Follow Internet2's Upgrade

Posted by michael on from the apt-get-install-internet2 dept.

An anonymous reader writes "This is a follow-up to this story posted several months back. Abilene, the backbone for Internet2, is starting its upgrade and has a webpage up to follow the installation. Looks like quite a few interestesting documents and photos. The first Juniper T640 router was installed in Indianapolis on Friday. Anyone who's interested in what goes into a nation-wide network deployment should check it out."

    Uhh, ipv6 is kinda the point of it anyway. The "Internet2" (also known as the "6Bone") _is_ the global ipv6 test network, after all. IPv6 is all it runs. Around my neck of the woods, its implemented as a mesh of SIT and GRE tunnels, but the backbone runs native.

    I wonder how many hops off of this shiny new hardware my poor little ipv6 GRE-tunnel sits...

    No, that is simply untrue. There is no connection between the 6bone and Internet2. They are certainly not the same thing. It's perfectly normal to speak IPv4 on Internet2. I do it all the time, as do most people who send packets between major .edu sites. Internet2 is the testbed for not only new software networking technologies, but new hardware technologies as well. There is no hardware involved in the 6bone.

    Here is a traceroute that goes over Internet2:

    Hop 6 is where my packets enter Internet2, and hop 15 is where it leaves it. There is no IPv6 spoken along the way. Now here, just for fun, is an IPv6 traceroute going over the 6bone:

    traceroute to 6bone.net (3ffe:b00:c18:1::10) from 2002:121a:12:1804:2a0:ccff:fe57:ccd9, 30 hops max, 16 byte packets

    Let me repeat that: Internet2 and 6bone are unrelated!

    noah

    The "Internet2" (also known as the "6Bone") [...]
    Internet2 and the 6bone aren't related at all.

    Incidentally, we run both IPv4 and IPv6 on our Abilene backbone.
