Abstract
Many modern devices come with several, heterogeneous,
network interface cards (NICs). However, simple
operations like transferring data flows to the cheapest NIC or to
one with enough Quality of Service (QoS) are awkward tasks on
most Operating Systems. In this paper, we discuss the criteria
to select the proper NIC for a given data flow. We also present
a new Operating System service, called netqos, to publish data
and figures of merit for these criteria. The main objective of
netqos is providing relevant information to applications and
middleware about NIC selection criteria, isolating them from
the idiosyncrasies of the many QoS gathering tools and allowing
to choose the proper NIC to fit their needs. We have built this
new service as a synthetic file system for the Linux kernel. We
describe our experiences in using it in a real-world scenario
and the practical and inherent limitations of this approach
