Carrier-class Platform
The hardware platform provides a large data throughput, and the software platform seamlessly integrates the wireless telecommunications technologies and data communications technologies.
The hardware platform of the UGW9811 is Huawei Universal Switching Router (USR). The USR is a carrier-class network switching device that conforms to the industry standards. The software of the UGW9811 is developed based on Huawei Versatile Routing Platform (VRP) and integrates the routing technology of the VRP, IP quality of service (QoS) technology, virtual private network (VPN) technology, and security technology in data communications. In addition, the software provides enhanced functions related to applications in wireless telecommunication.
The UGW9811 provides a flexible solution to wireless data communications for network carriers because the hardware platform of the USR provides high reliability and large data throughput and the software platform seamlessly integrates the wireless telecommunications technologies and data communications technologies.
High Reliability
In order to ensure the availability of the UGW9811, reliability of hardware, software, and networking are all focal points when the UGW9811 is designed.
- Hardware reliability
The UGW9811 adopts the industry-leading network processors. The primary boards are hot-swappable and provide the hot backup function. The UGW9811 uses a dual-power supply system and has over-voltage and over-current protection.
- Software reliability
The UGW9811 provides diverse features to ensure software reliability, such as overload control, traffic control, resource check, automatic fault detection, charging data record (CDR) cache, and hot patching.
- Networking reliability
The UGW9811 provides route backup and route load-sharing modes and the Eth-trunk interface function to prevent adverse impacts of single-node or single-interface failures and ensure high network reliability.
High Security
In addition to reliability, carriers and subscribers are also concerned with security. The UGW9811 adopts the following measures to safeguard their benefits:
- Verification of operator identities
- Two authentication modes: Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP)
- Packet filtering and access control list (ACL) mechanism for filtering packets based on preset conditions
- SGi interface redirection to prevent packet attacks between UEs on the same UGW9811
- IPSec for providing IP packets with high-quality, interoperable, and cryptology-based security
