ITU-T Y.2057 PDF

Recommendation ITU-T Y.2051 defines a new term, "IPv6-based NGN", to support advanced architectural objectives of the next generation network (NGN) by using IPv6 protocols and mechanisms. Recommendation ITU-T Y.2015 describes general requirements for identifier and locator separation (also known as ID/LOC separation) to efficiently support mobility, multihoming and host renumbering in the NGN.

In order to enrich the IPv6-based NGN with the benefits of ID/locator separation, this Recommendation describes a framework of ID/LOC separation in the IPv6-based NGN.

The scope of this Recommendation includes:

– IPv6 addressing schemes for ID/LOC separation

– mapping functions and procedures for ID/LOC separation in IPv6-based NGNs

– considerations of deployment for ID/LOC separation in IPv6-based NGNs.
