Introduction: Real-time processing systems are essential in many industries, including healthcare, transportation, and manufacturing. These systems require fast processing speeds and low latency to ensure timely responses to events or commands. However, designing and implementing such systems can be challenging due to factors such as limited resources, complexity, and security concerns. One solution to these challenges is the use of distributed real-time processing (DTP) systems, which enable efficient processing of large volumes of data across multiple nodes.
Fast Event Processor (FEP) is an open-source software framework developed for building real-time systems. It provides a high-performance event-driven architecture that enables efficient handling of events generated by input devices or other sources. The FEP architecture consists of three main components: event producers, event consumers, and event processors. Event producers generate events and send them to event consumers for processing. Event consumers consume events from event producers and perform necessary actions based on the event data. Event processors perform complex computations on the event data and generate output signals for downstream nodes.
The FEP architecture provides several advantages over traditional centralized systems, including reduced overhead, improved scalability, and better fault tolerance. However, designing and implementing a DTP system based on FEP requires careful consideration of various factors such as network topology, resource allocation, and security protocols. In this paper, we present the design and implementation of a DTP system based on FEP called "FEP-R" that addresses these challenges.
Design: FEP-R consists of multiple FEP nodes connected through a network interface. Each node has a local memory buffer to store incoming events and a local processor to perform computations on the events. The nodes communicate with each other via a shared memory area to exchange information and update their local buffers. The network interface provides a communication channel between the nodes and allows them to exchange events with each other.
FEP-R uses a simple yet effective algorithm for event processing called "event queueing." Each node maintains a queue of events that have been received but not yet processed. The node processes the events in the order they arrive in the queue, ensuring that each event is handled in the correct order. When a node becomes overloaded with events or encounters an error, it sends an event back to the event queue for later processing by another node.
FEP-R also includes several security measures to protect against unauthorized access and data breaches. The system uses encryption algorithms to encrypt sensitive data transmitted between nodes, and authentication mechanisms to ensure that only authorized users can access the system. Additionally, FEP-R includes built-in logging and monitoring capabilities to track system activity and detect potential errors or security threats.
Performance Evaluation: To evaluate the performance of FEP-R, we conducted simulations using real-world data from various applications such as surveillance, traffic management, and industrial control systems. The simulations involved generating synthetic events based on predefined rules and sending them to FEP-R nodes for processing. We measured several performance metrics such as throughput, latency, and response time to evaluate the efficiency of FEP-R.
The results showed that FEP-R could effectively handle complex real-time processing tasks with high throughput and low latency compared to traditional centralized systems. Furthermore, the system's scalability and fault tolerance capabilities made it suitable for use in various applications with varying requirements. For example, in a surveillance application, FEP-R could process thousands of events per second while maintaining low latency and high accuracy. In a traffic management application, FEP-R could adjust traffic signals in real-time based on sensor data while minimizing delays and congestion. In an industrial control system
