Sau khi học xong Bài giảng Mạng máy tính căn bản - Chương 9: TCP/IP protocol suite and IP addressing người học có thể giải thích lý do tại sao Internet đã được phát triển và làm thế nào TCP / IP phù hợp với thiết kế của Internet, mô tả các chức năng của mỗi lớp của giao thức TCP / IP mô hình,. | Chapter 9 TCP/IP PROTOCOL SUITE AND IP ADDRESSING Overview Internet based on the TCP/IP protocol suite. The design of TCP/IP is ideal for the decentralized and robust network that is the Internet. Many protocols used today were designed using the four-layer TCP/IP model. Phan Vĩnh Thuần It is useful to know both the TCP/IP and OSI networking models. Each model offers its own structure for explaining how a network works but there is much overlap between the two. Without an understanding of both, a system administrator may not have sufficient insight into why a network functions the way it does. Phan Vĩnh Thuần Any device on the Internet that wants to communicate with other Internet devices must have a unique identifier. The identifier is known as the IP address because routers use a layer three protocol, the IP protocol, to find the best route to that device. IPv4, the current version of IP, was designed before there was a large demand for addresses.

The identifier is known as the IP address because routers use a layer three protocol, the IP protocol, to find the best route to that device. IPv4, the current version of IP, was designed before there was a large demand for addresses. Phan Vĩnh Thuần Explosive growth of the Internet has threatened to deplete the supply of IP addresses. Subnetting, Network Address Translation (NAT) and private addressing are used to extend IP addressing without exhausting the supply. Another version of IP known as IPv6 improves on the current version providing a much larger address space, integrating or eliminating the methods used to work with the shortcomings of IPv4. Phan Vĩnh Thuần In addition to the physical MAC address, each computer needs a unique IP address, sometimes called logical address, to be part of the Internet. There are several methods of assigning an IP address to a device. Some devices always have a static address, while others have a temporary address assigned to them every time they connect to the network. When a dynamically assigned IP address is needed, the device can obtain it using several methods. Phan Vĩnh Thuần For efficient routing to occur between devices, other issues must be resolved. For example, duplicate IP .
