Denise Culver | Research Analyst
Many IPT managers are turning to service-level reporting (SLR) to learn as much as possible about the quality issues on their networks.

SLR does more than just rely on the time-honored break/fix philosophy of quality-of-service (QoS): It provides a number of comprehensive ways to assess QoS.

Diagnosis Quality: Service-Level Reporting Delivers
While it is doubtful that any IP telephony (IPT) manager ever developed a network without giving thought to quality of service (QoS), quality of experience (QoE), or other quality metrics, it is a fact that quality has not always been on equal footing with other issues in network development. After all, network developers must consider issues such as performance and optimization, security, and how the network will be managed when building out their systems, so it is not surprising that reliability and availability have taken a back seat.

Most SLR vendors claim that their product enables users to save money, but it is difficult to illustrate how such solutions provide savings in terms of capital expenditure (capex), operational expenditure (opex), and other areas.

Although the types of solutions vary, IPT managers considering SLR solutions should consider a couple of goals when choosing a solution. First, they should determine which solution will enable them to best measure QoS, QoE, and other quality metrics within their networks so that performance and optimization, security, and network management will all benefit from the SLR solution. Additionally, they should consider which solution provides the optimal analytics in a format that works for their organization. Input should be gathered from various levels to determine what works best to accomplish organizational goals. IPT managers can use capacity planning and analytics reports to develop future network plans and ensure that there is adequate network space, while controlling the budget.

Diagnosis Quality: Service-Level Reporting Delivers provides an in-depth look at the SLR market, including a comparative analysis of solutions. It also examines the vertical market strengths and strategies for various vendors. Additionally, the report examines challenges the market continues to face and trends to expect, as well as a competitive analysis of eight top vendors in the SLR industry.

Sample research data from the report is shown in the excerpts below:
Table of Contents (vsi0509_toc.pdf)
One of the overriding goals of SLR is to change the break/fix mentality that many IPT managers have to a mentality of true QoS analytics. This includes having the ability to gain a full-level view of the entire IPT environment, from the network level up to the IT infrastructure and all the way up through applications and user interfaces, as shown in the following excerpt.
