Web17 apr. 2015 · The network layer adds its own header to form a network layer packet (e.g., an IP packet). In Fig. 4-45(b), we see the IP packet shaded in gray. Then the packet goes to the data link layer, which adds its own header and checksum (CRC) and gives the re- sulting frame to the physical layer for transmission, for example, over a LAN. WebThe data-link layer is the software closest to the hardware (physical layer). Thus, it includes, among other functions, any software needed to control the hardware. Bridging also occurs at this layer to allow networks interconnected with different physical layer protocols (e.g., Ethernet LAN and an 802.11 LAN) to interconnect. Like physical ...
