[Bloat] new network deploy

[Luca Dionisi <luca.dionisi@gmail.com>]

Hi all

I am starting to deploy a local TCP/IP network in order to test a new
routing protocol.
Info on the routing protocol: www.netsukuku.org
Info on the network being deployed: pyntk.blogspot.com
It is separated from the Internet at the moment.

I ask for advices on how to make it as free as possible from the
bufferbloat problem.
I would also make some tests on this network and report here what I
find out about bufferbloat.

Further information:
 * every node active on the network will be a modern linux host.
 * all of the links between nodes will be on wifi or on cables owned
by the users. That is, no VPN links over the Internet.
   * if it is needed I can list the actual chipset of ethernet cards
and radio devices.
 * most of the wifi links will be managed by radio chipset installed
in linux hosts (mostly ad-hoc, no strange do-it-all out-of-control
embedded-router-bridge-repeater devices)

There is also a particular case. Two linux nodes are connected via a
VPN at layer 2 (I use tinc) over another network with static addresses
and routing. This network is formed by the 2 linux hosts and 2
embedded radio devices, from Ubiquity, which run AirOS, a derived of
OpenWRT.
In this particular case, where do I have to look for possible buffers?
Is it enough to look the tx-queue of the virtual nic or do I have to
check also the settings of the Ubiquity devices?
