5G Transport


5G Transport

With the release of the 3GPP R15 standard, commercial use of 5G is gathering pace. Transport networks, however, must be in place before 5G can be commercially deployed. The industry expects that the first commercial use of 5G will be in eMBB scenarios and that technical validation will be performed for other scenarios, such as URLLC and FMC. iMaster NCE (IP Domain) meets the requirements to manage 4G and 5G services in a unified manner. It supports 4G service automation and restoration and delivers 5G-oriented SR+EVPN simplified service provisioning. It also supports fault demarcation within 30 minutes through quality deterioration analysis and SLA recovery within minutes through network optimization. As the O&M center for transport networks, iMaster NCE (IP Domain) provides SLA-based intelligent O&M capabilities and automatically partitions the physical network into slices based on service intents, meeting the requirements to isolate service traffic on the 5G network while also ensuring service latency and security. With iMaster NCE (IP Domain), carriers can automate legacy and new services and smoothly evolve to 5G networks.

Use Cases

Simplified Service Provisioning

NCE (IP Domain) abstracts forwarders and services to provide unified, standard network-level service interfaces for self-provisioning of mainstream services. It provides multiple templates for service configuration and supports automatic parameter verification, effectively improving the service provisioning efficiency. Service-driven tunnel creation also helps to significantly reduce the time required to provision services. During service provisioning, NCE (IP Domain) centrally computes paths and overlays path computation results on a mapping service like Google Maps to facilitate decision making on optimal paths. For VPN services, NCE (IP Domain) provides one-click connectivity checks and supports BOD and QoS profiles.

MPLS Network Optimization

NCE (IP Domain) uses the innovative Routing Optimization Algorithm Based on Matrix (ROAM) algorithm to provide unified management, real-time analysis, and centralized path computation for MPLS TE networks. It computes E2E optimal paths for MPLS TE tunnels based on factors such as bandwidth, delay, cost, and priority to ensure optimal service paths and globally balanced traffic distribution. It also provides differentiated service management to ensure that high-priority services are scheduled first.

Intelligent Online Simulation

NCE (IP Domain) parses the existing network, configuration, and traffic information, restores the entire network topology and protocols, and analyzes the impact of network changes on services by simulating faults on key NEs and links. It also compares and analyzes network-wide traffic, load, and tunnel paths before and after a fault occurs. This helps O&M personnel clearly understand the impact scope and evaluate the risks of devices and links, and formulate appropriate capacity expansion policies and maintenance measures to improve service reliability.

Intelligent Analysis and Forecast

NCE (IP Domain) uses the AI algorithm to build traffic models based on historical traffic data and forecasts traffic over the next one to three months based on traffic curves obtained from big data analytics. With accuracy of over 80%, NCE (IP Domain) can forecast bandwidth usage and the time when link capacity will reach the bandwidth usage threshold, providing effective means for network capacity evaluation. This allows carriers to identify network bottlenecks before they occur, perform network planning accordingly, and expand network capacity proactively and precisely.
