Foreword

Appendix A and Appendix B of this standard are informative annexes.

This standard was proposed by the State Tobacco Monopoly Bureau.

This standard is under the jurisdiction of the Information Subcommittee of the National Tobacco Standardization Technical Committee (TC144/SC7).

This standard was drafted. National Tobacco Monopoly Bureau Tobacco Economic Information Center, Beijing Lianxin Yongyi Information Technology Co., Ltd.

Introduction

The tobacco industry has built a tobacco industry information and communication network covering the whole industry with the industry's ground communication backbone network as the core.

The Grass Monopoly Bureau (hereinafter referred to as the National Bureau) and its subordinate units have also basically built a local area network, and the ground network system base for interoperability in the industry.

This formation. The industry ground communication backbone network and the national bureau and provincial unit LAN constitute the bearer network for the multimedia business of the tobacco industry.

The multimedia communication service system of the tobacco industry includes video conferencing, IP telephony, and distance learning. Video conferencing business can Provide fast and convenient communication methods in the tobacco industry, while saving costs and saving time; IP telephony services can enable tobacco companies to High office efficiency and communication cost savings; distance learning system is mainly used for remote training and video resources remotely within the tobacco industry Play.

The tobacco industry multimedia communication service system follows the following principles in technical design.

(1) Practicality

The design of the entire business system fully reflects the practicality of the system, which requires both advanced technology and economically acceptable conditions.

The demand for multimedia applications in the tobacco industry, to avoid excessive investment in the technology environment.

(2) Security

The security of the multimedia communication service system should be guaranteed to prevent illegal attacks and access by illegal users.

(3) Reliability

Highly reliable network platforms, hardware platforms and software systems should be used to ensure the reliability of the entire system.

(4) Advanced

Designing multimedia communication service systems using advanced design ideas and IP technologies, and with existing or foreseeable future the equipment that can be used is compatible.

(5) Openness

The open, industry-standard multimedia communications service products should be used to simplify management, maintenance and upgrade functions. Network hardware the environment, communication environment, and software environment are independent of each other, and they are self-contained platforms, and mutual dependence should be minimized. Ensure new systems and new systems Interoperability with legacy systems.

(6) Scalability

Should have strong expansion capabilities to meet the needs of existing business and future business development.
