Cisco Active Network Abstraction

Cisco Active Network Abstraction

Service providers face many challenges introducing new services and evolving existing ones. The volume of services and the pace of innovation are accelerating, and IP next-generation network (NGN) service architectures are increasingly complex to operate. Disjoint management solutions increase integration and operations costs, while internally developed manual processes and reactive troubleshooting lead to expensive service delivery outages. Operators require integrated, comprehensive, and interlocked network management solutions.

Cisco® Active Network Abstraction (ANA) provides service providers and other carrier-grade network operators with a comprehensive, network management solution for IP next-generation networks. ANA creates and maintains an accurate, "virtual" abstract model of the network in near real time to:

• Manage network elements: Supports all major Cisco service provider network elements, Multiprotocol Label Switching (MPLS), Carrier Ethernet, and Cisco Unified Radio Access Network (RAN) Backhaul reference architectures.

• Manage networks and services: Integrated networkwide and servicewide monitoring and fault analysis

• Integrate with network management systems (NMSs)/OSSs: Uses a standards-compliant information model for integration with third-party products, and ANA is easily field customized with built-in tools or through the Cisco partner program and Cisco Advanced Services support.

ANA's service-aware design and abstraction support converged core, aggregation, and access networks (see Figure 1).

Figure 1. Cisco ANA's Service-Aware Design

Installed on carrier-class servers, Cisco ANA is highly distributed, providing resiliency, high availability, and scalable deployments with the ability to support thousands of network elements (NEs).

Cisco ANA Benefits

Cisco ANA brings both functional excellence and operational efficiency to network operations. Specific benefits include:

• Single management application for the converged network: Cisco ANA is the management application for the converged network, supporting all service provider IP NGN deployments, such as IP/MPLS core and service edge networks, IP RAN backhaul, and Carrier Ethernet networks. Cisco ANA provides management at the element, network, and service level. It supports the service assurance lifecycle from fault detection, event association, and root-cause analysis to remediation. The management architecture is simplified to one application - Cisco ANA - reducing the number of disjoint applications.

• Network visibility: Using Cisco ANA, users have the needed network information at their fingertips. Cisco ANA's unique model-based virtual network abstraction represents a live information foundation, providing a consistent and complete end-to-end topological view of the network resources, technologies, and services.

• Reduce operating expenses: Cisco ANA helps ensure operational efficiency and speeds up troubleshooting with its fault analysis, alarm correlation capabilities, and diagnostic tools. It reduces the Mean Time to Repair (MTTR) for service problems and thus decreases the cost of trouble tickets.

• Easily customizable: Cisco ANA is flexible and easily adaptable in different deployment scenarios. Cisco ANA is customizable to facilitate deployment in a variety of network scenarios. Its standards-based information model is easily extensible, and with its XML-based API, it provides an effective mediation and integration point for the OSS/BSS layer. Cisco ANA can be deployed along with service provisioning systems, inventory, and performance management systems, for complete management of next-generation IP networks.

Cisco ANA Features at a Glance

Cisco ANA offers service providers a basic Element Management module, with which Cisco network elements such as the Cisco CRS-1, 7600, and ASR 9000 families can be managed. Additionally network and service management are available with the Network and Service Monitoring module.
Tables 1 and 2 summarize the features of Cisco ANA available in each module.

System Requirements

Scalable and Distributed Architecture

Cisco ANA has a scalable and distributed architecture. Each Cisco ANA installation consists of unit servers, which host the VNEs, the gateway server, an embedded database or an external Oracle database, and Windows-based clients. Cisco ANA supports virtualization using either Solaris Logical Domain (LDOM) or VMware for Linux, thus allowing gateway and unit servers to be deployed as virtual servers. Cisco ANA can support a wide variety of deployment configurations tailored to each customer environment; the system requirements for Cisco ANA differ, depending on the actual type and size of deployment. Tables 3 through 6 list the minimum Cisco ANA 3.7.3 system requirements. The system can be set up in various standby (high availability) modes to help ensure business continuity.

Unit Servers

The interconnected unit servers (units) can host up to thousands of individual VNEs, each representing a managed network element. As the managed network grows, VNEs can easily be moved from one unit to another, and additional units can be added to host additional VNEs.
