  • Optimizing transfer of fragmented packetized data
    Patent number: 10313486
    Abstract: The present invention increases the efficiency of transmitting data from a plurality of fragmented internet protocol (IP) packets over a computer network. After receiving a plurality of fragmented packets over a computer network interface a computing device may reassemble data from the plurality of packets into an IP packet that includes data from each of the fragmented IP packets. The reassembled IP packet may then be compressed and encrypted before being transmitted to a computer identified in a destination address in each of the plurality of fragmented packets.

  • METHOD FOR EFFECTIVE PMTU DISCOVERY IN VPN ENVIRONMENT
    Publication number: 20190007915
    Abstract: Methods are directed towards initializing a path maximum transmission unit value for two gateways in communication via a network tunnel (e.g., VPN environment). The initialized path maximum transmission unit value is used in establishing the network tunnel of the two gateways. Methods are also directed towards synchronizing path maximum transmission unit values for the two gateways after the network tunnel has been established. These methods minimize the occurrence of dropped data packets arising from mismatched path maximum transmission unit value between the gateways.
