Miercom: Cisco Aironet AP3702i

Cisco’s newest 802.11ac product, the Aironet 3700 Series Access Point is now orderable and shipping in the next few weeks.  The AP 3700 features an integrated 11ac radio with a 4x4 architecture and Cisco’s High-Density Experience (HDX) Technology.  HDX is a suite of features specific to the AP 3700 that delivers the best possible user experience, especially in high client density networks.  HDX is enabled by a combination of  hardware and software features on the AP 3700, features including:

  • CleanAir 80 MHz – Interference detection and mitigation
  • ClientLink 3.0 – RF link quality
  • Smart Roam – Intelligent roaming handoff
  • Turbo Performance – Performance with high client density

Aruba recently launched their 802.11ac access point, the AP-220 series, featuring a 3x3 design.

Miercom recently published a third-party evaluation of the performance between the AP 3702i and the AP-225.  The report consists of a diverse range of test cases meant to gauge real-world performance of the access points.  The tests include; multi-client performance, single client rate vs. range, performance in the presence of interference, and performance on reduced power.  Here are some of the highlights from the report.

Multi-Client Performance

The AP 3700 performed very well in the multi-client performance test, thanks impart to HDX Turbo Performance.  With 60 clients, the AP 3702i had a 6x performance advantage over the AP-225.  The AP-225 struggled to serve all the clients and only mustered 40 Mbps total.  The AP 3702i was able to transmit a healthy 236 Mbps, while maintaining fair throughput to each client.

The test consisted of 60 11ac clients, all associated to the 5 GHz radio.  The clients used were 10 Dell E6430 laptops with Broadcom 4360 three spatial-stream chips, 20 Apple Macbook Air two spatial-stream laptops, and 30 Dell E6430 laptops with Intel 7260 two spatial-stream chips.  Clients were setup in an open office environment surrounding the AP.  Distances varied from 10’ to 50’.

The Future of Work: A Trans-Tasman Telework Survey

Contributed by: Tim Bentley, Director of the NZ Work Research Institute at AUT University

Teleworking (also referred to as telecommuting or flexible working) is known to have many benefits to both employee and employer alike. However, recently AUT University’s NZ Work Research Institute, in collaboration with the University of Melbourne’s Institute for a Broadband-Enabled Society, delivered the findings of research examining manager and employee perspectives on telework productivity and wellbeing in Australia and New Zealand. The research was commissioned by industry partner, Cisco.

This study has found strong evidence of the positive benefits of telework for both individual workers and their organisations. The key study finding is that telework promotes improved productivity and satisfaction with work, with hybrid teleworkers performing better than those who do little telework. These conclusions are supported by findings from both the on-line survey which measured productivity, where teleworkers out-performed non-teleworkers, and from manager interviews, with managers expressing high levels of satisfaction with their teleworkers’ productivity.

Virtualization: Can We Deconstruct the Problem and Opportunity?

This was the title of a November 19 2013 panel that I had moderated in Washington D.C. at the MPLS-SDN Isocore Conference.

The abstract for this conference was designed to be a bit provocative, specifically:

“ Virtualization as a concept is not new. However, in the context of Software Defined Networking,the virtualization discussion has been focusing on overlay functions e.g networking. What about virtualization overlays and interworking with existing architectures?   What are the implications to performance and management?   Are we speaking the same language?

The panelists will have an opportunity to articulate the virtualization problem space for the industry and the opportunity for the industry to address.”

My panelists included the following individuals: Read More »

Securing Critical Internet Infrastructure: an RPKI case study in Ecuador

Securing the Critical Internet Infrastructure is an ongoing challenge for operators that require collaboration across administrative boundaries. Last September something exceptional happened in Ecuador, a small South American country. The entire local network operation community got together to be pioneers in securing its local Internet infrastructure by registering its networks in the Resource Public Key Infrastructure (RPKI) system and implementing secure origin AS validation. This project is a great example on how a global technology change can be accelerated by maximizing its value to local communities.

The global inter-domain routing infrastructure depends on the BGP protocol that was initially developed in the early 90s. Operators know that a number of techniques are needed to improve BGP security (a good reference can be found here). Although these improvements, it is still possible to impersonate the entity with the right of use of Internet resources and produce a prefix hijack as the famous attack in 2007. The IETF, vendors and Regional Internet Registries have been working inside the SIDR working group to create technologies that allow the cryptographic validation. The initial outcomes of this effort have been the RPKI and the BGP origin AS validation; two complementary technologies that work together to improve inter-domain routing security.

The Quickest Way To Get Started with ACI

November 19, 2013 at 10:26 am PST

By now, given all the launch and blogging activity activity over the past week or so, I am sure your understanding of and interest in Application Centric Infrastructure (ACI) will have grown.   Many of you will be asking “how do I get started as quickly as possible?”, and “how can I free up some time and resources to investigate?”  You understand the “what” - now, as I blogged recently on SDN, it’s time to understand more about the “why” and take action on the “how”.   How then do you get off that start line as quickly as possible?

Get Set To Go With ACI

Get Set To Go With ACI

As with many things in life, it helps if you get help from someone who has “been there” and “done that”.  And that’s where Cisco Services comes in, as Scott Clark, the VP for our Data Center Services team, introduced  last week.  So let’s talk about why Cisco Services should be your partner in this application centric world, and what services can help you.
