Introduction

1. Background and significance of standard formulation

This standard is edited by the Ministry of Housing and Urban-Rural Development, and China Mobile Communications Group Design Institute Co., Ltd. is responsible for the interpretation of the technical content. This standard aims to guide the design of public Internet network projects to ensure advanced technology, economic rationality, safety, reliability and sustainable development.

2. Comparative Analysis of Standard Frameworks

Chapter Number Chapter Content Keywords
1 General Provisions Technical Requirements, Safety and Applicability
2 Terms and Codes IP Network, Network Node
3 Network Composition and Function Dual Stack Technology, Service Bearing

3. Analysis of Technology Evolution

With the development of Internet technology, the transition from IPv4 to IPv6 has become necessary. The application of dual-stack technology supports network nodes to process two protocols at the same time, ensuring a smooth transition. The introduction of SDN (Software Defined Network) and NFV (Network Function Virtualization) has improved the flexibility of network management.

4. Implementation Recommendations

4.1 Network Planning and Design

  • Ensure that the network hierarchy is reasonable and avoid redundancy and complexity.
  • Choose appropriate routing protocols (such as IS-IS or OSPF) to improve the efficiency of intra-domain communication.

4.2 Security and Management

  • Strengthen the security system and conduct penetration tests and vulnerability scans regularly.
  • Use the network management system to achieve centralized monitoring and configuration management of network devices.
