Abstract

Selected processes are associated with sets of specific network addresses, and the associations are stored. When a selected process creates a child process, an association between the child process and the set of network addresses with which the parent process is associated is stored. When a selected process is deleted, the association between the selected process and its set of network addresses is deleted. Each selected process is restricted to network address-based communication via its associated set of network addresses. Certain communication protocol subroutines associated with network address-based communication are intercepted by an interception module. The interception module detects attempts by selected processes to communicate via network addresses. If a selected process attempts to communicate via an unassociated network addresses, the attempted communication is prohibited.

Claims

1. A method performed by a computer system having a processor for efficiently managing communication via a set of specific, multiple network addresses, the method comprising:

associating at least one selected process, executed by the processor, with a set of specific, multiple network addresses;

associating a separate communication channel with each one of the multiple network addresses;

detecting an attempt by a selected process to receive an incoming request to initiate a communication session on one of the communication channels;

identifying a first one of the communication channels that is ready to receive the incoming request; and

allowing reception of the incoming request on the identified communication channel.

2. A computer-readable storage medium storing computer-executable instructions for efficiently managing communication via multiple network addresses, the instructions comprising:

instructions for associating a selected process with a plurality of network addresses;

instructions for associating a separate communication channel with each of the plurality of network addresses;

instructions for detecting an attempt by the selected process to receive an incoming request to initiate a communication session on one of the plurality of communication channels;

instructions for identifying one of the plurality of communication channels that is ready to receive the incoming request; and

instructions for allowing reception of the incoming request on the identified communication channel.

3. A method for efficiently managing communication via a set of specific, multiple network addresses performed by a computer system having a processor, the method comprising:

associating at least one selected process, executed by the processor, with a set of specific, multiple network addresses;

associating a separate communication channel with each one of the multiple network addresses;

identifying a first one of the communication channels that is available for communication; and

allowing communication to proceed via the identified communication channel.

4. A computer-readable storage medium storing computer-executable instructions for efficiently managing communication via multiple network addresses, the instructions comprising:

program code for associating a selected process with a plurality of network addresses;

instructions for associating a separate communication channel with each of the plurality of network addresses;

instructions for identifying one of the plurality of communication channels that is available for communication; and

instructions for allowing communication to proceed via the identified communication channel.

5. A computing system having a processor for efficiently managing communication via multiple network addresses, comprising:

a network address association subsystem executed by the processor that associates a selected process with a plurality of network addresses;

a network address association subsystem that associates a separate communication channel which each of the plurality of network addresses;

a detection subsystem that detects an attempt by the selected process to receive an incoming request to initiate a communication session on one of the plurality of communication channels;

an identification subsystem that identifies one of the plurality of communication channels that is ready to receive the incoming request; and

a receipt permission subsystem that allows reception of the incoming request on the identified communication channel.

6. A computing system having a processor for efficiently managing communication via multiple network addresses, comprising:

a network address association subsystem executed by the processor that associates a selected process with a plurality of network addresses;

a network address association subsystem that associates a separate communication channel with each of the plurality of network addresses;

an identification subsystem that identifies one of the plurality of communication channels that is available for communication; and

a communication permission subsystem that allows communication to proceed via the identified communication channel.
