  • Patent number: 6618359
    Abstract: A method, translating apparatus, apparatus comprising a computer readable medium, and system for error recovery in a mixed protocol communication network includes a translation function that communicates with a first device using a first communication protocol and a second device using a second communication protocol. When the translation function determines that a connection failure occurred between the translation function and the second device, the translation function completes a first link reset procedure with the first device to suspend data flow between the first device and the translation function, completes a connection establishment procedure with the second device to establish a connection between the translation function and the second device, and then completes a second link reset procedure with the first device to enable data flow between the first device and the translation function.

  • Patent number: 6320874
    Abstract: A method, translating apparatus, apparatus comprising a computer readable medium, and system for establishing and terminating an end-to-end connection in a mixed protocol communication network includes a translation function that communicates with a first device using a first communication protocol and a second device using a second communication protocol. In order to establish an end-to-end connection, the translation function receives a first control message from the second device initiating a connection between the second device and the translation function, completes a connection establishment procedure with the second device, receives a first data message from the second device, and transmits a second data message to the first device.

  • Patent number: 6311222
    Abstract: An apparatus for translating a message between a first transmission protocol to a second transmission protocol limits buffer sizes for storing incoming and outcoming message data. To that end, each message has a message size that is no larger than a maximum message size, and the first protocol transports message data with message envelopes having an envelope size that is no larger than a maximum envelope size. The apparatus further includes a first protocol interface for interfacing with first protocol devices that communicate via the first protocol, a second protocol interface for interfacing with second protocol devices that communicate via the second protocol, and control logic that couples the first protocol interface with the second protocol interface.

In order to establish an end-to-end connection, the translation function receives a first data message from the first device, establishes a connection with the second device, and transmits a second data message to the second device. In order to terminate an end-to-end connection, the translation function receives a reset message from the first device, terminates the connection with the second device, and transmits a reset confirmation message to the first device.
