TCP Engines brings Ustream increased video quality and reduced buffering by licensing TCP Engines' TCP-MAX™ solution for streaming optimization

TCP Engines' congestion management and bandwidth optimization solutions are shown to increase throughput by 50% to 285%.

SANTA CLARA, Calif., May 13, 2014 /PRNewswire-iReach/ -- TCP Engines, the leading supplier of TCP optimization solutions, today announced a partnership with Ustream, Inc., the world's most scalable and social live video platform.  The core of the Ustream Cloud Platform centers on the company's proprietary Ustream Content Delivery Network (UCDN), Ustream Media Server (UMS) and Ustream TCP Congestion Control Algorithm (UTCP).  TCP Engines is at the core of the TCP Congestion Control Algorithm.  TCP Engines congestion control solutions effectively unclog networks, and find more bits to deliver to consumers, increasing the video quality and experience for consumers.

According to Arpad Kun, Director of Network Operations of Ustream, "The TCP Engines solutions help us further differentiate the Ustream platform.  After benchmarking against all known TCP solutions in the market, we found the TCP Engines solution to deliver the greatest benefit for our platform, publishers and users.  TCP Engines delivers over 50% increased throughput over Bic, and over 285% increased throughput than htcp.  Further, by reducing buffers ratios to 1.6% and increasing video quality, we are able to offer a more compelling service."

According to Bob Reid of TCP Engines, "We are excited to work with Arpad and his team at Ustream, as they are pioneers in live streaming video technologies.  And to see TCP Engines run at such a large scale, and in the core of a network that streams worldwide is a great testament to the years of research and development we have dedicated.  We look forward to tuning even more with Arpad's team at Ustream to deliver even better results." 

TCP Engines productized TCP-MAX™ as a congestion management and bandwidth optimization solution that enables any source to achieve close to the theoretical limit of the network speed.  Based on an aggregate of decades of research, TCP-MAX™ not only adjusts for both loss-based and delay-based packet loss & congestion, it dynamically adapts to changing network conditions to deliver the highest possible throughput and responsiveness.  Many other techniques are not "fair" and effectively steal bandwidth from lesser TCP stacks, but TCP-MAX™ has proven to be very "fair" in all network conditions. 

About TCP Engines:

TCP Engines, the leader in congestion management and bandwidth optimization solutions since 2009, actively partners with mobile, CDN, data center, website, and network hardware suppliers to deliver the maximum throughput with the lowest latency.  Patented and deployed throughout the world, TCP Engines' solutions enable the next-generation delivery of applications, data and video.
