As shown in Figure 1, licenses can be classified as follows:

In terms of commercial use, licenses are classified as either commercial or non-commercial licenses.
Non-commercial licenses are mainly used in exhibition, R&D, and in non-R&D labs. Commercial licenses are generally used at commercial sites. In addition to commercial projects, commercial licenses can also be used in beta tests, testing, and certification.
Based on the validity period, licenses can be classified as fixed-term or permanent licenses.
After a fixed-term license is activated, it can be used within the fixed period. After the fixed-term license expires, it needs to be activated again. Non-commercial licenses generally have a fixed validity period. A permanent license can be used permanently after being activated. Currently, licenses that are purchased for commercial projects are all permanent licenses.
In terms of the license management mode, licenses are classified as cloud-based licenses and non-cloud-based licenses.
In cloud-based license mode, you can activate and manage a license resource pool on the license management platform to dynamically allocate and reclaim license control items among multiple devices registered in the resource pool, implementing license resource sharing and dynamic adjustment among multiple devices. The non-cloud-based license mode is the traditional standalone license mode. The license resources of each device are static and fixed. To adjust the allocation of license resources among multiple devices, you need to split the license and activate it again.

Based on the objects activated by operators, licenses are classified as GTL, hardware Right to Use (RTU), service license, or trial license, as shown in Table 1.

**Table 1** Licenses classified based on the objects activated by operators
License	Description
GTL	The license file is preinstalled on a device before delivery or can be downloaded from the ESDP website based on the project contract and device ESN. Commercial licenses and non-commercial licenses (excluding trial licenses) are physically presented as license files.
Hardware RTU	Hardware RTUs control the valid ports of boards or devices that are sold in consumption model (CM). Ports of boards or devices that are sold in consumption model (CM) are not available until hardware RTUs are activated.
Service license	A software license control item that controls one or more services. There are two types of service licenses: Function control service license: With Item type being Function, this type of license takes effect on the entire device. Resource control service license: With Item type being Resource, this type of license takes effect on the board in a specified slot or on a specified port.
Trial license	License control item that supports trial use. A trial license can be enabled twice for each R version. Each time a trial license is enabled, it can be used for a maximum of 90 days. When the trial period ends, the controlled features become invalid immediately or after the device is restarted. These controlled features can still be used only if a commercial license is purchased.
