    Abstract: Techniques and architecture are described for L2 service insertion in a network. More particularly, the techniques and architecture provide for monitoring a L2 service, e.g., firewall, MAC address (instead of learning the MAC address) and registering/de-registering the service node (e.g., fabric border or edge or LISP service_etr) to the service control plane (e.g., LISP MSMR) based on this. This not only load-balances the traffic (per L2 flow) but also tracks it for node's liveliness. The techniques and architecture also provide L2 service insertion connected to a service border to allow for dynamic SGT based service, e.g., firewall, insertion for both software defined access (SDA) fabric and non-fabric deployments.

    Abstract: A method for identifying one or more weakness in a network system through simulations includes configuring a plurality of chaos events to be run on the network system, running the plurality of chaos events on the network system, receiving alert messages from a monitoring system, determining differences if the alert messages match with a set of expected alert messages and/or delay in receiving the alert messages, and reporting the determined differences to a control plane of the network system for display on a user terminal.

    IPC: H04B17/318

    Abstract: In one aspect, a system includes a station device configured to transmit a signal; multiple access point devices in connection with the station device, the multiple access point devices configured to receive the signal transmitted from the station device, wherein the multiple access point devices are configured to convert the signal into a measurable form; and a processing unit operably connected to the multiple access point devices. The processing unit is configured to, for each subcarrier within the signal received by the multiple access point devices, determine a measurement of channel state information including an overall shape of the signal; determine a magnitude distance for each subcarrier; and determine a location of the station device based on a fit of the magnitude distance to a model, wherein the model is based on an environment with one or more obstacles causing an obscuration of the signal.

    Abstract: Systems, apparatuses, and methods for wireless communications are provided. A method may comprise receiving, by a wireless device from a base station, one or more messages comprising downlink control information (DCI) associated with a DCI format; determining that a first field of the DC corresponds to a predefined value, determining that, based on the first field corresponding to the predefined value, the DCI is for a random access procedure associated with a physical downlink control channel (PDCCH) order; determining, based on the determining that the DCI is for a random access procedure associated with a PDCCH order and based on a plurality of fields of the DCI, a random access channel (RACH) occasion; and transmitting, based on the RACH occasion, a random access preamble.

    Abstract: Energy-aware configurations can be utilized to operate a network based on sustainability-related metrics. In many embodiments, a suitable device includes a processor, a memory commutatively coupled to the processor, a plurality of elements, a communication port, and an energy-aware topology logic configured to collect topology data from one or more network devices, wherein each of the one or more network devices include a plurality of elements. The energy-aware topology logic can receive power source data and power usage data related to plurality of elements and generate an element energy coefficient (EEC) for a plurality of elements. Subsequently, the energy-aware topology logic can also generate an energy-aware configuration for at least one of the one or more network devices, and then pass the generated energy-aware configuration to the at least one network device, wherein the energy-aware configuration is configured to steer traffic based on at least one sustainability-related metric.

    Abstract: This disclosure describes various methods, systems, and devices related to identifying path changes of data flows in a network. An example method includes receiving, at a node, a packet including a first signature. The method further includes generating a second signature by inputting the first signature and one or more node details into a hash function. The method includes replacing the first signature with the second signature in the packet. The packet including the second value is forwarded by the node.
