Abstract
Clients can potentially have access to more than
one communication network nowadays due to the availability
of a wide variety of access technologies. On the other hand,
service replication has become a trivial approach in overlay
networks to provide a high availability of data and better QoS.
In this paper, we consider such a multi-homed client seeking
a replicated service in overlay network (e.g., CDN, peer-topeer).
Our aim is to improve the content distribution by
proposing a new model for being applied at the applicationlevel
and in a fully distributed way. Basically, our model
proposes to determine the best mirror server that could be
reached through each client’s network interface based on
application utility function. Then, it consists of downloading
the requested content from the determined best servers
simultaneously through their associated interfaces. Each best
server should deliver a specific estimated range of bytes (i.e.,
content chunk) to an independent TCP socket opened at the
client side for being finally aggregated at the applicationlevel.
Our real experiments show that our model is able to
considerably improve the QoS (e.g., content transfer time)
perceived by the client comparing to the traditional content
distribution techniques.
