  • Patent number: 9594842
    Abstract: Roughly described, a network interface device is assigned a maximum extent-of-search. A hash function is applied to the header information of each incoming packet, to generate a hash code for the packet. The hash code designates a particular subset of the table within which the particular header information should be found, and an iterative search is made within that subset. If the search locates a matching entry before the search limit is exceeded, then the incoming data packet is delivered to the receive queue identified in the matching entry. But if the search reaches the search limit before a matching entry is located, then device delivers the packet to a default queue, such as a kernel queue, in the host computer system. The kernel is then responsible for delivering the packet to the correct endpoint.

    Abstract: Computer communications that are to be recorded are visible to a network interface on a recording computer. The network interface receives the packets to be recorded. The network layer of the recording computer implements a subset of the normal IP module in the network layer. Instead of checking every IP packet, the IP module in the network layer assumes that most IP packets are correctly addressed, internally consistent and of the expected protocol type. The recording computer allocates the received packets to a recording session based upon the value of a field that is at a fixed position within the packet. Packets that are allocated to a session are recorded or associated with other packets that have been allocated to the same session.

  • Patent number: 9451054
    Abstract: A reliable communication protocol RUDP is provided to transfer data between two systems connected in a network. Working over the unreliable UDP transport layer protocol, the RUDP protocol adds an acknowledging mechanism to otherwise unreliable UDP packets. Contrary to the TCP transport layer protocol, which establishes a connection before any data transfer, the RUDP is used to transfer short amounts of information or messages, so a connectionless communication is used. In a connectionless context the complexity of the encoding-decoding algorithm and the amount of memory consumed by the protocol is reduced. Such characteristics makes the RUDP protocol suitable for its implementation in systems with limited memory and speed, like low processing power 8-bit microcontrollers. Furthermore, by programming the RUDP protocol over the UDP protocol, its implementation in a personal computer can be made with common programming tools.

  • Patent number: 9414388
    Abstract: A wireless transmit/receive unit (WTRU) determines (1) whether the WTRU is transmitting as much scheduled data as allowed by a current Serving_Grant, (2) whether the WTRU has enough power to transmit at higher data rate, and (3) based on a same power offset as a currently selected E-DCH transport format combination (E-TFC), whether total E-DCH buffer status (TEBS) would require more than predetermined period to be transmitted with the current Serving_Grant.times.a ratio of active processes to a total number of processes. If criteria (1)-(3) are met, the WTRU sets the happy bit to “unhappy.” If MAC-i/is is configured, the WTRU evaluates criteria (2) by identifying an E-TFC that has a transport block size at least x bits larger than a transport block size of the currently selected E-TFC, and determining whether the identified E-TFC is supported based on a same power offset as the currently selected E-TFC.

  • Patent number: 9397857
    Abstract: Some embodiments of the invention provide a method of tunneling a data packet by encapsulating the data packet with a protocol header and specifying information in the fields of the header in a manner that a network switch can offload processing tasks to its network interface controller. The switch on a transmit side sends the processed data packet through the tunnel to another switch on a receive side. The two sides represent the two ends of the tunnel established between the two switches. Each of the transmit and received side switches is controlled by a switch controller, which in some embodiments is implemented as software. The switch controllers and network interface controllers together process the data packet which is being transferred through the tunnel between the switches.

  • Patent number: 9391951
    Abstract: In one embodiment, a first network device is configured for communication with at least a second network device, and implements a gateway. The gateway may comprise, for example, a software gateway. The gateway is configured to receive a packet in a format of a first protocol and to determine if the packet includes an identifier of the gateway, for example, encoded within a destination address of the received packet. If the received packet does not include the gateway identifier, the packet is forwarded in the format of the first protocol. If the received packet does include the gateway identifier, a network address translation operation is applied to reconfigure the packet in a format of a second protocol different than the first protocol, and the reconfigured packet is forwarded in the format of the second protocol. The first and second protocols may comprise Internet protocols such as IPv6 and IPv4, respectively.
