Optimization of Packet Forwarding
nTriangular Routing
–sender sends all packets via HA to MN
–higher latency and network load
n“Solutions”
–sender learns the current location of MN
–direct tunneling to this location
–HA informs a sender about the location of MN
–big security problems!
nChange of FA
–packets on-the-fly during the change can be lost
–new FA informs old FA to avoid packet loss, old FA now forwards remaining packets to new FA
–this information also enables the old FA to release resources for the MN
