public class Online_evProc_ipOspf
extends com.net2plan.interfaces.simulation.IEventProcessor

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. The routing is not modified, since OSPF does not react to capacity changes.
• SimEvent.NodesAndLinksChangeFailureState: Fails/repairs the indicated nodes and/or IP links, and reacts to such failures as OSPF does: the failed links are removed from the routing tables, and the network routing recomputed.

This module can be used in conjunction with the Online_evGen_generalGenerator generator for simulating IP/OSPF networks. See the technology conventions used in Net2Plan built-in algorithms and libraries to represent IP/OSPF networks.

Keywords:

• IP/OSPF, Network recovery: restoration

Input parameters:

ipMaximumE2ELatencyMs: Default: -1.0 Maximum end-to-end latency of the traffic of an IP demand to consider it as lost traffic (a non-positive value means no limit)
