A device and a method for analyzing service-oriented communication in a communications network. A data packet includes a first header of an application layer for service-oriented communication, and a second header of a presentation layer, a session layer, a transport layer, a network layer, a data link layer, or a physical layer. The data packet is analyzed based on information concerning a sender and/or receiver of the data packet from the first header and as a function of information concerning a sender and/or receiver from the second header, for whether or not the data packet meets a criterion, the criterion defining a setpoint value for the sender and/or receiver in the first header as a function of the content of the second header, and/or the criterion defining a setpoint value for the sender and/or receiver in the second header as a function of the content of the first header.

Device and method for intrusion detection in a computer network. A data packet is received at an input of a hardware switch unit, an output of the hardware switch unit being selected for sending the data packet or a copy as a function of data link layer information from the data packet and of a hardware address from a memory of the hardware switch unit. An actual value from a field of the data packet is compared by a hardware filter with a setpoint value for values from this field, the field including data link layer data or network layer data, and the data packet or a copy of the data packet being provided to a computing device as a function of a result of the comparison. The analysis for detecting an intrusion pattern in a network traffic in the computer network id carried out by the computing device.

Systems, methods, and software for inter-PLMN communications. In one embodiment, a roaming hub receives a message from a sending entity across an N32 interface, and determines whether the message includes an HTTP custom header that indicates a PLMN that is validated. When the message as received does not include the HTTP custom header, the roaming hub adds the HTTP custom header to the message that indicates the PLMN of the sending entity, integrity protects the HTTP custom header, and forwards the message toward a receiving entity.

An artificial intelligence chip and a data operation method are provided. The artificial intelligence chip receives a command carrying first data and address information and includes a chip memory, a computing processor, a base address register, and an extended address processor. The base address register is configured to access an extended address space in the chip memory. The extended address processor receives the command. The extended address processor determines an operation mode of the first data according to the address information. When the address information points to a first section of the extended address space, the extended address processor performs a first operation on the first data. When the address information points to a section other than the first section of the extended address space, the extended address processor notifies the computing processor of the operation mode and the computing processor performs a second operation on the first data.

A communication system and a communication method for reporting a compromised state in one-way transmission are provided. The communication method includes: receiving a packet by a first port; coupling an error checking circuit to the first port, wherein the error checking circuit checks a header of the packet; coupling a first unidirectional coupler to the first port and the error checking circuit, and coupling a second unidirectional coupler to the first port and the error checking circuit; in response to an error being in the header, disabling the first unidirectional coupler and the data inspection circuit and enabling the second unidirectional coupler by the error checking circuit; receiving the packet from the communication device by a receiving server; and in response to determining the received packet is incomplete by the receiving server, outputting the compromised state by the receiving server.

Technologies for end of frame marking and detection in streaming digital media content include a source computing device communicatively coupled to a destination computing device. The source computing device is configured to encode a frame of digital media content and insert an end of frame marker into a transport stream header of a network packet that includes an encoded payload corresponding to a chunk of data of the frame of digital media content. The destination computing device is configured to de-packetize received network packets and parse the transport stream headers of the received network packets to determine whether the network packet corresponds to an end of frame of the frame of digital media content. The destination computing device is further configured to transmit the encoded payloads of the received network packets to a decoder in response to a determination that the end of frame network packet has been received. Other embodiments are described and claimed.
