The Internet routing table size has continued to grow steadily. In 2008 we reached 256K routes and now the table has exceed 512K Routes. This is of significance for customers running some of the older PFC3 based Supervisor 720 engines on the 6500 and 7600 switches.
On the Catalyst 6500 and 7600 Series platforms, all of the routing information is stored in special high-speed memory called TCAM. Read More »
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.
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.
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:

This year we saw 30,705 unique devices, with 7000 in the theater for John Chambers’ keynote.
