1. In a computer which is connected via a router to a computer network at a first location in the network for enabling the computer to transmit data to another location in the network, a method for controlling the transmission of said data comprising:

  • a) storing, by the computer, a number of addresses for respective ones of a plurality of;

    b) accessing the stored addresses by the computer to identify one of said routers;

    c) directing data to the identified router for the data to be transmitted to the other location;

    d) sensing, by the computer, failure of said transmission by the identified router;

    e) setting, by the computer, a transmission-failure indication recording a transmission failure by the identified router;

    f) identifying, responsive to the transmission failure, a next one of the routers, including the step of;

    accessing said stored addresses;

    g) checking, by the computer, whether such a transmission-failure indication has been previously set for the identified next one of the routers; and

    h) directing data to the identified next one of the routers for the data to be transmitted to the other location if the checking in step g) determines that no transmission-failure indication has been set.
