A content network is an architecture of network elements, arranged for efficient delivery of digital content. Such content includes, but is not limited to, web pages and images delivered via HTTP, and streaming or continuous media which are controlled by RTSP.
The working group will first define requirements for three modes of content internetworking: interoperation of request-routing systems, interoperation of distribution systems, and interoperation of accounting systems. These requirements are intended to lead to a follow-on effort to define protocols for interoperation of these systems.
In its initial form, the working group is not chartered to deliver those protocols, but we encourage individual submission of internet-drafts describing protocols intended to meet the evolving requirements. We anticipate rechartering of the working group to specify protocols, after the requirements documents are stable and rough consensus emerges about the number and relationship of such protocols.
In addition to defining requirements, the working group will develop a number of supporting documents. These documents are: a shared vocabulary for the problem domain, scenarios, an overall architecture for interoperation, and a summary of request-routing mechanisms currently in use. The total expected deliverables are as follows, including the current draft corresponding to each:
1. Vocabulary
