Visual Networks monitors DSL, VPN links
Visual Networks' monitoring software will soon make it easier for
service providers and enterprises to troubleshoot problems with DSL and
Visual's Visual IP InSight software this summer will include
software that distinguishes IP problems on a connection from problems
with the physical link itself, the company announced at
The software consists of an agent that runs on an end user's Windows
PC and on a server in the provider's network where customer data is
gathered and stored. Network managers can access summaries of traffic
in and out of a customer's machine.
The company says enterprises might use the VPN monitoring to sort
out problems remote users encounter when they connect to corporate
headquarters through VPN tunnels. For example, a customer connected via
a DSL link to a VPN might have trouble connecting. Using Visual IP
InSight 5.5, the provider can see whether the problem is caused by the
DSL link to the Internet or with the VPN tunnel being created across
Earlier releases of the software could perform similar analysis on
The same data collected in reports can verify whether service
providers meet service-level agreements on DSL and VPN services.
The DSL software, called Broadband Advisor, determines whether a
connection is PPP over Ethernet or PPP over ATM, how fast the
connection is, the number of call failures, the time to connect to the
network, and information about the hardware and software configuration
of a user's PC.
The VPN package, called IP-VPN, determines whether connections are
PPTP or IP Security and determines how well the VPN tunnels are
Available in August, IP InSight with the Broadband Suite and IP-VPN
costs $193,000 for a service provider with 10,000 users.
