Subject: [CDNi] Discussing "Adaptive Streaming" more in cdni-framework

Bruce, Larry,

I just wanted to pass on a suggestion made during the WG session.

From talking to people this week, it became clear to me that:
	* just about everyone expects a CDNI mesh to support content delivery via HTTP Adaptive Streaming
	* people have different expectations about how CDNI supports this.

So my suggestion is that the framework very explicitly addresses this question (perhaps even as a standalone section, so people can easily find the discussion on that specific question). In line with the general current approach of the framework, the expectation would not be that the framework mandates a given approach, but explores the design spaces, and helps analysis and converging on if/what CDNI interfaces need to support something specific for adaptive.
A few aspects that come to mind are:
	* Request Routing: should/can request routing be performed more efficiently than once per segment?
	* Acquisition: should/can acquisition be performed on a per-segment basis or differently?
	* Logging: the framework already brings up the point about logging for adaptive in section 4.3  
	* Metadata: is any specific metadata required.

Can you consider expanding the discussion on adaptive streaming in the next rev?

Thanks

Francois
