Network Cloud Engine-Transport
Network Cloud Engine-Transport is a key part of transport networks evolving towards software-defined networking (SDN) and is applicable to backbone, metro, and enterprise access networking scenarios. It provides a variety of functions and features, such as real-time resource visualization, fast service provisioning, and automatic network O&M to meet new requirements on innovative service experiences and flexible and efficient networks, proposed by enterprise private lines and DC interconnection.
Transport-Software-Defined Networking (T-SDN) is the key driver for evolution and innovation of next generation transport networks. T-SDN technology breaks through the traditional closed architecture and enables construction of a transport network that is more open, synergetic, and automatic. T-SDN is one of the most important features of the next-generation transport network.
The Network Cloud Engine-Transport virtualizes physical devices, collects network information from NEs in real time, and uniformly controls network resources to achieve optimal network resource utilization, significantly reducing network O&M costs and facilitating development of an open ecosystem.
The bandwidth on Demand (BoD) feature helps VIP customers provision services within minutes, significantly shortening the Time-To-Market (TTM). With this feature, transport bandwidth can be adjusted in real time, preventing congestion in case of burst traffic.
Featuring a centralized and advanced algorithm, the Network Cloud Engine-Transport implements centralized network management, ASON + T-SDN dual protection (increasing the rerouting success rate by 10%).
The three-layer model (device/network/service) and standard Northbound Interfaces (NBIs) are based on the YANG model, facilitating development of an open application platform and enabling users to focus on services.
|BoD||The Network Cloud Engine-Transport supports BoD, which is mainly applied to private line carrier and DCI scenarios. The Network Cloud Engine-Transport also supports functions such as one-click fast service provisioning, on-demand bandwidth adjustment, and reserved service provisioning.
Provides transport pipes on demand and in real time, adapting to requirements on fast service provisioning.
Adjusts bandwidth quickly in real time, achieving self-operation of private line services.
Sets time policies, achieving scheduled service provisioning or service bandwidth adjustment.
|Automatic O&M||The Network Cloud Engine-Transport can obtain network-wide resource information and therefore can use advanced algorithms to schedule and optimize network-wide resources, greatly simplifying O&M.
Centralized rerouting: The Network Cloud Engine-Transport uses the advanced PCE algorithm to compute the optimal service path, improving the rerouting success rate and resource utilization.
Survivability analysis: The Network Cloud Engine-Transport supports network survivability analysis and resource warning. Users are allowed to evaluate service survivability status and resource usage status by means of simulated resource analysis (such as fiber cut). Real-time analysis, fault simulation, and warning enable proactive and automatic network O&M.
Fiber cutover: The Network Cloud Engine-Transport can obtain network-wide link and service information, find all services that traverse the specified optical fiber, migrate these services before a physical fiber cutover, and then migrate them back after the fiber cutover is completed. This significantly improves the service operation efficiency and user experience.
|Resource Visualization||The Network Cloud Engine-Transport supports layered visualization of network-wide resources and comprehensively monitors network performance using the network-wide resource view.
Displays real-time status of network-wide resources and utilization of resources such as wavelengths, sub-wavelengths, and ports.
Monitors network-wide service performance and clearly displays Key Performance Indicators (KPIs) such as service latency, packet loss ratio, and jitter.
