Advanced Networking

Programming on Linux
 

Course Overview

This course is designed for participants who are looking for a deeper understanding of Network Programming concepts on Linux. Participants expecting assignments on network protocol development or network application development will find this course extremely handy.

Key Takeaways

  • Look at widely used protocols on each networking layer and writing programs using them
  • Creating own protocol headers instead of Socket layer
  • Look at working with socket-layer-less environment
  • Detailed look at Linux Network Stack
  • IPV6 programming

Prerequisites

  • Basic C programming skills

Course Duration

  • 45 days
