Agenda for today’s meeting (tbachman, 16:06:39)
* SFC Demo from Ricky (tbachman, 16:06:45)

Link to document describing the demo (tbachman, 16:07:34)
* ericano_ presents demo on SFC that uses an HTTP proxy (SQUID) to
show traffic traversing different chains (tbachman, 16:08:54)
* The motivation for the demo is to be able to easily set up and use
ODL SFC (tbachman, 16:09:14)
* The demo graphically shows which service chain a client is using;
this is done using a client talking to an apache web server, which
traverses different chains that add HTTP headers to change the color
of a web page (tbachman, 16:10:03)
* ACTION: ebrjohn to send an email to the SFC ML with a link to
today’s presentation (tbachman, 16:10:58)
* The demo uses two classifiers, two SFFs, and two SFs (tbachman,
16:11:13)
* The demo uses 3 service chains. (tbachman, 16:11:33)
* Chain #1 just traverses SF1, which colors the web page blue
(tbachman, 16:11:46)
* Chain #2 just traverses SF2, which colors the web page red
(tbachman, 16:11:56)
* Chain #3 traverses SF1 and SF2, which colors the web page purple
(tbachman, 16:12:11)
* The demo uses a vagrant setup, which makes it easy to stand up and
use (tbachman, 16:13:21)
* ericano_ says the script starts the controller, which runs in one of
the VMs (tbachman, 16:13:50)
* lmcdasm asks what’s been defined by the demo (tbachman, 16:21:37)
* ericano_ says it defines the SF types, SFFs, etc. (tbachman,
16:21:50)
* ericano_ says that instead of using the gui, the configuration is
pushed using REST calls (tbachman, 16:22:10)
* the demo has some tools to help — such as a tool to show clients,
list rendered service paths, and assign paths to clients (tbachman,
16:24:51)
* lmcdasm asks if the reason that you need the classifier function is
that you never know what the classifier is until you have a client
(tbachman, 16:25:33)
* ebrjohn says that this demo doesn’t use NSH, so there’s a bit of a
workaround for the classifier for the demo (tbachman, 16:25:55)
* meenakshi asks if the RSPs is information from ODL (tbachman,
16:26:36)
* ebrjohn says yes (tbachman, 16:26:39)
* meenakshi asks if the RSP IDs are a result of RSP creation
(tbachman, 16:26:55)
* ebrjohn says yes (tbachman, 16:26:58)
* ebrjohn says the REST sender tool can be used to query the datastore
to query/list the RSPs, if desired (tbachman, 16:27:17)
* lmcdasm asks if this informed mininet about the RSPs that were
assigned to the client (tbachman, 16:28:19)
* ericano_ says yes (tbachman, 16:28:21)
* ericano_ says the header enrichment isn’t yet running — need to open
consoles on the SFs and start the process for header enrichment
(tbachman, 16:28:57)
* ericano_ says there are scripts in the demo to do that (tbachman,
16:29:05)
* lmcdasm asks if we’re using an SFF at this point (tbachman,
16:31:12)
* ericano_ says yes (tbachman, 16:31:16)
* lmcdasm asks if you have to unassociate with the first chain before
associating the second chain, or is this done automatically
(tbachman, 16:34:33)
* ebrjohn says the client tool is just setting up the classifier — the
RSPs are there (tbachman, 16:35:06)
* ebrjohn says in a big scenario, you could have a DPI or PCRF (Policy
Control Routing Function) controlling the classifier (tbachman,
16:36:34)
* meenakshi asks where the classifier flows are programmed in the
demo? Is it at the client? At the SFF? (tbachman, 16:37:55)
* ebrjohn says there is an ingress and egress classifier switch — and
those are where the classifiers are programmed (tbachman, 16:38:26)
* ebrjohn says the classifier switches are separate from the SFs and
SFFs (tbachman, 16:38:40)
* ebrjohn says the only thing the classifier does is an L2 to L4
classification and assigns the RSP (tbachman, 16:42:58)
* ebrjohn says he’d like to discuss Beryllium planning, but probably
not enough time in today’s meeting (tbachman, 16:44:31)
* other items (tbachman, 16:44:32)
* ebrjohn added a new section to the SFC wiki — SFC configuration in a
nutshell (tbachman, 16:44:41)
* LINK:
https://wiki.opendaylight.org/view/Service_Function_Chaining:Main#The_SFC_Configuration_in_a_nutshell
SFC in a nutshell on the SFC wiki (ebrjohn, 16:45:24)
* ebrjohn says the IETF hackfest starts this week and continues into
next week (tbachman, 16:46:08)
* ebrjohn says the week after that (July 27th-31st) is the ODL summit
in Santa Clara (tbachman, 16:46:28)
* ebrjohn says he’ll try to host the meeting during the summit, if
it’s feasable (tbachman, 16:48:02)
Meeting ended at 16:49:20 UTC.
