Assignments:

  1. UDP Socket: Get familiar with datagram sockets using POSIX C programming. The target is to establish a communication between two computers (processes) using datagram socket. A datagram socket uses a simple communication paradigm to transfer short messages between two computers (processes) without ensuring any reliability

  2. TCP Socket: Get familiar with stream sockets (also called TCP sockets) using POSIX C programming. A stream socket establishes a connection between the client and server, which remains there until one of them closes it (explicitly or implicitly on exit). The connection can be used to transfer ordered sequence of bytes between two computers (processes) reliably

  3. Concurrent TCP Server: Implement a concurrent server where multiple clients can requests for same or different services and the server serves them concurrently. The implementation will help you to understand the functionality of the ​ select() system call used for servicing multiple requests over different sockets

  4. Simplified File Transfer Protocol (FTP): Implement a simplified version of the file transfer protocol. The subset of the commands that you have to implement is small, FTP has a much richer functionality.

  5. File Transfer in Blocks: Transfer files between two hosts with block based transfer. We’ll learn a special flag in recv() call named MSG_WAITALL.

  6. Non-Blocking I/O: Implement a concurrent server where multiple clients can requests for same or different services and the server serves them concurrently with the help of nonblocking I/O operations.

  7. Reliable Communication over Unreliable Channel: Build support for reliable communication over an unreliable link. The unreliable link will be implemented with a UDP socket.

  8. Traceroute: Implement mytraceroute -- your version of the Linux traceroute tool for identifying the number of layer 3 (IP layer) hops from your machine to a given destination.

  9. Signal Driven I/O: Simple UDP echo server using asynchronous, non-blocking I/O.
