ABSTRACT
Networking of Information (NetInf) is an information centric networking paradigm that
can support cloud computing by providing new possibilities for network transport and
storage. It offers direct access to information objects through a simple API, independent
of their location in the network. This abstraction can hide much of the complexity of
storage and network transport systems that cloud computing today has to deal with. In
this paper we analyze how cloud computing and NetInf can be combined to make cloud
computing infrastructures easier to manage, and potentially enable deployment in
smaller and more dynamic networking environments. NetInf should thus be understood
as an enhancement to the infrastructure for cloud computing rather than a change to
cloud computing technology as such. To illustrate the approach taken by NetInf, we also
describe how it can be implemented by introducing a specific name resolution and
routing mechanism.

INTRODUCTION
The topic of Cloud Computing is gaining more and more attention in the service
research community. The main idea is to make applications available on flexible
execution environments primarily located in the Internet.

INTRODUCTION

Architecture Overview

Conclusion
In this paper we have presented the NetInf architecture, and described how it can
support cloud computing services by offering an API that hides the dynamics of object
locations and network topologies. One single name resolution and routing mechanism is
used, regardless of whether the dynamics depend on network reconfigurations, change
of service level agreements, mobility events, re-homing events, or any other type of
network event. The task of designing cloud computing services that are robust against
object re-locations or changes in the topology of the underlying infrastructure network
can thereby be significantly simplified.
To illustrate the NetInf approach, a novel routing mechanism based on late locator
construction has been described that performs object-to-object routing rather than
traditional host-to-host routing. This mechanism can operate over a highly dynamic
network topology and allows for scalable handling of a very large number of objects.
