RPC in the x-Kernel: evaluating new design techniques

摘要: This paper reports our experiences implementing remote procedure call (RPC) protocols in the x-kernel. exercise is interesting because RPC exploit two novel design techniques: virtual and layered protocols. These techniques are made possible x-kernel provides an object-oriented infrastructure that supports three significant features: a uniform interface to all protocols, late binding between protocol layers, small overhead for invoking any given layer. For each technique, motivates technique with concrete example, describes how it applied implementation of presents results experiments designed evaluate technique.
