  1. ProtocolSessions in GLASS

  2. ProtocolSession in SSFNet

  3. ProtocolSession in SSFNet • ProtocolGraph is the container for all the protocols available in a node • This container configures and initializes the protocols when running a simulation • ProtocolSession is the instance of the service running in a node • It is configurable via DML file • ProtocolMessage is the entity that is exchanged between two protocols via the method push(ProtocolMessage msg, ProtocolSession fromSession)

  4. ProtocolSession in SSFNet • PacketEvent is the entity used to exchange information between nodes

  5. Simple Protocol • Description • Test and validate the behavior of the optical components • On top of the OXCSwitch and does not need IP • Requests a light path • Package and Related Classes • SimpleProtocol – gov.nist.antd.merlin.protocol.sample • SimpleProtocolHeader – the same package

  6. Simple Protocol • DML Schemas • ProtocolSession [ name simpleProtocol use gov.nist.antd.merlin.protocol.sample.SimpleProtocol destination %I routing %S (default : ShortestPathDistance) wavelength %S (default : BestFit) bandwidth %S (default : 2.5Gbps) delay %F (default : 0.1s) (between two transmissions) ]

  7. Simple Protocol • Behavior • Creation of the quality of service that matches the configuration • Request of a connection by using the instant lightpath establishment. This is provided by the class gov.nist.antd.merlin.util.ConnectionUtil • If a path is found, register to it • Send messages with the delay that is given as input in the configuration

  8. Simple Protocol • Content of Message • “Hello from <sourceID> to <destinationID>”

  9. Simple Protocol • Example ProtocolSession [ name hello use gov.nist.antd.merlin.protocol.sample.SimpleProtocol routing shortestPathSRLG wavelength bestFit destination 18 delay 0.1 ]

  10. Neighbor Discovery • Goal : To create a table of neighbors for a node and how they can be reached • ProtocolSession [ name SimpleOpticalNeighbourDiscovery use gov.nist.antd.merlin.protocol.discovery .OptNeighbour ]

  11. Backup Manager • Goal : A backup protocol of link protection • ProtocolSession [ name BackupManager use gov.nist.antd.merlin.protocol.protectionlink. BackupManager BACKUPALGORITHM ShortestPathDistanceSRLG ]

  12. Topology Manipulator • Goal : use generator to create failures or other events • ProtocolSession [ name topologyManipulator use gov.nist.antd.merlin.generator.event .TopologyManipulator generator [ use gov.nist.antd.merlin.generator.event .RandomEventGenerator ] ]

  13. Traffic Manager • Goal : use for traffic generate • global [ ProtocolSession [ name trafficManager use gov.nist.antd.merlin.generator.traffic.TrafficManager generator [ use gov.nist.antd.merlin.generator.traffic .RandomTrafficGenerator active true ] ] ]

  14. Dynamic Recovery • Goal : Dynamic Route Recovery Protocol for optical networks • ProtocolSession [ name DynRecovery use gov.nist.antd.merlin.protocol.signaling .DynRecovery BCKUPALGO ShortestPathDistanceSRLG debug (true or false) //print all the debug info. message (true or false) /*print the content of all message it handles*/ ]
