The only way to be sure of delivering highest quality of experience is by actually measuring QoE of real traffic. In IOS 15.1.3T, we introduced a new embedded monitoring capability to collect packet loss, jitter, delay and response time information for performance evaluation of data, voice and video services. The feature is called IOS Performance Monitor. (See yesterday’s blog on User Traffic Analysis by Medianet performance Monitor.)
In December of last year, Cisco IT was running a medianet pilot program for the new IOS performance monitor feature as their ongoing effort to provide high quality and improved services to end users. The pilot was designed to support 50 remote sites equipped with the ISR-891 routers. Two of the pilot sites were small Cisco offices and the remaining was home offices. I was lucky enough to be selected for the pilot.
Network operators are tasked with providing a foundation network that can deliver a variety of applications to their users at any time. For the most part, the network is in the background, humming away while users enjoy the applications. However; once in a while, the application will slow down, or hiccup, and the first suspect is usually the network.

Sometimes this is not without just cause; the network may be composed of various administrative domains in various states of work, and many things that are outside the domain of control of any network operator (bad fiber, rain clouds, bulldozers, floods etc.). There is the common experience of the ping test passing, but still something wrong within the network. Or the other case, where the ping fails intermittently, but there is no clue about the location of the problem.
Last week, Cisco Digital Media Systems (DMS) wrapped up another year at the world’s largest international trade show and conference dedicated to digital signage – the Digital Signage Expo 2011, held in Las Vegas. This year’s event came at an exciting time, just as Cisco was able to announce its 3000-customer milestone in digital signage and our market leadership in this bourgeoning industry after just four short years since joining the market in 2007.
For more insight from the show floor at DSE 2011, check out this video with DMS general manager Janice Litvinoff, outlining key highlights from the event and the unique digital signage applications on display this year at the Cisco booth.
In addition, we were thrilled to receive four Apex Awards, handed out by the Digital Signage Federation. Bringing in the gold award was …
Today, Cisco announced a series of new video offerings designed to make it easier for enterprises to create and consume video. Listen below as Cisco’s Director of Marketing for Enterprise Video, Erica Schroeder, outlines these new announcements and what it means for our customers.
Video applications such as telepresence, desktop video conferencing, video surveillance, digital signage and WebEx have become an essential part of the enterprise work environment, greatly improving efficiency and productivity in organizations.
Enterprise network IT operators are adding more and more of these applications on their IP network. Due to the nature of video traffic, these applications exert more demand on the existing IP network. If a network is not capable of handling these applications, then the application performance will degrade, resulting in a frustrating user experience. In this situation most of the network operators will tend to solve this problem by adding more bandwidth and capacity into the network, but that may not always solve this problem.
