Learn how to build a robust ARP cache module in C that handles packet queuing, request deduplication, retries with exponential backoff, and ICMP error generation for unresolved ARP requests.
Dissecting the `sr_handlepacket()` function from a production-grade router implementation, this tutorial demonstrates how to build a stateful packet processor in C that handles Ethernet, ARP, IP, and ICMP protocols with zero-copy parsing, deferred work queues for ARP resolution, and longest-prefix matching for routing decisions.
Implementing the Routing Information Protocol (RIP) in C, demonstrating how routers automatically discover network topology and compute optimal paths using the Bellman-Ford algorithm, while handling real-world constraints like binary protocol compliance, network byte order, and UDP checksums.
Building a production-grade network router that implements the Routing Information Protocol (RIP) using low-level C, integrated it with Software-Defined Networking (SDN) through OpenFlow, and packaged everything into an interactive, browser-based simulation environment.
A deep dive into building a production-grade network router using C, Mininet, OpenFlow, and Flask, all within a Docker container. Learn how to implement core networking protocols, software-defined networking principles, and a browser-based terminal interface for interactive learning.
