ICND1 2.0: The Transport Layer and Router Configuration

Data networks and the Internet provide seamless and reliable communication between people. Applications such as e-mail, web browsers, and instant messaging allow people to use computers and networks to send messages and find information. Data from applications is packaged, transported, and delivered to the appropriate server or application on the destination device. The processes that are described in the TCP/IP transport layer accept data from the application layer and prepare it for addressing at the Internet layer. The transport layer is responsible for the overall end-to-end transfer of application data. The transport layer also encompasses functions to enable multiple applications to communicate over the network at the same time on a single device. This layer can use error-processing mechanisms to ensure that all of the data is received reliably and in order by the correct application. For the Internet and internal networks to function correctly, data must be delivered reliably. You can ensure reliable delivery of data through development of an application and by using the services that are provided by the network protocol. In the TCP/IP and OSI models, the transport layer manages the process of reliable data delivery. The transport layer hides the details of any network-dependent information from the higher layers to provide transparent data transfer. TCP/IP UDP and TCP therefore operate between the network layer and the application layer. Learning how UDP and TCP function between the network layer and the transport layer provides a more complete understanding of how data is transmitted in a TCP/IP networking environment. This course describes the function of the transport layer and how UDP and TCP operate. Routing is the process that forwards data packets between networks or subnetworks, using a TCP/IP Internet layer device, that is, a router. The routing process uses network routing tables, protocols, and algorithms to determine the most efficient path for forwarding an IP packet. Routers gather routing information and update other routers about changes in the network. Routers greatly expand the scalability of networks by terminating Layer 2 collisions and broadcast domains. Understanding how routers function will help you to understand the broader topic of how networks are connected and how data is transmitted over networks. This course describes the operation of routing. After hardware installation, when a Cisco router is turned on, it goes through its startup procedure. Once the operating system is loaded, you can start configuring the router. This course concludes by describing basic configurations, how to configure interfaces, and how to use Cisco Discovery Protocol to discover connected neighboring devices.

Target Audience
Interconnecting Cisco Network Devices Part 1 is essential for students preparing for the CCNA Routing and Switching or CCENT certifications. Students pursuing the CCNA Routing and Switching certification should complete parts 1 & 2 of the ICND learning path. Students pursuing the CCENT certification need only attend part 1 of the ICND curriculum. Anyone wishing to obtain Cisco Certified Network Associate (CCNA) 100-101 certification that validates the knowledge and skills required to successfully install, operate, and troubleshoot small to medium size enterprise branch network. Network administrators, network engineers, network managers, network designers, and project managers. Familiarity of navigating PC operating systems, the Internet, and basic IP addressing knowledge skills recommended.
