课程名称：对等协议与局域网 课程概述：本课程讨论对等协议和局域网。课程的第一部分重点解答对等协议如何在不可靠的传输线路或网络上提供可靠的数据传输服务。我们将重点分析几种介质访问控制协议及其性能。第二部分探讨介质访问控制协议如何协调通信通道的访问，以确保信息从来源有效传递到同一广播局域网中的目的地。此外，我们还讨论了局域网和无线局域网的相关内容。 课程大纲： 1. **部分一：对等协议** - 本模块研究对等协议及服务模型，重点讨论提供可靠数据传输服务的三种自动重传请求(ARQ)协议。 2. **部分二：可靠服务与数据链路控制** - 本模块介绍TCP协议，使用ARQ技术在无连接的数据包网络中提供可靠的流服务和端到端流量控制。同时还探讨了用于识别数字位流中信息帧边界的两种帧封装技术，以及两种广泛使用的数据链路控制标准。 3. **部分三：介质访问控制** - 本模块讨论了介质访问控制(MAC)的必要性，介绍了代表性的随机访问和调度MAC协议，包括形成以太网LAN标准基础的载波侦听多路访问碰撞检测(CSMA-CS)协议，并展示了延迟带宽积对协议性能的影响。 4. **部分四：局域网** - 本模块讨论局域网中使用的帧结构，并介绍几种重要的局域网标准，包括IEEE 802.3以太网和IEEE 802.11无线局域网。同时描述与每个局域网标准相关的MAC协议。 5. **部分五：课程项目 - 对等协议与局域网** - 该部分为综合性同行评审评估。 通过本课程，学员将深入了解对等协议和局域网的基础及其在现实世界中的应用。
Part: 1
Title:Peer-to-Peer Protocols
Description: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.
Part: 2
Title:Reliable Services and Data Link Controls
Description: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.
Part: 3
Title:Medium access control
Description: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.
Part: 4
Title:Local Area Networks
Description:This module discusses the structure of the frames used in LANs, and introduces several important LAN standards, including the IEEE 802.3 Ethernet LAN and IEEE 802.11 wireless LAN. Furthermore, the MAC protocols associated with each LAN standard are also described.
Part: 5
Title:course project - Peer-to-Peer Protocols and Local Area Networks
Description:This is a comprehensive peer review assessment
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.
