Product overview

SeerNetwork Architecture (SNA) is the next-generation intelligent network architecture launched by H3C. As a core component of SNA, SNA Center provides unified management, control, intelligent analytics, and service orchestration capabilities for the entire network. Boasting a global perspective, SNA Center can coordinate resources across management domains to simplify O&M and reduce operating expenses. SNA Center provides real-time network monitoring and intent- or status-based analytics to enable automated service deployment and risk prediction, helping the network to serve critical businesses more concisely, intelligently, and efficiently.

Features and benefits

Leading, open software architecture

* Northbound RESTful API—Through a high-performance API gateway, SNA Center provides standard northbound RESTful APIs to allow cooperation with third-party O&M systems, enabling programmable automation of the SNA network.

* Southbound RESTful API—SNA Center provides abundant southbound RESTful APIs compliant with various protocol standards including NETCONF, OpenFlow, BGP-LS, PCEP, and SNMP. Those southbound APIs makes SNA Center compatible with third-party devices of different vendors and models.

* Containerized, mircoservice-based architecture—Based on a containerized, mircoservice-based architecture and AI-assisted data analytics, SNA Center can flexibly provision a variety of network applications to suit the needs of various scenarios. It provides an open development environment and various development tools, which enables third-party systems to develop their customized applications on the SNA Center platform.

Cross-technology, cross-domain integration of service functions

* Cross-technology—By integrating the control, management, and analysis technologies, SNA Center integrates the traditionally fragmented deployment, management, and O&M functions. It provides a unified entrance and interface for the entire IT process encompassing service design, configuration deployment, and business assurance.

* * Cross-domain—By integrating services across domains such as DCs, campuses, and WANs, SNA Center can take comprehensive consideration of various business needs to deliver cross-domain, end-to-end business design, deployment, and assurance capabilities. [1]

Full lifecycle management

* SNA Center provides full life cycle management for services covering from users' business needs to closed-loop processing of problems, integrating capabilities including business design, simulation, deployment, assurance, and closed-loop control. It provides comprehensive services for users and enables zero touch provisioning of networking devices and services.

AI-empowered

* Automatic problem detection, location, and early warning—SNA Center can nip problems in the bud through automatic problem detection, location, and early warning empowered by the AI technology.

* * Sharing of the global top-class network O&M experiences—Connected to the global version-based defect and problem database, the SeerEngine allows enterprises of all sizes to share the global top-class network O&M experiences.

* * Intelligent network evolution—User data is desensitized and uploaded to the cloud AI intelligent sharing platform to implement cloud training of intelligent models. The intelligent training results are delivered to users' local devices in real time to realize the intelligent evolution of the network.

Comprehensive data analytics

* Real-time network monitoring and problem detection—By using the big data technology, SNA Center can capture, store, and analyze massive network data to monitor the network status and detect problems in real time to implement fine-grained O&M control.

* Running status tracing of the whole network at any time—By enabling running status tracing of the whole network whenever and wherever that is needed, SNA Center allows you to easily perform problem analysis, performance analysis, and behavior audit to meet specific network maintenance needs.

* Business value discovery and network intelligence promotion—The network operation data accumulates with the network operation time, and finally form the base data that can be used for data mining and AI training. The data mining and AI training results can be used to discover new business values and further promote network intelligence.

Cloud-native platform-based

* Agile—Based on the DevOps methodology, SNA provides continuous service delivery, rapid service provisioning, and smooth service upgrade, making user services more agile.

* Scalable—Stateless applications use containers as the basic units and can be easily scaled.

* Rapid failure recovery—In the micro-service architecture, services are isolated from one another so the impact of individual service fault is limited.

Typical applications

* Cross-domain service orchestration

[2]

Cross-domain service orchestration architecture

* As the single entrance for cross-domain, end-to-end service design, deployment, and assurance capabilities, SNA Center enables WYSIWYG design of services tailored to users' requirements as well as cross-domain coordination, scheduling, visualization, and optimization of services and resources.

* Controllers in different domains are responsible for the abstraction and management of the physical network, and implementing programmable, automated provisioning of services. The optimal path scheduling of traffic is achieved by visualizing the physical and logical topology of the entire network.

* The network infrastructure is responsible for providing rich terminal access methods, forwarding bandwidth-intensive, delay-sensitive data, and enabling rich and varied data capture capabilities through Telemetry and other means.

Finally, SNA Center allows you to design cross-domain services once and then run the services whenever and wherever they are needed. Services can be provisioned and delivered to users easily with just a few clicks and the entire process is automated without manual switching among multiple systems. Based on graphical user business design templates that incorporate rich data analysis algorithms, SNA Center products provide online business design and simulation capabilities to meet flexible and diverse user business needs.
