Cisco Active Network Abstraction 4.0 Product Overview Cisco Active Network Abstraction (ANA) is a flexible, vendor-neutral network resource management solution for a multitechnology, multiservice network environment. Operating between the network and the operations support system (OSS) layer, Cisco ANA aggregates virtual network elements (VNEs) into a software-based virtual network, much as real network elements create the real-world network (Figure 1). Cisco ANA dynamically discovers network components and tracks the status of network elements in near real time. Cisco ANA also provides platform and network mediation services for both Cisco applications and value-added applications from Cisco partners. Cisco ANA offers service providers: Simplified integration of OSS applications with network information A flexible common infrastructure for managing network resources Consistent procedures and interfaces for all network elements Figure 1.

Cisco Assurance Management Solution, combining products from Cisco and IBM Tivoli, is available only when integrated with Cisco ANA. Cisco Assurance Management Solution provides extensive topology-based fault analysis capabilities for rapid and extensive fault detection, isolation, and root-cause correlation. Its Manager of Managers feature helps operators focus on important network events, offering a combination of alarm reduction rules, filtering, customizable alarm viewing, and partitioning. These features can be extended to include Layer 3 Multiprotocol Label Switching (MPLS)/VPN fault analysis, creating a comprehensive fault management offering for network elements, networks, and services. Standards-Based Access to Near Real-Time Network Element and Network Information Cisco ANA provides value-added applications with standards-based access to real-time information on the network, network elements, slots, and ports. This information supports networking technologies that include IP, Packet Over Sonet, Hot Standby Router Protocol, Ethernet IEEE Dot1Q / VLAN, Ethernet channel, MPLS, and routing protocols such as Border Gateway Protocol (BGP). Thanks to this access to information, Cisco ANA eases the integration burden associated with traditional network management systems through standards-based APIs that provide: Real-time mediation to network element/network inventory and discovery information, a key value-add to offline inventory applications Real-time, distributed alarm surveillance and domain-specific root-cause analysis within value-added fault management applications Real-time, workflow-enabled service activation and network configuration engine for valueadded provisioning applications and processes to push activation commands to network elements Table 1 lists the features and benefits of Cisco ANA 4.0. Table 1.

Standards-based access to realtime network element and network information Distributed and scalable architecture Provides real-time mediation to network element/network inventory and discovery data, adding value to off-line inventory applications. Provides real-time, distributed alarm surveillance and enabling technology for domain-specific root-cause analysis within value-added fault management applications. Provides a real-time, workflow-enabled service activation and network configuration engine. Standard WSDM based northbound interface provides a single network element mediation platform for all supported network elements. Standard northbound interface reduces OSS/BSS integration complexity. Eliminates use of a single point for computation in managing multivendor networks. Allows network operators to expand core networks, and manage them effectively, with low incremental cost. Hot standby system enables services management and business continuity. Platform Architecture The core technology of Cisco ANA provides end-to-end visibility of network resources, connections, and dependencies through a scalable and distributed management platform architecture consisting of virtual network elements (VNEs), VNE server units, and the Cisco ANA Gateway appliance (Figure 2). The building blocks of the Cisco ANA virtual network model are software-based VNEs that clone the characteristics and properties of their real-world counterparts. These entities run autonomously within Cisco VNE server units. Each VNE is assigned to manage a single network element instance using southbound management interfaces implemented by the network element such as Simple Network Management Protocol (SNMP) or Telnet. Messaging between VNEs is used for running different end-to-end algorithmic flows, providing information for root-cause and impact analysis, service path tracing, and other uses in value-added applications. The VNE server units can host thousands of VNEs and are interconnected to form a fabric that can intercommunicate with other VNEs regardless of which unit they are running on. VNE server units also allow for optimal VNE distribution, helping ensure geographic proximity between VNEs and their managed network elements. The Cisco ANA Gateway is a server unit through which all applications (including any OSS/BSS applications as well as service management applications for Cisco ANA and clients) access the system, enforce access control and security for all connections, and manage client sessions. In addition, it functions as a repository for configuration, network, and system events and alarms. The Cisco ANA Gateway is also used to map network resources to the business context, allowing Cisco ANA or service management applications for Cisco ANA to take information that is not directly contained in the network (such as VPNs and subscribers) and display it to northbound applications.
