New Architecture for The Future Internet

New Architecture for The Future Internet

• Joon-Suk KANG

2
Purpose

• Network Diversification
• Identifier/Locator separation

3
Network Diversification

• Network Pluralism
• Can one common network architecture (such as IP)
  meet the various demands of future Internet?
• Various terminal types
• Sensor node Super computer
• Heterogeneous different in kind services
• Future Internet needs to support network diversity

4
Network Diversification

• Future Internet Combination of various and
  heterogeneous networks
• Each network has the most proper protocol
• Each protocol may have different location method
  (location type as well)
• No common network layer

Network Diversification

• Terminology
• NG(Network Group)
• A collection of nodes and links that are under a
  common network technology and administration
• NG context
• A basic information set of NG
• Address, packet format, transport protocol
• GW(Gateway)
• A gateway between two different networks
• Perform locator type
• Assumption
• Each node has globally unique ID NID
• Each NG has globally unique ID GID
• Each GW knows the topology of the internet of NGs
• Using link-state-like protocol

Network Diversification

• Simple protocol suit

Naming Service within Same NG

• HIP(Host Identity Protocol)
• DNS/RVS(Rendezvous Server)

Problem

• Heavy lookup overhead
• How to get the information about loc-id mapping
  from other NGs
• How to forward the packets to the destination in
  other NG
• Source routing??
