Multihoming is increasingly being employed by large en­
terprises and data centers as a mechanism to extract good
performance from their provider connections. Today, mul­
tihomed end­networks can employ a variety of commercial
route control products to optimize performance over multi­
ple ISP links. However, little is known about the mechanisms
employed by such products and their relative trade­offs.
In this paper, we propose and evaluate a wide range prac­
tical schemes that could go into the design of a route con­
trol device and analyze their trade­offs. We implement the
proposed schemes on a Linux­based Web proxy and per­
form a trace­based emulation of their relative performance
benefits. We show that both passive and active monitor­
