assume that the link layer uses the flag bytes with byte stuffing approach for framing, with the following details: The beginning of a data frame is indicated by the special flag bytes: DLESTX The end of a data frame is indicated by the special flag bytes: DLEETX The special escape bytes DLE are used for escaping accidental occurrences of either the flag bytes or the escape bytes within the data. For simplicity, assume that no other header/trailer information is added to the data.   1. The following byte stream represents data that needs to be framed by the link layer on the sender’s side. Derive the resultant byte stream by adding necessary flag bytes and performing byte stuffing. PARSDLEETXZKPUM   I have this answer but it is wrong    DLESTXPARDLEETXZKPUMDLEETX

Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.
