Short Abstract :
Networking of information (NetInf) is an information-centric approach to the network of the future that is 
being explored in the FP7 project 4WARD1. In this approach, it is the information objects themselves 
which are the primary focus rather than the network nodes. Communication is performed in terms of 
requesting and delivering named information objects. The hosts or nodes of the network is secondary. 
Any node holding a copy of the information can provide it to a requester. Storage for caching these 
copies of information become an integral part of the network. This approach is believed to result in a 
network that  is  better  suited for  content  distribution,  the currently  prevailing use of  communication 
networks.  The  PARC Content  Centric  Networking  (CCN)2 and  the  Publish-Subscribe  Internet  Routing 
Paradigm (PSIRP)3 are two other projects also taking an information-centric approach for designing a new 
network.
A fundamental part of the NetInf network architecture is the information object naming scheme. It names 
pieces of information independently of where they are stored. The scheme has direct support for content 
integrity and author authentication. This means that the receiver of an information object can verify the 
data integrity and the identity of the originator without needing to trust the particular network node or 
server that delivered the information. This is an important property needed to implement the vision of 
information-centric  networking.  Another  important  component  of  an  information-centric  network 
architecture is the function which enable locating a copy of an information object when it is requested by 
someone. The NetInf architecture defines a name resolution system using an integrated approach that 
routes information by its name called MDHT – Multiple DHTs.
A prototype of a NetInf network including a set of example applications is under development. A version 
was demonstrated at the IEEE LCN conference in October 2009. The software is currently in the process 
of being made available as open source.
For information centric  networking to become the next main networking paradigm standardization is 
required in a number of areas, which include: naming of information objects, name resolution, protocols 
for publishing and retrieving objects, standards and legal frameworks for how objects can be cached. 
New or modified protocols for routing, management and accounting will also be needed.
