Vertical handoff is the key technology supporting session mobility in the future heterogeneous network environments. Based on the asymmetry feature of vertical handoff, this paper analyzes the handoff procedure of MIPv6 and mSCTP in forced and unforced handoff scenarios. Qualitative and quantitative analysis and comparison of the handoff performance including handoff delay, handoff packet loss and signaling overhead are given accordingly. Besides, the main factors influencing vertical handoff performance are pointed out and possible performance improvement schemes are discussed.
