I've been busy over the last few days trying to clean up IRR information for our subnets and issue ROAs for our address space. Invariably I came across stale entries in various IRR databases. They aren't really hurting me, but I feel like there shouldn't be competing incorrect information out th

For anyone running Akvorado, can you please comment on resource requirements. I'm most concerned with CPU and memory, with the assumption that resources are somewhat linear to flow rate, but also curious about disk usage secondarily. Thanks, Graham

Experiences with commercial NOS vendors in white box space

Random Early Detect and streaming video

I've been involved in service provider networks, small retail ISPs, for 20+ years now. Largely though, we've never needed complex QoS, as at $OLD_DAY_JOB, we had been consistently positioned to avoid regular link congestion by having sufficient capacity. In the few instances when we've had link con
