Global Internet Routing Table Reaches 512k Milestone

omar-santosWritten by Omar Santos, Incident Manager, Cisco Product Security Incident Response Team (PSIRT) Security Research and Operations

Since the early 1990s, we’ve watched as the number of entries on the Internet routing table has steadily grown. In 2008 the table reached 256,000 routes, triggering action by network administrators to ensure the continued growth of the Internet. Today we know that another significant milestone has been reached, as we officially passed the 512,000 or 512k route mark!

Our industry has known this milestone was approaching for some time. In fact it was as recently as May 2014 that we provided our customers with a reminder of the milestone, the implications for some Cisco products, and advice on appropriate workarounds.

If you would like to revisit that information, you can find the customer support article here: The Size of the Internet Global Routing Table and Its Potential Side Effects (12 May 2014)

Cisco’s 802.11ac Portfolio Expands with the New Cisco Aironet 2700 AP

As a Product Manager there is some anxiety but more of an excitement around introducing a platform to the market. Today I am proud to be part of Cisco team that is  bringing to market the Cisco Aironet 2700 Series Access Point.  What it offers is a tremendous amount of power at a very attractive price point.

We all know Wi-Fi is here to stay and is expanding all around us rapidly. That need for speed is exciting.  But what does that mean? Not everyone feels comfortable being on the cutting edge. Many of our customers are not as concerned about chasing the future and have more limited budgets that they hesitate to put down for the best AP knowing there are lower priced options.  At the same time, everyone is aware technology moves ahead with or without you, so they don’t want to give up lot of the new capabilities by going totally to the other extreme of not upgrading at all.  What they want is something that’s going to last for a while that gives them the advantages available today, but not have to invest a lot to get it. I equate this to buying something like a car.  A year ago when I was in the market to buy a new car I didn’t want to sacrifice whole lot of options but if there was one or two options that I could give up in order to save a bit of money, I was okay with that.

This is similar to what Cisco is offering with Aironet 2700 Series.  Customers have to choose something that they can utilize in their network that is better than any of the competitive solutions out there, truly built-for-purpose, sleek design on the outside yet tough on the inside and very powerful.

Not All 802.11ac AP’s are Created Equal: Built-for-Purpose vs. Purpose-Built

As more and more 802.11ac devices come to the market this year, businesses need to make sure the best possible 802.11ac wireless infrastructure gets deployed to make sure those 802.11ac end points are performing at both the best possible data rates and application throughputs to maximize the move to  802.11ac.

Cisco’s Aironet 3700 with HDX Technology does just that. If you’re thinking that the 3700 is just another 802.11ac AP,  think again: not all 802.11ac AP’s are created equal.

To demonstrate this, let’s take a Cisco 3700 access point..

When you open a Cisco AP, you will see dedicated memory (RAM) on the radio chipset itself (one on the 2.4 GHz radio, another on the 5 Ghz radio) to ensure the RF packets get processed “onboard” each radio instead of “offboard” in order to reduce latency and any packet processing collision from memory contention on the AP. Additional packet processing can be handled  on the “offboard” memory that is part of the network processor portion of the AP platform as well. This unique, innovative ASIC-based Wi-Fi chipset by Cisco exemplifies the built-for-Purpose design, and is the hallmark of Cisco’s 3700 Series AP.

Contrast this with the competitive landscape that claims to be Purpose-Built, but in reality is leveraging off-the-shelf merchant silicon-based 802.11ac WiFi chipsets. Read More »
