An anycasting protocol for anonymous access to a group of contents-equivalent servers in a distributed system

Abstract

A novel anycasting protocol for timed asynchronous distributed multiserver systems is proposed. It is based on an anonymous multicast communication in a network of servers. In contrast with known approaches, the task of selection of a server in the given group is shifted from clients and the network to the servers that make a selection decision themselves as a result of a negotiation. The protocol was investigated with the use of a detailed simulation model using a class of the extended Petri nets. The results of simulation study of the proposed protocol are compared to the behavior of an ideal, centralized multiserver queuing system.
