Open Stack

Vikram,

1.       In this solution it is assumed that all the OpenStack services are available/enabled on all the CNs ?

2.       Consider a  scenario: For a particular Tennant traffic  the  flows are chained across a set of CNs .

Then if one of the  VM (of that Tennant) migrates to a new CN, where that Tennant was not there earlier on that CN, what will be the impact ?

How to control the chaining of flows in these kind of scenario ? so that packet will reach that Tennant VM on new CN ?



Here this Tennant VM be a NFV Service-VM (which should be transparent to OpenStack).

Hi Murali,

We have proposed service function chaining idea using open flow.

Will submit the same for review soon.

Thanks

Hi,
in the IRC meeting yesterday we agreed to work on the use-case for service function chaining as it seems to be important for a lot of participants [1].
We will prepare the first draft and share it in the TelcoWG Wiki for discussion.

There is one blueprint in openstack on that in [2]

Betreff: Re: [openstack-dev] [NFV][Telco] Service VM v/s its basic framework

Hi Murali,

There are many unknows w.r.t ‘Service-VM’ and how it should from NFV perspective.
In my opinion it was not decided how the Service-VM framework should be.
Depending on this we at OpenStack also will have impact for ‘Service Chaining’.
Please find the mail attached w.r.t that discussion with NFV for ‘Service-VM + Openstack OVS related discussion”.


Regards,
keshava

Hi Murali,

    There is already a ServiceVM project (Tacker), currently under development on stackforge:

https://wiki.openstack.org/wiki/ServiceVM

    If you are interested in this topic, please take a look at the wiki page above and see if the project's goals align with yours. If so, you are certainly welcome to join the IRC meeting and start to contribute to the project's direction and design.

Thanks,
- Stephen

Hi keshava,

We would like contribute towards service chain and NFV

Could you please share the document if you have any related to service VM

The service chain can be achieved if we able to redirect the traffic to service VM using ovs-flows

in this case we no need to have routing enable on the service VM(traffic is redirected at L2).

All the tenant VM's in cloud could use this service VM services  by adding the ovs-rules in OVS


Thanks
