Streamcore Files Patents on Intelligent Real-Time Protocol Analysis

April 13, 2011

Streamcore, a leading global provider of visibility and dynamic performance control solutions to manage interactive applications and real-time communications delivery over the WAN, has recently announced that the company has filed for new patents.

Streamcore has patents pending for its advanced audio and video traffic classification technology, which are based on intelligent Real-Time Protocol (RTP) passive analysis and key attributes or signatures extraction. RTP helps to automatically detect the different types of Unified Communications & Collaboration (UCC) traffic, and Streamcore has added advanced Deep Packet Inspection (DPI) technology for UCC in to the mix for best performance for business-critical UCC traffic over the WAN.

In a release, Frederic Hediard, vice president of product strategy at Streamcore said that, “The time of VoIP and videoconferencing traffic classification being done on routers based on VLAN or IP addresses is over. With the advent of Unified Communications, enterprises will need to rely on advanced DPI technologies to apply tailored and business-oriented network policies for an HD videoconference session, an executive one-to-one desktop visual communication, and critical VoIP flows. Streamcore continues to develop innovative technologies to provide the best-of-breed DPI engine for UCC on the market.”

With the increasing use of UCC, there is a high need for maintaining acceptable service levels for UCC especially audio and video communications while adopting UCC. Businesses need to primarily detect and identify the UCC flows on the network, in order to focus on monitoring and to prioritize these flows. UCC convergence has complicated matters as audio and video traffic use dynamic UDP port ranges, and different devices with distinct IP addresses are used for different types of traffic such as a PC for data, an IP phone for audio, or a videoconferencing system for video. This can be solved by leveraging a Unified Communication (UC) client which can be installed on a PC with a softphone and webcam, a UC phone or a tablet. The UC client uses a single IP address to exchange business applications, audio and video traffic.

In other news from December 2010, LaSer Contact, a European customer relations services company, has selected a Streamcore solution to manage the interactive applications and real-time communications on its corporate network. LaSer Contact sourced this solution to optimize the quality of service of its global contact centers.
