Implementation Issues

Implementation Issues

• Lightweight signaling
• FSP location and migration
  • Switch, Base, ATM Host, ATM cell-relay
  • FSP movement similar to handover
• Distributed Management entities
  • RPC communication provides location independence
• Handover Signaling VC
  • Fast handover completion
• Virtual Path implementation
  • Use Virtual Virtual Paths using tunneling

FSP can be located in a switch, base-station or ATM host.

• Switch - most efficient
• Base least trouble base has
• ATM host compromise - switching performance limited
• ATM cell-relay - two port switch.

The most efficient place is within an ATM switch, but access to the software in the switch is required.
