Abstract: A process capable of distributing data is configured to receive a stream of data formatted under a wireless data communication protocol such as Universal Mobile Telecommunications System (“UMTS”) or Long Term Evolution (“LTE”). After identifying the portion of the IP data from the stream of data in accordance with a predefined IP data identifier, the process separates the IP data from the stream of data. Upon reformatting the IP data into one or more IP packets, the IP packet(s) bypasses at least a portion of circuit network and move directly to an Internet router.

Abstract: A method for switching packets in a communication network is provided. The method includes dividing a data stream into at least two sub-streams in a first application card received in a first application card slot of a packet switch. A first sub-stream is sent through a first application port associated with the first application card slot to a first switch port associated with a switch port slot of the packet switch. The switch port slot is operable to receive a switch card for the packet switch. A second sub-stream is sent through a second application port associated with the first application card slot to a second switch port associated with the switch port slot.

Abstract: An apparatus for use in a first packet switching device that transmits outgoing data packets to a second packet switching device over N heterogeneous data links. The first packet switching device comprises N packet queues for storing outgoing data packets. The apparatus selects one of the N heterogeneous data links to transmit a first outgoing data packet. The apparatus comprises a controller that calculates a packet delay value for each one of a subset of S of the N heterogeneous data links. The packet delay (PD) value for each data link is determined as a function of i) a propagation delay (D) of the data link; ii) a packet size (PS) of the first outgoing data packet; iii) a queue size (QS) of a packet queue associated with the data link; and iv) a bandwidth (BW) of the data link.

Abstract: An apparatus and method for using an error correcting code to achieve data compression in a data communication network is disclosed. Data compression is achieved by performing an error correction encoding operation on input data. Data compression is further achieved by providing, for transmission across a communication channel, compressed data that is representative of the input data. The compressed data preferably includes error correction information produced by the error correction encoding operation. The compressed data requires less transmission channel capacity than does the input data.

Abstract: A method for switching frames in a switching system is provided. The method includes receiving a first stripe set for a first port at a second port. The first stripe set is stored in a particular location in a queue of the second port. A determination is made regarding whether a first full flag associated with the first port has been set. If the first full flag has not been set, the first full flag is set and the particular location in the queue of the second port is provided to the first port.

Breaks in the alternating sequence identify failed links and cause all traffic to be sent via the remaining good link. Support for multiple IOP modules and switch fabrics also is provided.
