Course Overview

This course focuses on the application of TCP/IP protocol in satellite communications. Participants will learn how TCP/IP has accelerated the digital scenario and the basics of IP in satellite communications, including the techniques to ensure the functioning of a two-way satellite service.

The course will cover the performance of IP over satellite networks, including the challenges faced in the delivery of reliable and fast data. It will also address the technical difficulties faced in satellite communications (e.g., latency, jitter, error rates) and the solutions available to overcome these issues. Additionally, the impact of transport protocols on satellite links and the performance of TCP and UDP over satellite networks will be covered.

This comprehensive course is designed for network engineers, system administrators, and anyone involved in managing or operating satellite networks. It includes hands-on workshops to analyze packets via Wireshark and practice networking commands via the Command Prompt.
