IWAN Wed: The Case for Direct Internet Breakout at Branch and IWAN

Simplify Branch Security with ISRCloud services and SaaS applications is enabling customers to accelerate their business processes and improve employee productivity while lowering their total IT spending. The Cisco IWAN solution is helping organizations adopt cloud applications with an improved user experience by enabling local internet breakout from the branch environment, thus helping eliminate the need to backhaul internet-bound traffic across the WAN link. This helps provide the user improved experience through lower latency for not only internet applications, but also free up bandwidth for application on the WAN link. The reduced WAN link usage also means lower IT spending those links.

However, a study commissioned by Cisco during Jan’14 from 641 customers from US and Europe on their MPLS usage and adoption of local internet breakout found that 68% of the customers responded that enabling direct internet access was an organizational focus for them.  However, 54% of the total respondents reported that lack of sufficient security at the branch environment hindered them from enabling local internet breakout at the branch. This was ranked as the #1 reason to not enable Direct Internet Access at branch sites.

Demystifying the Catalyst: Video Application Monitoring and Troubleshooting

In my previous blog, we looked at how Catalyst switches can be used to assess video application readiness in the network before rolling out a video based collaboration application. In this blog, let us take a look at available tools on the Catalyst switches to monitor and troubleshoot video problems in the network.

As we know, fundamentally, video traffic is different from data traffic.  Video traffic is more dynamic and bandwidth intensive and even small changes in delay or loss can cause visible disruptions to user experience. Routinely, IT trouble tickets are opened by users that are faced with degraded video experience.  To add to that, interactive video is real time. Any delay in troubleshooting will make IT miss the window to rectify the problem. For a firm with many locations and buildings, finding the problem can be complex and time consuming without the right tools.
