On the Feasibility of Switching ISPs in Residential Multihoming
Overview In theory, multihomed Internet hosts, that is, hosts simultaneously connected to multiple Internet Service Providers (ISP) should see increased access capacity, be able to circumvent possible last-mile congestion problems, and experience improved end-to-end Quality of Service (QoS). In practice however, the advantages one can gain from multihoming are highly dependent on the path switching mechanism used, that is, on dynamically deciding which ISP should be used as a first-hop. This paper is a first step toward understanding the trade-off between performance improvements multihoming can help achieve and the complexity of the decisions that must be made. We measure changes in end-to-end network layer metrics (loss, latency, jitter) over the different paths available from a multihomed host to a large population of Internet hosts.
