Research output: Chapter in Book/Report/Conference proceedingConference contribution


We present a novel system termed Binder that seamlessly
aggregates multiple geographically distributed Internet gateways
in community networks. The proxy based approach
taken in Binder allows for applications on end-user devices
to enjoy the benefits from gateway aggregation without requiring
any modifications. Binder makes novel use of multipath
TCP (MPTCP), and additionally leverages OpenVPN
tunneling and loose source routing (in a limited form that
avoids security concerns) as part of an easily deployable implementation.
Binder supports flexible gateway aggregation
without negative e↵ects from packet reordering through its
use of MPTCP and generalizes link aggregation mechanisms
to handle distributed links. Our proof of concept evaluation
of Binder using a real implementation over an emulation
based lab testbed demonstrate its benefits in terms of bandwidth
aggregation, load balancing and fault tolerance relative
to common practice.
