Subject: RE: Our idea for SFC using OpenFlow. RE: [openstack-dev] [NFV][Telco] 
Service VM v/s its basic framework

Vikram,

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

Vikram: The SFC NB API should be independent of where the advanced services are 
deployed, the API should infact hide this information by design.

In the BP, we have proposed an idea of service pool which will be populated by 
the user with their respective advance service instance/s. Our solution will 
just try to find out the best service instance to be used and dictate the flow 
path which the data traffic needs to follow for accomplishing SFC.

Let’s say the service pool contains 2 LB and 2 FW services and the user want a 
SFC as LB-FW. In such scenario a flow rule mentioning the details about LB and 
FW instance with flow path details will be downloaded to the OVS.

Please note the details about the advanced services (like IP details i.e. where 
the service is running and etc) will be fetched from the neutron db.



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 ?

Vikram: If the deployment of advanced services change, the neutron db would be 
updated and corresponding actions (selection of advance service instance and 
corresponding change in OVS dataflow would be done). This is hidden to the user.



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

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
