Abstract

A method for establishing a full end-to-end functionality chain of collaborating network accessible capabilities within a network centric environment is described. The method includes identifying the network accessible capabilities that are necessary to implement the end-to-end functionality chain, receiving data relating to which capabilities are available at each network node, determining if all necessary capabilities are available based on received responses to the data request, selecting one or more network accessible capability instances for each necessary network accessible capability, and executing the selected capability instances in an order that implements the end-to-end functionality chain.

determining if the network accessible capabilities associated with the first set of data are available based on received responses to the data request;

selecting one or more network accessible capability instances for each network accessible capability associated with the first set of data;

executing the selected network accessible capability instances in an order that implements the end-to-end functionality chain; and

monitoring the one or more network accessible capabilities for a connectivity failure of a first capability instance of the selected network accessible capability instances, wherein a second set of data relating to which necessary network capabilities are available at each network node is received if the connectivity failure of the first capability instance occurs.

2. A method according to claim 1 wherein executing the selected network accessible capability instances comprises causing selected network accessible capability instances to collaborate via a middleware communication framework.

3. A method according to claim 1 wherein executing the selected network accessible capability instances comprises sharing information between the network accessible capabilities to establish references between the network accessible capabilities.

4. A method according to claim 1 wherein identifying the network accessible capabilities comprises one of:

identifying the network accessible capabilities while the network centric environment is operational; and

identifying the network accessible capabilities prior to the network centric environment being operational.

5. A method according to claim 1 wherein the network accessible capabilities are centrally defined and coordinated.

6. A method according to claim 1 wherein selecting one or more network accessible capability instances comprises assigning network accessible capability instances to one or more capability categories, where the capability categories include at least one of:

platform dependent capabilities which are constrained to execute on at least one particular platform;

platform dependent capabilities which execute on one platform but are statically or dynamically allocated to control and interface with a separate platform;

network dependent capabilities that are constrained to execute on a particular platform based on a network connectivity between that particular platform and another platform; and

personnel dependent capabilities that are constrained to execute on behalf of specific system operators on specific platforms with which those operators interact.

7. A method according to claim 1 wherein identifying the network accessible capabilities comprises examining metadata associated with the network accessible capabilities to determine all of:

a unique identifier for each network accessible capability;

at least one associated capability category for each network accessible capability;

at least one communication framework associated with each network accessible capability; and
