Packet flow control in a header of a packet
Techniques for controlling packet flows are described. In an example, a packet is sent on a virtual network. The packet's header includes scoping data that indicates a network boundary within which the packet is permitted and/or prohibited to flow. A network virtualization device of a substrate network receives the packet. The network virtualization device determines the scoping data from the header and, based on network configuration information, determines the forward flow of the packet. If the forward flow falls within a permitted network boundary indicated by the scoping data, the network virtualization device sends the packet forward. Otherwise, the packet is dropped. |

The line card generates a system clock signal in a phase-locked loop and generates a SYNC output signal by dividing the system clock signal in a divider circuit. The SYNC output signal is fed back to an input terminal as a SYNC feedback signal. A time stamp is generated based on receipt of the SYNC feedback signal. The line card determines a time between the SYNC input signal and the SYNC feedback signal based on the first time stamp and the second time stamp. The timing of the SYNC output signal is adjusted based on the time difference using a coarse time adjustment by adjusting a divide ratio of the divider circuit and using a fine time adjustment in the phase-locked loop based on a residue of a remainder of the time difference not accounted for by the coarse time adjustment. |

Reduced complexity decoder with improved error correction and related systems methods and devices
Reduced complexity decoders with improved error correction and related systems, methods, and apparatuses are disclosed. An apparatus includes an input terminal and a processing circuitry. The input terminal is provided at a physical layer device to receive, from a network, a low density parity check (LDPC) frame including bits. The bits correspond to log-likelihood ratio (LLR) messages indicating probabilities that the bits have predetermined logic values. The processing circuitry is to saturate LLR values of a portion of the LLR messages corresponding to known bits of the LDPC frame to a highest magnitude value represented by the LLR messages, and pass the LLR messages between check nodes and message nodes. The message nodes correspond to the bits. The check nodes correspond to parity check equations of a parity check matrix. |

Memory in logic physical unclonable function
Methods and systems are directed to creating a physical unclonable function (PUF) on a Field Programmable Gate Array (FPGA) and generating a unique signature for a device. The method includes, in part, designing a PUF by taking advantages of programmable logic elements on the FPGA, and extracting uninitialized values associated with one or more storage elements comprised in the PUF when the FPGA is powered up. The extracted uninitialized values can be combined to generate the unique signature for the device. The one or more storage elements can be bi-stable memory cells that are mapped to look up tables (LUTs) on the FPGA. The coordinates of these LUTs can be determined based on hamming distance analysis. Alternatively, the one or more storage elements can be memory cells associated with boundary scan cells of a boundary scan chain. |
