All things related to multicast

[Ladislav Lhotka <>]

Hi all,

I have forward-ported this IGMPv3 patch to compile cleanly and work with
Linux kernel 2.4.19. It can be obtained from
http://www.cesnet.cz/tf-ngn/multicast/ssm/

At the same site you will also find a simple SSM application that we
currently use for SSM tests in GEANT/TF-NGN.

Best regards,

Lada
