  • Patent number: 9923728
    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.

  • Patent number: 9825870
    Abstract: A method is provided in one example and includes receiving a request to initiate a communication flow associated with a subscriber and identifying one or more parameters to be monitored for the communication flow. The method further includes extracting one or more bits from packets associated with the communication flow; the bits are used to determine an operating system associated with the communication flow. A policy decision can be executed for the communication flow based on the operating system associated with the communication flow. In more specific examples, the bits are sent to a next destination in response to a threshold being reached for at least one of the parameters. The parameters can be associated a volume parameter or a time parameter. The policy decision could include blocking traffic associated with the subscriber, initiating billing, redirecting the communication, managing a quality of service level for the communication flow, etc.

  • Patent number: 9246837
    Abstract: A method is provided in one example embodiment and includes creating at a network element an entry designating an out of order (“OOO”) sequence number range associated with a flow and receiving at the network element a packet associated with the flow, wherein the packet corresponds to a first sequence number range, wherein the first sequence number range falls within the OOO sequence number range designated in the entry. The method may further include updating the entry to remove sequence numbers comprising the first sequence number range from the OOO sequence number range and forwarding the packet without awaiting receipt of any other packets associated with the flow.

  • Patent number: 9148380
    Abstract: A method is provided in one example and includes receiving a plurality of packets associated with a flow; parsing the plurality of packets associated with the flow; executing a first quality of service decision such that a first set of packets within the plurality of packets are not forwarded to their intended destination; receiving a second set of packets, which reflects a retransmission of at least a portion of the first set of packets; executing a second quality of service decision such that the second set of packets is forwarded to their intended destination; and billing the second set of packets in response to forwarding the second set of packets. In more detailed embodiments, the method includes accessing a table in which entries are provided for particular sequence number ranges for the first set of packets.

  • Patent number: 8792495
    Abstract: A method is provided in one example and includes receiving a request packet associated with a flow; designating an out of order sequence number range associated with the flow; creating an entry that designates the out of order sequence number range; receiving a subsequent packet that includes a particular sequence number range; referencing the out of order sequence number range; resolving a portion of the entry corresponding to the particular sequence number range for the subsequent packet; and forwarding the subsequent packet. In other embodiments, the request packet includes a content length field indicating the out of order sequence number range associated with the flow. Creating the entry can include creating a segment within a queue for the out of order sequence number range, which reflects expected sequence numbers for packets associated with the flow.

  • Publication number: 20030023877
    Abstract: A system and method of managing transmission loads in a data communication network implement a plurality of data processing modules, such as computer servers, each of which may be responsible for a limited range of data processing tasks. A load manager may distribute incoming data packets in accordance with the particular network transaction with which the data packets are associated as well as the present load at each of the plurality of data processing modules. A dedicated load manager, such as a computer server, may execute a hash function to direct incoming, data traffic and to allocate system resources.
