GoBGP: BGP Implemented in Go
This is the sort of thing Go really shines on: network and infrastructure services that would ordinarily be provided by big ugly C programs, where the latency requirements are significant but not as bad as raw packet forwarding. If your current best alternative is a C program, I'm not sure why you wouldn't seriously consider replacing any of the following with Go (or Rust) programs:* Authority DNS* DNS caches* ntp* SMTP* SSH* IMAP (added later)* SNMP* PBX/TelephonyFortunately, as time goes on, fewer and fewer people need to run these services at all.
