This week, I invited Chris Cullan, product marketing manager, business
services solutions at InfoVista to discuss his “grumpy old man syndrome (GOMS).”
Not really a grumpy old man, Canadian
Chris will share how Cisco and InfoVista are working together to solve GOMS by giving communications service providers (CSPs) and their enterprise customers the ability to bridge the application – user – business gap. Specifically, Cisco and InfoVista can help CSPs and customers detect and apply QoS to over 1400 applications, including bit-torrent, p2p apps, Netflix, Youtube and about 1400 others – without probes and at a hardware cost up to 30% lower than standalone appliances. Cisco also produces monthly updates to application signatures that can be implemented without interruption to the network.
Please join our free upcoming joint webinar on Thursday, June 13th at 8:00 a.m. Pacific Time; it will be moderated by Light Reading, a leading trade publication.
Take it away, Chris!
Thanks, Bob. I’m not really that grumpy. I’m Canadian, after all.
One thing really annoys me…okay, many things really annoy me, and the number seems to increase as I get older. I call it “grumpy old man syndrome”. My wife just calls it painful. But for this audience, the one thing I am referring to is “dumb pipes”. I am continually frustrated by the industry’s willingness to down-play its core value.

Coming off a busy week at Interop Las Vegas, we have recorded another info-packed podcast with the popular wireless networking podcast group “No Strings Attached Show”. The topic for this podcast covers the gigabit wireless technology, 802.11ac which if you attended Interop, you know this is a very hot topic (“I’ll take enormous understatements for $600, Alex”).
However, it is not just a discussion on what is included in the standard. Blake Krone and Sam Clements from No Strings Attached interview our Mark Denny and Brian Hart as they discuss a number of topics related to 802.11ac technology including the following:
– The 802.11ac Wave 1 Radio Module for the 3600 Access Point, the availability and best practices for upgrading the 3600 AP with the 802.11ac Module
– Segments of the enterprise market where 802.11ac technology is generating the most interest Read More »

If you recall, back in the early days of 802.11n, the Wi-Fi Alliance (WFA) rolled out the 802.11n certification program in phases. Here we are several years later and in that same fashion, the WFA has split the IEEE 802.11ac specification into two certification phases: Wave 1 and Wave 2.
Last week we announced the availability of our 802.11ac Wave 1 Module for the 3600 Access Point and along with that, our intention to develop an 802.11ac adaptive radio module that will support the second phase of 802.11ac, or Wave 2. Most of the 802.11ac discussion in the last year has been focused on Wave 1, so we want to kick off the conversation about the second phase, Wave 2.
If Wave 1 promises increased wireless performance to address the increasing demand for higher performance including growing number of clients demanding higher performance for applications such as HD video streaming, then Wave 2 will stun you with its ability to provide even more throughput beyond the 1.3Gbps that Wave 1 provides as well as a number of other features that will further improve wireless connectivity. It is like taking a really good rock song and adding more cowbell to it.
SNL jokes aside, with the additional features packaged in Wave 2 comes the opportunity for further innovation in Cisco’s Wireless portfolio. We feel that it is important to stay ahead of the technology curve so that customers can plan and benefit from these advances sooner rather than later. So let’s discuss what features are coming with 802.11ac Wave 2. Read More »

What’s new and exciting with EIGRP (Enhanced Interior Gateway Routing Protocol)? Actually, lots… First a bit a background on EIGRP.
EIGRP is an advanced distance vector routing protocol used extensively by enterprise customers. It is very popular because it is simple to deploy and support. Some major attributes are:
- EIGRP does not mandate many network design requirements and is therefore perceived as “forgiving” and “flexible”. For example, EIGRP does not require support for multiple routing sub-domains or Areas.
- While route summarization is a recommended best practice to minimize route table size, it is optional with EIGRP.
- EIGRP can scale to support thousands of routers in a Hub and Spoke configuration. The Hub and Spoke design is especially popular in WAN networks.
For additional information on EIGRP, please click here. There is also a great BLOG that compares EIGRP and OSPF that I think you will find informative and is posted here.
While EIGRP has a large customer following, some customers have hesitated because of concerns of EIGRP being “proprietary”, which would prevent them from multi-vendor network support. In some cases this has caused customers to design their networks to limit usage of EIGRP, even though they would like to deploy it ubiquitously. One result has been non-optimal network design and traffic flow, resulting from multiple IGP (Interior Gateway Protocol) redistribution points.
That brings me back to what is new and exciting with EIGRP. Read More »

In light of the recent announcement of MSE Release 7.4 and Advanced Location Analytics Availability, we thought it would be timely to pick up where we left off on our MSE blogs series. In the first two, my colleague Anshul Tyagi covered how the MSE optimizes the CleanAir experience and discussed other MSE enhancements. Now that we have expanded the MSE to cover advanced location analytics, let’s use this blog to dive deeper into how to monetize your Wi-Fi infrastructure using our new functionality.
So you have a Cisco Wi-Fi network: what can you do to get more insight into the people using it? Do you know which part of your venue is more crowded? Ever wondered where people spend the most of the time in your venue? Where have people been before they arrived at your venue?
Whether it is in retail, leisure, travel or manufacturing, anytime there are people interacting with a Wi-Fi environment, there is also potential to improve the user experience–that is, if you can first visualize that interaction.
With the acquisition of ThinkSmart technologies, a leading data analytics company proficient in location data mining, Cisco opens up a new customer base – that of customer oriented marketing. Cisco ThinkSmart Location Analytics solution leverages your existing WLAN infrastructure and can help you gain insight on customer behavior, giving you an opportunity for better sales and operations.
How does the Cisco+ThinkSmart Analytics work?
