ILNP - Identifier-Locator Network Protocol
This project is enhancing the Internet Architecture by enriching the set of namespaces. The basic approach to this is to deprecate the concept of an Address and replace it with separate Locator and Identifier values. Although the architectural concept is independent of any particular network protocol, our research demonstration will be based on IPv6. Protypes for FreeBSD and Linux are planned.
This work was influenced by Mike O'Dell's prior work on the GSE/8+8 proposal for IPv6 and by work undertaken in the IRTF Namespace Research Group (NSRG), although the current work is different in various ways from those earlier proposals and discussions. In RFC6115 (Feb 2011), the IRTF Routing Research Group (RRG) co-chairs recommended that ILNP be pursued within the IETF.
Although our work is architectural, it is driven by actual problems with the current Internet Architecture (RC4984). For example, a current operational concern addressed by this proposal is the rapid increase in size and in entropy of the Internet routing table, specifically the Default-Free Zone's (DFZ) Routing Information Base (RIB) (RFC4098). It appears that a primary cause for both routing table growth and the increase in entropy is the current method for site multi-homing, which depends on adding extra more-specific prefixes globally for each multi-homed site.
Another example is support for mobile hosts and mobile networks. Mobile systems was not part of the original Interent Protocol design, and so supporting mobility requires additions to IP, as well as treating addresses differently, resulting in inconsistent end-to-end semantics ('home' addresses, and 'care-of' addresses in Mobile IP).
An increasingly important concern is that of security and privacy online. The ILNP architecture can support both (toplogical) location privacy, as well as identity privacy at the network layer.
We believe that ILNP will lead to several specific advantages over the currently deployed Internet Architecture. These advantages include harmoniously integrating various functionality:
- Support for both site and node multi-homing without increasing entropy in the Default-Free Zone (DFZ) Routing Information Base (RIB).
- Native, scalable support for mobile nodes and mobile networks.
- NAT-tolerant networking, by decoupling location from identity.
- IP Security working natively with Multi-Homing, Mobility, and NAT.
- Support for traffic engineering (TE) capability through naming.
- Native support for multi-path transport protocols.
- A simpler, cleaner Networking API for distributed applications.
