Abstract

In one embodiment, a method includes receiving one or more packets of a communication session from one or more interfaces, such that the interface is a subscriber interface or a network interface. The method further includes associating the communication session to an end user with a source Internet Protocol (IP) address of the packet if the packet is received from the subscriber interface or to an end user with a destination IP address of the packet if the packet is received from the network interface.

First claim

What is claimed is:

1. An apparatus, comprising:
a plurality of processors;
a flow manager element communicatively coupled to the plurality of processors and operable to:
receive a first packet of a communication session from one or more interfaces, the first packet being part of a peer-to-peer transaction between a first end user and a second end user;
determine whether the first packet is received from a subscriber interface or a network interface;
associate the communication session to the first end user with a source Internet Protocol (IP) address of the packet when the packet is received from the subscriber interface;
determine a processor from the plurality of processors to forward the received first packet of the communication session based on the associated source IP address;
receive the first packet of the communication session from a network virtual LAN, the first packet being forwarded from a router;
in response to receiving the first packet from the network virtual LAN, associate the communication session to the second end user with a destination IP address;
obtain subscriber information of the first end user and the second end user by searching an external database using the associated source IP address or associated destination IP address;
create a first session object associated with the subscriber information of the first end user, wherein the first session object associated with the subscriber information of the first end user resides on the determined processor;
associate the subscriber information of the first end user with the determined processor;
create a second session object associated with the subscriber information of the second end user;
process billing associated with the first session object and the second session object; and
forward the received first packet of the communication session to the detelmined processor.

2. The apparatus of claim 1 , wherein the flow manager element further operable to determine a routing configuration to forward the received first packet based on whether the first packet is received from the subscriber interface or the network interface.

3. The apparatus of claim 1 , wherein processing billing associated with the first session object and second session object further comprises:
determining type and quantity of received information associated with the received first packet; and
processing billing according to the determined type and quantity of received information associated with the received first packet.

4. The apparatus of claim 1 , wherein obtaining subscriber information by searching an external database further comprises making a single query to the external database to identify the subscriber information.

5. The apparatus of claim 4 , wherein the external database is a known user table included in a client services packet gateway, the known user table operable to store an IP address associated with the first end user.

6. The apparatus of claim 1 , wherein the subscriber interface communicates with a first virtual LAN configured as a subscriber virtual LAN and the network interface communicates with a second virtual LAN configured as a network virtual LAN.

7. A method, comprising:
receiving a first packet of a communication session from one or more interfaces, the first packet being part of a peer-to-peer transaction between a first end user and a second end user;
determining whether the first packet is received from a subscriber interface or a network interface;
associating the communication session to the first end user with a source Internet Protocol (IP) address of the packet when the packet is received from the subscriber interface;
determining a processor from a plurality of processors to forward the received first packet of the communication session based on the associated source IP address;
receiving the first packet of the communication session from a network virtual LAN, the first packet being forwarded from a router;
in response to receiving the first packet from the network virtual LAN, associating the communication session to the second end user with a destination IP address;
obtaining subscriber information of the first end user and the second end user by searching an external database using the associated source IP address or associated destination IP address;
creating a first session object associated with the subscriber information of the first end user, wherein the first session object associated with the subscriber information of the first end user resides on the determined processor;
associating the subscriber information of the first end user with the determined processor;
creating a second session object associated with the subscriber information of the second end user;
processing billing associated with the first session object and the second session object; and
forwarding the received first packet of the communication session to the determined processor.

8. The method of claim 7 further comprises determining a routing configuration to forward the received first packet based on whether the first packet is received from the subscriber interface or the network interface.

9. The method of claim 7 , wherein processing billing associated with the first session object and second session object further comprises:
determining type and quantity of received information associated with the received first packet; and
processing billing according to the determined type and quantity of received information associated with the received first packet.

10. The method of claim 7 , wherein obtaining subscriber information by searching an external database further comprises making a single query to the external database to identify the subscriber information.

11. The method of claim 10 , wherein:
the external database is a known user table included in a client services packet gateway, the known user table operable to store an IP address associated with the first end user.

12. The method of claim 7 , wherein the subscriber interface communicates with a first virtual LAN configured as a subscriber virtual LAN and the network interface communicates with a second virtual LAN configured as a network virtual LAN.

13. A non-transitory computer-readable storage medium encoded with computer-executable instructions, the computer-executable instructions, when executed, operable to cause one or more processors to:
receive a first packet of a communication session from one or more interfaces, the first packet being part of a peer-to-peer transaction between a first end user and a second end user;
determine whether the first packet is received from a subscriber interface or a network interface;
associate the communication session to the first end user with a source Internet Protocol (IP) address of the packet when the packet is received from the subscriber interface;
determine a processor from a plurality of processors in a client service packet gateway to forward the received first packet of the communication session based on the associated source IP address;
receive the first packet of the communication session from a network virtual LAN, the first packet being forwarded from a router;
in response to receiving the first packet from the network virtual LAN, associate the communication session to the second end user with a destination IP address;
obtain subscriber information of the first end user and the second end user by searching an external database using the associated source IP address or associated destination IP address;
create a first session object associated with the subscriber information of the first end user, wherein the first session objec
