What layer of the OSI model do the protocols Ethernet PPP and Frame Relay operate on? The transport layer controls the reliability of a given link through flow control, segmentation and desegmentation, and error control. Layer 4 of the OSI Model: Transport Layer provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers. This ensures that the destination application has the data in the exact form the sender intended. This sequence number allows the Transport layer functions on the destination host to reassemble segments in the order in which they were transmitted. In TCP, each segment header contains a sequence number. Which information provides for the reassembly of the segments in the correct order at the destination? Thus by specifying this address, the transport layer makes sure that the message is delivered to the correct process. Service Point Addressing: In order to deliver the message to the correct process, the transport layer header includes a type of address called service point address or port address. Which OSI layer header contains the address? To transmit the packets the sender uses network address and datalink address. Which OSI layer header contains the address of a destination host that is on another network? Explanation: Only network address contains this information. Layer 3 of the OSI Model: Network Layer provides the functional and procedural means of transferring variable length data sequences from a source host on one network to a destination host on a different network, while maintaining the quality of service requested by the transport layer (in contrast to the data link … Which OSI layer header contains the address of destination host that is on another network? Which network devices function only at Layer 1 of the OSI model? Which OSI layer provides the address of a destination host that is on another network group of answer choices?
