Abstract: A virtual reality system including a head mounted display (HMD), a server, and a beam steering apparatus utilizes optical data transmission from the server to the HMD. The data rates/bandwidths provided by optical data transmission allow the amount of compression needed for data transfer (and the latency associated with compression) to the HMD to be reduced. The efficient offloading of processing tasks from the HMD to the server, reduces HMD power consumption, and enables the delivery of video having high resolution, framerate, and quality. As the user of the HMD moves, and the pose (position and orientation) of the HMD changes, the pose is provided to the server and beam steering apparatus. Based on the pose, the server renders image frames for transmission to the HMD and the beam steering apparatus directs an optical beam to the HMD to enable transmission of the image frames from the server to the HMD.

Abstract: Techniques and architectures may be used to generate data center network topologies that use less reliable and less expensive links mixed with links of higher reliability. Such topologies may be categorized into reliability classes, where each class corresponds to a bound(s) on reliability of paths that include the links. A topology class may be selected for use by an application based, at least in part, on the degree of reliability demanded by the application.

Abstract: Aspects and implementations of the present disclosure are directed to a network device storing an address table. Each of the address table entries is assigned to a respective provisioned index value and an instance of a distributed service. The device is configured to add a new service instance to the address table by obtaining an assignable index value for the new service instance, identifying an assigned index value that is a companion index value to the obtained index value, dividing a packet source address set associated with the companion index value into first and second address subsets, and assigning the first address subset to the service instance entry in the address table associated with the assigned companion index value and the second address subset to an entry in the address table associated with the obtained index value and the newly added service instance.

Abstract: This disclosure relates to video segment identification and organization based on dynamic characterizations. A media component streams media content to a user device at a rate based at least in part on a congestion window size, and a trickle component determines the congestion window size based at least in part on a set of limiting criteria. The set of limiting criteria can include but is not limited to a queuing delay, a target transmission rate, and/or a packet loss compensation factor.
