"Sliding window" - is it possible to add reliability to the protocol and avoid flow control?

Question

As part of a personal project, I am making an application layer protocol (encapsulated in UDP) that is reliable.

To implement reliability, I have to keep track of which packets I send and which packets are received at the other end of the receiver. This is done using a sliding window, and also supports flow control.

• Is there a way to implement reliability other than the standard window / stream deployment method.
• If not, someone will share their experience / concept / code and discuss it in this article.
• If so, have you implemented it or do you know any implementation of the concept.

Answer 1

After reading all these answers, studying other implementations, and reading some articles, I write / share what is most appropriate. First, let me talk about flow control, and later I will talk about reliability.

There are two types of flow control -

• Rate based - Packets Transfer is done on time.
• Window - a standard window, can be static or dynamic (sliding window).

Answer 7

You might want to watch SCTP - it is reliable and message-oriented.
