CM

The consumption model (CM) is a new hardware sales model that enables customers to purchase large-capacity and high-density boards in installments to achieve the desired hardware capacity while reducing initial costs. In the future, to meet service development requirements, customers can flexibly purchase hardware licenses for capacity expansion.

Background

This flexible sales model also enables customers to purchase hardware in installments, further lowering the initial purchase threshold. Customers can purchase boards step by step based on the required capacity rather than having to pay for all the required boards at a time. In addition, customers can invest in network construction flexibly based on income to quickly respond to market requirements with minimum initial costs.

Basic Concepts

The CM consists of the following elements:

(Mandatory) Hardware boards that support the CM.
(Mandatory) Hardware right to use (RTU) licenses: After a license is loaded to an interface, the interface has the corresponding bandwidth.
(Optional) Service license (Function): After a license is enabled on an interface, the interface supports L3VPN.

Comparison Between the CM Model and Conventional Model

Table 1 compares the CM and the conventional mode. The CM enables on-demand flexible purchase.

**Table 1** Comparison between the CM model and conventional model
Category	Mandatory or Optional	CM	Conventional Model
Service License (Function)	Optional	To be loaded on a working interface to enable the interface to have an enhanced function.	Functional license that enables the entire board to have the corresponding function after the license is loaded.
RTU License	Mandatory	To be loaded on an interface to enable the interface to work and support the IP/MPLS/L2VPN function.	Conventional board. Entire board capacity. All interfaces are available. The board supports functions such as IP, MPLS, L2VPN, and L3VPN.
Board	Mandatory	Board that supports the CM. Some interfaces are not available.
Device	Mandatory	Infrastructure, which is the same for the CM and the conventional model.

Application Procedure

Install the boards.
Obtain the ESN from the device and apply to Huawei for the matching license authorization file.
Load and activate the license authorization file.
Activate the hardware RTU and service license (Function).
Configure the corresponding service.

Benefits

The CM offers the following benefits to customers:

Reduced initial investment: Customers break even more quickly.
Improved slot utilization: The capability of a single slot is improved 2–4 fold, saving a large number of slots and chassis.
Reduced OPEX: Customers can provision services by remotely loading licenses. Therefore, customers do not need to install boards on site to implement capacity expansion.
