Yes, you can in theory cause microbursting of UDP if you want. I am just
not sure which tool I would use to do that. Typical UDP tests like iperf
attempt to do perfect timing of packets so bursts are avoided, and they
seem to do a fairly good job of it.
Fair point. This is iperf:
if ( isUDP( mSettings ) ) {
...
delay_target = (int) ( mSettings-mBufLen * ((kSecs_to_usecs *
kBytes_to_Bits)
/ mSettings-mUDPRate) );
I still think UDP is the correct way to test network, making UDP burst (or not
burst) is easy, forcing TCP to behave as you desire is harder.
Quickly looking 'nuttcp 7.2.1' seems to support bursting,

Re: [j-nsp] Stackable switches, looping stacking ports
So I imagine that might help with latency, but is it going to have any affect on bit rate throughput?

A colleague of mine tells me that, if you have a single stackable switch (not in a stack obviously) and do not loop the two stacking ports on the back using the stacking cable that comes in the box, then you reduce the effective throughput of the switch. The ex4200's asic has a capacity of 136Gb/s from the front panel ports which is 100% of line rate across all ports. I don't imagine connecting the asic back to itself is that useful or usable topology. It does make a positive difference to loop back the stack cable on a standalone unit. See this diagram: http://blog.cochard.me/2010/08/juniper-ex-4200-internal-pfe-routing-in.html Connecting from ports 0-23 to 24-47 has to normally cross 3 internal PFEs. If you connect VCP-0 to VCP-1, then it only has to cross 2 PFEs. ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
