Earlier this year, we wrote a newsletter about route analytics. In that, we defined the goal of route analytics as being to provide visibility, analysis and diagnosis
of the issues that occur at the routing layer. Route analytics has typically been regarded as a niche technology. However,
we have recently been talking to both end users and vendors and those conversations have convinced us that route analytics
is poised to cross the chasm and become a mainstream technology for IT organizations that have complex meshed networks that
support business critical applications.
To demonstrate its potential, today, we’ll summarize some of the conversations we’ve had with a number of IT professionals
on the value of route analytics. The next newsletter will summarize conversations with route analytics suppliers. More information
on this topic can be found here.
One of the IT professionals who we talked with about route analytics works for a large government organization. He is a team
leader for network engineering and will be referred to in this newsletter as The Team Leader. As a result of deploying applications
such as VoIP, The Team Leader has a number of projects in place the goal of which is to increase the resiliency of the network.
A key component of the organization’s overall resiliency strategy is to rely on OSPF (Open Shortest Path First) to identify
alternative paths through the network. However, as The Team Leader stated: “A single misconfiguration on a backbone router
causes havoc.” He pointed out that before the organization implemented route analytics it typically didn’t know that there
was a routing problem until a user complained. Once it determined that there was a problem, the traditional approach to troubleshooting
OSPF required analysis of each individual component of the network and that route analytics allow the organization to identify
and resolve problems before they impact users.
We also talked to a network engineer for a large utility who will be referred to in this newsletter as The Network Engineer.
Like The Team Leader, The Network Engineer stated that increasing the availability of the network was a key goal of his organization.
Before deploying route analytics, his organization responded to a routing problem by “digging really deep and going device
to device”. The Network Engineer stated that the value of route analytics is that it reduces the amount of time it takes to
resolve a problem with the routing infrastructure.
