[mpls-linux-general] Testing with Iperf

[Miquel C. P. <u10...@co...>]

Hello,,

I have the next structure and run under mpls perfectly,

prefix: 192.168.x.x

host_1(LER) <----> host_2(LSR) <----> host_3(LSR) <----> host_4 (LER)
on x.x=   0.1   0.2          3.2    3.3         2.3    2.4

 I am testing the transfer speed with Iperf. I run server of iperf to
host_4,, and in host_1 run the client, my results is the next:

On MPLS:

[root@uni ~]# iperf -c 192.168.2.4 -F prova.rar -f M -t 30
------------------------------------------------------------
Client connecting to 192.168.2.4, TCP port 5001
TCP window size: 0.02 MByte (default)
------------------------------------------------------------
[  4] local 192.168.0.1 port 32772 connected with 192.168.2.4 port 5001
[  4]  0.0-30.0 sec  29.4 MBytes  0.98 MBytes/sec


And I disable mpls, the results is:
On IP:

[root@uni ~]# iperf -c 192.168.2.4 -F prova.rar -f M -t 30
------------------------------------------------------------
Client connecting to 192.168.2.4, TCP port 5001
TCP window size: 0.02 MByte (default)
------------------------------------------------------------
[  4] local 192.168.0.1 port 32780 connected with 192.168.2.4 port 5001
[  4]  0.0- 8.0 sec  89.1 MBytes  11.1 MBytes/sec



It is normal???? I think that on mpls the packets more speed that IP,
because the forwading is realise on layer 2 (OSI).
What is it???? Something explanation?


thank you;;
