5ms vs 2.5ms on PTP 450i

Hello,

on ePMP line you can set 5ms if you want higher throughput but higher latency, and 2.5ms with little bit throughput and lower latency.

I expected it to be the same on PTP 450i, but, same RF conditions (lab), with 5ms on 30MHz channel I can test ~ 150Mbps aggregate and 2-3ms round-trip latency, and with 2.5ms I can test ~206Mbps 1-2ms round-trip latency.

Is that normal? What should I expect with 2.5ms and 5ms?


Thank you!

Hello,

I noticed a message saying using 5ms each VC can have max 51Mbps throughput.

Here's what I can do with 5ms and "High and Low Priority VCs".

It says 230Mbps aggregate, but if I try to do iperf or other test (even UDP) between the link I can test about 150Mbps downlink and 55Mbps uplink. Why?

Signal is perfect and high, the link is very very short (it's a test).

Thank you

Hiya!

your radios move same as mine . Check your percentage downlink.i dont think these have the flexible type setting as epmp  just a percentage amount adjustment

Yes, they only have a percentage amount for ratio. Flexible isn't there.

The strange thing here is the link test reports 230Mbps aggregate, but I can only test about 200Mbps aggregate.
