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.

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.
