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 Legal entity: Ericsson AB, registered office in Stockholm. This Communication is Confidential.

Name: draft-unify-nfvrg-devops Revision: 04 Title: DevOps for Software-Defined Telecom Infrastructures Document date: 2016-03-20 Group: Individual Submission Pages: 24 URL: https://www.ietf.org/internet-drafts/draft-unify-nfvrg-devops-04.txt Status: https://datatracker.ietf.org/doc/draft-unify-nfvrg-devops/ Htmlized: https://tools.ietf.org/html/draft-unify-nfvrg-devops-04 Diff: https://www.ietf.org/rfcdiff?url2=draft-unify-nfvrg-devops-04 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. The IETF Secretariat
