This document describes the requirements specification (SRS) for the software infrastructure (or product) that enables the internetworking of Content Delivery Networks (CDNs) through peering, henceforth termed as ‘CDN peering’, and provides an overall description of it. It presents a means for distinct CDNs to coordinate and cooperate with other CDNs, by investigating and developing (a) models for effective internetworking between CDNs though peering; (b) protocols for service delivery in a cooperative environment of CDNs; (c) some concrete examples (technology trends) that exhibits the notion of content networking; and (d) policies for autonomic management of service level through resource negotiation in an on-demand basis. Thus, this document provides a basis for evaluating the proposal for internetworking between CDNs. This is the version 0.1 of the software requirements specification.
