ITU-T J.261 PDF

The objective of this Recommendation is to provide a framework for the implementation of preferential telecommunications services within cable networks as described in [ITU-T J.160] and [ITU-T J.360]. This framework is one of the series of Recommendations addressing these services.

The key aspects of preferential telecommunications services addressed in this framework are priority and authentication. The architectural differences in the two key aspects are addressed in terms of the logical functional entities defined in [ITU-T J.160] and [ITU-T J.360], respectively.

Although this version of the framework addresses the two key aspects, namely, priority and authentication, necessary to support preferential treatment in telecommunications services, other aspects such as policy, traffic engineering, alternate routing, provisioning, etc., are either out of scope or left for future study. As an example, future versions are expected to address provisioning of preferential services for specific users and/or devices (media terminal adapters) at specific locations.
