  • Patent number: 9479442
    Abstract: Datalink frames or networking packets contain protocol information in the header and optionally in the trailer of a frame or a packet. We are proposing a method in which part of or all of the protocol information corresponding to a frame or a packet is transmitted separately in another datalink frame. The “Separately Transmitted Protocol Information” is referred to as STPI. The STPI contains enough protocol information to identify the next hop node or port. STPI can be used avoid network congestion and improve link efficiency. Preferably, there will be one datalink frame or network packet corresponding to each STPI, containing the data and the rest of the protocol information and this frame/packet is referred to as DFoNP. The creation of STPI and DFoNP is done by the originator of the frame or packet such as an operating system.

  • Patent number: 9450703
    Abstract: A network is configured to utilize available bandwidth to conduct bulk data transfers without substantially affecting the successful transmission of time-sensitive traffic in the network. In order to avoid this interference, the packets carrying data for bulk data transfers are associated with a low priority class such that the routers of the network will preferentially drop these packets over packets associated with the normal traffic of the network. As such, when the normal traffic peaks or there are link or equipment failures, the normal traffic is preferentially transmitted over the bulk-transfer traffic and thus the bulk-transfer traffic dynamically adapts to changes in the available bandwidth of the network. Further, to reduce the impact of dropped packets for the bulk-transfer traffic, the packets are encoded at or near the source component using a loss-resistant transport protocol so that the dropped packets can be reproduced at a downstream link.

  • Patent number: 9294549
    Abstract: Bandwidth on the Internet and intranets is highly variable and unreliable, two properties that can make streaming digital media content difficult. In a virtualization system (e.g., virtual desktop, remote desktop, remote application, and the like), this is especially so based on different bandwidths available to the session host and the session client. Methods and systems for emulating a bandwidth of a client device in a virtualization system are described. When the session host is executing an application (e.g., a digital media application), the session host may emulate the bandwidth of the session client by hooking into and throttling data over one or more APIs associated with the digital media application, thereby tricking the application into making a bandwidth determination based on the emulated bandwidth of the session client, rather than based on the bandwidth of the session host.

  • Patent number: 9276870
    Abstract: A packet switching node is coupled by links to other nodes of a network, and receives and assembles packets belonging to a specified packet flow, into bursts of packets with a burst control packet indicating a sequence of the burst in the flow. The node determines whether to distribute the flow across several links. If so, the bursts are then forwarded for switching to the output ports of the selected links. Distributing the flow over multiple links can enable more flexible and efficient filling of allocated bandwidth on links, as traffic increases. To reduce the risk of losing the order of packets the sequence of the bursts is indicated for use in reordering at intermediate nodes during transmission through the network.

  • Patent number: 9083554
    Abstract: When an internal terminal (TM1 to TMn) replaced with another terminal due to the breakdown or the model upgrading and the DHCP function allocates a new private address for the MAC address of the terminal after replacement, the newly allocated private address is managed in association with physical ports (PP1 to PPn) in an expansion NAPT table. Then, in this state, when an IP packet is delivered from an external terminal (TM0) on the side of a WAN(2), the transmission destination address of this IP packet is converted to the private address of the internal terminal after conversion in accordance with the expansion NAPT table using the physical ports as a key.

  • Patent number: 9030934
    Abstract: Systems and methodologies are described that facilitate providing quality of service (QOS) functionality on a host device or tethered processor to conserve resources on a network device. In particular, the host device/tethered processor can classify QOS data and manage QOS flows, transmitting data by flow to the network device. The data from the QOS flows can be tagged to identify the flow and/or characteristics thereof allowing the wireless device to simply route the data to its respective flow. Thus, the network device is saved from such classification and flow management freeing resources to provide increased performance and decreased power consumption.
