For those that are not closely involved with IPv6, it may seem like the emphasis on migration to the new addressing scheme is waning. But while the hue and cry over IPv6 may appear to have quieted down to a background noise since 2010-2011; a closer inspection would prove that perception to be quite false.
What is IPv6 and why does it even matter? Simply put, when a device is on the Internet, it has its own specific address that it uses to communicate with other devices and the Internet and to define its location. With the non-stop growth of devices connecting to the Internet and the “Internet of Everything” (IoE) becoming a reality, the need for unique addresses for each personal device and machine-to-machine (M2M) connections has increased exponentially. To put this in perspective, the Cisco Visual Networking Index (VNI) 2013-2018 forecast estimates that there will be about 4 billion Internet users by 2018, which is 52% of the world’s projected population (7.6 billion people). And for every person on the Earth in 2018, there will be about 3 global Internet connections — that’s more than 21 billion devices/connections by 2018.The current communication and address format IPv4 was just not equipped for this explosive growth of devices and connections and the need to define addresses for each device. Hence the need for a new communication protocol, IPv6.

Cisco Wireless Release 8.0 is now available: Product Bulletin
The Cisco VNI Global Mobile Data Traffic Forecast, 2013 – 2018 revealed some stunning trends with growth projections that are sure to have a dramatic impact on wireless networks worldwide.
In 2013, globally, there were nearly 22 million wearable devices generating 1.7 petabytes of monthly traffic. There were about 7 billion mobile-ready devices and connections with mobile network connection speeds that have more than doubled, to 1.4Mbps up from 526 Kbps in 2012.
By 2018, there will be more than 10 billion mobile-ready devices and connections. The average mobile connection speed will nearly double, from 1.4 Mbps in 2013 to 2.5 Mbps and over 4.9 billion devices will be IPv6-capable. There will be more traffic offloaded from cellular networks (on to Wi-Fi) than remain on cellular networks.

Part 2 – Virtualized Services in an EPN World?
In part one of this series Gina covered the basic definition of an Evolved Programmable Network or EPN and its linkage to the Cisco Evolved Services Platform (ESP). Figure 1 offers a quick visual recap.
Figure 1: Cisco’s Open Network Strategy
And here’s a link to part one of this blog series if you need to play catch up.

A lot can change in 25 years. At the first Cisco Live (then known as Networkers conferences) in 1989, 200 geeks gathered for the inaugural event. Fast forward to three weeks ago, when we welcomed a whopping 25,000 attendees into the arms of our namesake, beautiful San Francisco.
We heard there was some interest in how the network performed at the show, so I wanted to share some of the interesting statistics about the network at Cisco Live! I shudder at the thought of the ancient network from 25 years ago. So here we go:
Wi-Fi Client Devices
This year we saw 30,705 unique devices, with 7000 in the theater for John Chambers’ keynote.
# of Unique Clients
# of Sessions
# of Unique Users
# of Unique APs
Avg Users per AP
Max. Concurrent Connected Wi-Fi Devices
There was a peak of 14216 concurrently connected device at SF this year.

Just recently I wrote about the IPv6 enabled logo program here at the Cisco Live 2014 World of Solutions (WoS). It is now time to share some of the results! In what follows I will say that I did not have enough time to exhaustively visit every single demonstration in the WoS. My time there was confined to a short window on the Tuesday morning, where I went to investigate and locate the IPv6 enabled demos myself.
Armed with my phone camera and IPv6 enabled logo stickers, I began my journey in the WoS starting with the Cisco demonstrations.
It didn’t take me more than a few steps to find the first one – Cisco Autonomic Networks. My colleague Amit Dutta was showing this technology in action and here you can see him alongside the demo which is tagged with the IPv6 enabled sticker. Check out the technology and the logo! Also leveraging the Autonomic feature set, Cisco was featuring the Autonomic Train with my colleague Toerless Eckert. Read his extensive blog that explains the demonstration in details and watch the video.
Another place in the Cisco campus where I found IPv6 in action was with the Cisco VIRL team. My colleague Joel Obstfeld was showing VIRL in action and v6 is fully supported by VIRL which was on clear show in the WoS. See Joel here alongside the VIRL demo and the IPv6 enabled sticker is on clear view.
onePK provides IPv6 capabilities and were demonstrating this. Jason Pfeifer is seen here alongside his demonstration on the Cisco stand bearing the IPv6 enabled logo.
Cisco Prime also has extensive support for IPv6. I found my colleague Gilles Clugnac demonstrating these capabilities and we identified his demonstration as being IPv6 enabled.
Then I talked to some of the Partners:
- Citrix Nestcaler provides server load balancing for IPv6 and provides an IPv6 proxy function that allows Data Centre’s and hosted web server to enable a dual stack presence. I met Charles and David on the Citrix stand and they showed me v6 in operation.
- APCON was showing their Network Monitoring technologies which were fully v6 enabled. Timothy Kcechowski showed me this in operation on the APCON stand and we placed the IPv6 enabled logo on their demo.
- Netformix has a suite of tools that have long supported IPv6 and they were also happily showing v6 in action. This picture shows Justin Giffen and Mario Oliver alongside the Netformix platform with the IPv6 enabled logo on display.
- SevOne provides Network Performance Management tools for Big Data. Jason Smith demonstrated this to me and here is his picture alongside their stand with the IPv6 enabled logo on display.
- Infoblox has a fully featured IPAM/DHCP solution and it is fully capable of IPv6 support. This platform was on display on the Infoblox stand and Ken Crozier showed me IPv6 in operation.
- Network Instruments provide Monitoring and Analysis tools. They were IPv6 enabled and received their sticker. Here you can see Charles Thompson on the Network Instruments stand alongside the monitor showing the IPv6 enabled logo.
I had a great time meeting old and new friends and spent many an hour in very interesting meetings trying to help move IPv6 forward inside our customer networks. I look forward to Cisco Live in Milan in early 2015 when I hope to be able to place more IPv6 enabled stickers. See you there!
