SRX

Hi,

What is the best way to configure a low latency queue on the high end SRX.  On Branch and switches I can do the following:

set class-of-service schedulers voice-network-sched shaping-rate percent 15
set class-of-service schedulers voice-network-sched buffer-size percent 15
set class-of-service schedulers voice-network-sched priority strict-high

On High end (SRX-3600) shaping-rate is not supported and I have to use transmit-rate

set class-of-service schedulers voice-network-sched transmit-rate percent 15
set class-of-service schedulers voice-network-sched buffer-size percent 15
set class-of-service schedulers voice-network-sched priority strict-high

I am worried that with transmit rate my voice queue could eat up all the bandwidth of the link where shaping rate limited the queue.

Hi ttl_expired,

The method you are using on the high-end SRX is actually a better way to do this.  Anything that exceeds 15% of the transmit rate for that forwarding class will be dropped.

This will prevent your strict-high queue from starving lower priority queues.

Hope this helps,
