Abstract: An adaptive load balancer intelligently steers data traffic through a software defined network (SDN) to which the load balancer is operatively coupled. The network has egress ports to which a plurality of servers is connected. The network has an SDN controller which generates statistical information concerning the network. The adaptive load balancer includes a weighted round robin scheduler module which receives client requests and, based on the statistical information generated by the SDN controller, determines a weight to be attributed to each server of the plurality of servers connected to the network. The adaptive load balancer operates in a passive port mode, a passive path mode, an active path mode and an active path with quality of service (QoS) overlay mode.

Abstract: A MCLAG table retains a first port in association with a first identifier. A port control unit controls a first port group to a transmission/reception permitted state when the first port group is set to active, and controls the first port group to a transmission/reception prohibited state when the first port group is set to standby. A relay processing unit relays a frame containing the first identifier as a destination port to the first port group when the first port group is controlled to the transmission/reception permitted state and relays the same to a bridge port when the first port group is controlled to the transmission/reception prohibited state. When the first port group is controlled to the transmission/reception prohibited state, a transmission stop instructing unit instructs a peer device to stop frame transmission to the first port group.

Abstract: Providing a power-saving mode for control channel monitoring in discontinuous reception (DRX) scenarios. Upon waking from a sleep mode at the conclusion of a DRX off period, a baseband modem may transition to a low-power mode configured to receive and decode only a control channel, such as a physical downlink control channel (PDCCH). If the control channel indicates during a DRX on period that communication traffic will be transmitted to the baseband modem, then the baseband modem may transition to a full-power mode to receive the communication traffic. Otherwise, the baseband modem may transition back to the sleep mode. The low-power mode may be implemented by a dedicated set of hardware configured to draw less power than a full set of hardware configured to implement the high-power mode.

Abstract: Cable systems and assemblies integrate a reduced number of twin axial cables to transmit and received in a full-duplex transmission signals at transmission speeds greater than or equal to one hundred Giga bytes per second. The reduced number of twin axial cables comprise four or less twin axial cables, in which each pair forms a single twin axial full-duplex cable for passive or active communication of the signals at multiple different transmission rates concurrently. A processor can be integrated with the twin axial cables and operate to encode the signals for fast transmission speeds at the different transmission rates.

The multicast stream is forwarded through the SPB network in accordance with the multicast tree.

Abstract: A wireless receiver includes a receiver mixer having at least two sets of switches connected to selectively pass a portion of a received RF signal to the mixer's output. Different sets of the switches are activated by different phases of a local oscillator to effect passing of different phases of the RF signal to the output. These outputs are combined in various ways to obtain operation of the main receiver and the wake up receiver modes at harmonically related carrier frequencies with as low as possible subharmonic multi-phase clock generation network. This can be used to detect a wake up signal with a very fast response time, minimal area overhead, minimal power usage, and equal loading to the local oscillator network providing the phases to the mixer to maintain excellent phase balance and precise harmonic selectivity.

Abstract: Various of the disclosed embodiments improve encoding during a network call, such as a Voice Over Internet Protocol (VOIP) connection, by adjusting the size of a data communications packet (“packet”). Particularly, given a corpus of codecs with which to encode data, the embodiments may identify a packet size based upon a common multiple of each codec's minimum raw data size. The packet size may be selected to accommodate the inclusion of data encoded in each codec format, as well as error correction code data, and codec transition commands. The packet size may be tailored to trade off measured latency and data efficiency.

Abstract: In one embodiment, a router located at an exit edge of an autonomous system (AS) receives a data packet in a data plane, and determines a destination of the data packet and an associated AS-path information to the destination. The router may then insert the AS-path information into the data packet, and forwards the data packet with the AS-path information toward the destination, such that a receiving device in a destination AS can validate whether the data packet was routed through a path that was secure from a control plane perspective based on a collection of one or more insertions of AS-path information.

Abstract: A self-organizing backhaul radio (SOBR) and related arrangements are disclosed. A “primary” link between an first SOBR enabled radio and a second SOBR radio includes a secondary transmission link, referred to as a signature control channel (SCC), as a spread spectrum modulated signal embedded within and transmitted simultaneously with the primary link. The SCC transmissions from the first SOBR radio may be utilized by other SOBR enabled radios to determine an interference level to or from the first SOBR radio's primary link. The SCC transmission may be utilized to allow transmit beam forming between SOBR-enabled radios without damaging other friendly SOBR radios within the propagation distance of the transmitted signals based upon the detection of the SCC transmissions.

Abstract: Systems and methods for measuring end-to-end data path delays between a Radio Equipment Controller (REC) and a Radio Equipment (RE) of a base station are disclosed. In one embodiment, a system includes a RE configured to transmit a chirped sine wave signal from the RE to a REC on an uplink data path from the RE to the REC. The REC is configured to correlate a reference chirped sine wave signal and a received signal from the RE, where the received signal includes the chirped sine wave signal. The REC is further configured to determine an uplink data path delay from the RE to the REC based on results of the correlation of the reference chirped sine wave signal and the received signal from the RE on the uplink data path. In another embodiment, a downlink data path delay is measured in a similar manner.

Abstract: A wireless sensor network system includes: sensor terminals and a management terminal. A sensor terminal sends a join request at a first transmission power; and the management terminal calculates the traffic load of nodes on the reception path of the join request. If the number of hops and the traffic load are both within respective permissible ranges, the management terminal sets the reception path as the communication route of the sensor terminal. If the number of hops and/or the load is not within the permissible rage, the management terminal reconstructs the communication path by outputting an instruction to the sensor terminal to make direct connection to the management terminal or a specified node with a low traffic load, at a second transmission power greater than the first transmission power. When receiving the instruction, the sensor terminal transmits to the management terminal or the specified node at the second transmission power.

In one form, the module is used as a node in a network fabric and adds a routing header to packets entering the fabric, maintains the routing header for efficient node-to-node transport, and strips the header when the packet leaves the fabric. In particular, a remote bus personality component is described. Several use cases of the Remote Bus Fabric Personality Module are disclosed: 1) memory sharing across a fabric connected set of servers; 2) the ability to access physically remote Input Output (I/O) devices across this fabric of connected servers; and 3) the sharing of such physically remote I/O devices, such as storage peripherals, by multiple fabric connected servers.

Abstract: Method, apparatus, and systems for reliably transferring Ethernet packet data over a link layer and facilitating fabric-to-Ethernet and Ethernet-to-fabric gateway operations at matching wire speed and packet data rate. Ethernet header and payload data is extracted from Ethernet frames received at the gateway and encapsulated in fabric packets to be forwarded to a fabric endpoint hosting an entity to which the Ethernet packet is addressed. The fabric packets are divided into flits, which are bundled in groups to form link packets that are transferred over the fabric at the Link layer using a reliable transmission scheme employing implicit ACKnowledgements. At the endpoint, the fabric packet is regenerated, and the Ethernet packet data is de-encapsulated. The Ethernet frames received from and transmitted to an Ethernet network are encoded using 64b/66b encoding, having an overhead-to-data bit ratio of 1:32.

Abstract: A transmitting wireless device provides channel access information to a receiving wireless device for the receiving wireless device to make a determination of when to transmit and what transmissions parameters to use for the transmission. The channel access information may be used differently by wireless devices operating in a basic service set and an overlapping basic service set. Channel access information may include fields indicative of transmission power used, signal to noise ratio headroom available, and so on. Channel access information may be generated and transmitted at the PHY layer of an implementation, thus providing a fast delivery to the receiving wireless device.
