in on the new opportunity

Opportunity
is brewing quickly in the fledgling world of content delivery networks
(CDN).
Experts
believe that in about three years, business customers will invest
heavily in content delivery services, which will handle video, interactive
and other content that cannot yet run with current Web configurations.
The CDN services market is projected to grow from $97 million last
year to $2.2 billion in 2003, according to the HTRC Group. CDN product
sales will climb from $122 million in 2000 to $1.3 billion in 2004.
The
most likely users of CDNs will be corporate intranets, as well as
public Internet sites. For instance, IBM and Merrill Lynch have
installed CDN intranets.
Essentially,
a CDN is an overlay network that runs on top of the Internet to
hasten rich content downloads. Beyond the "static" content
currently administered by ISPs and ASPs, most CDNs handle only streaming
audio and video.
Some
CDNs operated by market leaders Akamai and Digital Island leverage
ISPs' existing data centers and pipes, while new breeds of CDNs
such as Orblynx opt for a satellite-based approach.
In
addition, some CDNs are shifting to "dynamic" content,
such as Web pages generated during personalization. Still ahead
is "interactive" content, involving bidirectional real-time
communication.
While
most CDN vendors sell direct, some, like SpiderCache, plan to add
reseller programs in North America. Also, Network Appliances, another
player in distributed caching, has teamed with IBM Global Services.
Meanwhile,
smaller, specialized integrators like Pulse Digital, an integrator
specializing in video, has produced a solution that integrates streaming
media technology by Anystream. And Minerva Networks, a maker of
video gateways, has worked with smaller integrators in Video over
IP technology for CDN telco trials in Florida.
"Voice
and data are quickly becoming commodities. There are lots of possibilities
in video for both integrators and ISPs," says Mauro Bonomi,
president and CEO of Minerva. "An integrator can customize
the way consumers navigate through the (video) environment. An ISP
can either simply manage the network, or provide the content, as
well," Bonomi says.
While
infrastructure players like overseas telco Hong Kong Telecom are
adding CDN services, some see ISPs creating partnerships. "I
don't envision ISPs in their present configurations as migrating
over to become CDNs. Instead, ISPs and ASPs will partner with CDNs,"
says David Yerushalmi, director of business development for eMikolo
Networks, maker of an appliance that integrates caching with CDN
technologies.
