Abstract

A method and system for monitoring and managing distributed services in a network. The method involves instantiating a managed peer, a context instance, and a managed service at an edge computing node. The managed peer, the context instance, and the managed service are instrumented and registered with a monitoring server. The method continues with establishing a monitor for the managed peer, the context instance, and the managed service and monitoring during runtime one or more values of the monitor. The method includes modifying the managed peer, the context, and/or the managed service based on the values of the monitors. The method includes caching advertisements of services available from other managed peers in the context, searching the cache for available services or resources, and requesting one or more of the advertised services from managed peers local or remote to the edge computing node.

Claims

1. A method for monitoring and managing distributed services in a network, comprising:

at an edge computing node of the network, instantiating a managed peer, a context, and a managed service;

establishing a monitor for the managed peer, the context, and the managed service;

monitoring a value of the monitor for the managed peer, the context, and the managed service; and

modifying the managed peer, the context, or the managed service based on the value of the corresponding one of the monitors.

2. The method of claim 1, further comprising registering the managed peer, the context, and the managed service with a monitoring server associated with the monitor.

3. The method of claim 2, further comprising prior to the modifying, comparing the monitored values to acceptable bounds defined in a set of policies registered with the monitoring server and only performing the modifying when one of the values is outside the acceptable bounds.

4. The method of claim 1, wherein the monitoring and the modifying are performed during runtime and the modifying comprises altering the configuration of the managed peer, the context, or the managed service.

5. The method of claim 1, wherein the monitoring of the value comprises collecting and analyzing state information for the managed peer, the context, and the managed service.

6. The method of claim 5, wherein the modifying comprises tuning operational parameters.

7. The method of claim 6, further comprising operating the managed peer to cache advertisements of services of other managed peers in a local cache and to search the local cache for available resources.

8. The method of claim 1, further comprising instantiating a service locator and a service loader, operating the service locator to locate a managed service offered by a peer remote to the managed peer, and loading the located managed service on the edge computing node with the service loader.

9. The method of claim 8, wherein the loading operating by the service loader is performed based on a set of policies.

10. The method of claim 1, further comprising instantiating a code server, receiving a provisioning request for the managed service from another managed peer, and delivering code corresponding to the managed service to the requesting managed peer.

11. The method of claim 1, further comprising the managed peer joining a peer group associated with the context and publishing an advertisement for the managed peer in the peer group, wherein the published advertisement is accessible by other managed peers belonging to the peer group.

12. An edge computing node for use in a network utilizing policy-driven service distribution, comprising:

computing resources;

a managed peer adapted for communicating with other managed peers belonging to a context;

a service provided by the managed peer based on the computing resources;

a management registry in which the managed peer and service are registered;

a monitoring mechanism gathering environmental information for the managed peer and the service during runtime and associated with the context;

a set of policies defining configuration and interaction parameters; and

a management mechanism comparing the gathered environmental information to the set of policies and controlling configuration or operation of the managed peer and the service based on the comparison and the set of policies.

13. The node of claim 12, wherein the set of policies are associated with the context.

14. The node of claim 12, wherein the monitoring mechanism comprises listeners gathering state information for the edge computing node during runtime.

15. The node of claim 12, further comprising a service locator for discovering additional computing resources in the network associated with the context and a service loader requesting a service based on the discovered additional computing resources based on the comparison by the management mechanism and loading the requested service on the edge computing node, the loaded services being configured or operated based on the set of policies.

16. The node of claim 12, further comprising a service publisher advertising the service to other nodes in the network associated with the context and a code server distributing code associated with the service to requesting ones of the other nodes based on the set of policies.

17. The node of claim 12, further comprising a context manager registered with the management registry and adapted for managing communications with other managed peers in the networks, the communications comprising advertisements of services offered by the managed peers and changes to the set of policies.

18. A method for the global distribution and self-organization of intelligent, mobile agents, comprising:

instantiating a managed peer;

joining a place instance with the managed peer, the place instance defining an operating environment;

creating an agent implementing and executing domain logic for performing a task, the agent providing at least one mobile behavior;

monitoring the operating environment of the place instance; and

performing the at least one mobile behavior based on the monitored operating environment.

19. The method of claim 18, wherein the at least one mobile behavior comprises migration or replication.

20. The method of claim 18, wherein the agent creating comprises loading the place instance by the managed peer, loading an agent information instance containing information for declaratively defining and describing the agent, using the place instance to instantiate an agent manager, and creating the agent with the agent manager based on the agent information instance.

21. The method of claim 18, wherein the agent performs the task in a manner selected to suit the monitored operating environment.

22. The method of claim 18, wherein the performing of the at least one mobile behavior comprises maintaining a current state of the agent.

23. The method of claim 18, wherein the performing of the at least one mobile behavior comprises transferring agent code and agent state data.

24. The method of claim 18, further comprising performing monitoring, metering, and statistical analysis of the agent, and based on the performing, determining compliance with a set of policies and when determined non-compliant, making adjustments to the agent.

25. The method of claim 18, further comprising exposing the agent as a web service and registering the agent in a web services registry.

26. The method of claim 25, further comprising providing a persistent object containing information defining a WSDL-based definition of the agent as a web service and the agent comprises a WSDL document implementing the WSDL-based definition.

27. The method of claim 25, further comprising serving web application archives (WAR) files based on the agent and locating and requesting another agent comprising a web service in the web services registry.
