic demand, and recomputes the routing.
  • SimEvent.DemandModify: Modifies the offered traffic of a demand, and recomputes the routing.
  • SimEvent.LinkAdd: Adds a new IP link to the network, recomputes the routing tables and the routing.
  • SimEvent.LinkRemove: Removes an existing IP link in the network, recomputes the routing tables and the routing.
  • SimEvent.LinkModify: Modifies the capacity of an IP link.

Online_evProc_ipOverWdm

Implements the reactions of an IP over WDM multilayer network, where the IP traffic is carried over lightpaths routed over a topology of fiber links with a fixed or a flexible wavelength grid.

Example (report) Description
Report_availability
This report receives as an input a network design, the network recovery scheme algorithm, and the network risks (SRGs), and estimates the availability of the network (including individual availabilities for each demand), using an enumerative process that also provides an estimation of the estimation error.

Keywords: Network recovery: protection, Network recovery: restoration
Report_perSRGFailureAnalysis
This report receives as an input a network design, the network recovery scheme algorithm, and a set of network risks (SRGs), and computes the availability of each network and each demand, in the no-failure state, and in each of the single-SRG failure states.
