|
burble.dn42 is an experimental global network within [DN42](https://dn42.dev).
|
|
|
|
The network is well [connected](https://map42.0x7f.cc/) with a large number of
|
|
peers, and hosts some of the [DN42 core infrastructure](/services/dn42).
|
|
|

|
## Topology
|
|
|
|
{{<hint info>}}
|
|
Dec 2021 - The burble.dn42 network is being re-designed !
|
|
More details coming soon.
|
|
{{</hint>}}
|
|
|
|
*Previous design*
|
|
|
|
All nodes in the burble.dn42 network are fully meshed with wireguard tunnels.<br/>
|
|
iBGP with [BGP Confederations](https://en.wikipedia.org/wiki/BGP_confederation) and
|
|
a latency based metric are used as the interior routing protocol between nodes.
|
|
iBGP is also fully meshed. and the configuration for both iBGP and wireguard tunnels
|
|
is built using a number of [Ansible](https://www.ansible.com/) scripts.
|
|
|
|
The current network design was introduced in December 2019; previous designs for
|
|
the network have included a VXLAN overlay over the wireguard mesh to create a
|
|
single layer 2 network, together with the use of OSPF as the
|
|
IGP. Other variations have included using BABEL, and tinc.
|
|

## Core Technologies
|
|
|
|
A selection of key technologies used within the network
|
|
|
|
- [Ubuntu](https://ubuntu.com) - node operating system
|
|
- [Bird2](https://bird.network.cz/) - routing daemon
|
|
- [LXD](https://linuxcontainers.org/lxd/introduction/) - for virtualisation and containers
|
|
- [Packer](https://www.packer.io/) - for container builds
|
|
- [Alpine Linux](https://alpinelinux.org/) - used for containers
|
|
- [Ansible](https://www.ansible.com/) - for deploying configuration
