  • Correlating network flows in a routing service for full-proxy network appliances
    Patent number: 11088948
    Abstract: Systems and methods are provided to add flow identification information to packets of network traffic. Each packet can have flow identification information added based on the packet being sent to a full-proxy mode appliance. A stateful network routing service may intercept packets and determine the packets are to be sent to a full-proxy mode appliance. Based on this determination, the stateful network routing service may obtain or generate flow identification information to identify the packet. The stateful network routing service may add the information to the packet and transmit the enriched packet to a full-proxy mode network appliance. The stateful network routing service may receive a second enriched packet from the network appliance. The stateful network routing service can parse the second enriched packet for flow identification information and identify the second enriched packet based on the flow identification information.

  • Phosphorus-containing flame retardants
    Patent number: 8895648
    Abstract: A flame-retardant resin composition comprises a base resin (A), such as a polyester, polyamide or polycarbonate resin, and an organophosphorus compound (B) having at least one of the following formulas (I), (II) and (III): where A is selected from O, S, SO2, a single bond, alkyl, and —CH2—P1; P1 is a phosphorus-containing group of the formula: R1 and R2 are the same or different and each is selected from H, O-alkyl, O-aryl, alkyl, aryl, and OM; R3 is H or alkyl; M=Na, K, Zn, Al, Ca; a is an integer from 0 to 4, provided that a is at least 1 unit for each polymer chain; n is an integer from 1 to 100,000 and m is an integer from 0 to 100,000.
