CEM-Huawei converged power communications network illuminates Asia's entertainment capital Huawei paid
The network had been in use since 2008 and the technology could not satisfy the network reliability requirements of new services and changing industry standards. In addition, the existing network was unable to support the operation of additional services due to inadequate network isolation. This indicated there was a lack of effective segmentation and protection between services.
Huawei’s carrier network solution calculates different services, as well as data transmission and bandwidth requirements, and then incorporates the innovative ‘zone-specific, multi-level, and layered’ concept, to use optical transmission equipment such as Wavelength-Division Multiplexing , Optical Transport Networking , and Hybrid Multi-Service Transport Platform in network construction. The solution also considers the structure, voltage levels, and regional interconnection of the power grid.
In the solution, built-in PCM boards allow for the creation of ‘all-in-one’ devices that enable direct network access for traditional low-speed services and Foreign Exchange Office interface telephones). The devices also reduce equipment stacking and service cascade conversion, simplify the network, and improve network reliability.
CEM’s different systems in the power generation zone of the network are logically separated, with cross-regional access provided through the USG series firewall, which provides fine-grained application layer protection and service acceleration. Policies can be set by the administrator. The Next-Generation Firewall provides simple, unified network security for CEM that includes virus, spam, and Distributed Denial of Service attack protection, as well as malicious traffic detection.
