easily configurable webcache appliances. They offer the following
benefits to your network:
Reduced Network Traffic
I
The Webcache locally stores frequently accessed Web content and
quickly serves it to the end user on demand. This reduces the amount
of traffic on the WAN, providing significant cost benefits by reducing
the bandwidth requirement on expensive WAN links.
Reduced Web Latency
I
The end user receives Web content more quickly and with greater
quality of service if it is served from a local, high-speed Webcache
than if it is served from the Internet. Web object requests that have to
travel over long distances are limited to the speed and capacity of the
slowest link in the path. A Webcache that is closer to the client
machines reduces the potential for slow links and dropped data
packets.
Smoother Traffic Flow
I
Traffic surges can stress your network and server. The Webcache can
help smooth out network traffic and reduce delays in serving Web
content. As more users request the same Web content, it becomes
more likely that the content will be stored in the Webcache, and in
turn the Webcache becomes more effective at eliminating upstream
traffic.
Controlled Web Access
I
The Webcache allows you to control which client machines in your
network can access the Internet, and which Web sites can be
accessed. Access Logs show you who has used the Internet and where
they have been.
The latest version of 3Com Network Supervisor is supplied on the
CD-ROM that accompanies the Webcache. 3Com Network Supervisor
provides powerful, intuitive network management for small to medium
enterprise networks. It automatically discovers network devices and
reports network activity, stress monitoring and performance metrics for
network managers. This information helps to provide the most efficient,
cost-effective use of network resources.
