The ever expanding network and increasing network devices present a significant challenge in managing networks effectively and providing high-quality network services. There are many network management and O&M methods, of which this course describes some of the most common.

In the 1980s, the Internet Engineering Task Force (IETF) released RFC 791 – Internet Protocol, which marks the standardization of IPv4. In the following decades, IPv4 has become one of the most popular protocols. Numerous people have developed various applications based on IPv4 and made various supplements and enhancements to IPv4, enabling the Internet to flourish. However, with the expansion of the Internet and the development of new technologies such as 5G and Internet of Things (IoT), IPv4 faces more and more challenges. It is imperative to replace IPv4 with IPv6. This course describes the reasons for IPv4-to-IPv6 transition and basic IPv6 knowledge.

The open ecosystem of the computing industry brings booming development of multiple fields, such as Commercial Off-the-Shelf (COTS), operating system, virtualization, middleware, cloud computing, and software applications. The network industry is also seeking transformation and development. Software. Defined Networking (SDN) and Network Functions Virtualization (NFV) are mainly used. This course aims to help engineers understand the development of SDN and NFV and introduce Huawei SDN and NFV solutions.

New protocols, technologies, and delivery and O&M modes are emerging in the network engineering field. Conventional networks face challenges from new connection requirements, such as requirements for cloud computing and artificial intelligence (AI). Enterprises are also pursuing service agility, flexibility, and elasticity. Against this backdrop, network automation becomes increasingly important. Network programmability and automation is to simplify network configuration, management, monitoring, and operations for engineers and improve deployment and O&M efficiency. This course is to help network engineers understand Python programming and implement network automation.

A broad range of places, such as campuses, office spaces, and shopping malls, are covered by networks. You can access internal resources of your school, access internal printers of your company to print documents, or access the Internet to browse news through the networks. These networks belong to campus networks and are generally constructed by enterprises or organizations. Campus networks not only improve the operational efficiency of enterprises, but also provide network access services for external users.This chapter describes the basic architecture of a campus network and details how to build a campus network.

Sex education, also called sexuality education or sex and relationships education. It's the process of acquiring information and forming attitudes and beliefs about sex, sexual identity, relationships and intimacy. It is also about developing young people's skills so that they make informed choices about their behavior, and feel confident and competent about acting on these choices. It is widely accepted that young people have a right to sex education, partly because it is a means by which they are helped to protect themselves against abuse, exploitation, unintended pregnancies, sexually transmitted diseases and HIV/AIDS.

Immune system is a system of biological structures and processes within an organism that protects against diseases by identifying and killing pathogens and tumor cells. The immune system is made up of organs that are involved in fighting invasion by foreign bodies.
