Huawei SDSec USG9500 Series Terabit-Level Next-Generation Firewall
The USG9500 series comprises the USG9520, USG9560, and USG9580, and provides industry-leading security capabilities and scalability. The firewall throughput of the series is up to 1.92 Tbps.
By using dedicated multi-core chips and a distributed hardware platform, the USG9500 provides industry-leading service processing and expansion capabilities. Moreover, all key components are redundant to ensure service continuity on high-speed networks, providing a level of availability that is normally seen in core routers. The distributed technology uses line-rate intelligent traffic distribution for data forwarding. All data flows are equally distributed to service processing units (SPUs) to prevent performance bottlenecks. Therefore, the service processing capability increases linearly with service modules, supporting the long-term development of customer networks.
The USG9500 provides multiple types of I/O interface modules (LPUs) for external connections and data transmissions. Line processing units (LPUs) and SPUs have the same interface slots and can be mixed and matched as needed. The SPUs of the USG9500 process all services. The motherboard of each SPU can hold expansion cards that house multi-core CPUs, which together with the software modules allow the SPUs to process all services on the USG9500. To ensure service continuity, the USG9500 provides SPU redundancy and a heartbeat detection mechanism between the SPU and LPU If one SPU fails, all functions are switched to other SPUs without interrupting service transmission. In addition, the USG9500 provides GE, 10GE, 40GE and 100GE interfaces and supports cross-board port bundling to improve throughput and port density.
