20120063448 | System and Method for Uplink Timing Synchronization - A system and method are disclosed for providing uplink timing synchronization in a wireless communication system. The uplink timing synchronization may be provided via a specific message sent from the user equipment to a network access device, or may be calculated based upon data received at the network access device from the user equipment. | 2012-03-15 |
20120063449 | CONFIGURABLE NETWORK SOCKET AGGREGATION TO ENABLE SEGMENTATION OFFLOAD - A network device can implement configurable socket aggregation to enable segmentation offload in the network device. In one embodiment, it is determined, at the network device, to create a network socket for an application of the network device to initiate a network connection for the application. Socket aggregation parameters are determined for the network socket associated with the application. The network socket is defined based, at least in part, on the socket aggregation parameters. A plurality of packets received from the application associated with the network socket are aggregated. It is determined, based on said aggregating the plurality of packets, whether at least one aggregation limit associated with the socket aggregation parameters is reached. An aggregate packet is provided to a network adapter of the network device to perform segmentation offload in response to said determining that at least one aggregation limit associated with the socket aggregation parameters is reached. | 2012-03-15 |
20120063450 | Data Path Processing Information included in the Pseudowire Layer of Packets - Data path processing information is included in the pseudowire layer of pseudowire packets in order to provide information for use in the data path processing of data (e.g., a packet), typically, but not always, included in the payload of the pseudowire packet itself. The pseudowire packet typically includes in corresponding fields: a pseudowire label for identifying a pseudowire type; a pseudowire control word; and payload data. The pseudowire type identifies the structure of the pseudowire control word field and the payload field, including the location of data path meta data, such as in the pseudowire control word field or payload field. This data path meta data identifies one or more attributes for use in processing the payload data. | 2012-03-15 |
20120063451 | SHARED VIRTUAL TUNNELS SUPPORTING MAC LEARNING IN COMMUNICATION NETWORKS - Embodiments herein include systems and methods for providing a mechanism for tunneled data transport within a dual homed access network. A tunnel manager, at a first network connectivity device in a transport network, identifies the transport network configured to interconnect at least two access networks for transporting data traffic between one or more end stations connected to the access networks. The first network connectivity device is coupled to a first access network. The tunnel manager identifies a second network connectivity device. The second network connectivity device is coupled to the first access network to provide the first access network dual homed access to the transport network via the first and second network connectivity devices. The tunnel manager creates a virtual tunnel that connects the first and second network connectivity devices to a third network connectivity device across the transport network. The virtual tunnel defines a same virtual tunnel having multiple paths such that the third network connectivity device learns a single virtual tunnel for device address learning. | 2012-03-15 |
20120063452 | MULTI-SERVICE TRANSPORT APPARATUS WITH SWITCH FOR INTEGRATED TRANSPORT NETWORKS - A multi-service transport apparatus for integrated transport networks that may have an electrical matrix, termination function means handling signals incoming at said apparatus input, a plurality of termination function means interfacing different layers, and adaptation function means. The termination function means handling incoming signals are implemented in input/output port devices; the termination function means interfacing different layers and said adaptation function means are implemented in adapter devices. The matrix performs exclusively the switching of the incoming signals that are already terminated and adapted by said input/output port devices and by said adapter devices and it is transparent with respect to the signal format. The switch may have a time division multiplexing matrix provided with a number of matrix inputs and a number of matrix outputs; source address generators, connected to matrix outputs of the time division multiplexing matrix. | 2012-03-15 |
