UDP multicast allows the transmission of data to multiple receivers with a single send operation. This project involves creating a sender application that multicasts data packets to a designated multicast group and a receiver application that listens to this multicast group and processes the received data.
- Operating System: Linux (preferred), Windows, or macOS
- Network: Support for UDP and IP multicast
- Programming Languages: Rust, Go, or Python (as per developer preference)
- Tools: Docker, Helm (for containerization and orchestration)
Functional Requirements:
- Join a specific multicast group.
- Send data packets to the multicast group at regular intervals.
- Support for configurable multicast address and port.
- Option to specify the interface for multicast transmission.
- Graceful handling of termination signals (e.g., SIGINT, SIGTERM).
Non-Functional Requirements:
- High performance and low latency.
- Scalable to support large volumes of data.
- Minimal resource consumption.
Functional Requirements:
- Join a specific multicast group and port.
- Listen for incoming multicast packets.
- Process and display/log the received data.
- Support for configurable multicast address and port.
- Option to specify the interface for multicast reception.
Non-Functional Requirements:
- High performance and low latency.
- Ability to handle packet loss gracefully.
- Scalable to support multiple receivers.
Choose one of the following languages based on the team's expertise and project requirements:
- Rust: High performance, memory safety, and concurrency support.
- Go: Simplicity, concurrency, and strong performance.
- Python: Ease of use, rapid development, and extensive libraries.
For each language, use the following libraries to simplify development:
- Rust:
tokiofor asynchronous networking,miofor I/O handling. - Go:
netpackage for networking. - Python:
socketandstructmodules for networking and data handling.
- Multicast Address: Use an address in the range 224.0.0.0 to 239.255.255.255.
- Port Number: Choose an appropriate port number (e.g., 5000).
- TTL (Time to Live): Configure TTL to limit the multicast packet's network reach.
- Interface: Ensure the network interface supports multicast and is properly configured.
- Implement robust error handling to manage network failures, invalid configurations, and unexpected termination.
- Use logging libraries to record significant events, errors, and status updates.
- Rust:
logandenv_logger. - Go:
logpackage. - Python:
loggingmodule.
- Rust:
- Unit tests for individual components (sender and receiver).
- Integration tests to verify end-to-end multicast functionality.
- Performance tests to measure latency, throughput, and resource usage.
- Simulate network conditions to test resilience and error handling.
- Containerize the sender and receiver applications using Docker.
- Use Helm for orchestration in Kubernetes environments.
- Provide deployment scripts and configuration files.
- Validate and sanitize all inputs.
- Ensure multicast data integrity and authenticity.
- Implement access controls and restrict multicast group membership.
- Provide comprehensive documentation for installation, configuration, and usage.
- Establish a support plan for troubleshooting and updates.
- Regularly update dependencies to address security vulnerabilities and performance improvements.
