Converged Backbone Network

Converged Backbone Network

Converged backbone networks are complex in terms of structure and O&M. Each type of service is carried by an independent network, resulting in many dedicated networks and devices. Services are subject to changes, making it difficult to plan services and time-consuming to deploy and integrate new services. Moreover, backup resources are redundant. All these lead to slow service deployment, low network resource efficiency, difficulty in application innovation, complex O&M, and high network OPEX.
The converged backbone solution of iMaster NCE offers simplified service provisioning, network path optimization, and open programmability to help carriers improve provisioning efficiency, simplify deployment as well as southbound and northbound integration, accelerate service rollout, and achieve business success.

Key Features

Simplified Service Provisioning

iMaster NCE uses service templates to automatically map common parameters. Layered service, network, and device models reduce service provisioning parameters from over 100 to just 10 or more. Automatic path computation and tunnel creation based on SLAs make it possible to provision services with just a click. To avoid long labels in cross-domain scenarios, iMaster NCE combines node and link labels to compress the entire label stacks by 80%.

Network Path Optimization

By introducing protocols such as BGP-LS and IFIT, iMaster NCE draws a real-time digital map of the live network to guide automatic scheduling of network traffic and paths. Through real-time collection of 80,000+ KPIs, the digital map provides visibility into five layers: NE, network, protocol, slice, and service. No matter what changes occur on the network, users can learn of the changes from the map. In addition, to support accurate path computation, the digital map encompasses 15+ factors. It can automatically plan network paths as required, optimize millions of tunnels, and converge faults at the sub-second level. In the planning phase, it automatically analyzes congestion points, facilitating accurate capacity expansion. In the O&M phase, it detects network changes in real time and quickly relieves congestion to better balance network loads.

Open Programmability

In the agile cloud era, SDN-based automated service deployment and fast, agile, automated, and intelligent service O&M are the key for carriers and enterprises to build up their core competitiveness. The service and O&M capabilities in vendors' network management and control systems may fail to meet customers' diversified, fragmented, and custom requirements. To meet the preceding open programmability requirements, iMaster NCE provides an open programmable framework that vendors can use to customize network services based on their O&M habits and requirements, and deploy and provision network services from their own perspective. This framework provides one-stop device management and control as well as service provisioning in multi-vendor scenarios.
