* Setting a special feature on AAISP and the FireBrick - 'IP over LCP' - this sends the IP traffic as control frames. (high latency goes away)
* Setting a special feature on AAISP and the FireBrick - 'IP over LCP' - this sends the IP traffic as control frames. (high latency goes away). This IPoLCP is a niche feature and has been used in the past to help diagnose problems in back-haul networks: eg: https://www.revk.uk/2015/02/congestion-case-study.html
* Changing the DSCP value - only packets marked CS6 (192 to 195) are affected. Using values higher or lower and the latency goes away
