Abstract: An extension is provided to the SEND protocol without requiring a CGA or third party trust anchor. A shared key is provided to both a sender and receiver of a neighbor discovery (ND) message. A digital signature option is contained in the ND message. A digital signature field is determined by the algorithm field in the option. When the ND message is received, the receiver may verify the digital signature field using the pre-shared key according to the algorithm field. If the ND message passes verification, the receiver may process the message.

Abstract: Methods and systems are provided for detecting dead tunnels associated with a VPN. An indicator of a tunnel capability, for example, a DPD vendor ID, is received from a peer through a VPN connection. The tunnel capability is associated with one or more phase II tunnels associated with the VPN. Traffic generated by the peer is detected, and if traffic is detected at a tunnel, the tunnel is presumed to be alive. When no traffic is detected in a tunnel, a DPD packet exchange with the tunnel is initiated. A determination is made, based on the packet exchange, whether the tunnel is alive.

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.

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.
Abstract translation: 本发明通过计算机网络提高从多个分段的因特网协议（IP）分组传输数据的效率。 在计算机网络接口上接收到多个分段分组之后，计算设备可以将来自多个分组的数据重新组合成包括来自每个分段IP分组的数据的IP分组。 然后可以在重新组装的IP分组被发送到在多个分段分组中的每一个中的目的地地址中标识的计算机之后进行压缩和加密。
