Abstract: A content delivery network (CDN) includes a plurality of CDN components including at least one CDN rendezvous mechanism and at least one control core. The CDN components are controlled by control core data from the at least one control core. Some CDN components obtain CDN resources including control core data from at least some other CDN components. The CDN components use the CDN rendezvous mechanism to select one or more CDN components from which to obtain CDN resources.

Abstract: A computer-implemented method obtains a plurality of image files, each corresponding to an image in a video stream and builds a common file from a contiguous grouping of the plurality of image files. The video stream has a plurality of contiguous video segments, each having a first video frame, and the plurality of image files correspond to the plurality of first video frames of the plurality of video segments. The plurality of video segments are of approximately equal duration.

Abstract: A method includes monitoring the operational status of at least some name servers in a name server network. Based on the monitoring, when an error or anomalous condition is detected at a particular name server, creating a policy to indicate the status of the particular name server. The policy is taken into account when resolving hostnames using the name server network.

Abstract: A device is operable in a content delivery network (CDN). The device has a cache server mechanism constructed and adapted to: upon joining the CDN, obtain global configuration data from a control core of the CDN; and, having joined the CDN, obtain updated global configuration data, if needed; and obtain customer configuration information associated with at least one customer of the CDN. The device serves a particular resource associated with a particular customer of the CDN in accordance with (i) the global configuration data, and (ii) customer configuration information obtained in and associated with the particular customer.
