When receiving, the network layer: • Removes the network header from the NPDU to form the TPDU. • Verifies destination address and sequence number. • Reassembles the TPDU, if necessary. • Passes it to the transport layer. Peer-to-peer communication is required to initiate, maintain and terminate the network level connection. These functions are performed by the network header. 6 Data Link Layer The data link layer transfers data frames over a single communication link without intermediate nodes.
Notes any specific markers. 3 Open Systems Interconnection Model • 35 Passes the PPDU to the presentation layer. Peer-to-peer communication is required to check authorizations and agree upon line discipline and the use of markers. They are functions included in the session header. 4 Transport Layer The transport layer is the highest layer in the stack to be concerned with communication protocols. It ensures the integrity of end-to-end communication independent of the number of networks involved, and their performance.
