# UDT Implementation in C [](https://app.codacy.com/app/UtkarshMe/udt-c?utm_source=github.com&utm_medium=referral&utm_content=UtkarshMe/udt-c&utm_campaign=badger) An implementation of the **UDP-based Data Transfer (UDT)** protocol in C. UDT is a much faster data transfer protocol than TCP and provides a socket interface to send/receive data just like any other protocol. The documentation can be found in the header files (see `include/udt.h`). ### How to ```bash make # compile make clean # cleanup export LD_LIBRARY_PATH=./src/:$LD_LIBRARY_PATH # export the library path progs/server # start the server progs/client # start the client progs/sendfile # start the sendfile server progs/recvfile "file/to/get" "file/to/saveas" # receive the file ``` ### Progress - [x] Implement architecture. - [x] Implement basic API. - [x] Implement handshake. - [x] Use threads for sender/receiver. - [x] Implement data packet handling. - [x] Implement `sendfile`, `recvfile`. - [ ] Implement timer and use it to send various packets. - [ ] Make this work with an existing UDT implementation. - [ ] Implement a congestion control algorithm. ### Bugs, suggestions Please report bugs, suggestions [here](https://github.com/utkarshme/udt-c/issues). ### References - Yunhong Gu and Robert L.
