A method and apparatus to support a hierarchical architecture which
integrates wireless mobile terminals into networks such as the Internet.
This architecture provides for efficient packet transfers over mobile
wireless networks by efficiently allocating wireless resources. Label
Switched packet forwarding facilitates traffic engineering and
internetworking by attaching short fixed length labels to communications
packets at an entry node to a wireless network to provide an efficient
path to an exit node of the same wireless network. Forwarding mechanisms
and limited broadcasting of reachability information are used in managing
and routing the communications packets through the wireless mobile
network. The present invention also supports multiple radio links between
a mobile and a multiplicity of base stations. Multi-link techniques are
used to affect an efficient packet transfer and admission policy.
