Interprocess communication (IPC) is an important phenomenon in distributed computing and operating systems. Microkernels of modern operating systems use synchronous IPC semantics f...
The performance of the protocol stack implementation of an operating system can greatly impact the performance of networked applications that run on it. In this paper, we present a...
