Course Summary:
This 4-day technical training course provides advanced training in Embedded Linux Networking and the design of networkign applications in Embedded Linux. The first part of the course focuses on The BSD Stack and Socket applications development in an Embedded Linux context with a focus on application performance measurement and improvement. The latter part of the course covers Packet Management in UDP and TCP, IPv6 and integrating open-source network protocols in Embedded Linux.
Who Should Attend
The course is designed for real-time engineers who are developing advanced networked Linux applications for Embedded Linux distributions. It is also targeted at experienced developers requiring a refresher course on Linux Network Device Driver development.
Course Objectives
- To gain an understanding of the Embedded Linux Networking Stack
- To provide an overview of Linux Socket application performance measurement and improvement.
- To provide a basic understanding of Packet Movement Up and Down the Network Stack.
- To gain an understanding of the complexities of Network Device Driver development
- To learn about common networking protocols and their uses in Embedded Linux systems.
- To give students the confidence to apply these concepts to their next Embedded Linux networking project.
