ABSTRACT
Content delivery networks (CDNs) have been widely used to pro-
vide reduced delay and packet loss, fault tolerance, and improved
scalability for web content delivery. Additional benefits are pro-
vided for video streaming when one designs a Streaming Media
CDN (SM-CDN) for either conventional single description (SD) or
multiple description (MD) coding. Specifically, when precise net-
work conditions and topology are known, simulations show that an
MD-SM-CDN can provide 20 to 40% reduction in distortion over
a conventional SD-SM-CDN, even when the underlying CDN is
not designed with MD streaming in mind [1].
This paper examines the performance of an MD-SM-CDN as
a function of different network topologies and loss conditions, and
compares it with a conventional SD-SM-CDN. This examination
