Resource management

Resource management is used to manage system assets and configurations. It maintains various resources and their properties. This includes physical resources, such as devices, servers, and Internet of Things (IoT) devices. It also includes logical resources, such as IP addresses and business traces.

Device

A device is typically an IP network communication device, such as a switch, router, or firewall. Depending on the scenario, this term can also refer to wireless network devices that require management and operations and maintenance (O&M), such as Access Points (APs) and Access Controllers (ACs).

Circuit (Link)

Links within a management domain can be single-ended or double-ended. Service types include internal services and connections to external services, such as leased lines.

Security domain

A security domain is a basic unit for managing resources, such as devices. It provides network isolation. Different security domains cannot communicate with each other. Agents within a security domain can operate in cluster mode or standalone mode.

Security domain codes usually follow a `service-location-role` pattern. For example, an IT department in a specific location responsible for education services could be defined as `EDU-LOC-IT`. You can also define your own naming rules. The code can only contain uppercase letters, numbers, underscores (_), and hyphens (-).

Configuration management

Configuration management involves collecting and maintaining the configuration status of network devices, service servers, and IoT resources. This includes managing hardware configurations, status data, backups of network element configuration files, and inspections.

Change center

The change center is a management hub for service provisioning scenarios. It acts as a network change orchestration engine that uses automation templates for atomic operations. All tasks, including service provisioning, routine maintenance, and automatic fault recovery, can be executed as tickets based on a defined plan. It supports any combination of manual and automated steps to control the ticket workflow and execution.

Automation template

An automation template automates the deployment of service configurations. This includes the execution of both user-defined logic and device-specific logic.

Service provisioning

Service provisioning refers to tasks such as creating, modifying, and decommissioning network services. It broadly covers any changes to network configurations and devices.

Circuit group (Link group)

A collection of circuits or links.

Change ticket

An executable ticket generated from a change plan and business data.

Change plan

A change plan is used by the change center. Users create a change plan by arranging the execution order and dependencies of template steps based on specific scenarios and O&M experience. The result is a standardized, reusable workflow.

Performance data

Performance data reflects the operational status of a network device. This data is often high-frequency and changes dynamically. Examples include latency and port packet errors.

Metric

A metric is a basic configuration item for device monitoring and data collection. It contains information such as the collection method (for example, PING or SNMP), collection interval, data items, and alert rule configurations.

Alert

An alert is a message issued by a resource, such as a network device, during its operation. Alerts are typically collected using active or passive methods.

Fault management

Fault management is the process of discovering, analyzing, and locating network faults. It involves a series of stream processing procedures, including collecting and storing alert information, matching rules, performing association analysis, and purging alerts.

Netconf

The Network Configuration Protocol (Netconf) is often used for configuring network services. It uses a structured, descriptive language to quickly deploy configurations to network devices.

gRPC

gRPC is a high-performance, open-source, and universal Remote Procedure Call (RPC) framework. For device management and monitoring, it provides near real-time configuration and data collection through dial-in and dial-out methods.

SNMP

Simple Network Management Protocol (SNMP) is a standard protocol widely used in TCP/IP networks for network management. It provides a way to collect operational status data from network devices at high frequencies.

OID

An Object Identifier (OID) is a sequence of numeric nodes that uniquely identifies a metric in an SNMP tree.
