Abstract: Embodiments of a network element and method of establishing an internet-protocol communications session between a first device and a second device and generally described herein. In some embodiments, the network element is configured to receive a request from the first device to invite the second device to participate in an IP communications session. The second device may be identified in the request by a network identifier. The network element may relate the network identifier to a mobile IP (MIP) address of the second device and a second IP address. The network element may send an invitation to the MIP address of the second device. The invitation may include a MIP address of the first device and a first IP address. The first device establishes an IP connection for an IP communications session with the second device using the MIP address of the second device and the second IP address.

Abstract: A method is performed by one or more network elements for voice-over-IP (VoIP) communications. The method includes receiving a request from a first mobile device to invite a second mobile device to participate in a VoIP session. The second device may be identified in the request by a network identifier. The network identifier is related to a mobile IP (MIP) address of the second device and a second IP address. An invitation is sent to the MIP address of the second device which may include a MIP address of the first device and a first IP address. A response to the invitation may be received from the second device. The response may be modified to include a first IP header that includes the MIP address of the second device and a second IP header to include the second IP address. The modified response is forwarded to the first device. After receipt of the modified response, the first device is configured to establish an IP connection for VoIP communication with the second device.

Abstract: Methods and devices are disclosed for communicating in a wireless network using multi-protocol label switching (MPLS). A network service node is configured to send identical packets substantially simultaneously to each of a serving network access station and one or more target network access stations via two or more respective MPLS tunnels in response to a handoff trigger message. Additional embodiments and variations are also disclosed.

Abstract: A method and apparatus that receives an IP packet and encapsulates the packet with an IP header. Further, time-domain multiplexed voice data is received and converted into VoIP packets. Still further, Signaling System 7 (SS7) compliant signals are decoded. The decoded SS7 signals are received and encapsulated prior to transmission to a telephony device.

Abstract: A backplane employed in a switch fabric, having the capability to allow signal communication between at least two modules. Two or more of the modules being adapted to employ different topologies from the following types of topologies: star, dual star, mesh, and cascaded mesh.

Abstract: A network device architecture comprising a fault-tolerant array of network processing modules, selectively coupled to trunk interface boards through main fabric switch(es) using high-bandwidth communication media and selectively coupled to any of a number of media processing modules using low-bandwidth communication media. Network content delivered to the network processing modules for network processing that contain media content are selectively coupled to any of the one or more media processing modules for additional media processing before passing the processed content to the next hop in the path towards the destination computing appliance.

Abstract: A method and system for a network node for attachment to switch fabrics is described. The system includes an access unit to provide access to communications from an external network, a classification element to label received packets with information identifying an associated flow and queue, a mapping element to place the packets into one of a plurality of queues based on the label identifiers, a scheduler to schedule packets in the queues for transmission, and an encapsulation element to encapsulate the scheduled packets into uniform size frames. The uniform size frames may then be transmitted to a next destination through a switch fabric.

Abstract: A method for inverse multiplexing of managed traffic flows over a multi-star switch network includes a source node classifier. The source node classifier, using a traffic-engineering algorithm, classifies incoming traffic based on flow parameters, embeds the flow parameters in a routing table in a node for a flow, places packets from classified flows into Switch-Specific Managed-Traffic Queues (SSMT) and a source node unmanaged traffic queue. A source node switch input scheduler process for a switch selects all managed packets from the SSMT destined for the switch, then selects a single unmanaged packet from the source node unmanaged traffic queue. The source node transmits the packets as classified flows through a switch fabric to the destination node. At the destination node packets transmitted through the switch fabric are sorted by a Switch Output Process and sent to intended output queues.

Abstract: Multiple boards are connected within a chassis, using a multi-port Target Channel Adapter (TCA). Data is transported from a TCA on a board directly to a TCA on another board through a meshed backplane. The meshed backplane is equipped to mount boards via connectors and may consist of a fabric of copper conductors or optical fibers. Communication from TCA to TCA requires placing ports on each individual TCA along with the appropriate input and output buffering. A multi-port TCA capable of performing multiple bridging functions simultaneously i.e., bridging from a high speed serial meshed backplane to multiple local busses, i.e., Gigabit Ethernet, Fibre Channel, and TCP/IP devices, is referred to as a Fabric Interconnect Chip (FIC).

Abstract: A method of providing virtual output queue feedback to a number of boards coupled with a switch. A number of virtual queues in the switch and/or in the boards are monitored and, in response to one of these queues reaching a threshold occupancy, a feedback signal is provided to one of the boards, the signal directing that board to alter its rate of transmission to another one of the boards. Each board includes a number of virtual output queues, which may be allocated per port and which may be further allocated on a quality of service level basis.

Abstract: Multiple voice channels are aggregated into a packet having a segmented data structure and sent over a packet network. The segmented data structure includes segment IDs, corresponding data segments and a packet header arranged so that all data is aligned on 8-byte boundaries for efficient processing by 64-bit processors. The data segment represents one or more milliseconds of digitized voice data, and the segment ID explicitly identifies the voice channel associated with the digitized voice data without reference to any other data in the data structure.
