[icnrg] comment on draft-kutscher-icnrg-challenges-02

Hi Dirk, Hi all,

I have reviewed draft-kutscher-icnrg-challenges-02. I think that he draft has a good quality and it is usefull. However, I have a comment!

The draft is not discussing any QoS related issues. This might be needed, since NDOs can represent content used in different types of applications. Such applications can be mainly of two types, (1) streaming applications, like VoD, or (2) best effort type of applications, like file distribution and sharing. Each of these two application types impose different QoS requirements on the in-network caching features, i.e., cache placement, content placement, request-to cache routing, provided by ICN.

You might include a paragraph in the Transport Services section. Something like:

The NDOs can represent content used in different types of applications. Such applications can be mainly of two types, (1) streaming applications, like VoD, or (2) best effort type of applications, like file distribution and sharing. Each of these two application types  impose different QoS requirements on the in-network caching features, i.e., cache placement, content placement, request-to cache routing, provided by ICN. Further research is needed on identifying how the above mentioned ICN features can support NDOs used by applications that are demanding QoS support.

Best regards,
Georgios

Abstract:
   This document aims at establishing a common understanding about a set
   of scenarios that can be used as a base for the evaluation of
   different information-centric networking (ICN) approaches so that
   they can be tested and compared against each other while showcasing
   their own advantages.  Towards this end, we review the ICN literature
   and document scenarios which have been considered in previous
   performance evaluation studies.  We discuss a variety of aspects that
   an ICN solution can address.  This includes general aspects, such as,
   network efficiency, reduced complexity, increased scalability and
   reliability, mobility support, multicast and caching performance,
   real-time communication efficiency, energy consumption frugality, and
   disruption and delay tolerance.  We detail ICN-specific aspects as
   well, such as information security and trust, persistence,
   availability, provenance, and location independence.
