standardization of data aware networking (DAN). Detailed requirements and their degree ("required",
"recommended", or "optional") need further study.

6 Introduction
[ITU-T Y.3001] defines four objectives and twelve design goals which reflect the new emerging requirements
for FNs. One of the objectives is data awareness which allows FNs to have mechanisms for promptly retrieving
data regardless of their locations. Recently, this concept has been paid much attention in the network R&D
community under the name of information centric networking (ICN) [b-Dannewitz] [b-Jacobson] [b-Sarela]
because data acquiring would be more efficient with this technology, and the concept itself would change
the current network architectures drastically. This Recommendation therefore specifies the framework of
data aware networking (DAN) for FNs.

A major Internet usage today is the retrieval of data whose amount has been changing in an explosive
manner. For instance, the sum of all forms of video (TV, video on demand, Internet, and P2P) would continue
to be approximately 90% of global consumer traffic by 2015 [b-Cisco]. Social networking services are also
creating huge volumes of blog articles instantaneously, ubiquitous sensor networks [ITU-T Y.2221] are
generating massive amount of digital data every second, and some applications called "micro-blogs" generate
quasi-real-time communication that includes multimedia data [ITU-T Y.3001]. Since this trend is likely to be
