From 489f6ec97e8ba82a063da1bbcc6f46c72e8a5c3f Mon Sep 17 00:00:00 2001 From: Sumit Naiksatam Date: Tue, 5 Feb 2013 20:25:46 -0800 Subject: [PATCH] L3 API support for BigSwitch-FloodLight Plugin In keeping with the philosophy of the RESTProxy plugin, L3 extension calls are processed (CRUD of logical resources) and the state changes are proxied to a backend controller. A configuration variable specific to the RESTProxy plugin is being added to identify that particular Quantum server's ID. blueprint quantum-floodlight-bigswitch-l3 Change-Id: I24be02cd836352497fe5b1e7622d138e0c816377 --- etc/quantum/plugins/bigswitch/restproxy.ini | 16 +- quantum/plugins/bigswitch/plugin.py | 696 +++++++++++++++--- quantum/plugins/bigswitch/vcsversion.py | 27 + quantum/plugins/bigswitch/version.py | 12 +- .../tests/unit/bigswitch/test_router_db.py | 317 ++++++++ 5 files changed, 942 insertions(+), 126 deletions(-) create mode 100644 quantum/plugins/bigswitch/vcsversion.py create mode 100644 quantum/tests/unit/bigswitch/test_router_db.py diff --git a/etc/quantum/plugins/bigswitch/restproxy.ini b/etc/quantum/plugins/bigswitch/restproxy.ini index 957179795b..afe71f4666 100644 --- a/etc/quantum/plugins/bigswitch/restproxy.ini +++ b/etc/quantum/plugins/bigswitch/restproxy.ini @@ -28,13 +28,13 @@ reconnect_interval = 2 # # The following parameters are supported: # servers : [,]* (Error if not set) -# serverauth : (default: no auth) -# serverssl : True | False (default: False) -# syncdata : True | False (default: False) -# servertimeout : 10 (default: 10 seconds) +# server_auth : (default: no auth) +# server_ssl : True | False (default: False) +# sync_data : True | False (default: False) +# server_timeout : 10 (default: 10 seconds) # servers=localhost:8080 -#serverauth=username:password -#serverssl=True -#syncdata=True -#servertimeout=10 +#server_auth=username:password +#server_ssl=True +#sync_data=True +#server_timeout=10 diff --git a/quantum/plugins/bigswitch/plugin.py b/quantum/plugins/bigswitch/plugin.py index 5105da748e..8566e72099 100644 --- a/quantum/plugins/bigswitch/plugin.py +++ b/quantum/plugins/bigswitch/plugin.py @@ -45,18 +45,24 @@ on port-attach) on an additional PUT to do a bulk dump of all persistent data.
