Uses Mach's [[IPC]] [[mechanism]]. The [[port]] abstraction allows RPCs to be executed on another computer transparently. This can be implemented with user [[task]]s, but there is an implementation in the kernel possible, too, which is called *NORMA*, but is not avilable in [[GNU Mach|gnumach]]. The RPC stub code is generated by [[MIG]] to send appropriate [[message]]s. # Tracing * [[hurd/debugging/rpctrace]] * [[open_issues/librpci]]
