10 Questions
Link layer protocol defines the format of the packets exchanged between nodes at end of the link
Framing
MAC layer adds a header and trailer to the packet
Data encapsulation
Link layer services define how to access channel for shared medium
Link access
MAC layer adds a physical address (MAC address) that enables a frame to be delivered to a destination node
Addressing
Frame assembly before transmission and frame disassembly upon reception of a frame
Data encapsulation
Link layer services encapsulates datagram into frame, adding header, trailer defines how to access channel for shared medium Defines the “MAC” addresses to identify source, dest different from IP address.
Framing
MAC layer provides three primary functions: ▪ Frame delimiting – Identifies a group of bits that comprise a frame, synchronization ▪ Addressing –adds a physical address (MAC address) that enables a frame to be delivered to a destination node. ▪ ___________
