Abstract:
Nowadays users consumption style for video and multimedia
applications is strongly changing. Users are heavily counting on
wireless and mobile devices for video streaming and interactive video
and multimedia applications. This can be implemented for instance by
having more intelligence in the service and the network
infrastructure to better suit a differentiated users consumption
style. This can be achieved through having: (i) a knowledge in the
network and service platform about the available device and network
conditions for the end-user and (ii) a knowledge in the network about
the content requirements in terms of devices capabilities and network
resources for content stored either in the network or in the
application server. To obtain such knowledge with no need for
changing the current infrastructure and in a generalized way to all
applications, feedback/notification mechanisms between the end-user
application, the network and the service platform is needed to
provide information helping the content delivery and adaptation
decisions. This document is investigating such application-agnostic
track.
This document extends the Port Control Protocol (PCP) RFC 6887
[RFC6887] to allow: (i) the users application to notify the network
and application server about its available resources in terms of
devices capabilities and network conditions as well as information
about the user (e.g., location, mobility status) and (ii) the
application server to notify the network about the requirements of
the content it stores in terms of devices and network resources. A
new PCP option, denoted the FEEDBACK, is specified to allow such
feedback notification signaling. This option is used with both PEER
and MAP Opcodes.
