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.

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.

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.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
