Example (online event processor) Description
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.
