This project implements a reliable TCP receiver from scratch, designed to handle byte-stream communication and manage out-of-order segments. The project is broken into three core components: ByteStream, Reassembler, and the final TCP receiver that integrates both.

1. ByteStream: A container for managing the writing and reading of bytes with defined capacity, ensuring bytes are stored and accessed in the correct sequence.
2. Reassembler: Responsible for assembling the received byte segments into a contiguous byte stream, even if the segments arrive out of order.
3. TCP Receiver: Combines the ByteStream and Reassembler, handles TCP sequence numbers, and sends acknowledgment (ACK) and window size to manage data flow.

• ByteStream: Implements a simple data structure for writing and reading bytes. It handles memory limitations and ensures efficient byte handling.
• Reassembler: Assembles TCP segments, keeping track of missing bytes and discarding segments that exceed capacity.
• TCP Receiver: Manages the communication with the sender, including handling the sequence number wraparound and generating acknowledgments.

1. Download and extract the zip file.
2. cd into the project directory and create a new directory called build.
3. Now cd into the build directory and run cmake .. to configure the project.
4. Once the project is configured, run make in the same directory to build the project.
5. Once the project is built without any errors, you can run ctest to run all the tests for the TCP receiver.
