Performance Improvements of Mobile SCTP During Handover Period
Handling mobility at the transport layer is an interesting approach to attain seamless handover in the context of heterogeneous access networks. To support terminal mobility, an extension of SCTP called SCTP-DAR (SCTP Dynamic Address Reconfiguration) (a.k.a. mobile SCTP) has been defined allowing SCTP endpoints to update IP address and inform the remote peer about primary address change. However, mobile SCTP suffers from performance degradation during handover. In this paper, the authors investigate two handover-related issues: reduction of data rate immediately after handover and packet reordering.
