Abstract

The invention provides a communication system for accessing system services on a network of information handling devices including a server running on a host computer adapted to listen at a predefined port for requests for connection to service access agents; where the requests come from a client application; wherein the server is adapted to determine how to start the access agent for service as specified in the request; wherein the server is adapted to start the access agent with a dynamically assigned socket; and, wherein the client is notified by acknowledgment of the request, the acknowledgment including identification of the assigned socket to communicate with the requested access agent; the dynamically assigned socket being selected by system services from sockets available on the host computer on which the server is running; the access agent being adapted to access a requested service.

said access agent being adapted to access a requested service that is already running.

2. The system of claim 1 wherein said network is a tcp/ip network wherein said child server is adapted to perform a security check on said request before requesting access;

and in which said child server determines how to start said access agent by referring to a local database; and

,

wherein said access agent is adapted to exchange information for the requested service with said client.

3. The system of claim 2 wherein said requested service can include further services and other programs.

4. The system of claim 2 wherein said request comprises:

a host name of the computer that the server being contacted is on;

an application type identifying the class of service requested;

at least one application ID which provides the instance of the service requested.

5. A communication system for accessing system services on a data communication network of computing devices comprising:

server means running on a host computer adapted to listen at a well known port for requests for connection to transient service access agents which are started by said server after receiving a request;

where said requests come from a client application on the same or another computer;

and when receiving such a request generates a child server to handle said request;

wherein said child server is adapted to determine how to start said access agent for service as specified in said request;

wherein said child server is adapted to start said access agent with a dynamically assigned socket; and

,

wherein said client is notified by acknowledgment of said request, said acknowledgment including identification of said assigned socket to communicate with said requested access agent;

said dynamically assigned socket being selected by system services from sockets available on said host computer on which said server is running;

said access agent being adapted to access a requested service wherein said access agent is adapted to receive information for the requested service from said client; and

,

is adapted to start a connection to a service that is not running, and;

to connect to a service that is already running.

6. A computer program product comprising:

a computer usable medium having computer readable program code means embodied therein for operating a communication system for accessing system services on a network of information handling devices comprising;

program code for causing;

server means running on a host computer to listen at a predefined port for requests from a client application for connection to service access agents;

wherein said server is adapted to determine how to start said access agent for service as specified in said request;

wherein said server is adapted to start said access agent with a dynamically assigned socket; and

,

including code means wherein said client is notified by acknowledgment of said request, said acknowledgment including identification of said assigned socket to communicate with said requested access agent;

said dynamically assigned socket being selected by system services from sockets available on said host computer on which said server is running;

said access agent being adapted to access a requested service whether said service is running or not running.

7. A computer program product comprising:

a computer usable medium having program code means embodied therein for causing the establishment of a communication system for accessing system services on a data communication network of computing devices comprising;

program code means in said computer program product to effect;

server means running on a host computer to listen at a well known port for requests for connection to transient service access agents which are started by said server after receiving a request;

where said requests come from a client application on the same or another computer;

and when receiving such a request generates a child server to handle said request;

wherein said child server is adapted to determine how to start said access agent for service as specified in said request;

wherein said child server is adapted to start said access agent with a dynamically assigned socket; and

,

wherein said client is notified by acknowledgment of said request, said acknowledgment including identification of said assigned socket to communicate with said requested access agent;

said dynamically assigned socket being selected by system services from sockets available on said host computer on which said server is running;

said access agent being adapted to access a requested service wherein said access agent is adapted to receive information for the requested service from said client; and

,

is adapted to start a connection to a service that is not running; and

,

to connect to a service that is already running.

8. The system of claim 7 wherein said network is a tcp/ip network wherein said child server is adapted to perform a security check on said request before requesting access;

and in which said child server determines how to start said access agent by referring to a local database; and

,

wherein said access agent is adapted to exchange information for the requested service with said client.

9. The system of claim 8 wherein said requested service can include further services and other programs.

10. The system of claim 8 wherein said request comprises:

a host name of the computer that the server being contacted is on;

an application type identifying the class of service requested;

at least one application ID which provides the instance of the service requested.

11. A method for operating a communication system for accessing system services on a network of information handling devices comprising:
