Transport layer error control is a redundant necessary. dd answered Sep 28, 2016 dd comment Share Follow See 1 comment See all 1 1 comment reply Sushant Gokhale commented Sep 29, 2016 reply Follow Share @Debashish. I think end-to-end delivery guarantee for transport layer is only applicable for TCP protocol. But there may be other protocols as well like UDP which dont perform error recovery. So, I think DLL is only the option. 0 votes 0 votes Please log in or register to add a comment.
