In this chapter, we've examined the data link layer - its services, the principles underlying its operation, and a number of important specific protocols that use these principles in implementing data link services We saw that the basic service of the data link layer is to move a network-layer datagram from one node (router or host) to an adjacent node We saw that all data link protocols operate by encapsulating a network-layer datagram within a link-layer frame before transmitting the frame over the "link" to the adjacent node Beyond this common framing function, however, we learned that different data link protocols can provide very different link access, delivery (reliability, error detection/correction), flow control, and transmission (eg, full-duplex versus half-duplex) services These differences are due in part to the wide variety of link types over which data link protocols must operate A simple point-topoint link has a single sender and receiver communicating over a single "wire" A multiple access link is shared among many senders and receivers; consequently the data link protocol for a multiple access channel has a protocol (its multiple access protocol) for coordinating link access In the cases of ATM, X25 and frame relay, we saw that the "link" connecting two adjacent nodes (eg, two IP routers that are adjacent in an IP sense - that they are next-hop IP routers towards some destination), may actually be a network in and of itself In one sense, the idea of a network being considered as a "link" should not seem odd A telephone "link" connecting a home modem/computer to a remote modem/router, for example, is actually a path through a sophisticated and complex telephone network Among the principles underlying data link communication, we examined error detection and correction techniques, multiple access protocols, link-layer addressing, and the construction of extended local area networks via hubs bridges, and switches In the case of error detection/correction, we examined how it is possible to add additional bits to a frame's header that are used to detect, and in some cases correct, bitflip errors that might occur when the frame is transmitted over the link We covered simple parity and checksumming schemes, as well as the more robust cyclic redundancy check We then moved on to the topic of multiple access protocols We identified and studied three broad approaches for coordinating access to a broadcast channel: channel partitioning approaches (TDM, FDM, CDMA), random access approaches (the ALOHA protocols, and CSMA protocols), and taking-turns approaches (polling and token passing) We saw that a consequence of having multiple nodes share a single broadcast channel was the need to provide node address at the data link level We learned that physical addresses were quite different from network-layer addresses, and that in the case of the Internet, a special protocol (ARP - the address resolution protocol) is used to translate between these two forms of addressing We then examined how nodes sharing a broadcast channel form a local area network (LAN), and how multiple LANs can be connected together to form larger LANs - all without the intervention of network-layer routing to interconnect these local nodes Finally, we covered a number of specific data link layer protocols in detail - Ethernet, the wireless IEEE 80211 protocol, and the Point-to-Point protocol, PPP As discussed in sections 59 and 510, ATM, X25, and frame relay can also be used to connect two
