RUSHB Network Protocol Suite

Overview

Developed a complete network protocol suite for reliable data transmission, consisting of three components that work together to route data across a custom network architecture.

Components

• RUSHBSvr: Network server capable of sending and receiving messages using the custom RUSHB protocol
• RUSHBAdapter: TCP adapter bridging external processes (netcat, servers, stdin) to the RUSHB network
• RUSHBSwitch: Network router supporting both local subnet and global inter-network routing

Design Goals

• Lossless, error-free data transmission across complex network topologies
• Support for arbitrary data payloads attached through the adapter layer
• RFC-compliant protocol design with proper handshaking and flow control

Key Learnings

• Internet architecture design and component interaction patterns
• Communication protocol design across network layers (application, transport, network)
• Network security threat modeling and countermeasure implementation
• Protocol analysis using packet inspection tools (Wireshark)
