Loading...Introduction to Space Communication Protocols
When it comes to space communication, reliability and performance are crucial. Last quarter, our team discovered that the CCSDS File Delivery Protocol (CFDP) and Delay-Tolerant Networking (DTN) are two protocols often considered for such applications. Here's what I learned when comparing these two protocols for a project that required transferring large files between spacecraft.
Overview of CCSDS File Delivery Protocol (CFDP)
CCSDS File Delivery Protocol is designed for reliable file transfer over space links. It's particularly useful for deep space missions where communication delays are significant. I realized that CFDP's strength lies in its ability to handle large files and provide reliable transfer even in the presence of errors or disconnections.
Overview of Delay-Tolerant Networking (DTN)
Delay-Tolerant Networking, on the other hand, is an approach to networking that emphasizes store-and-forward message switching.
