T minus 2 days

We have been working two full days now. We have internet, we have met some problems which have been solved in good time and we are still on track. The morale is high 🙂

Only two work days to go before TG13 is a reality…
http://tiny.cc/TG13-Countdown

We had to take the temp on the workers…

Different kinds of work equipment…

Working with the goods… 😛

But the focus is high to get everything done in time:

And then there is some who like to watch the green screen 😛

Jon is working hard with the DHCP and DNS preparations 🙂

And the discussions are many:

And the truth is that the ship is cold to work in without all the participants oO

Please! Come and warm us soon! 🙂

Our NOCGW core is up and running 🙂

And our TeleGW is up and running 🙂

And some interesting placements of the equipment are always called for:

And we have awesome new and fresh mouse pads 😀

Our awesome Tech:Support team is working with good mood and motivation 🙂

Lovely Mathias was taken off guard 😛

But when we came with good intentions, he gave us the grand tour 😀

Our lovely CrewCare chief and the worlds best participant ombudsman together 🙂

Packing the equipment (20.03.2013)

Soon… http://tiny.cc/TG13-Countdown

So the equipment is packed and made ready for shipment. Saturday everything will be shipped to Vikingskipet and we will start configuring the network 🙂

Packing securely:

And finding trolls behind the equipment 😛

Marking everything properly 😀

We <3 our sponsors 🙂

Not much space to move in:

Men at work 🙂

Fredrik is demonstrating how you use the “wrapping machine” 🙂

Pleased with the result 🙂

And since this is the same problem every year…

Dave Täht, Bufferbloat researcher, to visit

Dave Täht will be doing research at The Gathering on the size, and scope

of lag related network problems over the internet and wifi.

Cisco equipment testing – Day 2 (13.03.2013)

We are starting to sweat… we are closing in on TG (http://tiny.cc/TG13-Countdown) and there are still so much to do oO

But we are working on, enduring… and we will of course continue our work until we deliver the best network in Hamar 😉

Installing ESXi from a Linux computer was apparently a hassle:

Setting up our temporary network for the equipment was not 😛

FAIL! 🙁

But after a reboot, everything was in order:

And the cake was not a lie! <3 teh cake! 😀

Waiting for switches to boot, yet another time.
This time because of licenses:

And in the meantime we took our time to be in awe over a E1 card:

SO CUTE

People are tired of waiting for booting switches:

And finally we count the fiber patch cables:

I hope we counted right 😛

And we “labeled” our retro couch (in case of theft):

Cisco equipment testing – Day 1 (06.03.2013)

We in :Net had a testing session at Atea where we unwrapped all the equipment and tested it. This is of course necessary to check whether something was DOA and had to be replaced before TG. We are talking about days (http://tiny.cc/TG13-Countdown) before we have to travel up to Vikingskipet to start configuring the network. 🙂

The unwrapping of the equipment calls for some MacGyver skills;

And after unwrapping, we ended up with a hallway full of wrapping stuffs oO

HSN is looking for cables and transceivers (and bacon);

Martin are mounting the 4500s;

And finished mounting… result;

Running some tests;

Ok, ok… if you say so 😉

Peter (Organizer) approves the counting;

And we conclude this post with some pretty, fashionable switches wearing pink 😉

Tech Gathering – Design (02.02.2013)

We in the Tech crew had a social and technical gathering the second of February. We in :Net drafted the first version of the network design. From there could we discuss the design with :Support and :Server to get input from their point of view. We are 32 people in total in Tech which are 100% dependent on teamwork to be able to change something or introduce something new into the design.

We ended up with a lot of discussions, as usual;

Before we finally ended up with a draft we all could agree upon;

We met with the others after the network design session,
and people are patiently waiting for food;

Peter (Organizer) held a little status update, and open discussion after the food;

And discussions were flying high and low after people had filled their bellies 😛

And, as always, someone had to explain something on a napkin;
Help from SmartOptics \:D/

We in :Net are very lucky to have SmartOptics with us on our side.

We were desperate in need for WDM optical transceivers, and a couple of phone calls later they confirmed availability on the wavelengths we needed. But that’s not the best part. The best part is that they actually think TG is so awesome that they wanted to lend us the transceivers free of charge.

SmartOptics is a company specializing in high quality optical transceivers and WDM systems. One of their newest products is the embedded WDM system m:series ;

http://www.smartoptics.com/products/mseries/
This is a 1RU WDM system which supports everything from 100Mbps to 100Gbps, that scales up to a 200km reach and without the need for additional DWDM equipment. Aside from the obvious benefit from the pizza box design is the system very modular, with hot-swappable redundant PSU’s and replaceable network management module.

For more detailed information about the m:series system and pictures;

*A little bit general information about WDM:
*WDM is short for wavelength-division multiplexing. What it actually does is to combine more than one data channel through one fiber cable. You can for example push 16x fiber connections through one long range fiber cable. This possible because the optical transceivers “talks” on different wavelengths.

In general you have two different types of systems;

• CWMD (Coarse WDM) — the passive system that allows for a maximum of 20 channels between 1270nm and 1610nm with 20nm channel spacing.
• DWDM (Dense WDM) — the active system in its most common implementation allows for a maximum of 40 channels between 1554.54nm and 1586.62nm with 100GHz (about 0.8nm) channel spacing.

This is a picture illustrating how a WDM system works;

Cisco.. Neil deGrasse Tyson…

Neil deGrasse Tyson is talking about [the most astounding fact.. the universe

][1] (Graphical version)

And Cisco is talking about internet of everything

It’s not the same.. but still… it is, in a way

Everything is connected.. 🙂

Cisco + TG13 = awesome :)

We are very lucky to have Cisco with us as our main sponsor for TG13.
This year we are planning to implement the three-layer hierarchical design model (core, distribution, access), as illustrated in this picture;
