Telchemy develops software probes and management applications that enable service providers and major enterprises to efficiently manage the quality of Data, Voice, Video and other real-time multimedia services in conventional and virtualized networks. Telchemy pioneered the development of QoE measurement algorithms for VoIP and IP Video, led the development of key reporting protocols used within the industry and is positioned to take a leading position in the emerging software defined and virtualized network.
Telchemy's software products provide real-time visibility of service quality, estimates of user-perceived QoS, and detailed analysis of the root cause of quality degradation for VoIP calls and video sessions in both test and production environments. Our software technology can be integrated by equipment manufacturers into a wide range of products ranging from consumer electronics devices to large telecom systems, monitoring every call and detecting problems in real time. Our products support collection and analysis of real-time call quality data, providing easy integration with management systems and other network and call control systems. We have over 20 granted patents related to the performance management of real time services and have a number of additional applications within the US and European patent offices.

Telchemy was founded in 1999 and is based in Duluth, Georgia.
Telchemy's mission is to be the leading provider of software based performance management technology for new generation IP-based voice and video services.
Telchemy's technology enables service providers, major enterprises and government organizations to efficiently deploy and use IP-based voice and video services. Our distributed software products provide cost-effective real-time performance monitoring and management of voice and video services, software defined and virtualized networks, allowing problems to be quickly identified and resolved and allowing more voice and video traffic to be supported, maximizing service revenues and minimizing operating costs. We are guided by our belief that future networks will become self-healing and self-managing.
Telchemy, Incorporated was founded on August 12th, 1999 by Dr. Alan Clark. Dr Clark has been actively involved in Quality of Service, network performance, packet voice and network management since working at British Telecom in the mid-1980's. He managed research work on Voice over ATM, Voice over Frame Relay, QoS Management, Broadband Services Management and led the team that developed the architecture for British Telecom's next generation management platform.
The first product concept - VQmon® - was developed in early 2000, as a result of an identified need to monitor the quality of live Voice over IP calls. As part of Alan's PhD research related to the performance of network protocols over burst error channels, he knew that IP networks would tend to exhibit bursty packet loss. This raised the question of, how would people react to calls with time-varying quality? Alan combined an efficient method of measuring how lost packets were distributedin time on a Voice over IP call with a perceptual model that reflected the human element, and called the resulting algorithm "VQmon".
Early potential customers were enthusiastic (three offered to invest in the new startup!) and Telchemy started to gain some momentum. Telchemy moved into its first office in Suwanee, GA in January 2001 and in May 2006 moved to a new larger office in Duluth, GA.
Telchemy introduced the first release of VQmon in May 2001, signed first customers in July 2001, and by December 2013 had sold 150 million units of VQmon.
Telchemy's Founder and CEO, Dr. Alan Clark, has over 35 years of industry experience, and 25 years of senior management experience, with companies such as British Telecom, where he was a system architect, Dowty Communications and Hayes. He started his career working in finance, and then returned to college to study engineering, data communications and information theory. His PhD work focused on the development of a high performance data compression algorithm (later adopted by ITU as V.42bis) and performance modeling of data communications protocols over channels with time varying impairments.
Alan has extensive experience in networking, packet voice communications, network management, distributed systems and quality of service/experience. He founded Telchemy in 1999 to pioneer a new distributed approach to application performance management using agent technology integrated directly into the network and connected endpoints. Telchemy's first product, VQmon has been deployed in over 200 million devices and systems and is the most widely used technology for voice and video analytics.
Alan has over 20 granted patents and has played a leading role in performance management standards development in ATIS, ETSI, IETF and ITU. He is an author of multiple IETF RFCs including RFC 3611 , RFC 6035, RFC 6776, RFC 6798, RFC 6843, RFC 6958, RFC 7002, RFC 7003, RFC 7005, RFC 7266, RFC 7294 and RFC 8015, as well as a number of ITU Recommendations. Alan championed the need for a more comprehensive defintion of performance metrics within IETF, which led to the development of RFC 6390 (Guidelines for the definition of metrics) and the establishment of the Performance Metrics Directorate.
Telchemy has a number of granted patents and pending patent applications related to our technology. We do enforce these patents and license them either as patents or in conjunction with the licensing of our software.
