Internet Milestone: 30th Anniversary of ARPANET transition to TCP/IP
New Year's Day Marks 30th Anniversary of Major Milestone for Global Internet 1 January 2013 -- Thirty years ago today on 1 January 1983, the ARPANET, a direct predecessor of today's Internet, implemented the TCP/IP protocol in a transition that required all connected computers to convert to the protocol simultaneously. The open TCP/IP protocol is now a foundational technology for the networks around the world that make up the global Internet and interconnect billions of devices. The transition, which was carefully planned over several years before it actually took place, is documented in the Internet Engineering Task Force (IETF) RFC 801 authored by Jon Postel. Throughout its history, the Internet has continued to evolve. Today, deploying IPv6, the latest generation of the IP protocol, is critical to ensuring the Internet's continued growth and to connect the billions of people not yet online. Thousands of major Internet service providers (ISPs), home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6 for their products and services through efforts such as World IPv6 Launch organized by the Internet Society. For more information about the Internet Society's work to facilitate the open development of standards, protocols, and administration, and to ensure a robust, secure technical infrastructure, see the Internet Technology Matters blog and the Deploy360 Programme. For further details about the Internet's history and development, see the "Brief History of the Internet".
It's incredible that TCP/IP has survived this long. It's a testament to the well thought RFCs that spec'd it out. Pop Quiz. 1) What's the TCP handshake? 2) How does TCP manage to saturate the link provided by a 9600 baud modem and with very little tweaking a 10Gbit link? 3) Assuming a hypothetical gigabit link between your house and your end-point of interest is 1000kms, and the speed of light on fibre is 2/3 c (speed of light in Vacuum) and a 0.5 ms delay due to optical switching, can you calculate the RTT for the link? 4) Once you have the RTT from 3 above. Calculate the bandwidth delay product of the link <<< Hint: This calculation gives you the buffer size settings that you should adjust on your TCP stack. Linux users can check out /proc/sys/net/* 5) How does traceroute work? << Hint: Trickery using TTL and ICMP error messages As an aside, you may not know it but I think it's easier to roll out IPV6 than IPV4. Really, with router advertisement, it's painless. On Tue, Jan 1, 2013 at 7:37 PM, Michuki Mwangi <michuki@swiftkenya.com> wrote:

True ipv6 is easier once you get through your brain trying to figure out hex and 128bits. Unfortunately it's developers on the tail end of this one. There are a few tweaks to the socket api. There is a book http://www.amazon.com/Network-Programming-Jun-ichiro-itojun-Hagino/dp/155558... that I found very informative. I think we make this the year that kenya takes the lead ipv6 adoption. We have all the necessary resources to make that happen. Jgitau Sent from my iPad On 2 Jan 2013, at 21:40, Laban Mwangi <lmwangi@gmail.com> wrote:
