Re: [mpls-linux-general] mpls-linux speed test.

HI,

1. Pim, can you be more explicit about your results please? I'm afraid I =
don't=20
understand the two collumns. I think you posted some similar results on y=
our=20
ds-mpls mailing list but I was not paying attention at that time. :)
Thanks.

2. Regarding my previous tests:
  Although the MPLS forwarded all the frames, since the source was transm=
iting=20
at a speed close to the maximum 100Mbps and due to the extra traffic indu=
ced=20
by the MPLS shim (32 bits/packet), eth1 was not able to send out all the=20
packets. My mistake was when I red the statistics about the received data=
=20
(bit/s) and not packets received.

Here are the results for a sample of 523001 sent packets. The receiver on=
ly=20
got 521042 =3D> 1959 packets were lost.
This was not due to the MPLS engine but because of the extra traffic adde=
d=20
with the MPLS shim.

Regards,=20
