Journal ArticleDOI
Performance Evaluation of WebRTC-based Video Conferencing
TL;DR: A thorough performance evaluation of WebRTC both in emulated synthetic network conditions as well as in real wired and wireless networks shows that Web RTC streams have a slightly higher priority than TCP flows when competing with cross traffic.
Proceedings ArticleDOI
Network planning with deep reinforcement learning
TL;DR: NeuroPlan as mentioned in this paper proposes a deep reinforcement learning (RL) approach to solve the network planning problem, which involves multi-step decision making and cost minimization, which can be naturally cast as a deep RL problem.
Proceedings ArticleDOI
Mobile VR on edge cloud: a latency-driven design
TL;DR: The main contribution is in realizing a low latency control loop that streams VR scenes containing only the user's Field of View (FoV) and a latency-adaptive margin area around the FoV that allows the clients to render locally at a high refresh rate to accommodate and compensate for the head movements before the next motion update arrives.
Journal ArticleDOI
Optical multicast system for data center networks.
TL;DR: The design and experimental evaluation of an Optical Multicast System for Data Center Networks is presented, a hardware-software system architecture that uniquely integrates passive optical splitters in a hybrid network architecture for faster and simpler delivery of multicast traffic flows.
Proceedings ArticleDOI
Freedom: Fast Recovery Enhanced VR Delivery Over Mobile Networks
Shu Shi,Varun Gupta,Rittwik Jana +2 more
TL;DR: This paper designs and implements Freedom, a mobile VR system that deliver high quality VR content on today's mobile devices using 4G/LTE cellular networks and is the first system in the world that can support dynamic and live 8K resolution VR content, while adapting to the real-world latency variations experienced in cellular networks.
