IMTC Releases Software Defined Networking Quality of Experience SpecificationSAN RAMON, Calif. --(Business Wire)-- The International Multimedia Telecommunications Consortium (News - Alert) (IMTC), a non-profit industry association facilitating interoperable, real-time, multimedia telecommunications, announced today the availability of its next generation Software Defined Networking (SDN) Quality of Experience (QoE) specification for public download. The specification describes the shortcomings of traditional QoS mechanisms in Unified Communications (News - Alert) and Collaboration (UC&C) environments and defines an automated Quality of Experience (QoE) service module that uses SDN to dynamically adjust the network to the UC&C application requirements. Most network administrators don't trust QoS markings from applications, and UC&C endpoints mix voice and video traffic with non-real-time traffic on the same network infrastructure, which can result in UC&C QoE degradation and a poor end user experience. Since UC&C traffic is generally encrypted for security and confidentiality reasons, network elements have insufficient visibility into UC&C traffic for proper control over network resources like QoS, path selection and bandwidth reservations without requiring complex and error-prone manual networking provisioning. A comprehensive approach to delivering an optial QoE for UC&C environments requires new mechanisms like those defined in the IMTC's specification, thereby allowing UC&C applications to signal multimedia application requirements to the network via an application programing interface (API). These mechanisms enable automated QoE Services to optimize end user quality, including dynamic QoS marking, dynamic Traffic Engineering (TE) and Admission Control (AC). "IMTC is creating open standards with practical and workable solutions to real-time, multimedia telecommunications QoE issues that bridge the gaps in existing technology," said Anatoli Levine, IMTC president and Director of Product Management for Spirent (News - Alert) Communications. "We are very excited to announce this specification that will help the industry provide end users an optimal quality of experience in emerging UC&C environments." The UC SDN Activity Group focuses on the use of Software Defined Networking as a solution for unified communication system quality of service problems. By allowing UC infrastructure to dynamically interact with the network, we aim to ensure that application-level quality and performance requirements can be met by the underlying network infrastructure. The AG engages in analyzing SDN capabilities, and defining a UC SDN framework, use cases, APIs and certification programs.
