Neutron Services Insertion, Chaining, and Steering

Registered by Sumit Naiksatam on 2013-03-10

In Havana we took a significant step forward with addition of multiple advance network services. Currently we have support for FWaaS, LBaaS, and VPNaaS. However the association of these services with other neutron constructs either happens implicitly or to a virtual router. In other words there is no generic service insertion mechanism to facilitate L3, L2, bump-in-the-wire, and tap insertion modes. Moreover, with more than one service it becomes relevant to explore the model of how multiple services can be requested and sequenced in a chain.

Whiteboard

August-22 (mestery): This is an umbrella BP with no code, moving out of Juno to clean things up per discussion with ttx last week.

15-July (mestery): Moving this to Juno-3 as this is the umbrella BP and has no code associated with it.

27-May (mestery): Moving to Juno-2, this is unlikely to land in Juno-1.

6-Mar (markmcclain): Deferring to Juno

Sumit (Dec-13) - Updated the google doc based on feedback during the summit, and per discussion with Nachi. Major change, not modeling the insertion_context as a separate resource, but as an attribute for each logical service instance.

Sumit (Feb 19): currently the service context insertion is being addressed. Service chain will be a follow up patch but won't make it for Icehouse3
