FLAT ADDRESS AND MOBILITY FIRST

"New features like mobility, multi-homing, security and inter-networking among heterogeneous network domains are challenging the current Internet architecture. The service offered today, provides end-to-end communication using a global and hierarchical addressing space , i.e., unique IP address for both localization and identification functions. A common view present in the current literature is that an homogeneous inter-networking protocol as represented today by the IP protocol is no more convenient for supporting the introduction of new services.Requirements for mobility and security emphasize the need of a new inter-networking architecture."

The main points to make a new approach for the Internet architecture viable are

• Separation of identity and localization
• The creation of overlay networks for introducing new control plane
  • Address Allocation
  • Routing
  • Name Resolution
• The adoption of new routing strategies for these overlay networks

MOBILITY FIRST

GNRS (Global Name Resolution Service)-To address the separation of identity and location

Each node in the network shall be assigned a GUID (Globally Unique ID), that shall serve as the address of the node. This GUID is associated with current network reachability information of the node This serves to separate addressing from location, assisting is support for mobility GNRS functionality is attained using Distributesd system ( DHT)
