Tutorial Iperf + ODL-SDN

This tutorial will guide you through the definition of the iperf and odlsdn example.

Take your experiment.yaml file, and write something like this :

---
sdn_ericsson:
      properties:
        resource_id: sdn-controller-odl-ericsson
      type: SdnResource

The new experiment.yaml file will be something like this

---
description: "Template for SoftFIRE yaml resource request definition"
imports:
  - softfire_node_types: "http://docs.softfire.eu/etc/softfire_node_types.yaml"

topology_template:
  node_templates:


    iperf:
      type: NfvResource
      properties:
        resource_id: iperf
        nsd_name: The Iperf NSD
        testbeds: { ANY: ericsson }
        ssh_pub_key: "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDNo3y5JdeIzeIBbpQEEtjn/BgBjTzyAo7HeSPAy9tZfXpOt0P/rGaflRSiAOTk+P+kHs9GMFQrA3nfk6z9Ass18BTUmtNvovyQphqcEAAAADAQABAAABAQDNDtULVF+n3/znwENEga+5Fl6qvVzWWMepb02q41VvaZy/NoMHnw9+NwNiM1BY9AAy2+Z6AIg8CJ1EvIZTPlD7a7RveSjLHZLuVeBGZdOky1EQf+m8VpPvM2axrdtluch/bJXPKVJQhF7Wc4HSFxdAhxhGPSeyNMPqQ/EcevZQMic0qJ82GKsWFm5M+Fy4x1wsOG5aJ918Za29aiKMrUv8Borod7b2YCBb"


    sdn_ericsson:
      properties:
        resource_id: sdn-controller-odl-ericsson
      type: SdnResource


tosca_definitions_version: tosca_simple_yaml_1_0

after that create the CSAR file, upload to the Experiment Manager GUI. If there are no mistakes, you are able to deploy your resources by clicking deploy. Once deployed, in the details of the experiment a section is displayed for sdn-controller-odl-ericsson

Note

To create, upload a CSAR file and deploy your resources view a tutorial.

The value contains somethings like this :

{
    "resource_id": "sdn-controller-odl-ericsson",
    "token": "x1x1x1x1x1x1x1x1x1x1x1x1x",
    "flow-table-range": [
        2,
        3,
        4
    ],
    "URI": "http://172.20.70.130:8001/"
}

- "token" is needed to call the rest API - "flow-table-range" are the tables that odl assigned to the experimenter - "URI" is the ODL endpoint used for RESTCONF API requests

REST put flow example - drop all packets with destination ip equals to 10.0.10.2/24:

curl -X PUT \
  'http://<URI>/restconf/config/opendaylight-inventory:nodes/node/openflow:72664714402125/table/2/flow/1' \
  -H 'accept: application/json' \
  -H 'api-token: <token>' \
  -H 'cache-control: no-cache' \
  -d '{
      "flow-node-inventory:flow": [
        {
          "id": "1",
          "flow-name": "Foo",
          "match": {
            "ipv4-destination": "10.0.10.2/24",
            "ethernet-match": {
              "ethernet-type": {
                "type": 2048
              }
            }
          },
          "priority": 2,
          "table_id": 2,
          "instructions": {
            "instruction": [
              {
                "order": 0,
                "apply-actions": {
                  "action": [
                    {
                      "order": 0,
                      "drop-action": {}
                    }
                  ]
                }
              }
            ]
          }
        }
      ]
    }'

Note

When you delete the experiment, OLD will de-associate and clean the tables that were assigned.
