Some users are already hitting the 64k source port limit when connecting to servers. The system usually maintains a list of unused source ports, regardless of the source IP they're bound to. So in order to go beyond the 64k concurrent connections, we have to manage the source ip:port lists ourselves. The solution consists in assigning a source port range to each server and use a free port in that range when connecting to that server, either for a proxied connection or for a health check. The port must then be put back into the server's range when the connection is closed. This mechanism is used only when a port range is specified on a server. It makes it possible to reach 64k connections per server, possibly all from the same IP address. Right now it should be more than enough even for huge deployments. |
