Identify the role of the Network Layer, as it describes communication from one end device to another end device Examine the most common Network Layer protocol, Internet Protocol (IP), and its features for providing connectionless and best-effort service Understand the principles used to guide the division or grouping of devices into networks Understand the hierarchical addressing of devices and how this allows communication between networks Understand the fundamentals of routes, next hop addresses and packet forwarding to a destination network . | Chapter 5 - OSI Network Layer CCNA Exploration version CISCO Overview Identify the role of the Network Layer as it describes communication from one end device to another end device Examine the most common Network Layer protocol Internet Protocol IP and its features for providing connectionless and best-effort service Understand the principles used to guide the division or grouping of devices into networks Understand the hierarchical addressing of devices and how this allows communication between networks Understand the fundamentals of routes next hop addresses and packet forwarding to a destination network .Ao Học viện mạng Bách khoa - Website 2 Network Layer Protocols and Internet Protocol IP Our devices use the Transport layer to connect processes. Routers connected to each other And the Network layer enables devices to reach each other 4 Session Transport Network Data Link Physical Define the basic role of the Network Layer in data networks The protocols of the OSI model Network layer specify addressing and processes that enable Transport layer data to be packaged and transported. The Network layer encapsulation allows its contents to be passed to the destination within a network or on another network with minimum overhead. Học viện mạng Bách khoa - Website
