Summary:
|
This Recommendation specifies signalling requirements and protocols for request routing by describing the relevant gap analysis of the existing protocols, emerging challenges and their impacts, new capabilities, and operational procedures.
The capabilities of request routing are identified and defined by considering chunk-based content delivery, application-layer traffic optimization, name-based request routing, and in-network content caching, whose principles are content-awareness and context-awareness as defined in [ITU-T Y.sun-cdf] and [ITU-T Y.sun-context], respectively.
