        Title           : Considerations in the development of a QoS Architecture for CCNx-like ICN protocols

   This is a position paper.  It documents the author's personal views
   on how Quality of Service (QoS) capabilities ought to be accommodated
   in ICN protocols like CCNx or NDN which employ flow-balanced
   Interest/Data exchanges and hop-by-hop forwarding state as their
   fundamental machinery.  It argues that such protocols demand a
   substantially different approach to QoS from that taken in TCP/IP,
   and proposes specific design patterns to achieve both classification
   and differentiated QoS treatment on both a flow and aggregate basis.
   It also considers the effect of caches in addition to memory, CPU and
   link bandwidth as a resource that should be subject to explicitly
   unfair resource allocation.  The proposed methods are intended to
   operate purely at the network layer, providing the primitives needed
   to achieve both transport and higher layer QoS objectives.  It
   explicitly excludes any discussion of Quality of Experience (QoE)
   which can only be assessed and controlled at the application layer or
