Appeal No. 1997-0895
Application 08/286,107
Hedberg:
The software run by the host computer needs
minimal changes to adapt to the network. Routing,
connections, synchronization, network management and
network protocol processing are handled by the
crossbar interface 11 or 12 rather than by the host.
Communications between crossbar interfaces 11 and 12
are handled by sub-network protocols running among
crossbar interfaces; the host computers 13 and 14 do
not directly participate in sub-network
transmissions. Standard host network protocols and
messages communicate “on top of” the underlying
network provided by the crossbar interfaces and
crossbar switch. Applications and network layers
running on the host computers communicate with their
peer layers running on other hosts within the
network, unaware of the activity of the crossbar
interfaces and crossbar switching. (Column 5, lines
13-28.) (Emphasis added.)
As pointed out above, Hedberg teaches the
obviousness of using components of different composition
(e.g., fiber optic), and uses different protocols, or at least
protocol layers. Thus, we will sustain the Examiner’s
rejection of claim 26. Likewise, since all claims stand or
fall together, we will sustain the Examiner’s rejection of
claims 34 and 49 through 66.
In view of the foregoing, the decision of the
Examiner rejecting claims 26, 34 and 49 through 66 under 35
