Question

Suppose we provide a new implementation of the transport layer protocol tcp providing the same functionality using different algorithms. ⢠how does this impact operations at the application layer? ⢠how does this impact operations at the network layer?

Answer 1

If properly implemented, the API's (Application Programming Interface) won't change, so there would be no impact to the other layers. That's why networking is done as a stack, so that layers can be updated without affecting other layers.
