Abstract
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 an
mSCTP association during the handover transition process. To
that end, the principles of the mSCTP-CMT design are given,
emphasizing the consequences of a sender-introduced reordering
and its effect on congestion control. The proposed mSCTPCMT
handover scheme is benchmarked with two other handover
schemes, namely mSCTP and SCTP failover-based. 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 an important design constraint: receiver buffer (rbuf)
size. Rbuf size proves to be a major limiting factor shrinking
significantly, yet not excluding mSCTP-CMT’s application scope
