pl is a very simple packet loss manager

There is a server and a client

• The server will be listening for [[tcp]] connections.
• The client will connect to the server via tcp and tell it:
  • I'm going to send you 100 [[UDP]] packets over the next 5 seconds.
  • Please listen out for them and count how many arrived.
  • Afterwards please tell me how many arrived.
• The server will say:
  • I received x UDP packets from you
  • I will also send you 100 UDP packets.
• Then the client will count how many UDP packets arrived from the server and present the information: loss on the way there, loss on the way back, total loss

Rationale

I built this project to familiarize myself with

1. Linux syscalls, particularly: UDP and TCP sockets and interprocess communication
2. fork-join parallelism
