A wireless communication method for reducing the receival of unwanted data is provided. The wireless communication method for a TCP session includes the steps of determining whether a TCP session associated with a first subscriber identity module (SIM) of the UE is not required; and in response to determining that the TCP session is not required, the processor terminates the TCP session.

A system for batched User Datagram Protocol (UDP) processing, on a send operation, combines multiple UDP packets into a plurality of packet batches to indicate on a plurality of sockets based at least in part on a packet batch size. Each packet batch is to be indicated to a corresponding one of the plurality of sockets to convey the plurality of packet batches to a network stack. One call is performed for each indicated socket of the plurality of sockets based on the packet batch size to convey each packet batch to the network stack. The network stack performs a single look up operation and a single network security inspection operation once per packet batch. In response to performing the one call, the plurality of packet batches are then sent to a network adapter or an application. The system thereby operates more efficiently and/or is more scalable.

The disclosure relates to techniques for network protocol conversion, in particular to a first packet data conversion device (810) for a sender, the packet data conversion device (810) comprising: a data interface (811) configured to provide first packet data (813) according to a first network protocol (814), in particular according to a Datagram Congestion Control Protocol, DCCP, wherein each packet of the first packet data (813) comprises a first packet header (815); and a converter (812) configured to convert the first packet data (813) into second packet data (817), wherein the conversion is based on rearranging contents of the first packet header (815), wherein the rearranged first packet header (819) indicates that the second packet data (817) is generated according to a second network protocol (818), in particular according to a User Datagram Protocol,UDP or according to a UDP-Lite protocol.

In an example, a first Internet Protocol (IP) address is assigned to a first service. The first service includes a plurality of pods and is to operate on a first port. A first node on which the first IP address is to be configured is selected from among a plurality of nodes based on a number of IP addresses configured on each of the plurality of nodes. Further, the first IP address is configured on the first node. The first IP address is assigned to a second service as well. The second service comprises a plurality of pods and is to operate on a second port.

Disclosed herein are a method for broadcast gateway signaling and an apparatus for the same. The apparatus for broadcast gateway signaling includes an inner packet generator for generating an inner packet corresponding to the inner layer of a tunneling system; an outer packet generator for generating an outer packet corresponding to the outer layer of the tunneling system; an outer packet header generator for generating the header of the outer packet; and an STL transmission unit for transmitting the outer packet to a transmitter via a Studio-to-Transmitter Link (STL).

A network device may receive an IPv6 packet that includes an IPv6 source address and an IPv6 destination address. The network device may determine, based on the IPv6 packet including an extension header that includes an address prefix option, whether to translate the IPv6 packet into an IPv4 packet. Additionally, based on a determination to translate the IPv6 packet into the IPv4 packet, the network device generates an IPv4 packet that includes an IPv4 source address and an IPv4 destination address. Because the PLAT unit may make the determination whether to translate the IPv6 packet into an IPv4 packet based on the IPv6 packet including the address prefix option instead of based on the IPv6 source address including a customer-translation (CLAT) source prefix, it may be unnecessary to distribute the CLAT source prefix to the network device.

A transmission control protocol communications method between a first device and a second device. The method includes the following acts: a) the first device, or a proxy connected to the first device, collects information about existence of network address translators and/or firewalls, if any, placed in series on at least one possible communications path between the first device and the second device and known to the first device or to the proxy connected to the first device; b) the first device or the proxy creates an entry in at least one such network address translator and/or firewall, the entry including at least one IP address and/or at least one port number of the first device; and c) the first device or the proxy transmits to the second device the at least one IP address and/or the at least one port number in a TCP option.

A distribution network system having a plurality of nodes using a scheme for data-centric object-oriented communication (DDS) effectively manages the frequently occurring connections for each node and the real-time addition or deletion of a node. Each node includes a gateway connected to a Wide Area Network (WAN) and configured to transmit and receive a message using a Real-Time Publish-Subscribe (RTPS) protocol that applies simple tunneling to communicate as if all nodes communicate in a Local Area Network (LAN), and to insert magic information into a header of the message, the inserted magic information including source IP information of the message, destination IP information of the message, and destination User Datagram Protocol (UDP) information of the message.

The present technology relates to a transmission apparatus, a transmission method, a reception apparatus, and a reception method that enable channel selection information and time information to be transmitted effectively.

A transmission apparatus acquires channel selection information for selecting a service and time information used for synchronizations on a transmission side and a reception side, generates, as a physical layer frame constituted of a preamble and a data portion, the physical layer frame in which specific information including at least one of the channel selection information and the time information is arranged at a head of the data portion right after the preamble, and transmits the physical layer frame as digital broadcast signals. The present technology is applicable to IP packet broadcasting, for example.

A method of monitoring traffic, the method being carried out by a router acting as a gateway between a first and second network, the method comprising: after establishment of a TCP connection between a first device on the first network and a second device on the second network: receiving a plurality of data packets sent from the first device over the TCP connection; sending a TCP ACK packet to the first device in response to each data packet of the plurality of data packets; storing said data packets without sending them to the second device; examining at least part of the plurality of the stored data packets in order to determine whether to block or allow the TCP connection; in the event that it is determined to allow the TCP connection: sending each of the stored data packets to the second device; in the event that it is determined to block the TCP connection: sending a TCP RST message to each of the first and second devices in order to close the TCP connection.
