Background




The Internet was designed in the 1960s to
dispatch data to fixed addresses of static PCs.
But today it connects a riot of diverse
gadgets that can zip from place to place and
connect to many different networks.
As the underlying networks have been
reworked to make way for new technologies,
some serious inefficiencies and security
problems have arisen.
As a result, Over the
past
years,
fundamentally new network designs have
taken shape and are being tested.

Several proposed
solutions for Future Internet
 SDN:
Software-Defined Networking
 Self Organizing & Autonomic Networks
 Network resources and policy controller
 Network Virtualization & slicing
 Cloud Network & Network as a Services
 Information-Centric Networks/ Content
Centric Network

Software Defined
Networking(SDN)

[

SDN is considered a major shift in networking
which is evolved from work done at UC Berkeley
and Stanford University in 2008.

SDN is promoted by the New initiative ONF and
recently by ITU-T SG 13 Future Networks and
Under discussion at IETF

SDN allows operators to use of centralized,
programmable control-plane and data-plane
abstraction, where control and data planes are
separated.

SDN gives operator ability to control/manage
virtualized resources and networks without
requiring new hardware technologies.

Network Function
Virtualization

Network Functions Virtualization aims to
transform the way that network operators
architect networks.

By
evolving
standard
IT
virtualization
technology to consolidate many network
equipment types onto industry standard high
volume servers, switches and storage, located
in Data centers, Network Nodes and in the end
user premises.[2]

Automatic Network
Architecture(ANA)

The ultimate goal of ANA is to design and
develop a novel network architecture that
enables flexible, dynamic, and fully autonomic
formation of network nodes as well as whole
networks.

Self-Organizing Networks SON, (3GPP)

Main functionalities:
 Self-Configuration (Plug & Play of new
eNodeB)
 Self-Healing(e.g.Cell Outage Compensation)
 Self-Optimization(eg.
Mobility
Load
Balancing, Handover Optimization, Energy
Saving Management, etc.)

Information Centric
Networking(ICN)

ICN
focus on data, rather than physical
location of the data from where that data is to
be retrieved from.

Principal
paradigm
is
not
end-to-end
communication between hosts - as it is in
current Internet architecture.

Publish- Subscribe model with more power to
the subscriber

In-network storage/ use Content router (CR) ;
efficient communication through replication.

Provide better mobility support, Energy efficient
and more security than current architecture

Summary



The Internet is straining to meet demands that
its design never anticipated, such as supporting
billions of mobile devices and transporting huge
amounts of multimedia content.
Future networks will be the infrastructure which
connects the future Internet of people, content,
clouds and things
Now lets see, which network design offers what
benefits, and is that design is the best way to
achieve those benefits? And the answer of this
fundamental question will decide Who's going to
win the race of future network architecture?
