31C3 CDN-Support

Just as last year the C3-VOC is looking forward to your support for the upcoming congress, helping us to provide the outside world of the Congress with live streams from lectures and events of the 31C3!

The topics you could help us out most are Live-Streaming and Providing Releases.

Topics

Streaming Relays

The Streaming Relays are used for the distribution of live streams. Mainly we need here systems with lots and lots of network bandwidth to be able to serve the expected 6000 spectators. Since we will stream all rooms in FullHD this year and thus the number of viewers that can be handled from a single server drops significantly, we plan to build, compared to last year, an even larger CDN. For additional server resources, we are therefore particularly grateful this year.

Access to the appropriate systems is required as early as possible, but not later than 15th December 2014 and until 30th December 2014. They will generate noteworthy load between 27th and 30th December.

Hardware

Whether you can provide virtual or real hardware resources, we have the following minimum requirements for the deployed systems:

2 CPU cores

2GB Ram

1 GBit network interface with IPv4 and IPv6 connectivity

100GB hard drive

==== NetworkIt is easiest if the relay is not firewalled externally and we can handle that locally ourselfs. If your network infrastructure requires a whitelisting, at least the following ports must allow incoming TCP connections:

22 (SSH)

80 (HTTP)

1395 (RTMP)

8000 (Icecast)

==== SoftwareWe have an installation medium prepared that installs an adapted system on your hardware / VM. You will receive this as soon as we have agreed upon the requirements of your Relay. The installation is fully automated, if the network configuration can be done via DHCP, otherwise the installer asks for an IP address.In automatic the first disk found will be partitioned and - without further question - completely formatted. Soft-Raid configurations require manual interaction during the installations. Please contact us at 31c3-cdn@c3voc.de in such a case or in case other issues occur during installation.

Recording mirrors

The final releases of the lectures will this year again be published directly to http://media.ccc.de and distributed from there.

Distribution via HTTP
