The Cisco IT network services team views network programmability—the broader category that includes SDN, or Software-Defined Networking—as one of our top priorities.
To clarify terms, SDN is a network architecture that decouples the control plane (that is, the building of a routing table) from the data plane, moving the control plane to a software-based centralized controller. In Cisco IT, we see the real value of SDN as enabling network programmability. Network programmability requires two capabilities: harvesting information from network devices, and automatically pushing out new configurations in response to dynamic network conditions or service-provisioning requests.
We’re in the early stages of weaving network programmability into Cisco IT programs. So far, we’ve identified five internal use cases. Read More »
Cisco IT completely changed our voice and video infrastructure in the data center – and nobody noticed!
We changed the systems that Cisco IT uses to run ALL our voice and video supporting:
200,000 voice endpoints in 540 buildings around the world,
87,000 voicemail boxes
1600 TelePresence units
8.6 Million Webex meetings per year
Our customer contact centers handling 22M calls / year
It was a big job, migrating all these services off of 574 Cisco MCS servers, and onto new Virtual Machines running on 191 Cisco UCS servers in 12 different data centers. It took a while, but it was truly worth it, despite the fact that nobody noticed.
We reduced the amount of data center resources significantly – less space, less power, fewer cables. Even better, we now have all our voice and video running on virtual machines, making operations jobs and updates and growth a good deal easier, and faster. Best of all, though, we moved all our voice and video to a completely new server platform — and nobody noticed!
I spend a big part of my workday in virtual meetings, as an organizer, participant, or both. When I’m in my office, I can join those meetings from my desktop video endpoint, a Cisco TelePresence EX90, and enjoy the benefits of video communications.
But work isn’t necessarily a place that you go to anymore. I often work outside of my office, so the ability to easily join a video meeting from one of my mobile devices is critical for productive collaboration with colleagues. Read More »
According to a recent Cisco News article the Internet of Everything (IoE) is a multi-trillion dollar opportunity that incorporates data gathering, data processing, data analysis, data visualization, data optimization, data storage and retrieval, etc. Data is being generated at an exponential rate and with the IoE even more data will be generated.
The companies that win in this space are going to be the ones who understand how to synthesize meaningful relationships from the ocean of data (i.e. contextually relevant relationships), how to discern new knowledge, how to act on this knowledge, and how to communicate this new knowledge based on the context of an end-user or a machine.
Big Data technologies will play a pivotal role in the IoE, and therefore provide many opportunities for innovation; those wishing to gain a better understanding of several of the technologies involved in this exciting field are encouraged to watch the following video.
Despite all the buzz about software-defined networking (SDN), many organizations don’t yet have a clear idea of how it will benefit them. In this blog, I’ll tackle the what and why of SDN, and explain the different approaches you can consider.
What: A Disruptive Approach to Network Control
For the last quarter century, network devices have performed two types of processing:
The data plane looks at a routing table to decide where to forward packets. This processing takes place in dedicated hardware ASICs.
The control plane takes care of everything else, such as spanning tree, AAA, exporting NetFlow statistics, SNMP, and more. The control plane is implemented in software, and you can think of it as the brains of the network element.
So, if your network includes 200, 2000, or 20,000 network devices, that means you’re managing 200, 2000, or 20,000 control planes and keeping all of them up to date. Read More »
