Random early detection (RED) is a queuing discipline for a network scheduler suited for congestion avoidance.
This implementation is based on the Go-Back-N protocol implemented in: https://github.com/kymmt80/GoBackN-Protocol.
Any number of senders can connect to the router. Due to the possible high number of messages, RED is used to avoid congestion.
Each sender, reads content from test/francais.txt and sends them to the router R in chunks of size 1500 bytes. The router stores each received frame in its buffer unless the buffer size exceeds a specified number. In this case, the router drops the received frame with probability P, where P is a linear function of the current queue-length. Upon receival (:-?), receiver B sends an acknowledgment (ACK) for each packet received. Sender A, detects if a packet is dropped by the router using some mechanism, and re-transmits as specified in the Go-Back-N protocol.
First, make sure you are in the main directory of the repository. Then, run the following commands:
$ cd test/
$ bash run_tests.sh
