[Olsr-dev] Strategy for ETT metric

[Henning Rogge]

Hello,

I'm working on a wrapper for olsrd to include layer 2 information into my 
routing plugin system. I have looked through some papers about ETT and the 
only sollution to measure link bandwith seems to be the to send small unicast 
packages along each 1-hop link (unless there is other traffic on this link).

I see two options to do this:

1.) wait for some time, then send one package to every 1-hop neighbor

2.) distribute the packages over time

Option 1 does wake up the olsrd one once for all neighbors, but it sends a 
burst of packages that might block some real traffic.

What do you think about the two options.

(I don't will use "packet pair" algorithms, just reading the bandwidth from 
the wlan card when receiving the unicast package)

Henning
