Locator/Identifier Separation Protocol
An IP address has two roles now.
- The identifier of the partner. I distinguish the network interface uniquely in a local network
- An identifier for routing. I tell where the network interface is connected to in large-scale routing
Some methods to let you separated two roles and scale the Internet more have been suggested. Locator/Identifier Separation Protocol (LISP) and GSE/8+8, solution to host side include SHIM6 or Host Identity Protocol (HIP) as solution to network side.
In Locator/Identifier Separation Protocol, I take the role that an element (router) constituting a network maps individual identifier (EID) and position identifier (RLOC) onto. I cannot see the processing from an end host.
Superiority of LISP
- Cheap multi-homing not to depend on BGP and AS number, PI address
- Crossing of the address family: From IPv6 from IPv6 over IPv4 and IPv4 IPv4 over IPv6
