Abstract

Software-defined networks (SDN) will be important in the future Internet. Measurements and analyses show the current SDN mobility management problems including long packet delays during handoff and considerable control overhead for supporting the mobility. The packet delay and control overhead are reduced by a fast mobility management scheme which uses tunnel and flow tables to decrease the communication between the control plane and the data plane. Simulations show that the fast IP mobility management scheme reduces the packet delay ten folds compared with the current SDN mobility management scheme with the control overhead during user handoff reduced by more than half.

Key words

software-defined network / mobility management / delay / controlling overhead
