Hi Patrik, Many thanks for the reply. It really helps a lot. Can you please put some comments on the following configuration. Just to avoid jitter, I'm keeping the voice queue small. voice-profile fill-level 0 drop-probability 0; fill-level 25 drop-probability 100;
transmit-rate percent 20 exact; buffer-size percent 20; priority high; drop-profile-map loss-priority any protocol any drop-profile voice-profile; Is this good on Gig interface for Voice. What is exactly this file-level with drop-probability. -----Original Message----- From: Patrik Olsson [mailto:[email protected]] Sent: Friday, May 01, 2009 10:26 AM To: Andrew Jimmy Cc: [email protected] Subject: Re: [j-nsp] forwarding class nd loss priority Hello, schedulers and schedulers-map is to schdule traffic egress. The scheduler decides how much bandwidth a forwarding class gets. Ingress forwarding class is decided and also a drop priority ion case the traffic needs to be dropped. In the scheduler within a forwarding class different drop-priorities can be treated different through applying different drop profiles. When it comes to voice, it should have it's own forwarding class of a high priority. It should not be using different drop priorities and different drop profiles. It should have one that says: drop everything if you need to queue. Because voice traffic dont like to be queued and sent later. It will mess the sound up. In return voice traffic should have the highest priority and whatever bandwidth it need to push any other traffic away.
