Cisco Active Network Abstraction is the Cisco IP Next Generation Network (IP NGN) infrastructure manager. Designed for service providers, it provides network management for IP NGN infrastructure networks out of the box. Cisco ANA supports all major Cisco service provider network elements, Multiprotocol Label Switching (MPLS), carrier Ethernet, and unified RAN backhaul reference architectures. It offers comprehensive functions in element, network, and service management.
Cisco Active Network Abstraction serves as the foundation of modern, efficient, multilayer, multiservice, and multivendor carrier management stacks. This helps the IP NGN to reliably deliver services and yield significant savings in capital and operating expenditures.
Mediation and information model
Cisco ANA operates between the network and the operations support layer. Its virtual network abstraction model is built, bottom-up, as an aggregation of independent virtual network elements (VNEs) creating an end-to-end software-based virtual network much in the same way real network elements create the real-world network. Cisco ANA dynamically discovers and identifies device and network components and technologies and maintains its model of the network elements in near real time. This abstraction model supports Cisco ANA's own element management features and provides network mediation for other value-added network and service management applications through standard, open interfaces.
Network discovery and visualization
Based on an initial seed list, Cisco ANA discover multivendor devices and will use various algorithms to discover adjacencies, connectivity, and the physical and logical topology of the network, including routes, Virtual Route Forwarding (VRF) tables, and Virtual Private Network (VPNs).
The Cisco ANA VNEs autodiscover and maintain a detailed physical inventory model, down to fans, slots, cards, and ports, and a comprehensive logical networking model and configuration, by polling of routing, bridging, and Label Switch Entity (LSE) tables, as well as hundreds of other device properties. Both the physical and logical inventory models are continuously updated for status and configuration. Changes are detected and reflected in the exposed network model and reported in the form of alarms and northbound interface notifications.
Fault analysis, event reduction, and alarm correlation
Cisco ANA captures, annotates, and forwards event notifications (traps and syslogs) and provides extensive element and topology-based fault detection, analysis, and isolation as well as root-cause correlation, resulting in significant event filtering and reduction in the number of trouble tickets that need to be tracked. Extended to end-to-end fault analysis for layer 3 MPLS/VPN, carrier Ethernet, and MToP, Cisco ANA offers a comprehensive service-aware fault management solution for device, network, and services. What-if fault scenarios can be explored with the Cisco ANA impact analysis tool. Cisco ANA can rapidly be integrated with OSS fault systems.
Flexible integration through standards-based interfaces
Designed for deployment in service provider networks, Cisco ANA integrates through Simple Network Management Protocol (SNMP) or an XML-based API with northbound management applications. The TMF-compliant inventory and fault information model, as well as the activation framework, are programmatically accessed through a simple, open XML-based API. The near real-time nature of the VNE model and the XML-based API provide an ideal mediation and integration point for a variety of valued-add applications, including trouble ticketing or "manager of manager" systems, provisioning systems, and inventory systems.
Scalable and distributed management architecture
Cisco ANA achieves its end-to-end visibility of network resources through scalable and distributed management architecture, consisting of multiple unit servers, which host the VNEs, and the Cisco ANA gateway server.
Virtual network elementsProduct Highlights
VNEs are the building blocks of the Cisco ANA virtual network model. They are software-based virtual network elements, communicating with their real-world counterparts through Telnet/Secure Shell (SSH) Protocol and SNMP for configuration and status. VNEs run autonomously within unit servers and communicate among themselves for end-to-end algorithmic flows supporting root-cause and impact analysis, service path tracing, and other value-added applications.
