[Python-ideas] TAPS Implementation

2018-12-10 Thread Franke, Maximilian Julian Shawn
Hi, I am a student worker with the Internet Networks Architecture department at TU Berlin and I am working with APIs for network protocols. We are currently looking into implementing TAPS, a novel way to offer transport layer services to the application layer. The idea is to offer an API on
