Design and Implementation of Communication Method for Multi-Process DNS Server

Multi-process technology is an effective method to deal with software complexity.This paper proposes a multi-process communication method, which includes a multi-process communication protocol and the design of a communication interface and a message router daemon.CI uses SSL protocol to keep security, MRouter uses message forwarding mechanism to achieve point to point and point to multi-point communication.This framework has already been used in BIND10 project.It can finish real-time communication between any processes, support distributable deploy, keep fault tolerance and robustness, be convenient to extend.
