關於此課程：In this course, we discuss peer-to-peer protocols and local area networks. Part one in this course is to answer the question of how does a peer-to-peer protocol deliver reliable data transfer service across unreliable transmission lines or networks. We focus on several medium access control protocols and their performance analysis. In the second part, we discuss how medium access control protocols coordinate the access to the communication channel so that information gets through from a source to a destination in the same broadcast local area network. We further discuss local area network and wireless LAN.

Peer-to-Peer Protocols
This module examines peer-to-peer protocols and service models. Importantly, it examines three automatic repeat request (ARQ) protocols that provide reliable data transfer service.

Reliable Services and Data Link Controls
This module introduces TCP that uses ARQ techniques to provide reliable stream service and flow control end-to-end across connectionless packet network. It also examines two framing techniques that are used to identify the boundaries of frames of information within a digital bit stream, and discusses two data link control standards in widespread use.

Medium access control
This module discusses the need for medium access control (MAC), and introduces representative random access and scheduling MAC protocols - including the carrier-sense multiple access with collision detection CSMA-CS protocol which forms the basis for the Ethernet LAN standard. It also shows the impact of delay-bandwidth product on protocol performance.
