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
Use cases |
Along with above mentioned points, we may also want to look at the use cases that might guide us in design process
- MULTI-HOMING
This refers to the scenario where-in the end device may come with multi-home capability i.e., interfaces for different technologies on same device . This implies a requirement to support dual interface.
Q
- Do we need "Multi-homed" gateways for -
- Address Translation and
- Protocol Translation between two domains
MOBILITY FIRST |
1. 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 unique identity of the node.
- This GUID is associated with current network reachability information of the node
- This serves to separate addressing from location => support for mobility
- GNRS functionality is attained using Distributed system ( DHT)
Q
- Who assigns these GUID ?
- Levels of GNRS required ? => Only Local and Global ?
- Is this a service of control plane ?
2. Routing
