Abstract: A method is implemented by a network device where the method performs a trace flow process in a packet processing pipeline of the network device. The packet processing pipeline includes a trace table and a forward table. The method encompasses forwarding a trace packet to the trace table, forwarding a copy of the trace packet to a trace analyzer in response to determining that a trace bit is set in the trace packet, forwarding the trace packet to the forward table, and determining a next stage of the packet processing pipeline based on trace packet meta data and a value stored in a trace register.

Abstract: Disclosed is an electronic device includes a wireless communication circuit configured to support Bluetooth communication; at least one processor operatively connected to the wireless communication circuit; and a memory operatively connected to the at least one processor, wherein the memory stores one or more instructions that, when executed, cause the at least one processor to perform a plurality a plurality of operations comprising: receiving first data transmitted from a first external electronic device via a first link between the electronic device and the first external electronic device; when an acknowledgement (ACK) is not received from a second external electronic device, determining that the first external electronic device or the electronic device should retransmit the first data to the second external electronic device based on at least one of status information about the electronic device, status information about the first external electronic device, communication quality of the first link, or co
