802.11ac: Is Your Network Infrastructure Ready for Next-Gen Wi-Fi Traffic?

The next generation of Wi-Fi, 802.11ac couples the freedom of wireless with the speed of gigabit Ethernet. This also translates in additional load on the backbone of the network, which has to deliver at least 3 times the capacity of the current gold standard, the 802.11n based network.

Cisco launched the Unified Access architecture  to scale linearly with the increased load on the network with 60 Gbps Wi-Fi throughput on the Cisco 5760 Wireless LAN Controller and 40 Gbps Wi-Fi throughput on the Catalyst 3850 Series Switch with a built-in wireless controller.  Both these platforms are based on the Cisco Unified Access Data Plane (UADP) programmable ASIC, which provides high performance and scale, common open APIs, and enables consistent QoS policies for both wired and wireless networks.

Aruba recently launched the 7240 series controllers with a throughput of up to 40Gbps claimed, with the same goal of delivering 802.11ac capable performance across the network. This controller is based on a generic network processor and not a purpose built ASIC like the Cisco controller.

Miercom performed a third-party evaluation to benchmark these products  using  IMIX (Internet Mix) packet traffic and test QoS traffic for high priority application.  IMIX is traffic pattern consisting of a preset mixture of small, medium and large frame sizes used to emulate real-world traffic scenarios in a testing environment. We wanted to give you a sneak peek at some of the results.


Cisco 5760 is six times faster and Catalyst 3850 is 4 times faster as compared to Aruba 7240


The Cisco 5760, 3850 and the Aruba 7240 were tested for throughput using RFC 2544 and IMIX Traffic.  The Cisco 5760 and 3850 performed extremely well by achieving 50 Gbps and 37 Gbps, whereas Aruba 7240 fell short by just achieving 8 Gbps, which is 20% of its advertised throughput.

Momentum is growing for the Cisco ISR-AX!

It has been a couple of weeks since its launch and we are seeing lots of interest in the Cisco ISR-AX!  I have been hearing from customers, partners and folks  worldwide about how they are using the new ISR-AX platforms now and get a router, VPN, firewall, intrusion prevention, cloud/web security, AVC (NBAR2, QoS, NetFlow, Media Monitoring, PfR) and WAN optimization (WAAS) all in one box for less than the cost of just an alternative WAN Optimization appliance.  For WAN optimization with WAAS that is less than $1 per WAN optimized connection with ISR-AX!

Anyway, I’ve gotten lots of questions since the launch, so I grouped them and wanted to share the top 4: Read More »

What Cisco Partners Need to Know About the New Release of VXI

Cisco partners have told us multiple times that the Virtualization Experience Infrastructure (VXI) continues to be the Gold standard for Virtual Desktop Infrastructure (VDI). We appreciate your input. At the same time, we know there’s more we can do to help you.

So we’re happy to share with you that a new release of VXI comes out today. What does this mean for you?

Let’s have a look first at what’s new, how this meets your customers’ demands, and then how that applies to your business.

First, key to the announcement is an opportunity for partners to now offer Cisco’s collaborative services, enabled by Cisco Jabber. This means customers can select the work style most suited to their needs: mobile, fixed, and now virtual. Cisco Jabber for virtual environments is enabled by Cisco Virtualization Experience Media Engine (VXME), a new software component that delivers high-definition video and voice communications to be integrated as part of a virtual desktop session.

Why is this important for your customers? Read More »

Demystifying the Catalyst: IOS Device Sensors

In this blog, let us take a look at how Catalyst access switches profile the various connected devices and make the information available to various network services.

Many devices like laptops, IP phones, cameras etc. are connected to the network and need to be managed by IT for asset management, device onboarding, switch configuration, policy management & device energy management. Traditionally, IT administrators manually added each device for each service. This consumes unnecessary overhead and is an inefficient use of IT’s time. Read More »

Five Cool Router Tricks with onePK

Network Management is dull.  No excuses.  Monitoring and interacting with the devices that move data from one location to another is a thankless undertaking that most of us building networks leave to an afterthought.  Part of that is the complexity associated with managing networks.  There are at least a dozen common methods for interacting with devices in the network including SNMP, CLI, AAA, Syslog, Netflow, and fancy XML/HTTP interfaces.  So much variety breeds complexity so we tend to set our goals pretty low for interactivity with the network.

What if we had one common mechanism for interacting with the network?  Different devices running different software would all speak a common language to the applications managing and monitoring them.  Now what if that language was something the programmers writing those applications understood implicitly like an API library they could compile directly into their program?  That would make interacting with the network as simple as making a procedure call within the application.  That’s exactly what onePK – or the “one Platform Kit” – accomplishes.
