01-028: Wireless Network Label Switched Packet Transfer

The Advanced Internet Laboratory at George Mason University has developed a wireless network Label Switched Packet Transfer (LSPT), which provides a hierarchical architecture to use label switching to support wireless mobile terminals.

This architecture provides for efficient packet transfer over mobile wireless networks by efficiently allocating wireless resources.

- Is a framework for flexible support of features such as quality of service.
- Interconnects to the backbone of a network with minimal requirements at the mobile terminal.
- Provides efficient mechanisms for location and handoff management.
- Accommodates service differentiation in a cellular network.
- Reroutes without affecting traffic, yielding no adverse impact on the network.
- Supports multiple radio links between a wireless mobile terminal and a multiplicity of base stations.
- Uses multi link techniques and mobility techniques to affect an efficient network admission policy
- Provides forwarding mechanisms and limited broadcasting of reach ability information which may be used in managing and routing the communications packets through the wireless mobile network.

Market Significance:
The telephone industry has an urgent need for an architecture that allows mobile terminals to be interconnected to a backbone network with minimal requirements on mobile terminals for existing and future Internet and multimedia services. The industry needs mechanisms for location and handoff management as well as label merging capability and fast rerouting schemes to support multilink techniques and mobility.
