Apparent Networks’ AppCritical: Handling the New Management Realities for Application Services

This white paper looks at key industry trends as the market is evolving to support Networked Application Management (NAM)—both in terms of increased requirements for business alignment and new technologies. The paper then discusses Apparent Networks’ AppCritical solution, which provides an easy, unrestricted deployment across any network while giving network operations staff and application owners an end-to-end, unbroken view of their networking infrastructure from the perspective of the applications that operate on it.

Driving The Performance Cycle: The Three Layer Quality Model

This whitepaper aims to clarify and simplify the challenge of application performance monitoring by distinguishing between Quality of Service (QoS), Quality of Experience (QoE), and most recently Quality of Application (QoA).  Using the Three Layer Quality (TLQ) model, it demonstrates how the complex and sometimes overwhelming job of assuring end-user satisfaction can be reduced to a simpler set of tasks.  The TLQ model provides a clear relationship between QoS, QoA, and QoE that has otherwise been lacking.

Managing Performance in Converged Networks:
Not Your Father’s NMS

This whitepaper contrasts the radical changes in the network environment, compared to just a decade ago, with the limited progress made by network management systems (NMS). Where NMS might once have been effective, they are now woefully inadequate in meeting the needs of today's applications and end-users. The latest generation of management solutions focus on network performance and the measurement of indicators essential to specific applications such as VoIP. No longer simply about element management, these new Network Performance Infrastructures (NPI) provide direct evidence of a network's ability to support critical applications. Get white paper

Two Unique Eyes: One Network Vision

This whitepaper describes the potential benefits of merging two unique technologies - end-to-end network performance analysis and topological network analysis. Both Apparent Networks and Solana Networks offer highly effective forms of network visibility, each addressing a distinct set of network characteristics and behaviors that are critical to network and application management. By combining the two into a single "pane of glass", details of the network and related application behaviors can be resolved into a high resolution image that captures the full breadth of the underlying infrastructure - non-intrusively, real-time, point-and-shoot, with almost no instrumentation, across networks that you don't own, and with no a priori knowledge.
