       QoS Treatments in ICN using Disaggregated Name Components
                    draft-anilj-icnrg-dnc-qos-icn-02

Abstract

   Mechanisms for specifying and implementing end-to-end Quality of
   service (QoS) treatments in Information-Centric Networks (ICN) has
   not been explored so far.  There has been some work towards
   implementing QoS in ICN; however, the discussions are mainly centered
   around strategies used in efficient forwarding of Interest packets.
   Moreover, as ICN has been tested mainly as an IP overlay, its QoS is
   still governed by the IP QoS framework and there is a need for
   implementing QoS in ICN natively.  This document describes mechanisms
   to classify and provide associated "name-based" extensions to
   identify QoS within the framework of ICN's core design principles.
   The name-based design provides a mechanism to carry QoS information
   and implement the treatments as ICN packets travel across different
   routers in the ICN network.  Detailed discussion is provided for QoS
   specific procedures in each of the ICN network elements i.e.
   consumer, producer, and forwarder.
