Virtualization and cloud create exciting business transformation opportunities, innovative service delivery models, and improved economics. At the same time, they introduce a new dimension of service delivery challenges that demand real-time applications and network visibility to boost operational agility.

Product Overview

Cisco Prime Virtual Network Analysis Module (vNAM) delivers operational agility by permitting deployment anywhere in the network to improve service levels. You can deploy the vNAM in the cloud to monitor hosted workloads, at remote sites to characterize the end-user experience, or wherever you want in the network to eliminate blind spots. It combines comprehensive application awareness, rich performance analytics, and deep network visibility, empowering network administrators with actionable information to effectively manage their networks.

Cisco Prime vNAM’s versatility allows you to:

   Monitor workloads in the multitenant cloud

   Understand traffic behavior within overlay technologies such as VXLAN, LISP, and OTV

   Analyze network usage by application, host or virtual machine (VM), and conversation to identify bottlenecks that may affect performance and availability

   Troubleshoot performance problems by combining detailed traffic flow and packet analysis consistently across physical and virtual environments

   Validate infrastructure updates such as WAN optimization, Cisco TrustSec®, and quality-of-service (QoS) policy changes

   Take advantage of an integrated web-based interface to manage a site remotely, eliminating the need to backhaul the data to a centralized location, hence saving WAN bandwidth

Cisco Prime vNAM offers a comprehensive package with extensive data-collection capabilities, rich analytics, and user experience that help enable you to get actionable information quickly to accelerate operational decisions. The key features are described in Table 1.

Table 1.       Cisco Prime vNAM Features and Benefits



Deployment versatility

Meet the demand for operational agility in virtualized data center and cloud environments. You can deploy Cisco Prime vNAM in the tenant network containers, remote sites, or almost any place in the network to address specific operational needs with its rich analytics and purpose-built GUI.

Application performance analytics

Characterize the end-user experience for TCP-based applications and isolate application response-time problems to the network, server, or the application, to accelerate troubleshooting.

Voice quality analytics

Gather real-time reports on mean opinion score (MOS) and other key performance indicators (KPIs) such as jitter and packet loss to understand and improve how the end user experiences the delivery of voice services. MOS is computed based on ITU-T Recommendations G.107, offering accurate characterization of voice quality.

Traffic analysis

View short- and long-term network usage by applications, hosts, conversations, differentiated-services-code-point (DSCP) groups, and various supported encapsulations. Identify top consumers of network resources and isolate network bottlenecks, thereby allowing you to optimize network resource-allocation decisions.

Insight into encapsulation and overlay technologies

Design overlay networks for efficient delivery of applications. Supported protocols include OTV, LISP, VXLAN, CAPWAP, and others.

Cisco TrustSec policy validation

Validate the Cisco TrustSec policy using Security Group Tag (SGT) and evaluating the endpoints or hosts, applications, and conversations participating in one or more security groups.

WAN-optimized network visibility

Obtain end-to-end proof points demonstrating how Cisco Wide Area Application Services (WAAS) has improved application delivery (for example, decreased application transaction times or improved WAN bandwidth usage). Accelerate your return on investment (ROI) by assessing the best site and application candidates for optimization as part of the phased rollout plan.

Deep, insightful packet analysis

Solve complex performance problems with trigger-based captures, filters, decodes, and error scan features. Packet captures can be triggered based on performance thresholds, allowing you to focus on specific performance problems. In addition, use external storage to collect extensive packet captures for offline analysis.

Open interface

Preserve investment in existing management assets through integration based on a standards-based REST/XML) API.

Any time, anywhere access

Access the web interface from any desktop, eliminating the need to send personnel to remote sites or send large amounts of data over WAN links to the central site.

Example of Deployment Scenarios

Monitor Workload in Multitenant Cloud

Deployed in the tenant network container (Figure 1), Cisco Prime vNAM analyzes the TCP-based interactions for the hosted workload to monitor performance in terms of metrics such as transaction time, server response time, and application delay. Setting performance thresholds helps to proactively detect performance problems, troubleshoot application response time concerns, and minimize the risks of violating service-level objectives. Cisco Prime vNAM also provides insight into network usage by applications, top talkers, and conversations to help optimize use of cloud infrastructure, including overlay technologies such as VXLAN and LISP.

Simplify Remote-Site Manageability

When deployed at a remote site, Cisco Prime vNAM can help network administrators characterize end-user experience (Figure 2), profile application traffic, and troubleshoot performance problems to cost-effectively deliver services across Cisco® Borderless Networks. An integrated web-based interface allows administrators to access vNAM remotely at any time and from anywhere to get a glimpse into the health of the network and applications. It eliminates the need to bring the data to a centralized location for analysis. The vNAM provides the ability to monitor all traffic entering and leaving the remote site, understanding what applications are consuming the most bandwidth, proactively identifying when application performance is being affected, assessing whether the control and optimization techniques are effectively implemented, and contextually troubleshooting the performance problems.
