Abstract: A rendering processor assigns varying logical pixel dimensions to regions of an image frame and rendering pixels of the image frame based on the logical pixel dimensions. The rendering processor renders in highest resolution (i.e., with smaller logical pixel dimensions) those areas of the image that are more important (on which the viewer is expected to focus (the “foveal region”), or regions with little-to-no motion), and renders in lower resolution (i.e., with larger logical pixel dimensions) those areas of the image outside the region of interest, or regions that are speedily moving, so that loss of detail in those regions will be less noticeable to the viewer. For regions with less detail or greater magnitude of motion, larger logical pixel dimensions reduce the computational workload without affecting the quality of the displayed graphics as perceived by a user.

Abstract: The reputations of content sources are tracked as running rates of content origination. Information concerning content origination from multiple sources is received and aggregated. The aggregated information is used to calculate running rates of content origination. An initial running rate of content origination can be calculated based on the number of detections of originations from a given source over a period of time. Running rates can be updated based on additional detections from the source since the last update. As incoming electronic content is received from specific sources, the running rates from given sources are used to determine whether to block or allow the incoming content. Reputation characterization percentages can be calculated based on the running rates, and incoming content from a specific source can be blocked if a reputation characterization percentage is above a given threshold.

Abstract: A content-aware flow switch intercepts a client content request in an IP network, and transparently directs the content request to a best-fit server. The best-fit server is chosen based on the type of content requested, the quality of service requirements implied by the content request, the degree of load on available servers, network congestion information, and the proximity of the client to available servers. The flow switch detects client-server flows based on the arrival of TCP SYNs and/or HTTP GETs from the client. The flow switch implicitly deduces the quality of service requirements of a flow based on the content of the flow. The flow switch also provides the functionality of multiple physical web servers on a single web server in a way that is transparent to the client, through the use of virtual web hosts and flow pipes.
