So far, so good at Cisco Networkers in Barcelona this week. Despite spirits being a little tempered by the worldwide financial crisis, attendance seems to be quite good and we are noticing a radical shift in what enterprises and service providers are trying to accomplish with their networks.
One topic that’s a bit been very popular with this audience is the concern about VoIP and video quality on converged networks. So you could say network pros are more jittery here about latency-sensitive UPD applications than they are about the macroeconomic situation.
Moving on…
The primary concern about video has shifted from quashing recreational YouTube viewers to ensuring the network can carry video. We spoke with several different companies (with headquarters from Sweden to Qatar) that have requirements to stream video across the WAN as part of their mission. I was involved in several conversations and overheard several more where the main topic was using application-aware network management tools and techniques like IP SLA and how to determine, validate and assure QoS.
I have to say I was pleasantly surprised about the awareness of the Cisco NAM support we announced the day before yesterday. It seems like before the news even hit the wire we had several attendees asking how they could use their NAMs alongside NetQoS. There are some monster implementations of NAM out there so everybody’s happy when you can leverage the existing investment for better application response time monitoring and performance troubleshooting.
