We have a 4.9-RELEASE-p1 box dedicated to some traffic analysis. It monitors on two em interfaces: about 200,000 pps on one interface, and 180,000 pps on the other. It's been dealing with that OK, but our traffic levels are increasing - we reached over 240,000 pps on one interface last week. T

Hi, I'm having a confusing time trying to figure out why I can't get good throughput across a gigabit fiber run. I'm going to provide more details than is probably necessary to turn this email into something suitable to read as a bed time story. It all starts with two IMC media converters, a gig

I've done some local ports before and I know enough about multicast routing that I stand a chance of being able to come up with some suitable patches. I even have a good test environment for it here with Ciscos running PIM. I probably won't have time to come up with an extensive patch set, but I

I'm interested in doing IPv4 multicast routing but want to avoid DVMRP. I see kernel support for PIM both IPv4 and IPv6. But I can't find any user-level process to run PIM IPv4. It seems odd that kernel support would be present with no routing daemon. Am I missing something obvious? Th
