Abstract

An architecture and method for implementing a nodal complex (NC) supporting multiple quality of service (QoS) realms is provided. The disclosed architecture includes: 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.

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.

2. The architecture of claim 1, wherein the first, second and third sets of EESB rules each define a set of acceptable communication protocols for an associated QoS realm.

3. The architecture of claim 1, wherein each node participating in the nodal complex includes an EESB.

4. The architecture of claim 3, wherein nodes participating in the nodal complex are configured to access services from subnodes in accordance with the first, second and third sets of EESB rules.

5. The architecture of claim 1, wherein a plurality of nodes in a same QoS realm can be aggregated to provide an aggregated service over the nodal complex.

6. The architecture of claim 1, wherein a first node operating in a first QoS realm can access services from a second node operating in a second QoS realm.

7. The architecture of claim 1, wherein the nodal complex comprises a military warfare network that includes a plurality of platforms, wherein each platform includes nodes operating in different QoS realms.

8. The architecture of claim 1, wherein:

the EESB rules for supporting nodes operating in a microsecond QoS realm are stricter and provide a higher QoS relative to the EESB rules for supporting nodes operating in a millisecond QoS realm; and

the EESB rules for supporting nodes operating in a sub-second QoS realm are more flexible and provide a lower QoS relative to the EESB rules for supporting nodes operating in a millisecond QoS realm.

9. A method for implementing a nodal complex (NC) having an architecture that supports multiple quality of service (QoS) realms, comprising:

providing a first set of extended enterprise service bus (EESB) rules for supporting nodes operating in a sub-second QoS realm;

providing a second set of EESB rules for supporting nodes operating in a millisecond QoS realm;

providing a third set of EESB rules for supporting nodes operating in a microsecond QoS realm; and

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.

13. The method of claim 9, comprising the further step of aggregating nodes in a same QoS realm to provide an aggregated service over the nodal complex.

14. The method of claim 9, comprising the step of having a first node operating in a first QoS realm access services from a second node operating in a second QoS realm.

15. The method of claim 9, wherein the nodal complex comprises a military warfare network that includes a plurality of platforms, wherein each platform includes nodes operating in different QoS realms.

16. The method of claim 9, wherein:

the EESB rules for supporting nodes operating in a microsecond QoS realm are stricter and provide a higher QoS relative to the EESB rules for supporting nodes operating in a millisecond QoS realm; and

the EESB rules for supporting nodes operating in a sub-second QoS realm are more flexible and provide a lower QoS relative to the EESB rules for supporting nodes operating in a millisecond QoS realm.
