  • Patent number: 9531590
    Abstract: Some embodiments provide an elastic architecture for providing a service in a computing system. To perform a service on the data messages, the service architecture uses a service node (SN) group that includes one primary service node (PSN) and zero or more secondary service nodes (SSNs). The service can be performed on a data message by either the PSN or one of the SSN. However, in addition to performing the service, the PSN also performs a load balancing operation that assesses the load on each service node (i.e., on the PSN or each SSN), and based on this assessment, has the data messages distributed to the service node(s) in its SN group. Based on the assessed load, the PSN in some embodiments also has one or more SSNs added to or removed from its SN group. To add or remove an SSN to or from the service node group, the PSN in some embodiments directs a set of controllers to add (e.g., instantiate or allocate) or remove the SSN to or from the SN group.

  • Patent number: 9407499
    Abstract: An enhanced bypass mode simulcast radio communication system (200) includes a plurality of transmit/receive (T/R) sites (2101, 2102, 2103) configured to participate in a simulcasting communication session responsive to a control point system (201). A site controller (211) is responsive to determination of a timing malfunction at a first one of the T/R sites. In response, the site controller is configured to automatically terminate participation of the malfunctioning T/R site in the simulcasting communication session and perform further actions to cause the malfunctioning site to transition to a multisite mode of operation involving a network switching center (202). The simulcast system automatically adjusts its site timing to compensate for the loss of the T/R site in bypass.

  • Patent number: 9300586
    Abstract: A method for load balancing traffic from controller to destination access point (AP) via switch across multiple physical ports starts with controller receiving a packet from a source client device that is destined for destination client device associated with destination AP. The controller may select, based on an identifier associated with source or destination client device, a first or a second controller IP address. Controller may encapsulate the packet to generate an encapsulated packet including an outer header that includes the selected controller IP address. Controller may transmit the encapsulated packet to the switch that may distribute traffic to destination AP across multiple physical ports based on the selected controller IP address. Controller may also select a destination port based on destination client device of a packet and may encapsulate the packet using CAPWAP to generate an encapsulated packet including the destination port in a header of the encapsulated packet.

  • Patent number: 9288161
    Abstract: Verifying the functionality of an integrated circuit, the integrated circuit being operable for processing a data packet thereby generating a data processing result. A data packet to be processed is evaluated to determine if the data packet is an erroneous data packet. If the data packet is identified as an erroneous data packet, a modified data packet is generated by modifying the erroneous data packet and providing the modified data packet to the integrated circuit. A determination is made as to whether the data processing result comprises the modification; and a malfunction of the integrated circuit is signaled, if the data processing result comprises the modification.

  • Patent number: 9277452
    Abstract: Adaptive modulation and priority-based flow control in wireless communications are disclosed. Ingress communication traffic is modulated for transmission over a wireless communication link. A modulation rate of modulation to be applied to the ingress communication traffic is controlled by adaptive modulation. A rate at which the ingress communication traffic is received is controlled through Priority-based Flow Control (PFC), but the PFC is based on the adaptive modulation. Adaptive modulation and PFC are thus linked together. PFC messaging could be sent when a change in modulation rate due to the adaptive modulation would not meet the rate at which the ingress communication traffic is received. If a change in modulation rate due to the adaptive modulation would still meet the rate at which the ingress communication traffic is received, then PFC messaging might not be sent.

A device may receive a request to allocate resources for a packet flow, the resources being allocated at a number of network devices. The device may select, in response to the request, a set of queues that includes a queue selected at each of the network devices, the selected queue, at each of the network devices, being associated with a maximum latency period. The device may transmit one or more messages, to the network devices, indicating that the selected set of queues are to be used for buffering of the packet flow during packet scheduling.
