  • Patent number: 9622289
    Abstract: End-to-end delay adaptation in conjunction with connected discontinuous reception (C-DRX) mode communication during cellular voice calls. A Voice over LTE (VoLTE) call may be established between a first wireless user equipment (UE) device and a second UE. End-to-end delay between real-time transport protocol (RTP) layers of the first UE and the second UE for the VoLTE call may be estimated. The end-to-end delay may be compared with one or more thresholds A C-DRX cycle length for the VoLTE call may be modified based on comparing the end-to-end delay with the one or more thresholds.

  • Patent number: 9621410
    Abstract: A method of localizing failures occurring along a transmission path is provided. A data signal is transmitted along the transmission path, which comprises a path segment. A first network node performs a tandem connection monitoring source function of a tandem connection. A second network node monitors the transmission along the path segment, by performing a tandem connection monitoring sink function. When the first network node detects a failure of the data signal, the first network node enters information indicating a data signal failure into the data signal's overhead field. When the second network node detects a failure by the tandem connection monitory sink function, the second network node enters information into the overhead field. When a third network node detects a failure of the data signal, the third network node uses the information in the overhead field to determine whether the failure occurred within or outside of the path segment.

  • Patent number: 9590820
    Abstract: An apparatus includes a virtual switch hosted at a first network device. The virtual switch is configured to receive a data packet from a first virtual resource hosted at the first network device to be sent to a second virtual resource hosted at a second network device. The virtual switch is configured to encapsulate the data packet to define an encapsulated data packet using a tunnel header, which has a first portion associated with the first and second network devices, and a second portion associated with a data flow between the first and second virtual resources when the data packet is sent from the first network device to the second network device. An Internet Protocol network can use the second portion of the tunnel header to load balance the data packet with respect to other data packets sent from the first network device to the second network device.

  • Patent number: 9526062
    Abstract: In a wireless sensor network having a plurality of mobile sensor nodes (62, 63, 64, 65), a sink (70) is provided and re-positioned as required by assigning the role of sink to one of the mobile sensors at a time. Re-positioning involves finding candidate sinks in the vicinity of a current sink, a temporary sink or a central candidate in the network; judging the suitability of each candidate, for example by estimating the data throughput likely to be achieved if each candidate is selected as the new sink; and transferring the role of sink to the best candidate found. The temporary sink or central candidate may be selected with the aid of a positioning system (80) of the network. Suitability of a candidate sink may take into account a desired transmission rate of each sensor node in the vicinity of a candidate, this desired rate being found from a 3-D look-up table of each sensor.

  • Patent number: 9467307
    Abstract: In PCI-Express and alike communications systems, it is often desirable to keep track of order of arrival into different queues of packets that will later compete for servicing by a downstream resource of limited bandwidth. Use of time stamping to determine order of arrival can be a problem because time of arrival between different packets entering respective ones of plural queues can vary greatly and thus the number of bits consumed for accurately time stamping each packet can become significant. Disclosed are systems and methods for tracking the arrival orders of packets into plural queues by means of travel-along dynamic counts rather than by means of high precision time stamps.

  • Patent number: 9456444
    Abstract: In one embodiment, a network of nodes is configured to communicate according to a configuration of Available Routing Construct (ARC) chains as well as monitoring communication in the network, and/or selectively controls whether or not provisioned particular links will be used. One embodiment colors nodes of the network (e.g., a wireless deterministic network) along different paths through the network and marks packets with the color of each traversed node to track a path taken by a packet. One embodiment sends a particular packet through the network and marks over which links the packet traverses and aggregates these traversed links of other copies of the particular packet. One embodiment controls whether or not the provisioned time slots are used based on flooding a control packet through the network with enable or disable information for each of these links.

  • Patent number: 9300422
    Abstract: The method for detecting and managing a synchronization failure of a transparent clock is used in a packet network in order to determine and correct residence time of time-stamped packets within a traversed element of said network. The transparent clock is part of a Master/Slave synchronization path including a plurality of network elements and their associated transparent clocks. The method includes transmitting time-stamped packets from the Master to the Slave through different synchronization paths in order to have the Slave receiving multiple time signals transmitted through different paths, and determining a failure within a transparent clock of a failed/failing synchronization path if the time signal provided by said failed/failing path differs from the time signal provided by the other transmitting path(s).

  • Patent number: 9253146
    Abstract: Preventing duplicate sources in a network that uses network address port translation on an established connection. In response to receiving an inbound packet at a destination host, input values are obtained therefrom and used to consult a mapping. If no match is found, a translation is performed, whereby a determination is made as to whether or not a port number is available within a range of port numbers that comply with a security association governing the connection. If so, an available port number is assigned to the connection, thereby avoiding a possibility of a duplicate source. If a port number is not available, the packet is rejected.
