Re: [Netconf] [Rtg-yang-coord] [netmod] Requirements for I2RS protocol and I2RS interim (6/24/2015 at 10:00 - 11:30am ET)

["Eric Voit (evoit)" <[e-mail]>]

I presented PubSub ‘-01’ requirements in NETCONF at IETF 92.    Changes in ‘-02’ are likely not enough for a speaking slot.

What might be interesting for a NETCONF speaking slot is an analysis of what requirements from “draft-ietf-i2rs-pub-sub-requirements” are met by “draft-clemm-netconf-yang-push”.   (During IETF 92, NETCONF reviewed draft-clemm. There was a strawman poll (12 yes, 0 no) where the WG indicated interest.)

Would NETCONF want Alex or I to speak on a requirements-to-technology comparison in Prague?

Mahesh:

Ok.  I thought you were going to review the requirement documents and give I2RS an initial guess.  We have present these at 3 I2RS interims, and the slides are online.  I will send the minutes to the netconf working group for their review.

The presentation of the requirements will need the following time:


1)      10 top requirements – 5-10 minutes [Sue Hares]

2)      Ephemeral state – 15 minutes [Jeff Haas]

3)      Pub/sub requirements – 10-15 minutes [Eric Voit]

4)      Traceability [ 10-15 minutes]

5)      Security [10 minutes] [Sue Hares and Joel Halpern]

6)      Review of I2RS models [5 minutes]

7)
If you have heard pub/sub and traceability requirements, you may delete this from timeline.

Susan,

The NETCONF WG acknowledges the receipt of the requirements.

These requirements need to be discussed in front of the NETCONF WG. Would suggest that i2rs WG present these requirements in front of the NETCONF WG during IETF 93 in Prague to kick start discussion within the WG. Please let us know how much time you (or someone from i2rs) would need to present the requirements.

Thanks.

Netconf Working Group:

The I2RS WG would like to pass you a set of requirements for the I2RS protocol, and asks that you provide an analysis by IETF 93 on whether NETCONF or RESTCONF can meet these requirements.   We expect that these requirements may require changes to the either NETCONF or RESTCONF.

The I2RS architecture document (draft-ietf-i2rs-architecture-09<https://datatracker.ietf.org/doc/draft-ietf-i2rs-architecture/>) provides a high-level overview of the I2RS  protocol.  The I2RS has compiled the following documents to provide the additional details on the requirements for the protocols.

1)      draft-ietf-i2rs-ephemeral-state-00<https://datatracker.ietf.org/doc/draft-ietf-i2rs-ephemeral-state/>
2)      draft-ietf-i2rs-pub-sub-requirements-02<https://datatracker.ietf.org/doc/draft-ietf-i2rs-pub-sub-requirements/>
3)      draft-ietf-i2rs-traceability-03<https://datatracker.ietf.org/doc/draft-ietf-i2rs-traceability/>

The draft-ietf-i2rs-ephemeral-state-00 contains the results of the discussion from the 6/10 interim and the top 10 requirements for I2RS.  In addition, the draft-ietf-i2rs-ephemeral-state-00 contains an set of detailed requirements on how the I2RS WG sees the I2RS protocol operating.  These detailed requirements are to be seen as suggestions on what type of solution the I2RS WG would like to see, but I2RS WG is asking the NETCONF WG to provide its best designed protocol.  Please note as part of these detailed requirement the draft-ietf-i2rs-ephemeral-states-00 contains the idea of using metadata to record secondary identity.

The I2RS protocol is driven by data-models.  The approved data models for protocol independent services are:
-          draft-ietf-i2rs-rib-data-model-00<https://datatracker.ietf.org/doc/draft-ietf-i2rs-rib-data-model/>
-          Filter-Based RIBS:  draft-kini-i2rs-fb-rib-data-model.00 (released later this week)
-          Topology model which is a composite of:
o   Generic topology model: draft-ietf-i2rs-yang-network-topo-01<https://datatracker.ietf.org/doc/draft-ietf-i2rs-yang-network-topo/>
o   L3 topology model: draft-ietf-i2rs-yang-l3-topology-00<https://datatracker.ietf.org/doc/draft-ietf-i2rs-yang-l3-topology/>
o   L2 topology model: draft-ietf-i2rs-yang-l2-network-topology-00<https://datatracker.ietf.org/doc/draft-ietf-i2rs-yang-l2-network-topology/>
o   L1 Topology model: draft-zhang-i2rs-l1-topo-yang-model-01 (-02 released later this week).
o   Service topology model: draft-hares-i2rs-service-topo-yang-model-00 (released on Wednesday)

At this time, none of the Topology models utilize Traffic engineering.  It is anticipated that these models will support traffic engineering.  Estimated rates of transfer and timing requirements for these modules are at: http://trac.tools.ietf.org/wg/i2rs/trac/wiki - under the protocol requirements table.

We hope that NETCONF WG can provide some initial feedback on these requirements by IETF 93 at the Tuesday I2RS session.   I2RS will use the 6/24 interim at 10:00-11:30am ET  to provide a time for any participate in the I2RS, netconf, or netmod group to ask additional questions on these requirements.
