Abstract

Multiple listening sockets are supported on a single local address port through use of a duplication flag. Each of the listening sockets has a logical queue. Upon creation of a listening socket, the socket is classified and assigned an identifier. As data packets are received, a manager is provided to map the data packets to one of the listening sockets based upon the assigned classification. Receipt of the data packet by an appropriately classified socket, results in the data packet being placed on the logical queue of the assigned listening socket.

Claims

1. A method for managing inbound connection requests comprising:

creating at least two listening sockets on a single local address port and assigning a classification to each created listening socket, with each listening socket having a single logical queue;

categorizing a received inbound connection request; and

mapping said inbound request to said queue of one of said listening sockets based on said categorization of said request and said assigned classification of said sockets.

2. The method of claim 1, wherein the step of mapping an inbound request to said queue includes allowing static resource allocation categorization.

3. The method of claim 1, wherein the step of creating at least two listening sockets on a single local address port includes setting a flag on a first socket to support creation of multiple sockets on a single local address port.

4. The method of claim 1, wherein the step of creating at least two listening sockets on a single address port includes placing only an identifier of a first listening socket in a hash table and linking each secondary listening socket to said first listening socket.

5. The method of claim 1, wherein the step of creating at least two listening sockets on a single address port includes placing identifiers of each of said listening sockets in a hash table.

6. The method of claim 1, wherein the step of mapping an inbound request to said queue of one of said listening sockets includes assigning a classification of said inbound request based upon content of said request.

7. A computer system comprising:

at least two listening sockets on a single local address port, with each listening socket having an assigned classification and a single accept queue;

a category assigned to an inbound request packet; and

a manager adapted to map said inbound request packet to said queue of one of said listening sockets based on said assigned category of said packet and said assigned classification of each socket.

8. The system of claim 7, wherein said manager provides static resource allocation categorization.

9. The system of claim 7, wherein said listening sockets on said local address port includes a flag set on a first socket to support creation of multiple sockets.

10. The system of claim 7, further comprising a hash list adapted to store an identifier of each created socket.

11. The system of claim 7, wherein said manager is adapted to identify an inbound request prior to placement of said request in said queue.

12. The system of claim 11, further comprising said manager adapted to match said identified inbound request with said classification.

13. An article comprising:

a computer-readable signal-bearing medium;

means in the medium for creating at least two listening sockets on a single local address port and for assigning a classification to each created listening socket, with each listening socket having a single accept queue;

means in the medium for assigning a category to an inbound request packet; and

means in the medium for mapping an inbound request to said queue of one of said listening sockets based on said assigned category of said inbound request packet and said assigned classification of each listening socket.

14. The article of claim 13, wherein said means for mapping an inbound request to said queue includes allowing static resource allocation categorization.

15. The article of claim 13, wherein said means for creating at least listening sockets on a single local address port includes setting a flag on a first socket to support multiple sockets.

16. The article of claim 13, wherein said means for creating at least two listening sockets on a single address port includes adding each socket identifier to a hash list.

17. The article of claim 13, wherein said means for mapping an inbound request to said queue of said listening sockets includes identifying said inbound request.

18. The article of claim 17, further comprising means in the medium for matching said identified inbound request with said classification.
