1. An architecture for implementing a nodal complex that supports multiple quality of service (QoS) realms, comprising: a first set of extended enterprise service bus (EESB) rules for supporting nodes operating in a sub-second QoS realm; a second set of EESB rules for supporting nodes operating in a millisecond QoS realm; a third set of EESB rules for supporting nodes operating in a microsecond QoS realm; and a fourth set of EESB rules for communicating data and sharing compute capability amongst nodes operating in different QoS realms by using an inter-bus communication pattern that is super-ordinate to the first, second and third sets of EESB rules.
