Multi-layer configurable timing switch fabric for distributing timing sources to timing consumers

A network-connected processing system, comprising:

• a timing distribution switch having a plurality of input ports configured to receive timing information from a plurality of timing sources and having a plurality of output ports, the timing distribution switch being configured to distribute the timing information to the plurality of output ports based upon pre-configured distribution settings such that the timing information includes information from two or more of the timing sources;
• a plurality of processing blades each having input ports coupled to receive the timing information from the timing distribution switch, having a local timing distribution switch, and having a plurality of user ports, each processing blade being configured to distribute the timing information to the plurality of user ports based upon pre-configured distribution settings for the local timing distribution switch;
• and
• a timing configuration controller configured to apply pre-configured distribution settings to the timing distribution switch and to each of the processing blades;
• wherein the timing distribution switch, the plurality of processing blades, and the timing configuration controller are coupled within a housing for the network-connected processing system.
