What is wnd to end principle in system design?

[networkloser]

The kurose ross book says udp provides error detection is an example of end to end principle in system design. I want to further research humanly on this. Pls 🙏 guide

End to end means being able to track things in a system. In the case of TCP communications, it's confirmation messages. For UDP, as it does not have confirmation messages, then being able to detect breaks in the communication path will enable an administrator to determine if messages are being delivered or not.
