kyto-ng/sdx

Kytos-ng Napp that implements SDX Integration

Overview

This Napp allows the integration of AtlanticWave SDX components into Kytos-ng SDN orchestrator. The integration allows Kytos-ng sending the network Topology to SDX-LocalController, following the Topology Data Model Specification, as well as provisioning and operation of L2VPN Point-to-Point.

Getting started

To install this NApp, first, make sure to have the same venv activated as you have kytos installed on:

$ git clone https://github.com/atlanticwave-sdx/kytos-sdx
$ cd kytos-sdx
$ python3 setup.py develop

The easiest way of using this Napp is through the Docker container:

$ docker build -t kytos-sdx .
$ docker exec -it mongo mongo --eval 'db.getSiblingDB("kytos").createUser({user: "kytos", pwd: "kytos", roles: [ { role: "dbAdmin", db: "kytos" } ]})'
$ docker run -d --name kytos-sdx --link mongo -e SDXLC_URL=http://192.168.0.100:8080/SDX-LC/2.0.0/topology -e OXPO_NAME=Test-OXP -e OXPO_URL=test-oxp.net -e MONGO_DBNAME=kytos -e MONGO_USERNAME=kytos -e MONGO_PASSWORD=kytos -e MONGO_HOST_SEEDS=mongo:27017 -p 8181:8181 kytos-sdx

Requirements

• kytos/topology
• kytos/mef_eline

General Information

The SDX Napp supports topology operations and L2VPN provisioning operations. Some examples:

Get Kytos-ng SDX Topology

curl -s -X GET http://127.0.0.1:8181/api/kytos/sdx/topology/2.0.0

Send Topology to SDX-LC

• Submit the Kytos-ng SDX Topology to SDX-LC (push topology sharing method):

curl -s -X POST http://127.0.0.1:8181/api/kytos/sdx/topology/2.0.0

Create L2VPN with old API

• Create a L2VPN using the old Provisioning APIs (currently being used by SDX-LC):

curl -s -X POST -H 'Content-type: application/json' http://127.0.0.1:8181/api/kytos/sdx/v1/l2vpn_ptp -d '{"name": "AMPATH_vlan_503_503", "uni_a": {"port_id": "urn:sdx:port:ampath.net:Ampath3:50", "tag": {"value": 501, "tag_type": 1}}, "uni_z": {"port_id": "urn:sdx:port:ampath.net:Ampath1:40", "tag": {"value": 501, "tag_type": 1}}, "dynamic_backup_path": true}'

Delete L2VPN with old API

• Delete a L2VPN using the old Provisioning APIs (currently being used by SDX-LC):

curl -s -X DELETE -H 'Content-type: application/json' http://127.0.0.1:8181/api/kytos/sdx/v1/l2vpn_ptp -d '{"name": "AMPATH_vlan_503_503", "uni_a": {"port_id": "urn:sdx:port:ampath.net:Ampath3:50", "tag": {"value": 501, "tag_type": 1}}, "uni_z": {"port_id": "urn:sdx:port:ampath.net:Ampath1:40", "tag": {"value": 501, "tag_type": 1}}, "dynamic_backup_path": true}'

Create L2VPN with new API

• Create a L2VPN using the new Provisioning API (many examples):

# Example 01: minimal attributes (requierd)
curl -s -X POST -H 'Content-type: application/json' http://127.0.0.1:8181/api/kytos/sdx/l2vpn/1.0 -d '{"name": "AMPATH_vlan_501_501", "endpoints": [{"port_id": "urn:sdx:port:ampath.net:Ampath3:50", "vlan": "501"}, {"port_id": "urn:sdx:port:ampath.net:Ampath1:40", "vlan": "501"}]}'

# Example 02: minimal attributes with endpoint.0 being all (frames with and without 802.1q headers)
curl -s -X POST -H 'Content-type: application/json' http://127.0.0.1:8181/api/kytos/sdx/l2vpn/1.0 -d '{"name": "AMPATH_vlan_all_503", "endpoints": [{"port_id": "urn:sdx:port:ampath.net:Ampath3:50", "vlan": "all"}, {"port_id": "urn:sdx:port:ampath.net:Ampath1:40", "vlan": "503"}]}'

# Example 03: range of VLAN
curl -s -X POST -H 'Content-type: application/json' http://127.0.0.1:8181/api/kytos/sdx/l2vpn/1.0 -d '{"name": "AMPATH_vlan_512:534_512:534", "endpoints": [{"port_id": "urn:sdx:port:ampath.net:Ampath3:50", "vlan": "512:534"}, {"port_id": "urn:sdx:port:ampath.net:Ampath1:40", "vlan": "512:534"}]}'

# Example 04: example with all possible attributes
curl -s -X POST -H 'Content-type: application/json' http://127.0.0.1:8181/api/kytos/sdx/l2vpn/1.0 -d '{"name": "AMPATH_vlan_503_503", "endpoints": [{"port_id": "urn:sdx:port:ampath.net:Ampath3:50", "vlan": "501"}, {"port_id": "urn:sdx:port:ampath.net:Ampath1:40", "vlan": "501"}], "description": "test foobar xpto aa bbb", "scheduling": {"start_time": "2024-08-07T19:55:00Z", "end_time": "2024-08-07T19:58:00Z"}, "notifications": [{"email": "user@domain.com"},{"email": "user2@domain2.com"}], "qos_metrics": {"min_bw": {"value": 5,"strict": false}, "max_delay": {"value": 150, "strict": true}}}'

Edit L2VPN with new API

• Editing a L2VPN using the new Provisioning API:

curl -H 'Content-type: application/json' -X PATCH http://127.0.0.1:8181/api/kytos/sdx/l2vpn/1.0/f9ecff1309d845 -d '{"endpoints": [{"port_id": "urn:sdx:port:ampath.net:Ampath3:50", "vlan": "301"}, {"port_id": "urn:sdx:port:ampath.net:Ampath1:40", "vlan": "4095"}], "description": "this is a l2vpn test"}'

The example above changes the endpoints and the description of a L2VPN. Fields that can be changed: endpoints, description, scheduling, qos_metrics, name. Note about endpoints: if one endpoint has to be changed, you must provide both endpoints.

Delete L2VPN with new API

• Delete a L2VPN using the new Provisioning API:

curl -s -X DELETE http://127.0.0.1:8181/api/kytos/sdx/l2vpn/1.0/ea492fd1238e4a
