Best Effort QoS Drop Profile Input

Hello all,We are working on fine tuning drop profiles for customer edge routers (Juniper J-2320 in almost all cases) and I was hoping for some input from those who are smarter and have done this before.
Basics: - Sites each have a single T1 into a service provider L3 VPN - Queue depth is 500ms- Sites typically will use 90%+ of their line rate while school is in session (education network) - Services offered include: real-time video (in a different queue) and best effort (serviced by the queue in question)
- Nearly all BE traffic will be TCP (typical web, email, etc traffic)We were never able to find a good best practice for configuring drop profiles on edge devices. We've been using the following with OK results but I was hoping to have some external, more experienced eyes take a look...
drop-profiles { be_any { fill-level 50 drop-probability 5; fill-level 70 drop-probability 20; fill-level 90 drop-probability 50; }Has anyone ever run across a publicly documented best practice for drop profile configuration?
Does anyone have suggestions on ways to improve the configuration above? Any input is much appreciated, thanks in advance! -brad fleming
