Abstract: The present disclosure describes a system, method, and computer program for dynamically reconciling a retailer receiving invoice with a distributor invoice for products sold and invoiced under multiple UPC codes and in multiple units of quantity. A retailer receiving invoice is matched to to a distributor invoice. For each line item in both invoices, the UPC, quantity, and unit-price are normalized. Invoiced UPCs are normalized to a hierarchy level in a product family a master product database. Also, invoiced unit prices are compared to upper and lower price limits for invoiced UPCs to determine whether an invoiced UPC correlates to an invoiced unit price. Quantity and unit-price are normalized by converting price-correlated units to base-level units in a product hierarchy. Normalized UPCs, quantities, and unit price are compared to match line items across invoices and discover any discrepancies. Credits are matched to discrepancies.

Abstract: Methods and systems for detecting an application associated with a given IP flow and differentially forwarding packets based on determined application are provided. According to one embodiment, an initial Internet Protocol (IP) packet of an IP flow is received by a network device. An application with which the initial IP packet is associated is determined by the network device. Based on the determined application, a forwarding rule to be applied to the initial IP packet is identified by the network device. Thereafter, the initial IP packet and subsequent IP packets associated with the IP flow are forwarded by the network device based on the identified forwarding rule.

Abstract: Systems and methods for an SDN switch that provides application-based conditional forwarding and session-aware load balancing are provided. According to one embodiment, a packet is received at an input port of a Software Defined Networking (SDN) switch. The packet is forwarded by the SDN switch to a first flow processing unit (FPU) of multiple FPUs of the SDN switch. The first FPU determines whether the packet is to be tracked. And, if so, the received packet is transmitted to a second FPU of the SDN switch; otherwise, the packet is transmitted to a third FPU of the SDN switch. When the packet is received at the second FPU, the packet is conditionally forwarded by the SDN switch to an application device. When the packet is received at the third FPU, the packet is conditionally forwarded to an output port or dropped.

When forwarded to the second FPU, the packet is processed based on a second set of rules by forwarding it to a second security device or dropping it or forwarding it to the egress port. When forwarded to the second security device, the packet is security processed, including dropping it or forwarding it to the egress port or conditionally forwarding it to a third FPU to be sequentially forwarded to a third security device.

Abstract: A method for balancing load among firewall security devices (FSDs) is provided. According to one embodiment, a switching device performs adaptive load balancing among cluster units of an HA cluster of firewall security devices. A load balancing (LB) function implemented by the switching device is configured based on information received from a network administrator. A LB table is maintained that forms associations between hash values output by the LB function and corresponding ports of the switching device to which the cluster units are coupled. Network traffic received by the switching device is directed to appropriate cluster units based on the LB function and the LB table. A traffic load on each of the cluster units is monitored. Responsive to a deviation from a predefined ideal traffic distribution, an attempt is made to improve performance of the HA cluster by dynamically adjusting the LB balancing table to address the deviation.

Security services for subsequently received network traffic associated with the traffic sessions is performed by the second cluster unit.

Abstract: In a method of eddy current testing via an eddy current testing instrument, in response to the eddy current test instrument experiencing acceleration, the eddy current test instrument outputs an alternating magnetic field which induces eddy currents in a specimen and detects the induced eddy currents. When the eddy current test instrument is not experiencing acceleration, after a delay, the eddy current test instrument withholds outputting the alternating magnetic field to, thereby, conserve power.
