20140126367NETWORK APPLIANCE THAT DETERMINES WHAT PROCESSOR TO SEND A FUTURE PACKET TO BASED ON A PREDICTED FUTURE ARRIVAL TIME - A network appliance includes a network processor and several processing units. Packets a flow pair are received onto the network appliance. Without performing deep packet inspection on any packet of the flow pair, the network processor analyzes the flows, estimates therefrom the application protocol used, and determines a predicted future time when the next packet will likely be received. The network processor determines to send the next packet to a selected one of the processing units based in part on the predicted future time. In some cases, the network processor causes a cache of the selected processing unit to be preloaded shortly before the predicted future time. When the next packet is actually received, the packet is directed to the selected processing unit. In this way, packets are directed to processing units within the network appliance based on predicted future packet arrival times without the use of deep packet inspection.05-08-2014
20140133320INTER-PACKET INTERVAL PREDICTION LEARNING ALGORITHM - An appliance receives packets that are part of a flow pair, each packet sharing an application protocol. The appliance determines the application protocol of the packets by performing deep packet inspection (DPI) on the packets. Packet sizes are measured and converted into packet size states. Packet size states, packet sequence numbers, and packet flow directions are used to create an application protocol estimation table (APET). The APET is used during normal operation to estimate the application protocol of a flow pair without performing time consuming DPI. The appliance then determines inter-packet intervals between received packets. The inter-packet intervals are converted into inter-packet interval states. The inter-packet interval states and packet sequence numbers are used to create an inter-packet interval prediction table. The appliance then stores an inter-packet interval prediction table for each application protocol. The inter-packet interval prediction table is used during operation to predict the inter-packet interval between packets.05-15-2014
20140233394PACKET PREDICTION IN A MULTI-PROTOCOL LABEL SWITCHING NETWORK USING OPENFLOW MESSAGING - A first switch in a MPLS network receives a plurality of packets. The plurality of packets are part of a pair of flows. The first switch performs a packet prediction learning algorithm on the first plurality of packets and generates packet prediction information. The first switch communicates the packet prediction information to a Network Operation Center (NOC). In response, the NOC communicates the packet prediction information to a second switch within the MPLS network utilizing OpenFlow messaging. In a first example, the NOC communicates a packet prediction control signal to the second switch. In a second example, a packet prediction control signal is not communicated. In the first example, based on the packet prediction control signal, the second switch determines if it will utilize the packet prediction information. In the second example, the second switch independently determines if the packet prediction information is to be used.08-21-2014
20140236873PACKET PREDICTION IN A MULTI-PROTOCOL LABEL SWITCHING NETWORK USING OPERATION, ADMINISTRATION, AND MAINTENANCE (OAM) MESSAGING - A first switch in a MPLS network receives a plurality of packets that are part of a pair of flows. The first switch performs a packet prediction learning algorithm on the first plurality of packets and generates packet prediction information that is communicated to a second switch within the MPLS network utilizing an Operations, Administration, and Maintenance (OAM) packet (message). In a first example, the first switch communicates a packet prediction information notification to a Network Operations Center (NOC) that in response communicates a packet prediction control signal to the second switch. In a second example, the first switch does not communicate a packet prediction information notification. In the first example, the second switch utilizes the packet prediction control signal to determine if the packet prediction information is to be utilized. In the second example, second switch independently determines if the packet prediction information is to be used.08-21-2014

20140136683INTER-PACKET INTERVAL PREDICTION OPERATING ALGORITHM - An appliance receives packets that are part of a flow pair, each packet sharing an application protocol. The appliance determines an estimated application protocol of the packets without performing deep packet inspection on any packets. The estimated application protocol may be determined by using an application protocol estimation table. The appliance then predicts the inter-packet interval between a packet previously received by the appliance and a next packet not yet received by the appliance. The inter-packet interval may be determined by using an inter-packet interval prediction table. The appliance then preloads packet flow data in a cache before the next packet is predicted to arrive at the appliance. Upon receiving the next packet, the packet flow data is preloaded in the cache. This reduces packet processing time by removing waiting periods previously required to cache packet flow data from an external memory after receiving the next packet.05-15-2014

20140371830SYSTEM THAT SECURES AN ELECTRODE ARRAY TO THE SPINAL CORD FOR TREATING BACK PAIN - This invention provides a device for implantation directly into the spinal cord for the purpose of treating back pain. Electrodes on a backing that conforms directly to the spinal cord are installed as a source of electrical stimulation and pain relief. The electrode array is maintained on the spinal cord at a chosen location by way of a spring or support structure that is anchored to an anatomical structure outside the spinal cord but near the site of implantation. Suitable anchoring structures include the vertebrae and the dura. Secured in this fashion, the support structure maintains a gentle pressure of the electrode array against the spinal cord so as to stay in electrical contact but minimize injury or inflammation. The device may accommodate and buffer movement of the spinal cord both laterally and in a caudal-rostral fashion so that the electrode array remains in place.12-18-2014
