Network operation and maintenance refers to Internet operation and maintenance, which usually belongs to the technical department, and is the same as R&D, testing, and system management, which are the four major departments of technical support for Internet products.

Network O&M refers to the production organization and management activities taken to ensure the normal and effective operation of telecom networks and services, referred to as O&M management or OAM, which is responsible for maintaining and ensuring the high availability of the entire service, while continuously optimizing the system architecture and improving deployment efficiency.

Network operation and maintenance job responsibilities, maintenance and monitoring of the best service, responsible for the research, inquiry, procurement, installation, upgrade, storage, maintenance and other work of the system software and hardware, database maintenance, performance tuning, data backup and recovery, data import and export, for the system and network abnormal phenomena network management should be analyzed in a timely manner, processing, and take countermeasures.

What to learn from network operations

For the common faults of the network, for example, the crash and restart of the machine, it is nothing more than the CPU temperature is too high, the machine has a virus, the operating system has a problem or the power supply, these faults are more obvious, and it is easy to judge and solve, change the battery or reinstall the system, however, many faults are hidden, this fault is so, let's take a look at its analysis, network maintenance about the fault analysis of the network speed slowdown.

Hardware basics, understand the principle, CPU, memory, disk, network card, etc., such as CPU cache, instruction set, architecture, pipeline, protection mode, disk seek principle, common performance indicators of various levels of RAID, SSD, SAS, SATA, etc., such as IOPS, bandwidth, throughput, etc., operating system, need to be familiar, it is best to be proficient. Process scheduling, memory management, file system, peripheral management, etc., should be proficient in using related tools.
