As a leading global provider of communication technology solutions, Huawei has rich experience and leading technology in the field of network equipment. Its router product line is widely used in various network environments, providing users with efficient and secure network connections. Among them, the BNG (Broadband Network Gateway) function of Huawei routers and the related licenses are important components in the field of broadband access.
What’s BNG function
BNG function is a key feature provided by Huawei routers, playing a crucial role in broadband access networks. BNG is mainly used to connect broadband users to service provider networks and provide various services such as access control, authentication, authorization, billing, and traffic management. On Huawei routers, BNG function includes many key features, making it an ideal choice for supporting large-scale user access.
Below are some aspects of BNG function that may be covered on Huawei routers:
- Access Control: Huawei router’s BNG function can control user access, including authentication of user identities, execution of access policies, and more.
- User Authentication and Authorization: BNG function can authenticate users and authorize them based on their identities and permissions to ensure that only authorized users can access the network.
- Traffic Management: Huawei router’s BNG function can manage and control user network traffic, including bandwidth limitation, traffic policy execution, implementation of Quality of Service (QoS), and more.
- Address Allocation: BNG function can also be responsible for assigning IP addresses to accessing users, enabling them to communicate with the Internet.
- Reporting and Monitoring: Huawei router’s BNG function typically provides reporting and monitoring capabilities, allowing administrators to monitor network performance in real-time and generate reports for analysis and troubleshooting.
BNG function related license
For Huawei router’s BNG function, users typically need corresponding licenses to activate and use it. The BNG license is a software license that, when activated on the router, enables the BNG function to run on the router. Huawei provides a variety of BNG licenses with different specifications and capacities according to user needs and network scale, allowing users to choose the appropriate license based on their actual requirements.
Using the NE8000 M8 router as an example, available BNG licenses for the NE8000 M8 include the N1-NetEngine 8000 M8 Series BNG Function License and the N1-NetEngine 8000 M8 Subscribers Quantity(1k Subscribers). It is evident that the former is a functional license, controlling the router’s function toggle, while the latter is a resource-based license that can control the number of access users.
What is the difference between BNG and BRAS function?
BNG (Broadband Network Gateway) function and BRAS (Broadband Remote Access Server) function have similarities in some aspects, but they are actually two different network devices with different positioning and functions.
Here are the main differences between BNG function and BRAS function:
- BNG (Broadband Network Gateway):
BNG is a more comprehensive and advanced device, typically located at the core of broadband access networks, responsible for managing the access of a large number of users, handling user data traffic, and providing more network control and management functions.
BNG is commonly used to handle various types of broadband access, such as ADSL, fiber optics, Ethernet, etc., as well as different types of users, such as home users and enterprise users.
- BRAS (Broadband Remote Access Server):
BRAS is a device used for remote broadband access, typically located at the center of the service provider’s network, used to handle the connection of remote users accessing the network via dial-up, DSL, ADSL, fiber optics, etc.
The main functions of BRAS include access control, user authentication, traffic management, tunnel establishment, routing, and forwarding.
Although BNG and BRAS may provide similar functions in some cases, such as user access control and traffic management, they differ in terms of positioning, deployment scenarios, and functions.
