public class Online_evGen_ipOverWdm
extends Online_evGen_generalGenerator

Generates events for an IP over WDM multilayer network, with an IP/OSPF layer on top of a WDM layer where lightpaths are carried in a fixed grid of wavelengths This class extends the Online_evGen_generalGenerator generator (see its Javadoc for further details), and is basically used to:

• Send events to the IP layer to create used-defined IP traffic fluctuations (fast/slow), according to the general operation of the Online_evGen_generalGenerator module.
• Send events related to node/link failures and repairs, also according to how the Online_evGen_generalGenerator module operates.

See the technology conventions used in Net2Plan built-in algorithms and libraries to represent IP and WDM networks.

Keywords:

• IP/OSPF, WDM, Multilayer, Network recovery: protection, Network recovery: restoration, Multihour optimization

Input parameters:

ipOverWdmFailureModel: Value to select within {perBidirectionalLinkBundle, none, SRGfromNetPlan, perNode, perLink, perDirectionalLinkBundle} Failure model selection: SRGfromNetPlan, perNode, perLink, perDirectionalLinkBundle, perBidirectionalLinkBundle ipOverWdmFailureDefaultMTTFInHours: Default: 10.0 Default value for Mean Time To Fail (hours) (unused when failureModel=SRGfromNetPlan) ipOverWdmFailureDefaultMTTRInHours: Default: 12.0 Default value for Mean Time To Repair (hours) (unused when failureModel=SRGfromNetPlan) ipOverWDmFailureStatisticalPattern: Value to select within {exponential-iid} Type of failure and repair statistical pattern randomSeed: Default: 1 Seed for the random generator (-1 means random) ipTFFastFluctuationType: Value to select within {none, random-truncated-gaussian} ipTFFastTimeBetweenDemandFluctuationsHours: Default: 0.1 Average time between two changes of demand offered traffic in a demand (demands behave independently) ipTFFastFluctuationCoefficientOfVariation: Default: 1.0 Average time between two changes of demand offered traffic in a demand (demands behave independently) ipTFFastMaximumFluctuationRelativeFactor: Default: 1.0 The fluctuation of a demand cannot exceed this percentage from the media ipTFSlowStartDate: Default: 07/11/18 08:58:25 Initial date and time of the simulation ipTFSlowTimeBetweenDemandFluctuationsHours: Default: 1.0 Average time between two changes of demand offered traffic in a demand (demands behave independently) ipTFSlowDefaultTimezone: Default: 0 Default timezone with respect to UTC (in range [-12, 12]) ipTFSlowFluctuationType: Value to select within {none, time-zone-based}
