Abstract:
A plurality of network characteristics of a wireless network are determined and a plurality of TCP session parameters are updated. The network characteristics may be determined based at least in part on a comparison of the estimated bandwidth and estimated propagation delay of the wireless network and the typical bandwiths and propagation delays of one or more wireless networks. The TCP session parameters may be updated based at least in part on the network characteristics. The TCP session parameters may be used to limit the congestion window, retransmission timeout and slow start threshold.
Abstract:
A magnetically-assisted chip assembly unit for assembling at least one chip having a mounting surface and an attachment surface, wherein the attachment surface supports a magnetisable layer thereon and opposes said mounting surface, onto a substrate that has a corresponding chip mounting surface. The unit comprises a template wafer having at least one recess adapted to accommodate therein said chip; and a master wafer having at least one magnetisable element; wherein the template wafer is mounted on the master wafer and said magnetisable element is located at least proximate to the at least one recess such that the magnetisable element is capable of manipulating the chip into the recess, via its magnetisable layer when the magnetisable element is magnetized and generates a magnetic field. Once in the recess, the attachment surface of the chip faces at least a portion of the recess and the mounting surface of the chip faces an opening of the recess.
Abstract:
Embodiments of the present disclosure may provide a network node that communicates data with a second network node over a plurality of networks. The network node includes a fixed micronode and a mobile micronode. The fixed micronode sends a packet to the mobile micronode, where the packet includes a portion of the data and a fixed connection-tuple. The mobile micronode includes replaces the fixed connection-tuple in the packet with a mobile connection-tuple, and forwards the replaced packet to the second network node.
Abstract:
An overlay network of logical gateways are used to store and forward packets from a source terminal to a destination terminal regardless of whether the terminals are mobile, intermittently inactive, inside a private network, or in different access network. The logical gateways maintain inter-network connectivity, even as active terminals move in and out of different access networks.

Abstract:
A retransmission timer of a Transmission Control Protocol (TCP) session is set based at least in part on the predicted mean round trip time differential of the TCP session. For example, in one embodiment, after receiving a non-duplicate acknowledgment (305), the predicted mean round trip time differential (315) of the TCP session would be determined and used to further determine the predicted round trip time of the next transmitted data segment (320). In one embodiment, the predicted round trip time of the next transmitted data segment would be used to determine a retransmission timeout (325), the value of which would be inserted into a retransmission timer.

Abstract:
During a Transmission Control Protocol (TCP) session, a congestion window and slow start threshold may be limited to a range defined by a minimum congestion window and a maximum congestion window based at least in part on the network type of a wireless network. The network type of a wireless network may be determined based in part on one or more round trip times of one or more data segments and one or more TCP session parameters are set to corresponding stored session parameters that are associated with the network type.

Abstract:
An inter-departure time of a pair of TCP segments, or a mean inter-departure time of a block of TCP segments, is determined and an inter-arrival time of a pair of non-duplicate acknowledgments is determined. The bandwidth of a data network may be estimated based at least in part on the inter-arrival time if the inter-arrival time is not less than the inter-departure time or the mean inter-departure time.
