2. Allows the following benefits for end-users, with the
needs of larger organisational end-users being most
important, but in principle extending to individual
end-users's networks and single devices. These benefits
should support communications initiated by hosts in
networks which have not adopted the new architecture -
perhaps not with the same efficiency as to non-upgraded
networks, or with as high an efficiency as between two
hosts in upgraded networks. Hosts in non-upgraded
networks should suffer no loss of reliability in their
communications with hosts in networks using the new
architecture.
A. Portability of the address space when choosing
another provider.
B. Multihoming with two or more providers, with
robust session continuity.
C. Incoming Traffic Engineering where there are two
or more links to providers. This TE should be
technically capable of being controlled by the
end-user and/or the provider.
4. Provides meaningful benefits to the parties who bear the
costs of deploying and maintaining the existing and new
elements of the routing system.
