Real-Time Design Patterns: Robust Scalable Architecture for Real-Time Systems

Chapter 8. Distribution Patterns

The following patterns are presented in this chapter.

• Shared Memory Pattern: Using multiported memory to share global data and send messages

• Remote Method Call Pattern: Synchronous message passing across processor boundaries

• Observer Pattern: Efficient invocation of services with multiple clients

• Data Bus Pattern: Providing a common virtual medium for sharing data

• Proxy Pattern: Using the Observer Pattern between processors

• Broker Pattern: Sharing services when object location is unknown at design time

Introduction

Distribution is an important aspect of architecture. It defines the policies, procedures, and structure for systems that may, at least potentially, exist on multiple address spaces simultaneously. Distribution ...
