    Abstract: The present invention relates to a method and apparatus for controlling a handshake operation. Datagram Transport Layer Security (DTLS) is an important secure protocol in the IP based Internet of things The performance of DTLS handshake can be significantly affected by network status, traffic and packet loss rate, etc. It is therefore suggested evaluating a package loss rate and estimating causes of packet loss. Then, a DTLS handshake strategy may be changed adaptively based on the detection of packet loss and network status. As a result, the successful rate and delay of DTLS handshake can be improved. An acknowledgement and a non-acknowledgement mode may be used in a hybrid way to evaluate the package loss rate and estimate causes of packet loss and eventually improve performance of DTLS handshake.

    Abstract: An apparatus and method for enhancing the infrastructure of a network such as the Internet is disclosed. A packet interceptor/processor apparatus is coupled with the network so as to be able to intercept and process packets flowing over the network. Further, the apparatus provides external connectivity to other devices that wish to intercept packets as well. The apparatus applies one or more rules to the intercepted packets which execute one or more functions on a dynamically specified portion of the packet and take one or more actions with the packets. The apparatus is capable of analyzing any portion of the packet including the header and payload. Actions include releasing the packet unmodified, deleting the packet, modifying the packet, logging/storing information about the packet or forwarding the packet to an external device for subsequent processing. Further, the rules may be dynamically modified by the external devices.

    Abstract: A data interaction method is provided, which includes: sending simultaneously an address detection request for a UDP channel and an address detection request for a TCP channel; and when both address detection for the UDP channel and address detection for the TCP channel fail, sending an address detection request for an HTTP channel; when detection of at least one channel succeeds, collecting two types of addresses corresponding to each channel in the at least one channel; performing address exchange and address matching with a peer client host; and performing channel connectivity detection based on matched addresses, and selecting a channel with a highest priority from channels on which connectivity detection is successful for data interaction with the peer client host. Therefore, efficiency of traversing a NAT host during address detection is improved.

    Abstract: A TCP/IP packet decoder fetches, from a packet received via a satellite communication system, IP version information, which is provided to version comparators. When a version comparator indicates a match, protocol information is provided to a TCP comparator. If the TCP comparator determines that the packet is a TCP data packet, a flag is raised causing generation of a TCP acknowledgment for transmission to a source device. In another embodiment, a layer 3 switch or router includes a TCP hardware filter to determine whether the received packet is a TCP data packet, thereby causing the TCP data packet to be mirrored for transmission to a modem. In a third embodiment, a TCP hardware filter, provides an indication to a layer 2 switch when a TCP data packet is received causing the TCP data packet to be mirrored for transmission to a modem, which generates and transmits a TCP acknowledgment.
