TCP/IP Fundamentals

Understand the TCP/IP protocol stack that powers the internet. Covers TCP connection lifecycle, flow control, congestion control, UDP use cases, and practical networking knowledge for developers.

Usage

Ask about TCP/IP concepts, troubleshooting network issues, or understanding how your application communicates over the network.

Examples

  • "Explain the TCP three-way handshake"
  • "When should I use TCP vs UDP?"
  • "Why am I seeing TIME_WAIT connections piling up?"

Guidelines

  • Understand the TCP handshake for debugging connection issues
  • Use TCP for reliable, ordered delivery and UDP for low-latency, loss-tolerant traffic
  • Monitor TCP connection states to detect resource leaks
  • Configure TCP keepalive for long-lived connections through firewalls
  • Understand MTU and fragmentation for optimizing throughput
