Throughput and Bandwidth Measurer
This was a project I did when I was first getting into networking with Java. The intended use of the program is to choose what size packet you want to send over. The options are 8 bytes, 64 bytes, and 512 bytes. To measure round trip time (RTT) an acknowledgement is needed when the client receives a message from the server. In my program, this acknowledgement is the message itself. To measure throughput, I would send 1MB of data with the same message sizes. Meaning I would send 16384 8-byte messages, 4096 256-byte messages, and 1024 1024-byte messages. The results were that throughput increased as packet size increased and RTT increased as the message size increased. All of these messages were encrypted using a shared initial key that was updated using a custom random number generator every 64 bytes.
GoLang Agent and Server
This project consists of two separate programs. The Agent is a program designed to run in a Docker Container that by default will grab the top ten sightings from the Bird Sighting API and send that data to DynamoDB in AWS every hour. The Server program is also designed to run in a Docker Container, but a separate one from the Agent. This creates a microservice architecture, albeit on a smaller scale, and allows one program to be running even if the other does not. The Server will fetch all of the information in DynamoDB pertaining to the information gathered by the Agent and displays information depending on the endpoint that the user has reached.
File Transfer Using Sliding Window Protocol
This project is another networking one. This time I implemented a version of TFTP (stands for trivial file transfer protocol) using the sliding window protocol. I did this by using UDP over Java and measured different sizes of 'window' over different server/client pairs. I used a file size of 2.3MB. Through testing I found the throughput increased when given greater window sizes.
