4 results about "Packet trace" patented technology

Devices and methods are disclosed, including receiving, by a memory controller of a memory device, a memory request from a host device; collecting packet trace data from the memory request; including the packet trace data in a log stored in a memory array of the memory device; and returning the log to the host device.

Systems, methods, and computer-readable media are provided for path tracing proxy behavior using an external probing appliance. An example method can include generating, at an external probing appliance of a network, a probe packet, the probe packet including a source address, a destination address, and a packet tracing indication in a next header field of the probe packet, the packet tracing indication triggering a proxy source behavior at a source node having the source address and a proxy sink behavior at a sink node having the destination address; sending the probe packet to the source node to trigger a packet tracing mechanism; and receive an updated probe packet from the sink node, the updated probe packet including probe data associated with one or more data flows in the network as the one or more data flows traverse the network from the source node to the sink node.

Embodiments herein describe tracking the number of out of order packets that have been received at a receiver (RX) from a particular transmitter (TX). In one embodiment, the RX maintains a packet tracking bitmap that starts with the expected packet sequence number (EPSN) which is the next (sequential) PSN that should be received at the RX. The RX can use acknowledgement packets to transmit the bitmap to the TX so it knows which OOO packets have been received at the RX. However, the bitmap may be too large to fit into one ACK the entire bitmap, which means segments of the bitmap may be transmitted to the TX using multiple ACKs. As such, in the embodiments herein, the RX can also include a total count of the received OOO packets in each ACK.
