In a prior blog post, I talked about latency analogies. I compared levels of latencies to your home, your neighborhood, a far-away neighborhood, and another city. I talked about these localities in terms of communication.
Let’s extend that analogy to talk about data locality.

The announcement today of OpenDaylight is big news. Industry leading companies are partnering via Open Source to serve an emerging set of market needs:
- Operators: want affordable real-time orchestration and operation of integrated virtual compute, application, and network.
- Application Developers: want a single simple interface to the network. Underlying details such as “router”, or “switch”, or “topology” can be a distraction they desire to abstract and simplify away.
- Equipment Vendors: want a stable forum to interwork a plethora of Application interfaces with a plethora of nascent Network Device programmatic interfaces.

Cisco Live Orlando, June 23-27, 2013, is quickly approaching and registration is open. The Security track this year includes 72 breakout sessions, 74 hours of labs and seminars, and 3 Product Solution Overview sessions, accounting for about 15 percent of all the content delivered at Cisco Live. New for this year we will have several talks aimed at the network engineer in the role of a data analyst, helping them to better utilize and understand the data that comes from their networks (BRKSEC-2001, BRKSEC-2006, BRKSEC-2011, BRKSEC-2062, BRKSEC-3031, and BRKSEC-3062).

Hey everyone, the latest component of Cisco Unified Access was announced at Cisco Live Londonat the tail-end of January. The architecture brings policy, management and network together to tackle mobility, BYOD and collaboration needs in the enterprise for today and tomorrow. I want to give you all a quick summary of how I play a pivotal role in this architecture. I’ve also got a new whitepaper to share. Read More »
Today, April 8, 2013, the brightest of Wall Street are meeting at the 10th Annual High Performance Computing Linux for Wall Street event in New York to learn about the latest technology innovations that give financial trading firms a competitive edge. With network latency achieving speeds of less than 50 nanoseconds, this year’s event focuses not only on speed but also on cutting-edge advances in network visibility, analytics and instrumentation. One way Cisco is helping traders gain a competitive edge in this area is by offloading the gathering of analytics data to the network devices, and working with industry leading monitoring firms like Corvil and TS-Associates to decode these new sources of data.
No doubt, high performance trading systems are becoming faster, processing more data than ever before. Network performance is of paramount importance in high performance trading markets where obtaining and acting on real-time equities, options and other financial market information, nanoseconds faster than competitors, may be worth millions of dollars. While complex trading analysis and risk mitigation still need to be performed outside the network layer, significant cost savings and scale advantages can be obtained by leveraging embedded intelligence in the network to enable key functions such as fabric congestion monitoring and intelligent traffic mirroring.
