T-SDN（Transport-Software Defined Networking）It is a key enabling technology for the evolution and innovation of the transport network architecture. It breaks through the traditional closed architecture and will construct a more open, cooperative and more automatic transport network, which is one of the important characteristics of the next generation transport network.
Agile Controller-T collects network parameters from network elements in real time to achieve unified scheduling and control of network resources. The Agile Controller-T can optimize the network performance, reduce the cost of network operation and maintenance, and support the construction of open ecosystem. .
Key Features
On-demand: Build on-demand transport networks with the BoD (bandwidth on demand) feature. Large customers can complete the business self-service release, significantly reducing business time to market; at the same time according to real-time changes in traffic to adjust the transmission pipeline to meet the sudden flow demands.
Efficient: built-in centralized algorithm, centralized control and ASON + T-SDN dual protection, re-routing success rate increased by 10%. Support IP + optical multi-layer multi-domain centralized management, network efficiency increased by 40%, the business release to achieve minute-level experience.
Open: equipment / network / business model and the three-tier model based on YANG standard northbound interface to build an open application platform.
Security: 99.9999% of carrier-class reliability is achieved through local clustering, intra-city dual-center, and off-site disaster recovery. Through the multi-layer security mechanism, to build a three-dimensional security depth defense system.
Technical specifications
BoD | BoD（Bandwidth on Demand），Bandwidth distribution according to demand function, mainly used in green line, DC interconnection scenes. Support a key to quickly release business, according to need to adjust the bandwidth, business booking and other functions. The BoD function of SDN can provide transmission pipeline on-demand in real time to meet the needs of rapid service issuance. Real-time rapid adjustment of bandwidth, to achieve green business from the operation. Set a time policy to implement scheduled service delivery or service bandwidth adjustment

Automation operation and maintenance | Master the whole network resource information, use the advanced algorithm to carry on the dispatching and optimization to the whole network resources, greatly simplify the operation and maintenance. ● Centralized rerouting: The advanced PCE algorithm is used to calculate the optimal path of a service to improve the rerouting success rate and the resource utilization rate. Survivability Analysis: Agile Controller-T supports network survivability analysis and resource early warning. Through resource simulation analysis (such as fiber cut), users can assess the survival of the business status and resource consumption, real-time analysis, fault simulation and early warning, network automation operation and automation. Optical fiber cutover: Agile Controller-T master the whole network link and business information, you can find all the services on the specified fiber, in the physical fiber cut before these services removed, physical fiber cut after the completion of Business migration back, making real-time business operations and greatly enhance the user experience.

Resource visualization | Layer-by-layer visibility of the entire network resources, and full monitoring of network performance through the entire network resource view. It supports real-time status of resource display, resource utilization, such as resource wavelength / subwavelength / port. Support real-time monitoring of the whole network business performance, business delay, packet loss rate, jitter and other KPI indicators at a glance. |
