Adaptive Primary Path Switching for SCTP Handover

This paper proposes a primary path switching scheme for SCTP handover, in which a mobile terminal switches its primary path to an alternate path adaptively by using the round trip times (RTTs) of the paths measured in the network. From the experiments we see that a conservative switching scheme is preferred in the network where the gap of RTTs of the candidate paths is small, whereas an aggressive scheme is reasonable in the network with a large gap of RTTs.
