Bhumip, Thanks, I'm aware of this draft. We should discuss it on the SOP alias as not to clutter everyone's email with a topic that may not be of interest. I'm cross posting this to SOP alias for now. One of things that the first draft describes is limitations of HTTP (and by implication web-services) for doing cloud - HTTP does not have constructs to do service discovery, pub-sub, commit-cancel, transaction forking, interactive prompts, etc. These capabilities are service-independent (applicable to all services) and very important to build complex, multi-tiered, or cross-domain services. So, we did not want to add just a new content-type to HTTP, and layer basic capability into the controller application. The idea here is that if there are service independent capabilities, they should be part of a basic protocol scheme, which can be used by every type of service. But we preserved the text-based nature of well-known L7 protocols - SIP, HTTP, SMTP, etc. To the specific issue of broker, you might want to refer to the architecture draft, where we described different types of brokers (we call them proxies). The functionality in the broker differs depending on where you place the broker - in the service edge, customer edge, provider edge, etc. We expect that different domains (compute, storage, network ..) will have different domain controllers. You still need to find an interoperable scheme to stitch these domain controllers.

We have a few drafts posted on a "Service Orchestration Protocol", with the intent to enable cloud interoperability. http://tools.ietf.org/html/draft-dalela-orchestration-00 - talks about why we need a protocol, a.k.a. requirements http://tools.ietf.org/html/draft-dalela-sop-architecture-00 - describes the use-cases and network deployments with the protocol http://tools.ietf.org/html/draft-dalela-sop-00 - describes the protocol's messages http://tools.ietf.org/html/draft-dalela-sdf-00 - describes scheme for service naming, workflows, etc. http://tools.ietf.org/html/draft-dalela-sop-flows-00 - describes some message flows A discussion alias https://www.ietf.org/mailman/listinfo/sop is setup for you to participate in case you find it interesting. Thanks and look forward to discussing there. -Ashish _______________________________________________ dc mailing list dc@ietf.org https://www.ietf.org/mailman/listinfo/dc
