摘要： A first communication device is configured to process packets that conform to a first physical layer (PHY) protocol for wireless vehicular communications and packets that conform to a second PHY protocol for wireless vehicular communications. The first communication device determines that one or more second communication devices neighboring the first communication device are not capable of processing packets that conform to the second PHY protocol. The first communication device transmits a first packet to a third communication device that is configured to process packets that conform to the first PHY protocol and packets that conform to the second PHY protocol. The first packet indicates that the one or more second communication devices neighboring the first communication device are not capable of processing packets that conform to the second PHY protocol to inform the third communication device of the one or more second communication devices.

摘要： Security features for a wireless communications system including encryption and decryption of communications, secure key exchange, secure pairing, and secure re-pairing are provided. The encryption/decryption mechanism uses AES-256 block cypher with counter mode to generate blocks of cypher bits used to encrypt and decrypt communications between a master and devices. Session keys are generated using a random salt and a counter value. The random salt is generated using a secure random number generator. A master key or device key is also used in generating session keys. Impermanent session keys are used to encrypt/decrypt finite amount of data. Thereafter, the session key is replaced and cypher bits are generated using the new session key. A synchronized key jump procedure ensures that the master and device switch to the new session key at the same time.

摘要： Rapid channel failure detection and recovery in wireless communication networks is needed in order to meet, among other things, carrier class Ethernet channel standards. Thus, resilient wireless packet communications is provided using a physical layer link aggregation protocol with a hardware-assisted rapid channel failure detection algorithm and load balancing, preferably in combination. This functionality may be implemented in a Gigabit Ethernet data access card with an engine configured accordingly. In networks with various topologies, these features may be provided in combination with their existing protocols.

摘要： This disclosure provides a method for sending and receiving a clock synchronization packet in FlexE. The method includes: generating, by a sending apparatus, indication information and a plurality of data blocks, where the plurality of data blocks are obtained by encoding a first clock synchronization packet, the indication information is used to indicate a first data block, and the first data block is a data block used for timestamp sampling in the plurality of data blocks; determining, by the sending apparatus, according to the indication information, a moment at which the first data block arrives at a medium dependent interface MDI of the sending apparatus, and generating a sending timestamp, where the sending timestamp is used to record a sending moment of the first clock synchronization packet; generating a second clock synchronization packet carrying the sending timestamp; and sending, by the sending apparatus, the second clock synchronization packet.

摘要： A processing system includes a controller of a transmitting module for transmitting data to a receiving module across an interconnect compliant with a processor interconnect protocol. The controller indicates the beginning and end of a variable-length data burst using data primitives that are N symbols (bytes) in length, rather than using data primitives that are M symbols in length, as specified by the processor interconnect protocol, where N
