Link Layer Error Detection and Correction Addressing ARP Take-Home Points Link Layer link layer is responsible for transferring a frame of data between two nodes over a single link many different types of links wired and wireless point-to-point vs shared medium each link can potentially run a different protocol (Ethernet, 802.11), may provide different services (reliability, multicast) Link Layer Daniel Zappala 4/17

Link Layer Error Detection and Correction Addressing ARP Take-Home Points Link Layer Services framing, data transmission encapsulate data into a frame, adding header and/or trailer may use link-layer addressing, likely different from IP addresses negotiate channel access on shared medium reliable delivery seldom used on links with low error rates (fiber) wireless links have high error rates, may include retransmission why implement this at both link layer and transport layer?
