1、 Introduction to IP MAN:

Broadband IP man is the service extension and regional coverage of data backbone network and long-distance telephone network in the metropolitan area. It takes broadband transmission as the open platform, realizes the access of voice, data, image, multimedia, IP, various value-added services and intelligent services through various gateways, and is a local integrated service network that communicates with the long-distance and PSTN of various operators. Broadband IP man is a broadband multimedia communication network built according to the needs of business development and competition within the city (possibly including the counties and districts under its jurisdiction). It is a broadband backbone network. For example, China Telecom's IP backbone network is an extension within the city, and as a part of the local public information service platform, it is responsible for carrying various multimedia services, providing users with various access methods, and meeting the needs of government departments, enterprises and institutions and individual users for various multimedia services based on IP. Therefore, broadband IP man must be a manageable and scalable telecom operation network.

2、 Business functions:

1. Good scalability and flexibility, suitable for large-scale implementation;

2. User and network security are basically equivalent to that of PVC on the second layer;

3. Support multiple business levels and provide certain service quality;

4. Support Ethernet, frame relay, DDN, ATM and other access modes;

5. Diversified applications can quickly implement IP value-added services;

6. Simple user configuration, convenient management, simple and fast implementation, and economical

3、 Characteristics of IP MAN:

1. High transmission bandwidth (providing high-speed access from 100MB to the building and 10MB to the desktop);

2. Provide various multimedia services (video on demand, distance education, e-commerce, holding video conferences, making video calls, etc.);

3. Free access to the Internet for 24 hours without time limit; Convenient maintenance and simple structure;

4. High reliability, safety and strong expansibility.
