Abstract:
Nowadays users consumption style for video and multimedia
applications is strongly changing. Users are consuming content
through multi-screen and are heavily counting on wireless and mobile
devices for video streaming and interactive video and multimedia
applications. This necessitates more intelligence in the service and
the network infrastructure to better suit a differentiated users
consumption style, which 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.
