这篇文章是以设计和组建一个企业网络为例子讲述了企业网络工程设计的基本方

This article takes the design and construction of an enterprise network as an example to describe the basic method and specific implementation process of enterprise network engineering design. Its main content includes network topology design, selected device types, IP address division, virtual local area network (VLAN) allocation, etc., adopts a variety of memorizations, among which the most critical are: network three-layer structure design, virtual local area network trunk protocol (VTP), port address translation (PAT), load balancing and redundant backup. Design through the application of many network technologies to form an expandable, redundant, and high-speed network, and at the same time can realize many service applications such as voice and image.

This article is based on the design and formation of an enterprise network as an example of the basic methods and specific implementation process of enterprise network engineering, its main contents include the topology design of the network, the choice of equipment type, IP address division, virtual local area network (VLAN) distribution, etc. , using a variety of remembers, the most critical of which is: network three-tier structure design, virtual LAN trunk protocol (VTP), port address conversion (PAT), load balancing and redundant backup. Designed through the application of many network technologies, so as to form a scalable, redundant, and high-speed network, and at the same time can achieve voice, image and many other service applications.

This paper describes the design process of VLAN (virtual network) and its implementation, including the design and implementation of virtual LAN This paper introduces the main road protocol (VTP), port address translation (PAT), load balancing and redundant backup. Through the application of many network technologies, the design forms a scalable, redundant and high-speed network, and can realize many service applications such as voice, image and so on.
