ABSTRACT
We propose in this paper an extension to the token ring protocol that allows a special type of arithmetic, called shift arithmetic, to be performed directly on the nodes interfaces. The new protocol is based on the approach that the communication channel together with the interfaces can form an environment in which simple commands can be executed. Each command operates on operands located at the interfaces, and places the result at the interface that initiated the command. The commands utilize the mandatory 1 bit delay of the token ring protocol to implement arithmetic and logical operations on the operands without further delay. The goal of this protocol is to enhance the performance of distributed algorithms on ring networks by performing many simple tasks in the lowest possible level. We show that this protocol is especially useful for load sharing in local area networks since information such as minimal, average, and maximal loads can be easily found. Other potential application areas include parallel algorithms, distributed simulation, distributed operating systems, distributed databases, and real-time computations.
