Abstract

A physical layer photonic protocol switch (PLPPS) that is protocol independent and switches at the optical signal level. Computing subsystem resources are linked to the PLPPS and are grouped into one or more logical system topologies. If needed, additional computing subsystem resources can be allocated to the logical system topology, during runtime. The PLPPS provides the ability to dynamically allocate computing subsystem resources to specific computing enclaves. The PLPPS manages the configuration of and controls access to the computing subsystem resources. Computing resources can then be assigned to specific logical system topologies and additional computing subsystem resources are able to be shared, added or removed, from other logical system topologies, as needs fluctuate. This physical layer switch architecture creates a dynamic computing infrastructure allowing for the sharing of a single computing subsystem resource amongst two or more logical system topologies.
