The Internet has grown from a small experiment into a collaborative network with more than one billion users. The infrastructure challenges including addressing and routing are being posed by the mobile access and other advanced features , addressing which may require a review of the architecture.Among the design goals of the existing Internet architecture are:
-Connection of existing networks,
-Survivabil ity,
-Support of multiple types of services,
-Accommodation of a variety of physical networks,
-To allow distributed management etc.
These goals were achieved by the core design which includes the :
-L a y e r in g ,
-Packet switching,
-Network of collaborating networks, and
-Intelligent end-systems
The major challenges that face the design of a new internet are:
Security and privacy, Resistance to Distributed Denial of Service (DDoS) attacks, End-to-end QoS/QoE, Mobil ity, R el iabi l ity, Addressing and identity etc. For this, the research is being channelised into these areas like:
-Flow-based routing and switching,
-Dynamic circuit switching,
- Backbone redesign, etc.
