The Science Behind the Services
High quality and cost-effective video distribution over the Internet has long been an overarching vision and a grand challenge for the communication and media industry. Conviva brings together the disciplines of high-scale, parallel compute processing and real-time algorithmic inference with policy management to optimize both the quality and cost of online video. In addition, content owners have the instant audience insights they require for success.
For the last two decades, Conviva researchers have solved some of hardest technical problems, and pioneered key architectural innovations in fulfilling the promise of Internet video.
Quality of Service (QoS) Algorithms and Protocols 12,13
As part of his Ph.D. dissertation research, Dr. Hui Zhang, co-founder and chief scientist, co-designed and co-implemented the Tenet Protocol Suite, the first protocol suite that guarantees real-time performance in a packet-switching internet work.
Scalable Management of Distributed States 12
The award-winning Ph.D. dissertation of Dr. Ion Stoica, co-founder and chief technical officer, pioneered the first scalable architecture to manage QoS states in a distributed networking environment.
Overlay Multicast and Scalable Streaming Protocols 5,6,11
Dr. Zhang’s End System Multicast (ESM) research group at Carnegie Mellon pioneered the overlay multicast architecture and techniques to support scalable Internet video streaming. Jibin Zhan and Aditya Ganjam, two Conviva team members, led the development and deployment of the first Internet peer-to-peer live streaming system.
Scalable, Resilient, and Intelligent Network Control Software 4,5
Both Conviva co-founders have worked on new network architectures which enable direct control on routing data traffic, support network-level objectives, and provide network-wide visibility.
Cloud Computing 1,2
Dr. Stoica’s research group at the University of California at Berkeley has done pioneering research on enabling multiple frameworks, such as Hadoop and Hypertable, to share seamlessly the same cluster, and improve the performance of those frameworks.
Distributed Hash Tables 7
Dr. Stoica has done pioneering work on distributed hash tables, a key technology which has been successfully used to provide large-scale distributed storage systems, and peer-to-peer lookup protocols.
Practical Secure Software 8,13
Dr. George Necula, a Conviva team member and a professor of Computer Science at the University of California at Berkeley, invented self-certifying code, a key capability of enabling practical secure software over the Internet.
Automatic Network Diagnosis 3
Dr. Ningning Hu, a Conviva team member, developed the Internet’s most powerful performance and diagnosis software.
