Improving The stop-and-wait Protocol

We naturally ask 'Can the stop-and-wait protocol be improved?'

To answer this we first need to measure its performance to evaluate potential improvements.

Our protocols will always be subject to propagation delays and finite bandwidth - these cannot be overcome. However, our protocols will necessarily:

• add extra network traffic with frame headers,
• degrade an operating system with additional interrupts, and
• introduce delays in frame transmission.

Minimizing these overheads will help improve various efficiencies.
