Network managers today need to view, monitor and analyze their network traffic for a variety of reasons, including security, quality of service, compliance and deep packet inspection. Since all services are transported on a common converged network, isolating the service of interest can exhaust the resources of the monitoring equipment, adding significant capital and operating expenses. Here, Knowledge Center contributor Jesse Price discusses solutions for accessing traffic from converged networks, and presents an innovative approach to converged network monitoring access.
converged networks become a reality, network operators are facing
complex challenges with respect to network monitoring. Because
monitoring is a vital factor in the health of any network, tools that
monitor specific services traveling in the same converged pipe are
inundating the network. However, most of these tools only need access
to a small fraction of the data in a high-speed line. The process of
isolating the service of interest for each tool is exhausting the
resources of the monitoring equipment, which, in turn, is increasing
capital and operating expenses.
Network operators have to make a choice: either refit the network
with new monitoring equipment and distribute the traffic, or
eliminate the traffic that is not of interest. This article will drill
down into this problem, discuss solutions that have been implemented in
the past, and present a new, innovative approach to converged network
The network core is the optimal location to install network
monitoring equipment because all of the traffic throughout the network
will typically traverse the core. This approach to monitoring is not
without its problems though. Namely, because there are increasingly
faster data rates at the core, existing monitoring equipment can
quickly exhaust processing resources when sifting through the massive
amounts of data in an effort to find only the traffic that is relevant
to its specific monitoring requirements.
As network topology continues to grow, converge and increase in
speed, existing monitoring equipment often can be rendered obsolete
since it can no longer attach to the network. Compounding this problem
is the reality that networks generally have not just one, but multiple
best-of-class tools attached at the core-each of which needs access to
only a small fraction of the traffic that is traveling through the core
network on the same high-speed lines. As a result, none of the
tools operate at their peak performance levels.
