  • Patent number: 11689544
    Abstract: Intrusion detection systems and methods monitor legal control messages in an operational control system to detect subtly malicious sequences of control messages with undesirable emergent effects on devices in the operational control system. A message provenance component may investigate system-level correlations between messages rather than detecting if individual messages are anomalous. A semantic fuzzing component may search, based on the operational effect of candidate message sequences, the space of legal messages for sequences that cause actual harm. Behavior oracles may be used to test message sequences to identify sequences that induce drift towards a failure state. The intrusion detection system is able to prevent harm and disruption arising from control messages that individually appear legitimate and benign but that, in combination with other messages, can cause undesirable outcomes.

If a rendering machine fails then the partially available GOP from that rendering machine is discarded and another rendering machine, having the capacity to handle the GOPs stream, is activated. It provides GOPS from the failed GOP onwards and rendering continues therefrom by the replacing rendering machine. Rendering initially at a faster than real-time speed it is possible to catch-up on time so that the edge server continues to receive and transmit the GOPs without interruption. A plurality of rendering machines continuously operate to feed the edge server(s) and the number of channels used is such that allows for sufficient redundancy as well as for the faster than real-time rendering that is necessary in the case of a need for failover.

    Abstract: Techniques for controlling packet flows are described. In an example, a packet is sent on a virtual network. The packet's header includes scoping data that indicates a network boundary within which the packet is permitted and/or prohibited to flow. A network virtualization device of a substrate network receives the packet. The network virtualization device determines the scoping data from the header and, based on network configuration information, determines the forward flow of the packet. If the forward flow falls within a permitted network boundary indicated by the scoping data, the network virtualization device sends the packet forward. Otherwise, the packet is dropped.

A multi-AP controller may determine a BSS configuration policy (such as a maximum transmission opportunity (TXOP) duration) for the second BSS based on a type of traffic in the first BSS. This disclosure includes techniques for sharing traffic characteristics, determining the BSS configuration policy, communicating the BSS configuration policy, and controlling the BSS configuration policies for multiple BSSs so that one of the BSSs can provide a quality of service (QoS) for one or more stations (STAs).

  • Patent number: 11652752
    Abstract: A network device adds a fixed value to a congestion threshold (CT) when a first period ends. Detects whether a difference obtained by subtracting average traffic load of a queue in the first period from average traffic load of the queue in a second period is greater than a target increase value, sets the CT based on a detection result when the second period ends, where the first period is previous to the second period; marks a received packet when a quantity of packets buffered in the queue is greater than the CT, enqueues the marked packet and sends the marked packet to a receiving device.

  • Patent number: 11652791
    Abstract: Systems, methods, and computer-readable media for implementing an extranet policy include receiving a request from a source to perform a lookup for a destination address. A lookup for the destination address is performed in a consolidated routing table, the consolidated routing table including a consolidated mapping of address prefixes associated with two or more virtual networks. If the lookup results in a match for the destination address with a matching address prefix, a matching virtual network associated with the matching address prefix is determined. An access policy for the request corresponding to the matching virtual network is obtained, and based on the access policy the request is allowed to access the destination address in the matching virtual network or disallowed. The consolidated routing table can be implemented in a mapping server using a Locator/ID Separation Protocol (LISP).

  • Patent number: 11652750
    Abstract: Packet-switching operations in a network device are managed based on the detection of excessive-rate traffic flows. A network device receives a data unit, determines the traffic flow to which the data unit belongs, and updates flow tracking information for that flow. The network device utilizes the tracking information to determine when a rate at which the network device is receiving data belonging to the flow exceeds an excessive-rate threshold and is thus an excessive-rate flow. The network device may enable one or more excessive-rate policies on an excessive-rate traffic flow. Such a policy may include any number of features that affect how the device handles data units belonging to the flow, such as excessive-rate notification, differentiated discard, differentiated congestion notification, and reprioritization. Memory and other resource optimizations for such flow tracking and management are also described.

  • Patent number: 11646957
    Abstract: Technologies are provided for analyzing packet loss in network packet streams using windowed loss durations. A computing device can be configured to detect a first loss period in a network packet stream and a second, subsequent loss period in the network packet stream. The computing device can determine a number of packets received in the stream between the two loss periods, and can compare this number of packets to a specified recovery window length. If the number of packets received between the two loss periods is less than the recovery window length, then the computing device can treat the two loss periods, and the packets received between the two loss periods, as a single period of packet loss. The packet loss period can be treated as a single loss event for the purposes of analyzing network packet stream quality of experience and/or tuning packet loss compensation mechanisms.
