Abstract
Abstract The present invention is directed to a system, method and software product for balancing resource services are always available to match the desired work to be done through the use of “sticky services.”. Sticky services are defined as services that you know you want to have available as resources and as such they need to be present in the environment of cooperative applications; it may be that you want these always present or it may be that you want them present whenever certain conditions occur (see NewWave policy service). The general assumption of distributed systems is to not count on the environment you want being present, or put another way assume failure will occur. Therefore distributed environments like Jini assume all services are transient and will be garbage collected when not in active use. For the inside out approach to work, a mechanism should exist that, when desired, counters the transit design assumptions. This implies that two things are needed: (1) a mechanism for providing services as needed; (2) a mechanism for insuring the correct balance of resource services are always available to match the desired work to be done.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
152 words
A method, comprising: receiving a first service request that specifies a service of multiple distributed services to be deployed; creating an affiliation between the specified service and a first management agent that will supervise the specified service; selecting a first host among a plurality of distributed hosts; deploying the first management agent at the selected first host; identifying an expiration of the created affiliation between the specified service and the first management agent, wherein identifying the expiration of the created affiliation comprises: identifying a failure of the first management agent to renew the affiliation; selecting a second host among the plurality of distributed hosts; deploying a replacement management agent to the selected second host that will supervise the specified service; receiving an affiliation renewal indication from the first management agent; and sending an affiliation renewal exception to the first management agent indicating that it has been replaced by the replacement management agent.
Claim 2
Independent Claim
152 words
A method, comprising: receiving a first service request that specifies a service of multiple distributed services to be deployed; creating an affiliation between the specified service and a first management agent that will supervise the specified service; selecting a first host among a plurality of distributed hosts; deploying the first management agent at the selected first host; identifying an expiration of the created affiliation between the specified service and the first management agent, wherein identifying the expiration of the created affiliation comprises: identifying a failure of the first management agent to renew the affiliation; selecting a second host among the plurality of distributed hosts; deploying a replacement management agent to the selected second host that will supervise the specified service; receiving an affiliation renewal indication from the first management agent; and sending an affiliation renewal exception to the first management agent indicating that it has been replaced by the replacement management agent.
Claim 3
Dependent Claim
22 words
The method of claim 1 , further comprising: creating a record in response to the service request the record describing the service.
Claim 4
Dependent Claim
16 words
The method of claim 2 , wherein the record comprises information required to create the service.
Claim 5
Dependent Claim
23 words
The method of claim 3 , wherein the information comprises a uniform resource locator (URL) of class codebase, class name and initialization information.
Claim 6
Dependent Claim
15 words
The method of claim 2 , wherein the record further specifies the first management agent.
Claim 7
Dependent Claim
65 words
The method of claim 1 , wherein selecting the first host among the plurality of distributed hosts comprises: publishing a solicitation to the plurality of distributed hosts; receiving volunteer responses from a subset of the plurality of distributed hosts in response to the published solicitation; and selecting the first host from among the subset of the plurality of distributed hosts by applying a selection policy.
Claim 8
Dependent Claim
21 words
The method of claim 6 , wherein the selection policy comprises one of a random choice or a round-robin selection policy.
Claim 9
Dependent Claim

Claim 11
Independent Claim
93 words
A method, comprising: deploying management agents at distributed locations in a network; affiliating each of the management agents with a service of multiple distributed services; assessing a health, at each of the management agents, of a corresponding affiliated service of the multiple distributed services; storing each affiliation of a management agent and a service of the multiple distributed services as a lease entry in a database; and storing each lease entry in a priority queue based on a time associated with a creation of the affiliation between the management agent and the service.
Claim 12
Independent Claim
93 words
A method, comprising: deploying management agents at distributed locations in a network; affiliating each of the management agents with a service of multiple distributed services; assessing a health, at each of the management agents, of a corresponding affiliated service of the multiple distributed services; storing each affiliation of a management agent and a service of the multiple distributed services as a lease entry in a database; and storing each lease entry in a priority queue based on a time associated with a creation of the affiliation between the management agent and the service.
