The REsilient LOosely Coupled (ReLoC) system and method implement a session-state management architecture for cloud computing that uses loosely-coupled services and platform agnostic scalable messaging technology to propagate and save session states. Maintaining the state of applications and user sessions is difficult in large scale web-based software systems, particularly in the context of cloud computing (e.g., platform as a service (PaaS) vendors, do not explicitly support state management infrastructure, such as clustering). In a PaaS environment, a user has little or no access and control over the server platform and session management layer. The platform tiers are generally loosely coupled and service-oriented, which make traditional session-state management techniques non-usable. The ReLoC system and method provides a high level of tolerance to failures of the platform tiers without corresponding disruptions in user sessions. In the context of PaaS Clouds, the ReLoC system provides greater scalability compared to traditional clustering environments.

US09635077B2 Low latency live video streaming
Techniques are disclosed for low latency live video streaming. A client can be configured to send a single HTTP request for live video streaming to a server.

The HTTP 2.0 protocol may be used for pushing the video from the server to the client. This technique eliminates the request explosion problem when small segments are used. Further, the number of segments pushed with each request can be varied, which is to facilitate adaptive bitrate switching.
