I'm looking for feedback that I am/not calculating my custom queue byte count the correct size. Below I've made up a circuit with a 56K cir and a port speed of 64K. Assume the carrier lets me burst to port speed.
My first question would be do I calculate the queue sizes based on cir or cir+be? I did the calculations below based on cir. I said I wanted to give 10% to WWW, 25% to DLSW, 25% to VoIP, and the remaining 40% to everything else. 56000 bits per second = 7000 bytes per second (56000/8) 7000 * .10 = 700 7000 * .25 = 1750 7000 * .40 = 2800 interface serial0.2 frame-relay class pointtwo map-class frame-relay pointtwo frame-relay traffic-rate 56000 64000 frame-relay adaptive-shaping becn frame-relay custom-queue-list 2 queue-list 2 protocol ip 1 tcp www queue-list 2 protocol dlsw 2 queue-list 2 protocol ip 3 list 180 queue-list 2 default 4 queue-list 2 queue 1 byte-count 700 queue-list 2 queue 2 byte-count 1750 queue-list 2 queue 3 byte-count 1750 queue-list 2 queue 4 byte-count 2800 access-list 180 permit udp any any range 16384 16484 access-list 180 permit tcp any any eq 1720 Going by a calculation I've read in the Slaterlee/Hutnik book (pg 481). To assign 75% of all bandwidth to one queue and 25% of the bandwidth to the other queue, they made two queues the first 7500 bytes and the second 2500 bytes and placed that queue on an ethernet interface. Those byte count numbers don't follow the bandwidth capacity of an ethernet interface. So, how did those figures get calculated? Another way I've seen these custom queues calculated: (in a training class I attended last month) Using the figures from my test scenario of 10% WWW, 25% DLSw and VoIP and 40% default. Using the default byte size of a queue, 1500 bytes. My 10% queue would equal 1500 bytes. 10%=1500bytes - WWW 25%=3750bytes - DLSw 25%=3750bytes - VoIP 40%=6000bytes - Default The first method I listed seems to make the most sense to me. This whole process has me confused as to which method is the correct method. Any help shedding light on this would be extremely welcome.
