Multipath Communication over Terrestrial and Satellite Links

Multipath communication with heterogeneous channels is very challenging. In this paper, we describe the combination of terrestrial and satellite internet access links. We review related concepts for such a setup (MPTCP, CMT-SCTP, MPQUIC, Layer 3 Bonding). We propose that dynamically switching a single flow among heterogeneous communication links is a simple and efficient scheduling strategy. Finally, architectures and protocols (MOBIKE, PMIPv6, LISP) are discussed regarding their eligibility for multipath communication and heterogeneous link bonding.
