Transport -Layer Demultiplexing  What is meant by transport-layer demultiplexing?

选项
A.Receiving a transport-layer segment from the network layer, extracting the payload (data) and delivering the data to the correct socket.
B.Taking data from one socket, encapsulating a data chuck with header information (creating a transport layer segment) and passing this segment to the network layer.
C.Receiving a transport-layer segment from the network layer, extract the payload, find the destination IP address, and pass the segment and IP address back to the network layer.
D.Collect data from multiple sockets with the same destination IP, add destination port numbers, combine them into a transport-layer segment, and pass it to the network layer.

When approaching the concept of transport-layer demultiplexing, I first identify what the transport layer is responsible for: delivering data to the correct application endpoint (socket) on a host. Option 1 states: 'Receiving a transport-layer segment from the network layer, extracting the payload (data) and delivering the data to the correct socket.' This aligns with the core idea of demultiplexing: take the segment, interpret......Login to view full explanation

Which layer controls reliability of the communication?

Transport services and protocols    Select the correct option On the sending side, the transport layer receives the application-layer [ Select ] chunk datagram messages segments link-layer frame from a sending application process and converts it into a transport-layer [ Select ] datagrams link layer frame messages segments chunk . The transport layer then sends the [ Select ] message chunk datagram link-layer frame segment to the network layer at the sender’s end system, where it is encapsulated into a network-layer packet called a [ Select ] message segment link-layer frame datagram chunk , and forwarded to the destination. On the receiving side, the network layer extracts the transport-layer [ Select ] chunk datagram link-layer frame segments messages from the [ Select ] datagram chunk messages link-layer frame segments and delivers it to the transport layer.
