Subject: Re: [Openstack] Network Service for L2/L3 Network
Infrastructure blueprint
Hi, all
As we have said before, we have started designing and writing
POC codes of network service.
- I know that there were several documents on the new network
service issue that were locally exchanged so far.
Why not collecting them into one place and share them
publicly?
Based on these documents, I created an image of
implementation (attached). And I propose the following set of
methods as the generic network service APIs.
- create_vnic(): vnic_id
Create a VNIC and return the ID of the created VNIC.
- list_vnics(vm_id): [vnic_id]
Return the list of vnic_id, where vnic_id is the ID of a VNIC.
- destroy_vnic(vnic_id)
Remove a VNIC from its VM, given its ID, and destroy it.
- plug(vnic_id, port_id)
Plug the VNIC with ID vnic_id into the port with ID
port_id managed by this network service.
- unplug(vnic_id)
Unplug the VNIC from its port, previously plugged by
calling plug().
- create_network(): network_id
Create a new logical network.
- list_networks(project_id): [network_id]
Return the list of logical networks available for
project with ID project_id.
- destroy_network(network_id)
Destroy the logical network with ID network_id.
- create_port(network_id): port_id
Create a port in the logical network with ID
network_id, and return the port's ID.
- list_ports(network_id): [port_id]
Return the list of IDs of ports in a network given its ID.
- destroy_port(port_id)
Destroy port with ID port_id.
This design is a first draft.
So we would appreciate it if you would give us some comments.
In parallel with it, we are writing POC codes and uploading
it to "lp:~ntt-pf-lab/nova/network-service".
Thanks,

Hi, all
We, NTT PF Lab., also agree to discuss about network service at the
Diablo DS.
However, we would really like to include network service in
the Diablo
release because our customers strongly demand this feature. And we
think that it is quite important to merge new network
service to trunk
soon after Diablo DS so that every developer can contribute their
effort based on the new code.
We are planning to provide source code for network service
in a couple
of weeks. We would appreciate it if you would review it
and give us
some feedback before the next design summit.
Ewan, thanks for your making new entry at wiki page (*1).
We will also
post our comments soon.

I will collect the documents together as you suggest, and
I agree that we need to get the requirements laid out again.
Please subscribe to the blueprint on Launchpad -- that way
you will be notified of updates.

Thanks,

Hello,
We, NTT DATA, also agree with majority of folks.
It's realistic shooting for the the Diablo time frame to have the
new network service.
Here are my suggestions:
- I know that there were several documents on the new network
service issue
that were locally exchanged so far.
Why not collecting them into one place and share them
publicly?
- I know that the discussion went into a bit
implementation details.
But now, what about starting the discussion from the
higher level
design things (again)? Especially, from the
requirements level.
Any thoughts?

You are correct, the networking service will be more
complex than
the
volume
service. The existing blueprint is pretty comprehensive,
not only
encompassing the functionality that exists in today's network
service
in
Nova, but also forward looking functionality around flexible
networking/openvswitch and layer 2 network bridging
between cloud
deployments.
This will be a longer term project and will serve as the bedrock
for
many
future OpenStack capabilities.

Here is the suggestion. It is clear from the response
on the list
that
refactoring Nova in the Cactus timeframe will be too risky,
particularly as
we are focusing Cactus on Stability, Reliability, and
Deployability
(along
with a complete OpenStack API). For Cactus we should leave the
network and
volume services alone in Nova to minimize destabilizing the code
base. In
parallel, we can initiate the Network and Volume Service
projects
in Launchpad and allow the teams that form around these
efforts to
move
in
parallel, perhaps seeding their projects from the
existing Nova code.
Once we complete Cactus we can have discussions at the Diablo DS
about
progress these efforts have made and how best to move
forward with
Nova
integration and determine release targets.
I agree that there is value in starting the proof-of-concept work
around
the network services, without sacrificing too many developers to
it,
so
that a good plan can be presented and discussed at the
Diablo Summit.
If volume sounds relatively simple to me, network sounds
significantly
more complex (just looking at the code ,network manager code is
currently used both by nova-compute and nova-network to
modify the
local
networking stack, so it's more than just handing out IP
addresses
through an API).
