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.

Linked packet tracing techniques for software load balancers are described, as leveraging a client identifier generated to link packet traces between packets of a service provider system. In one example, a client-side packet is received from a client device by a processing system. From this, a client identifier is generated by the processing system based on the client device. In response, a modified client-side packet is generated by the processing system by modifying the client-side packet to include the client identifier. The modified client-side packet is transmitted by the processing system to a server system. A server-side packet is then received by the processing system from the server system. In response, the server-side packet is detected as including the client-identifier. From this, the server-side packet is linked to at least the modified client-side packet based on the detecting, and the processing system outputs a result of the linked packets.

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.

Various embodiments disclosed herein provide for a method for facilitating the exposure of raw data and packet metadata from a User Plane Function (UPF) of a core network to facilitate flexible data analysis of the raw data and packet metadata. Existing services that allow exposure of UPF data can be extended by defining a new event which allows UPF to expose raw data packet traces. A subscription request for data can be passed from a requesting network function (NF) to the UPF, and the subscription request can include an event indicator that indicates user plane data, a target User Equipment (UE) identifier, and an event filter. The UPF can then identify application traffic from a target UE that matches the subscription request, duplicate a subset of the user plane data packets from the application traffic, and then provide the requesting NF with the duplicated user plane data packets.

The present invention discloses a robust multi-label website fingerprint defense method based on hybrid deep learning, belonging to the field of network security technology. The present invention comprises two stages: reconstructing input sequences and constructing an anonymous sequence model. In the first stage, some overlapping virtual packet traces are first generated to the trainer adversary, making the trainer adversary familiar with the multi-tab overlapping traffic and website identities, thereby reducing the adversary's accuracy. Then, LSTM (long short-term memory) autoencoder technology is designed to effectively reconstruct the overlapping input sequences in the multi-tab interface and separate the overlapping regions. In the second stage, bidirectional long short-term memory (Bi-LSTM) is applied to anonymize the traffic sequence to blur the sequential pattern of user interactions. At the same time, adversarial examples are added during the training process to further improve the robustness of the method.

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.

In one example, a client-side packet is received from a client device by a processing system. From this, a client identifier is generated by the processing system based on the client device. In response, a modified client-side packet is generated by the processing system by modifying the client-side packet to include the client identifier. The modified client-side packet is transmitted by the processing system to a server system. A server-side packet is then received by the processing system from the server system.
