System for Subnet Relocation

  
File # 3308 
Description

ISI / USC Researchers have developed a system for dynamically relocating Internet subnets. This system can securely relocate portions of a network to a location remote from the original network via an automation process for configuration and management, using a graphical interface and multipoint control channel to manage overlay deployment at the IP layer. An anchor site can provide a delegated IP address block and reverse DNS as a rented service, and with this technology, a remote site can use those IP addresses with the same privileges.

Advantages
  • Provides true Internet service - globally routable IP addresses, with forward and reverse DNS - supporting services on well-known ports.
  • Works behind NATs - provides Internet service for any IP-based protocol, even those defeated by NATs, including experimental protocols.
  • Works behind varying dynamic IPs - enables stable connectivity even where DHCP leases are short and rotated, without timeout delays or protocol failures.
  • Provides IPsec-encrypted IPv4, multicast IPv4, IPv6, and multicast IPv6 - all behind NATs or conventional IPv4.
  • Works for any IP client: Unix, Windows, Mac, PDAs, embedded systems, etc., with plug & go and no additional support needed. 
Applications
  • Enable use of any IP client (PC, PDA, etc.) and protocol.
  • Provide true Internet connectivity at conferences, exhibitions, and demos at a customer site, remote office, residence or hotel.
  • Support experiments and testbeds.
  • Provide stable and secure true Internet VPN without specific client support.
  • Reuse office Internet address space - enables reuse of even small blocks.
  • Community service: rent small blocks "at cost" to researchers, students.
