Huawei CloudEdge is a new-generation mobile broadband (MBB) solution developed based on Network Functions Virtualization (NFV), service oriented architecture (SOA), and cloud architecture. The CloudEPC (evolved packet core), CloudMSE (multimedia service engine), and CloudUIC (unified intelligence controller) collectively form the CloudEdge solution, which involves the convergence of data from multiple RAT modes.
The CloudEdge solution optimizes and enhances the supporting application software to provide cloud-based advantages, such as automatic deployment and elastic scaling, to meet carrier-grade requirements of availability, performance, and O&M. This solution possesses the prerequisite evolution capacity to be readily applied towards future 5G networking.
The CloudEdge architecture features three "D"s.
Disaggregation: An evolution of the current layer-based cloudification of network services will enable further decoupling of the control plane from the user plane. The network can then benefit from increased simplicity, while allowing for programmable network capabilities.
Dynamic: Network deployment will no longer be static. Service-oriented dynamic deployment will manifest as the mainstream practice, achieving application-driven E2E network slicing.
Diversity: Business of carriers will be expanded from telecommunications to OTT, IoT, enterprise, and other additional diversified fields.
Software performance optimization and hardware acceleration technologies are horizontally applied on the same layer, vertically across layers, and between virtual machines (VMs). The carrier-grade performance is therefore guaranteed
Infrastructure independence ensures long-term evolution. Integration and pre-integration with vertical industries, automatic tools, and flow operation reduce the TTM by 80%
Intelligent E2E O&M is crucial to enabling network automation. Key features including cross-layer fault locating and hitless upgrade, as well as a predefined set of O&M tools, help facilitate intelligent O&M
Multi-level HA ensures reliability of 99.999%. Active/standby redundancy and stateless N+M mechanism at the application layer prevents session interruption. The cross-data-center deployment ensures remote disaster recovery and efficient allocation of resources
