If a communications session needed encryption or compression, which layer of the ISO/OSI Reference Model would perform this function?
Step by step
Solved in 2 steps
- Where would this function be executed in the ISO/OSI Reference Model if an encrypted or compressed communications session was needed during a communication session?If a communications session were to employ encryption or compression, which layer of the ISO/OSI Reference Model would perform this service?Examine the function of each of the seven OSI layers and the protocols that run on them.
- Which layer of the ISO/OSI Reference Model would be responsible for encryption or compression during a communication session?The term synchronization has many meanings in Computer Science. Within the networking field, the term is usually used to describe making asynchronous communication synchronous (A coordination of activities; running at the same rate) We see synchronization occurring in different layers, but we are mostly concerned with the physical layer and the data link layer (L1 and L2). a) In what ways is synchronization in these two layers similar? b) In what ways is synchronization in these two layers dissimilar?Consider a TCP segment originating on a host running a Google Chrome Browser destined for the TU Dublin Webserver: (1) Separately identify how the port numbers are assigned for the client and server applications and, identify the range from which these port numbers are allocated. (ii) Identify the byte order used to represent these addresses within the segment header. (iii) If a port number contained in the segment header is passed to the Application layer, identify the function used to convert it to the correct byte order within the application.
- Which tier of the ISO/OSI Reference Model would execute this function if a communications session required encryption or compression?How do protocols transfer across OSI layers?A 4480-octet datagram is to be transmitted and needs to be fragmented because it will pass through an Ethernet with a maximum payload of 1500 octets. Show the Total Length, More Flag, and Fragment Offset values in each of the resulting fragments.
