computer industry. They are referred to within the Appellants’
specification as “page shipping” and “function shipping.” See
page 3 of Appellants’ specification. Each model is known in the
industry to have certain strengths and certain weaknesses. See
page 3 of Appellants’ specification. The two remote object
access models require programmers to write their programs
differently under each model. While the industry experts are
able to debate the respective strengths and weaknesses of each of
these remote object access mechanisms, the basic truth is that
the potential of distributed object computing will never be fully
realized without a remote access mechanism that maximizes the
benefits of each of the two models. See page 4 of Appellants’
specification.
Figure 4 shows a switch submechanism 415 within shipper 110.
The switch submechanism 415 is responsible for dynamically
switching between the page shipping model and the function
shipping model. See pages 14 and 15 of Appellants’
specification. Figures 11A and 11B show the switch processing of
the preferred embodiment. See page 25 of Appellants’
specification. Switch submechanism 415, which begins in block
1100 of figure 11A, runs periodically to determine whether the
system or network condition warrants a change to the object
