PGM about netmq HOT 6 CLOSED

I found the following info on the openpgm website:

OpenPGM can interoperate with Microsoft's
PGM implementation found in Windows XP
and newer platforms, hence called MS-PGM.
Microsoft's stack is currently limited to
PGM/IPv4, with no support UDP
encapsulation or IPv6.

Imo we should try that out first and the emcaster example suggests that it is not very difficult.

I guess using the openpgm implementation from .net and mono is somewhat more complicated but for portability we should definitely keep that in mind and finally have that on the roadmap.

IIRC MS implementation of PGM suffers from not having a push-back. If data are sent faster than they can be pushed to the network the memory usage grows without bound. However, this is a pretty old observation (~4 years old), the problem may have been fixed in the meantime. You should check before spending too much time on it.

@sustrik how can we test that?

Just push data to PGM socket as fast as possible and check whether it will completely exhaust the memory.

thanks.

pgm is working :-), still have some stuff to complete so i'm not doing pull request yet.
it should be compatible with zeromq openpgm.

implemented with ms-pgm. if you want to take a look you can find it at:
