In this course, we deal with the general issues regarding packet switching networks. We discuss packet networks from two perspectives. One perspective involves external view of the network, and is concerned with services that the network provides to the transport layer that operates above it at the end systems. The second perspective is concerned with the internal operation of a network, including approaches directing information across the network, addressing and routing procedures, as well as congestion control inside the network.
This module introduces LAN bridges and data link layer switching, and then focuses on packet switching at the network layer. It discusses datagram, one basic packet switching approaches.

Shortest-Path Routing
Module 3•3 hours to complete
Module details
This module introduces the link state routing, examines the Dijkstra algorithm for shortest-path routing, and discusses the applications of the distance vector and link state routing in real Internet protocols.
This module discusses packet-level traffic management operating in a short time scale, continues with traffic management at the flow level operating in a medium time scale. Common approaches including scheduling, queuing, admission control, and congestion control are discussed.

When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. 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.
What will I get if I subscribe to this Specialization?
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.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
