Linux/AM57X: TCP performance in full duplex mode

Hi all!

I need information about the bandwidth of the network in full duplex mode. In wiki Bandwidth 1129.6 in full duplex?

Which processor of the Sitara supports the bandwidth in full duplex mode 1900-200 mbps?

The AM57x team have been notified. They will respond here.

Throughput benchmark from referenced wiki page are results from the standard iperf tool in the Linux environment, where Linux is running on ARM core(s) of the processor. the TCP throughput includes both source and destination ports (RX and TX), while the UDP benchmarks are separately listed as egress (TX) or ingress (RX). Ethernet ports from all devices support full-duplex, and are enabled as full-duplex ports when iperf runs.

On the requested "full duplex mode 1900-200 mbps", please further clarify if the question is regarding to raw throughput, or with a specified protocol.

Thanks for your reply. The question "full duplex mode 1900-200 mbps" is regarding to raw throughput.

No problem.
Note that all variants of AM572x and AM571x family devices support the 2-port Gbe switch subsystem. Each of the two external ports supports wirerate full duplex throughput, i.e. 1Gbit/s RX or TX full duplex.
please let us know if this addresses your inquiry.

1Gbit/s RX or TX full duplex.

Or? That is, sending and receiving cannot work simultaneously with a speed of 1 Gb / s each?

TX and RX CAN work simultaneously and each support 1Gbps.
