You will see that ONOS will reroute the the traffic as shown in the figure.
Demo 5: Link recovery at Packet Layer
...
TBD
Possible demo scenarios
GUI representing the topology
Visualize topology
Visualize intents and path
N/W Topology Displays
N/W basic topology discovered from configuration
Display resource utilization - λ, BW before and after service demands
Display Intent actions and impacts
Show Intent Add, and removal procedures & results
Show Restoration at Optical Layer for Basic Functions
Show Resource Manager impacts and actions
Show Multilayer Graph Topology Graph Abstraction
Mininet Procedures to cause failures at OVS, and Linc-OE
Show impact of failures at ONOS graphically before and after restoration
Learning to Fly (Examples)
Network Topology Manipulation & Updates (How you can modify the Python and Explain the Topology, Interfaces, Hosts)
Hosts / Data Centers attached to Packet Networks
Packet nodes interconnected with Optical nodes
Traffic between the data centers
Setting up Connection between data centers
GUI , CLI Options
Causing Failure at Optical Layer
Causing Failures at Packet Layer
Changing to a much bigger Topology
Temporary text:
This Demo has three basic core operations:
1- ONOS ability to discover multilayer topologies and directly control the devices (at both Packet and Optical)
2- Compiling the service requests ( BW-on-Demand) into a set of data path forwarding actions at both packet and optical layer
3- Restoration models at each layer ( Packet & optical) failures
This GUI represents the same topology that we just showed you!
We have attached the Topology to the ONOS in such a way that it can be discovered by ONOS as changes happens in the data plane.
ONOS now should be full aware of the both packet and optical topology.
Notice that we have now established 2 service requests the Optical layer represents the physical circuits or transports, and the packet layer represents the logical paths between them
Next we should try to explain the automatic restoration:
Playing with bigger topology.
We have also provide python script with bigger topology, "opticalTestBig.py"
We highly encourage you to run that topology and play with it and give us you feed back.
