1. A method for facilitating testing a network node apparatus, comprising the following steps:

  • (a) establishing a plurality of switched virtual circuits between a first machine having a first high level address and a second machine having a second high level address; and

    , (b) sending a first message from the first machine to the second machine, including the following substeps;

    (b.1) constructing the first message to have a source identification equal to the first high level address and a destination identification equal to a first virtual address for the second machine, (b.2) sending the first message to the second machine over a first switched virtual circuit associated with the first virtual address, including the following substeps;

    (b.2.1) replacing the source identification with a first virtual address for the first machine, and (b.2.2) replacing the destination identification with the second high level address.
