IT organizations have spent billions of dollars implementing fault management tools and processes to maximize network availability. While availability management is critical, infrastructure reliability has improved to the point at which 99.9% availability is not uncommon. Given these improvements in device availability, companies are focusing more attention on performance management. In this whitepaper, you’ll see why this shift is taking place now and how to use a new Performance-First model that will enable you to manage your network for application performance.
Start effectively managing VoIP with the new, free VoIP ebook from NetQoS. You’ll learn which protocols are used for VoIP communications and how they affect network performance.
An important part of shifting a network management strategy from up/down availability measurements to one based on performance is moving beyond a limited, “device-aware” approach to a focus on application delivery—an “application-aware” approach. This white paper introduces a set of application-aware capabilities, explains how they can be leveraged within Cisco routers and switches, and outlines their critical role in an overall application delivery management strategy.
Echo is a troubling problem for telecom professionals. Most of us have suffered through a telephone call where we had to try to talk with a lot of echo on the wire. It’s very distracting. This white paper gives an overview of echo issues, provides a brief introduction to echo cancellation, and describes the echo metrics provided by the NetQoS® Unified Communications Monitor VoIP management solution.
In this white paper, we define the issues and outline the capabilities required to effectively manage the delivery of electronic trading applications and order management systems.
In short, VoIP is the most demanding application in your portfolio requiring optimal network performance, and the highest possible quality of service levels to deliver an acceptable quality of experience. As such, VoIP and its related applications can present a considerable challenge for those charged with managing the performance of business-critical data applications running on your converged enterprise network.
This paper examines the concept of Retrospective Network Analysis (RNA)—capturing and storing significant network traffic data to be analyzed at a later date—and illustrates how using GigaStor to enable RNA can help network engineers streamline network troubleshooting. It also details critical issues IT managers should consider when choosing an RNA solution.
Business transaction monitoring has never been more critical to operational efficiency, yet there remains much confusion over methodology. The implementation choices consist of different deployment strategies (client-site or server-site, agent, or appliance) and distinct monitoring technologies (active or passive). The different options have their individual strengths and weaknesses. This article discusses industry best practices for effectively monitoring business transactions in a global environment.
The result of insufficient visibility can have unexpected and costly consequences. This paper broadly identifies the key diagnostic information that is necessary to provide proper visibility into network performance.
Discover techniques for risk-proofing your VoIP deployment and ensuring the performance of latency-sensitive VoIP applications. Find out how to mitigate the impact of VoIP on existing mission-critical applications using this proven performance first approach.
IT Managers and network administrators are constantly making decisions affecting critical business activity on the network. The key to confidently managing network issues is complete visibility into the network.
Moving to an MPLS environment offers a host of benefits to enterprise customers, but how do you verify that your services offered are performing as users have come to expect?
Because the network backbone spans the entire business operation, when something goes wrong, the network is usually the first to take the blame from end users. Learn how to clear your network's good name by quickly identifying if the problem is in the network, the server, or the application.
Describes how to implement the right Service Level Agreements (SLA) for your enterprise. With Service Level Management (SLM) garnering widespread attention as a method to align IT resources with business goals, it is now time to think of how to implement SLAs. Successful SLM requires a proactive approach, measuring the right metrics while avoiding common pitfalls. “Improve Networked Application Performance through SLAs,” describes how to transform your team from firefighters to advanced planners with the appropriate tools.
Describes the general capabilities to look for in any end-user monitor as well as industry best practices to significantly reduce operating costs, achieving a return on investment in less than 30 days.
