Abstract
Handling mobility at the transport layer is a promising
approach to achieve seamless handover in the context of heterogeneous
wireless access networks. In particular, features such
as multihoming and dynamic address reconfiguration provided by
mobile SCTP (mSCTP) protocol are among the key enablers for
handover support at the transport layer. This paper investigates
the applicability of Concurrent Multipath Transfer (CMT) to distribute
data among two end-to-end paths of a mSCTP association
during handover transition process. To that end, the principles of
the mSCTP-CMT design are given, emphasizing the consequences
of such a sender-introduced reordering and its congestion control
implications in a handover scenario. The proposed mSCTP-CMT
handover scheme is benchmarked with a pure mSCTP handover
scheme. Provided analysis indicates the possible application
area of mSCTP-CMT, taking into account not only handover
scenario parameters (dwelling time, available bandwidth ratio
and round-trip time), but also the most important constraint
of such a design: receiver buffer (rbuf) size. Rbuf size proves
to be the major limiting factor shrinking significantly possible
mSCTP-CMT application scope, yet not excluding definitively
the proposed idea.
