Dear All,

We updated the DevOps for Software-Defined Telecom Infrastructures draft to address comments we received from Ramki on the mailing list, and continue the work on some of the sections. A summary of the updates is as follows:
-	Introducing the System Integrator and Customer roles (aligned with comments we received on the mailing list and in previous NFVRG meetings)
-	Advancing the CAP section (aligned with comments we received on the NFVRG mailing list)
-	Further clarifications to the Continuous Integration and Delivery sections
-	New paragraph on Data Virtualization challenges

Comments and suggestions for further improvements are welcome.

Best regards,
-- Catalin

Abstract:
   Carrier-grade network management was optimized for environments built
   with monolithic physical nodes and involves significant deployment,
   integration and maintenance efforts from network service providers.
   The introduction of virtualization technologies, from the physical
   layer all the way up to the application layer, however, invalidates
   several well-established assumptions in this domain. This draft opens
   the discussion in NFVRG about challenges related to transforming the
   telecom network infrastructure into an agile, model-driven production
   environment for communication services. We take inspiration from data
   center DevOps regarding how to simplify and automate management
   processes for a telecom service provider software-defined
   infrastructure (SDI). Among the identified challenges, we consider
   scalability of observability processes and automated inference of
   monitoring requirements from logical forwarding graphs, as well as
   initial placement (and re-placement) of monitoring functionality
   following changes in flow paths enforced by the controllers. In
   another category of challenges, verifying correctness of behavior for
   network functions where flow rules are no longer necessary and
   sufficient for determining the forwarding state (for example,
   stateful firewalls or load balancers) is very difficult with current
   technology. Finally, we introduce challenges associated with
   operationalizing DevOps principles at scale in software-defined
   telecom networks in three areas related to key monitoring,
   verification and troubleshooting processes.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
