A number of useful scripts have been entered in the UCS PowerTool/PowerShell contest. Here is what’s been happening since the 11th.
The scripts have started rolling in and I wanted to update you on what’s been posted to date. Maybe you could use them in your environment? To review these scripts and participate in the contest, head over to the Cisco Communities. Read More »
One of the great challenges of SDN – that many in my view underplay – is the change in paradigm from having a vendor deliver your network (hardware + software), to having (potentially) an ecosystem deliver your network – and this ecosystem may require you to develop software to perform network tasks or to integrate various SDN components together. This was recognized quite astutely by consultant Jim Metzler, which I discussed in one of my earlier blogs. “Applications can dynamically request services from the network” is what the SDN evangelists will tell you. Jim astutely asked “How exactly do they do that?”. Well ….. the true answer is that either (i) you need to buy [new] apps that do this off the shelf, as it were, or [more likely today] (ii) you need to modify your apps or develop new apps to do this.
So are you ready for procuring apps and/or developing software in your network design team now? Don’t worry if you say “no”. Let me first tell you a few customer reactions to this topic, and then let me update you on Cisco Services can help you develop new SDN apps that solve your specific network challenges.
Cisco has been playing a critical part for retail, healthcare, hospitality and transportation organizations to gain an understanding of how end-users move throughout an organization’s physical location. This is done through our Cisco Connected Mobile Experiences (CMX) solution.
With all the valuable information CMX provides, the demand for even more accurate data has been growing. Location accuracy has been a hot developing field and, as I mentioned in announcing our Best of Interop Finalist status in the wireless category last week, Cisco’s taken the lead in redefining how this location-based data is acquired.
In the past many solutions have relied on the probing performed by the mobile device to acquire location-based data. In recent months this approach has shown diminishing returns. The underlying issue is that this data is reliant on how frequently the mobile device probes an access point. A couple issues that arise include:
- Mobile device manufacturers are reducing the frequency of device probing to conserve battery. This reduces the number of data points collected and impacts the accuracy of the data
- Different manufacturers probe the access point with varying frequency so some devices deliver more accurate information than others skewing the location analytics data.
At Cisco’s annual Partner Summit event we are revealing some key areas of focus for the upcoming Cisco v8.0 release. Although the list is not inclusive of all new functionality, I would like to highlight some steps we are taking to bring CMX to meet the ever-evolving demand for location-based data.

Recently I had an opportunity to sit down with the talented data scientists from Cisco’s Threat Research, Analysis, and Communications (TRAC) team to discuss Big Data security challenges, tools and methodologies. The following is part one of five in this series where Jisheng Wang, John Conley, and Preetham Raghunanda share how TRAC is tackling Big Data.
Given the hype surrounding “Big Data,” what does that term actually mean?
John: First of all, because of overuse, the “Big Data” term has become almost meaningless. For us and for SIO (Security Intelligence and Operations) it means a combination of infrastructure, tools, and data sources all coming together to make it possible to have unified repositories of data that can address problems that we never thought we could solve before. It really means taking advantage of new technologies, tools, and new ways of thinking about problems.
