A system for efficient routing of an (OAM) frame in an Ethernet switch receives an OAM frame at a first port; building a first classification key dependent on an OAM frame header; classifies in a context of the first port to create a first classification; resolves action dependent on the first classification; modifies the first classification key to create a second classification key; classifies the frame in a context of the second port to create a second classification; sends the second classification key to an OAM engine coupled to the Ethernet switch for modification into a third classification key; receives the third classification key from the OAM engine; modifies the third classification key into a final classification key; modifies the header of the OAM frame with the final classification key; and sends the modified OAM frame to a switching fabric of the Ethernet switch.

Wireless communications are described. A wireless device may determine a first transmission power for a first signal and a second transmission power for a second signal. The wireless device may reduce signal transmission power of one or more of the first signal or the second signal, based on a calculated power value exceeding an allowable transmission power. The wireless device may reduce the signal transmission power during an overlap period or a non-overlap period, based on a duration of an overlap of the first signal with the second signal.

Described herein are techniques, devices, and systems for handling Session Initiation Protocol (SIP) messages with malformed header fields. A communication device that receives a SIP message from an additional communication device may identify one or more identified header fields of a plurality of first header fields in a message header of the SIP message that correspond to (e.g., match) one or more second header fields in a list of second header fields accessible to the communication device. If the communication device determines that the one or more identified header fields are not malformed, the communication device may process the SIP message without regard to remaining header fields in the message header. If, however, the communication device determines that at least one identified header field of the one or more identified header fields is malformed, the communication device may reject the SIP message.

A message processing method and device, a storage medium, and an electronic device are provided. The method includes: acquiring a first message sent by an Ingress Process Engine (IPE) of a switch, and acquiring a second message sent by an Egress Process Engine (EPE) of the switch, a header of the first message includes data collected by an Inband Network Telemetry (INT), and the first message is the same as the second message; identifying the first message and the second message as a same message stream according to key information of a message header; and combining and reorganizing the first message and the second message identified as the same message stream into an INT report, and sending the INT report to a target device. The problem in the related art that network state monitoring at a protocol layer consumes a large amount of network bandwidth is solved.

A message processing method and device, a storage medium, and an electronic device are provided. The method includes: receiving a message to be processed by means of a Bidirectional Forwarding Detection (BFD) processing engine of a chip, the BFD processing engine storing head Maintenance End Points (MEP); if a head MEP corresponding to the message to be processed is not found in the BFD processing engine of the chip, judging whether to forward the message to be processed to a processor; and if a judgment result is yes, saving the information of the message in a client MEP in the processor. The problem in the related art that an MEP on a Head side in RFC8562 only transmits but does not receive a BFD message, an MEP on a Tail side only receives but does not transmits a BFD message and thus the requirements cannot be satisfied is resolved.

A method implemented by a first node in a segment routing (SR) network domain includes receiving, from a second node of another network domain, a packet configured to pass through the SR network domain in accordance with segment identifiers (SIDs). The method also includes obtaining compressed SIDs corresponding to some of the SIDs. The method includes generating a segment routing header (SRH) having a list of segments. The method further includes adding the SRH to the packet and forwarding the packet with the SRH to a third node in the SR network domain.
