Getting Started

• Start off by changing the value of BASE_URL in utilClasses.py to match the address of the ONOS controller.
• Describe the topology to be deployed in the file g.gragh, where each line represents a single edge/link in the topology
  • Source Destination Link_Capacity
  • If the Source starts with h, the node is considered a host; e.g. h1, h20
• Deploy the topology by running sudo ./mntopo.py, the script creates a Mininet network from the topology described in g.graph, and connects the switches to the ONOS controller deployed locally localhost.
• Due to ONOS not discovering the hosts until they generate some traffic, running the pingall command in Mininet is advised.
• Run the main script ./intentapp.py to start BWO.

BWO Commands

BWO currently supports four types of commands:

1. Adding Intents: add {src_host} {dst_host} {Demand}
2. Listing Intents: (list | ls)
3. Removing intents: (rm | remove | delete) ({Intent ID} | all)
4. Exiting BWO: exit
