Computer Networking: Network Layer
In this free online course, learn about computer networking in the network layer of the TCP/IP protocol stack.
Description
In this free online course, you are introduced to the world of computer networking particularly focusing on the network layer. You will explore the broad objective of the network layer, as well as the importance of subnetting and supernetting in this layer and the benefits of using software defined networks. Demonstrations, problems, examples, and assessment questions in this instructor-led video-based course, are designed to provide you with a comprehensive foundation, which will enable you to take serious steps into understanding this section of the protocol stack.
The course begins by introducing you to the objectives and shortcomings of the network layer in computer networking. Then, the concept of IP addressing in the network is discussed to help you understand the importance of identifying the address which is identifying a network as well as a host inside that network. You will explore the variable-length subnet mask which makes it possible to solve some IP allocation problems that cannot be solved with the fixed-length subnet mask.
The course includes topics on autonomous systems, LAN, CIDR, network address translation, IPv6 Addressing, IP routers, router architecture, SDN architecture, OpenFlow, and more. This course will be of interest to computer engineering students, networking and programming professionals, or those looking to enhance their career prospects in the computer networking industry.
