Re: OT: QOS on Signaling Traffic for Mobile operators, SIGTRAN,

Hello Radio,
                    Thanks , but i think if i used priority for the
signaling queue i will be using 2 queues ( Voice & signaling),
                   2 LLQs in CBWF Or to be more specified i will be using 2
priority queues on MDRR for the GSR & CRS-1

  I remember reading about this in one of my QOS references, but did it
scale well with you, did it give you the preformance for both voice &
signaling ?

The Signaling requires min delay, RTD of 50 ms & 100 ms. !!!!!

Thanks in advance.
