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.

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.

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.

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.

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.

A router for transmitting data packets to and receiving data packets from N interfacing peripheral devices. The router comprises a first packet processor that receives a first data packet from a physical medium device (PMD) module coupled to one of the N interfacing peripheral device and determines if a format of the first data packet is one of IPv4, IPv6 and MPLS. The first packet processor determines a destination device of the first data packet by looking up the destination device in a unified forwarding table containing destination devices for data packets in IPv4 format, IPv6 format, and MPLS format.

A router for interconnecting N interfacing peripheral devices. The router comprises: i) a first switch fabric; ii) a second switch fabric; and iii) a plurality of routing nodes coupled to the first and second switch fabrics. Each of the routing nodes comprises an input-output processing (IOP) module for forwarding received data packets to other ones of the IOP modules via the first and second switch fabrics. A first one of the IOP modules forwards received data packets directed to a second one of the IOP modules by alternating between the first and second switch fabrics for each sequential data packet directed to the second IOP module. 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.

Software inverse multiplexing within an Asynchronous Transfer Mode (ATM) communication network is provided by a first ATM switch receiving a stream of ATM cells over a high bandwidth communication link. A Segmentation and Re-assembly (SAR) module associated with the first ATM switch thereafter reassembles the received ATM cells into corresponding user packets. Control data identifying the sequence of assembled user packets are added to each user packet and de-assembled into corresponding ATM cells. The de-assembled ATM cells are then communicated over a plurality of low bandwidth communication links to a second ATM switch. The second ATM switch receives the transmitted ATM cells over said low bandwidth communications links. A SAR module associated with the second ATM switch thereafter reassembles the received ATM cells into corresponding user packets. Utilizing the enclosed control data, received user packets are re-synchronized into their original sequence. The control data are then removed and the user packets are de-assembled back into corresponding ATM cells. The de-assembled ATM cells are then communicated over an outgoing high bandwidth communication link.
