The Network Cloud Engine-IP, a core component of the Huawei IP WAN solution, enables cloud-based WAN solutions to maximize the value of networks. The Network Cloud Engine-IP has strong and flexible management capabilities that allow the rapid deployment and provisioning of VPN services on WANs. It can automate the monitoring, planning, and adjustment of network traffic based on set constraints, which improves network resource utilization. In addition, it provides differentiated SLA guarantees, makes network resources manageable and visualized, and greatly increases the efficiency of O&M. The Network Cloud Engine-IP uses an open architecture to support basic network services and northbound standardization and enables network northbound openness to reduce the difficulty of interconnection. It also provides customers with a ROADS experience.
The Network Cloud Engine-IP presents a layered visualization of network-wide resources, which includes physical topology, logical topology, tunnels, and VPN services, to facilitate management and planning. It automatically discovers network resources, which increases O&M efficiency and reduces the time required for initial network configuration.
The Network Cloud Engine-IP abstracts forwarders and services, provides a network-level service interface in the northbound direction that is standardized and unified, and allows automated and on-demand provisioning of VPN services.
The Network Cloud Engine-IP provides intelligent network optimization for IP and MPLS networks, allowing the automated, real-time optimization of network traffic in addition to the collection and presentation of SLA information.
