Did you mean inetd/xinetd? systemd's .socket units are very similar (many existing programs, like sshd, can be moved directly from inetd to systemd -- Accept=yes corresponds to the 'nowait' type, and Accept=no to 'wait'), but since each . socket unit starts a corresponding . service unit, you get the same systemd features as with regular services -- dependencies, resource limits, process tracking, etc. On the other hand, there is no support for things like TCPMUX, SunRPC services (though Avahi integration was planned once), or some more obscure xinetd options. While both systems support both methods, systemd's socket activation is more often used to pass the *listener* socket to the service, which still does all accepting itself (e.g. both DBus and udev start this way); meanwhile, I see inetd more often used to start one instance per connection.
