SRX and Bufferbloat

‎04-16-2019 01:30 AM

Hi guys


I am trying solve issues with internet connection on our branch offices (SRX 240). On every branch we experience packet loss and latency spikes when someone try download something from internet. From link measurement via dslreports i see very high bufferbloat. I tried configure firewall policer for download/upload limit (internet connection speed is only 30/30Mbit) and also CoS. With policer there was still some bufferbloat but even worse packet loss, with CoS everything was worse.


How do you manage bufferbloat on Juniper devices ? Is there something like Cake or fq_codel ( AQM/SQM) ?
