1. Analysis of IP network bandwidth management and application optimization requirements With the gradual development of the Internet, the number of online users and business traffic is constantly increasing. In addition to traditional data services, new network applications, such as network phones, online videos, and

by the application layer of the other system. For example, a PC program communicates with another computer, where one computer uses an extended 210 binary interchange (EBCDIC), and the other uses the U.S. Information Interchange Standard Code (ASCII) to represent the same characters. If necessary, the presentation layer enables conversion between multiple data formats by using a pass-through format. 7. Application layer: The OSI layer closest to the user. This layer provides

As we all know, in telephone communication, telephone users are identified by phone numbers. Similarly, in order to distinguish different computers in the network, you also need to specify a number for the computer, which is the "ip address ". 　　What is an IP address? The IP address is a 32bit address allocated to eac

So I am looking for some related information on the Internet. below is my understanding of the plug-in ., After March 1990s, with the development of computing machines and network technologies, manyData processing systems use open and release systems to build a

Vroip IP restrictions are set in many companies to prevent employees from doing work-related tasks during work hours. But it also limits employees to use the network for better work, so this is a dilemma. How to Implement the function of limiting thunder by using the IP address of the router. Currently, three computers in one LAN, two XP computers, one VISTA comp

Introduction to TCP/IP network protocols Some time ago I made a development, involving network programming, and the development process was quite smooth, but I always felt a bit confused after the task was completed. The main reason is that you are not familiar with network protocols and are not clear about some conce

After installing VMware, two NICs are added to the Network connection: VMware Network Adapter VMnet1 and VMware Network Adapter VMnet8. VMnet1 is the host Nic used to connect to the network in the host mode. VMnet8 is a NAT Nic used to connect to the network in NAT mode. Th

For wireless data networks, voice is a "killer application ". The high-performance Wi-Fi mesh network system is a killer IP wireless network. However, not all mesh networks are identical. As wireless mesh networks become increasingly popular-almost every day, people announce the newly deployed public and private networks. To add voice applications to business nee
