Enterprise Networks and the Drive for IPv6

It was not that long ago that whenever I read an article about IPv6, it usually discussed how the IPv4 Address depletion in other countries. At that time, the adoption of IPv6 was coming from other countries that where the v4 address space was depleted, the US Government, or Service Provider. Well fast forward only a few years and you can include Enterprise Networks in that mix.

Driving this IPv6 train for enterprise networks is wireless technology and the enabling by-product, BYOD. Wireless technology, in particular, Wi-Fi has grown from a toy to a requirement in most businesses today. We have moved from 802.11b which gave you a max datarate of a paltry 11Mbps to 802.11n to a max datarate of 450Mbps if you currently deploy the Aironet 3600 Access Point that supports 4×4 MIMO; if not, it’s a max datarate of 300Mbps. Never mind the fact that we will soon see the Wave 1 version of 802.11ac will have a datarate of 1.3Gbps and Oh BTW, Wave 2 promises a scorching datarate of 6.9Gbps!

Mobile World Congress 2013: Coping with Exploding Data Demand

A dominant theme for the mobile networking industry at this year’s Mobile World Congress was how to cope with exploding demand for mobile data. Part of the answer is new technology but part is better spectrum policy.

Network operators today are facing a stiff challenge to expand infrastructure to keep pace with data traffic growth as more consumers stream HD video on their mobile devices and businesses employ collaboration tools to increase productivity.  As a result, service providers are working harder than ever to manage their networks and scarce spectrum by deploying high quality small cell Wi-Fi in combination with traditional macro cell base stations. This is the “heterogenous network” or Het Net.

Just a few years ago, Read More »

Move Over SDN – NFV Taking the Spotlight

Energetic debates of what SDN is and the expanding scope of what it can do for our customers continue to race along in a chaotic frenzy. In addition, the overall SDN market is somewhat fragmented in terms of both vendor positioning and marketing.  Collectively, the conversation really comes down to improving business agility and the efficiencies gained in bringing new services to market. Essentially, the goal is to enable operators to make their networks and services go much faster.

While software defined networking (SDN) technologies continue to drive significant entropy in our industry, Network Function Virtualization (NFV) recently rose up and became a key focus of many discussions at Mobile World Congress in Barcelona last month. Read More »

Client Adoption for 802.11ac Wireless Technology

When it comes to the adoption of new technology such as 802.11ac, the industry becomes a farmer’s almanac of predictions when it comes to when and what devices and products will announce 802.11ac support.  Aside from Cisco, who boldly announced support for 802.11ac on the 3600 Access Point for the enterprise, there have been a number of consumer devices such as home routers, bridges, a selection of USB clients and a single gaming oriented laptop that are offering support for the new 802.11ac specification.

With HTC’s announcement of 802.11ac support for their HTC One smartphone, we would expect others to follow suit in the near future, setting the stage for the first series of devices to bring integrated 802.11ac to market sometime in CY13. As these device become available you can expect them to be connecting to your corporate networks as BYOD devices for corporate use. With the devices come the expectations where your end-users are going to be looking for that extra bump in network performance promised by the 802.11ac standard.

Next up, Tablet and notebook devices.

Congrats to Abe Peled for the Lifetime Achievement Award at Cable Congress!

This week in London, our own Dr. Abe Peled accepted the prestigious Lifetime Achievement Award from Digital TV Europe, as part of its “Euro 50 Awards” at this week’s Cable Congress.

Anyone who knows Abe knows that he’s a quick-witted, highly intelligent, super-motivated gentleman, and we’re all sincerely glad he’s part of the Cisco team, following our acquisition of NDS in 2012.

Abe has 40 years of accomplishments in the digital TV industry. He started his television life in 1974 at IBM’s Research Division, working on advanced digital signal processing techniques, and advanced up and up and up until he was named VP/Systems and Software, overseeing all of IBM’s research labs, worldwide. His work there even landed his face on a cover story in the New York Times’ Business section, in August of ’91. Read More »
