Data traffic has grown dramatically in the recent years, leading to increased deployment of network service appliances and servers in enterprise, data center, and cloud environments. To address the corresponding business needs, network switch and router architecture has evolved to support multi-terabit capacity. However, service appliance and server capacity remained limited to a few gigabits, far below switch capacity.
ITD (Intelligent Traffic Director) is a hardware based multi-Tbps Layer 4 load-balancing, traffic steering and clustering solution on Nexus 7xxx series of switches. It supports IP-stickiness, resiliency, NAT (EFT), VIP, health monitoring, sophisticated failure handling policies, N+M redundancy, IPv4, IPv6, VRF, weighted load-balancing, bi-directional flow-coherency, and IPSLA probes including DNS. There is no service module or external appliance needed. ITD provides order of magnitude CAPEX and OPEX savings for the customers. ITD is available on Nexus 7000/7700 series in NX-OS 6.2(8) or later. It is available for demo on Nexus 5k/6k. ITD is much superior than legacy solutions like PBR, WCCP, ECMP, port-channel, layer-4 load-balancer appliances.

Everybody’s talking about 802.11ac, but we’ve sensed some confusion for next steps as far as how CIO’s and IT organizations should be approaching the new standard.
Should I move to 802.11ac?
You’re probably thinking: Chris, you’re a leader at Cisco, of course you want me to migrate to 802.11ac. That, my friends, is where you are wrong. There is no simple answer to the question of whether you should move your network to 802.11ac. Here’s my simple rule of thumb:
There is no premium for 802.11ac from Cisco. If you are deploying new Access Points’s today, you should be buying 802.11ac. If you’re not buying, you are probably satisfied with your network and how it will handle the growth of more and more clients associating with your network and the bandwidth demands that come with that client demand. If you feel you have a plan to handle this demand, then you are one of the few that can pass on 802.11ac.
That said, there is a strong ramp up for Cisco 802.11ac products in the market, the AP3700 is the fastest ramping access point in our history and we have yet to see if the AP2700 will claim that crown in the coming months. ABI Research estimates that currently 50% of new device introductions are 802.11ac enabled, a statistic expected to increase to 75% by the end of 2015. This is enough proof of the overwhelming interest in adding the benefits of 11ac to networks. Let’s take a step back and consider the basics of why people are moving to the new standard.
Today, everything is about getting what we want, when we want it. Instant gratification. It’s not just the millennials—we’ve all been conditioned to expect things within seconds. Could you imagine the days pre-Internet if you had the capability for on-demand movies? Read More »

Today the Internet of Things (IoT) is everywhere: you can easily see smart meters on houses, parking sensors in the ground, cameras attached to traffic posts, and people wearing intelligent wristband and glasses -- all of them connected to the Internet. And this is only the tip of the iceberg: while you are reading this blog post factories, trains and trucks around the world are also being connected to the Internet.
Many traditional industries have historically requested help from different types of engineers to improve their processes and gain efficiency. Now they are asking us, the Internet engineers, to contribute solving new industrial world challenges by connecting billions of new devices.
The more ambitious part of this journey is the integration between both worlds: Information Technology (IT) and Operation Technology (OT). For that a systems approach is required to scale the existing Internet infrastructure to accommodate IoT use cases, while making IT technology easy to adopt for OT operators. We are facing a historical opportunity to convergence massive scale systems in a way we have never seen before, and such an effort will unlock a multibillion-dollar business.
In order to be ready to capture this opportunity and scale in a sustainable manner, four requirements are necessary:

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.

Cisco has been placing a lot of emphasis on delivering solutions that provide insights and understanding on how customers, patients, visitors and communities interact with their physical environments. Mobility and leveraging mobile devices in the environment has revealed itself as a very powerful way to gather critical business intelligence. This business intelligence is highly impacted by the resolution of the location-data and the demand to improve resolution and accuracy is increasing quickly. Apparently, this has not been missed by UBM. This year Cisco is honored to be selected as a Best of Interop Finalist for the Wireless award category for our innovations in improving location data resolution calculations.
It’s an honor to be recognized for our innovation and technological advancements in wireless, and we wanted to share a bit more about our submission with you.
What are Location Data Resolution Calculations?
Many systems acquire location analytics by relying solely on the probing that occurs from a mobile device to an access point. Unfortunately, this approach is delivering diminishing returns. It puts location analytics at the mercy of the mobile device vendors. What I mean by this is that as mobile device manufacturers look to improve mobile devices in regards to OS, drivers and battery life they are reducing the frequency of the probing from the mobile device. In addition, different mobile device manufacturer use different probing intervals. The need to do this makes sense from the mobile device manufacturer perspective, but it has an impact on the accuracy of the data acquired when representing movement of end users in the physical environment. If a user is recognized when they walk in the environment and then is identified a minute later, there is a lot of movement that can occur in that time. But the analytics only sees two data points and draws a straight line. Not a very accurate representation.
Cisco is leveraging what we know best, the network, to supplement the device probing. Bringing in network data allows us to gather higher data resolution regarding mobile device movement, equating to a more accurate representations of end user movement in the environment.
