Version:			1

Project ID:			3

CS Class:			CS 3516

Programming Language:		C++

OS/Hardware dependencies:	GNU/Linux, network interface

Problem Description:		Create a program that sends a file across an overlay network

Program Assumptions and Restrictions:

	File size must not be a multiple of 1000 bytes

	Config file must be valid

	Routers and end hosts must be running to transmit files

Interfaces:	 Command line interface

Implementation Details:

	Hosts and routers use busy waiting to wait for packets

	Maximum payload length for an individual packet is 1000, not including overlay headers

	

How to build the program:  make

Results:

In this example, the overlay network was configured to intentionally drop a packet.

---Sending host---

> ./overlay

File transmitted.

Size: 3883 bytes.

Packets trasmitted: 4

---Receiving host---

> ./overlay

Missing packet ID: 2

File received:

Length: 2883

Packets received: 3

When not configured to drop a packet:

---Receiving Host---

> ./overlay

File received:

Length: 3883

Packets received: 4
