Abstract: A method is presented of transporting data packets over a telecommunications transport network. The data packets are carried by a plurality of bearers. For each of the bearers, independently of the other bearers, bandwidth profiling is applied to the data packets of the bearer to designate as ‘green’ data packets that are conformant with a predetermined maximum Information Rate for the bearer. One or more data packets is buffered for up to a predetermined maximum ‘green’ buffer time, during which if transporting the data packet would not cause the maximum information rate of the bearer to be exceeded, the data packet is designated as a ‘green’ data packet. The data packets are forwarded for transporting over the transport network. If there is insufficient bandwidth available in the transport network to transport all data packets, data packets that are not designated as ‘green’ data packets are discarded, so as not to be transported through the transport network.

Abstract: Methods, devices, non-transitory processor-readable instructions, and systems for a VOIP application server associated with a VOIP application to improve performance of a target computing device for IP communications via the VOIP application. An embodiment method may include determining whether the target computing device is likely to be called using the VOIP application during a contact period, and directing the target computing device to adjust a performance setting for receiving an IP communication in response to determining a likelihood the device will be called during the contact period. When a call is likely, the performance setting may be raised via transmitting dummy traffic to target computing device, activating a quality-of-service on an Rx interface corresponding to the VOIP application and the target computing device, and/or transmitting a message directing the target computing device to utilize an aggressive slot cycle index setting or an aggressive discontinuous reception setting.

Abstract: Systems and methods for simultaneous sampling of serial digital data streams from multiple analog-to-digital converters (ADCs), including in distributed antenna systems, are disclosed. In one embodiment, a controller unit samples a plurality of serial digital data streams simultaneously. To allow the controller unit to sample the multiple serial digital data streams simultaneously from a plurality of ADCs, the controller unit is configured to provide a plurality of data input ports. Each of the ADCs is coupled to a common chip select port and clock signal port on the controller unit. The controller unit communicates a chip select signal on the chip select port to activate all of the ADCs simultaneously to cause each of the ADCs to provide its respective digital data stream to the respective data input port of the controller unit simultaneously for sampling. As a result, fewer or lower-cost components may be used to sample multiple ADCs.

Abstract: Embodiments disclosed herein provide advantageous methods and systems that use multicast communications via unreliable datagrams sent on a protected traffic class. These methods and systems provide effectively reliable multicast delivery while avoiding the overhead associated with point-to-point protocols. Rather than an exponential scaling of point-to-point connections (with expensive setup and teardown of the connections), the traffic from one server is bounded by linear scaling of multicast groups. In addition, the multicast rendezvous disclosed herein creates an edge-managed flow control that accounts for the dynamic state of the storage servers in the cluster, without needing centralized control, management or maintenance of state. This traffic shaping avoids the loss of data due to congestion during sustained oversubscription. Other embodiments, aspects and features are also disclosed.

Abstract: Selecting an edge-server set in a wireless network comprises generating channel-quality measurements of wireless links between available nodes; determining a network topology state based on the measurements; calculating a performance metric for each candidate edge-server set; and selecting a candidate edge-server set based on the performance metric. An iterative process may be employed for selecting the best edge-server set. The iterative process may employ a trellis-exploration algorithm. A back-pressure routing algorithm may be used to calculate the performance metric. A server processes a request from a client residing on a wireless network by determining if another client on the wireless network has the requested object; determining if the requesting client can communicatively couple to the other client; and directing the request to the other client.

Abstract: A method for a connection mode terminal to hand over between a home cell and a public cell in a mobile communication system is provided. In the mobile communication system including the home cell and the public cell, a region of the terminal is determined and a random access channel for the handover is pre-allocated. When the normal handover from the home cell to the public cell fails, the access to the public cell is accomplished using the pre-allocated random access channel. Therefore, the handover failure rate can be lowered.
