| 1 | This directory contains an RTEMS application for measuring TCP/UDP |
|---|
| 2 | network throughput. The ttcp_orig subdirectory contains the original |
|---|
| 3 | UNIX program which can be compiled and run on your host machine. |
|---|
| 4 | |
|---|
| 5 | The RTEMS version of the test program is a little clumsy to use. You |
|---|
| 6 | have to edit the rtems_ttcp.c source file and change the ttcp_argv |
|---|
| 7 | array of strings to set the arguments you want passed to the ttcp |
|---|
| 8 | task. |
|---|
| 9 | |
|---|
| 10 | It does work, though. The best throughputs I've seen so far are: |
|---|
| 11 | 68360 card can transmit a TCP stream at 198 kbytes/second. |
|---|
| 12 | 68360 card can receive a TCP stream at 119 kbytes/second. |
|---|
| 13 | In both cases, the other end of the transfer was a 486DX2/66 running |
|---|
| 14 | OPENSTEP/MACH 4.1. |
|---|
| 15 | |
|---|
| 16 | One noteworthy item is that I was able to get the UNIX test program |
|---|
| 17 | running under RTEMS with no changes to the test program itself. The |
|---|
| 18 | entire UNIX source file is included, without changes, into the RTEMS |
|---|
| 19 | source file. |
