   Supporting QoS aware Data Delivery in Information Centric Networks
                      draft-anilj-icnrg-icn-qos-00

Abstract

   Information Centric Networking (ICN) is shaping up as an alternative
   networking mechanism for the TCP/IP based host-centric networking
   paradigm.  Content delivery or streaming is one of important use
   cases where the real value and potential of ICN architecture is being
   investigated.  While a number of studies on an optimal and efficient
   routing of Interest requests have been published, more discussion is
   needed on the mechanisms for implementation and enforcement of the
   quality of service (QoS) in the ICN based data delivery path.  In
   this document, we focus on two most popular ICN architectures, CCN
   (Content Centric Networking) and NDN (Named Data Networking) and
   describe how we can achieve the QoS aware data delivery in the ICN
   network.  We propose to use the differentiated services (DiffServ)
   QoS model based on DSCP codes, which is also used in the IP based
   Internet design.  We further present how QoS parameter syntax can be
   added to the current CCNx messages.
