We agree. The system disclosed by Drake does ensure adequate QOS for each
represented data stream. In addition, the attributes of Drake are used for determining
bandwidth control for a particular data stream having a unique ID to the extent that a
determination is made as to whether the components of the selected path satisfy the
QOS values for a multimedia transmission (col. 2, lines 36-41). Further, Drake
discloses that bandwidth management can also be called QOS management (col. 1,
lines 55-57). However, in Drake, the overall function of allocator 20 is to is to receive
the QOS request from source station 10, examine the resources of LAN 17 and
determine if a path exists between the source station 10 and target station 29 which
satisfies the QOS (col. 2, lines 50-55).
From our review of Drake, we find that the reference to the desired multimedia
transmission is a reference to the media stream for the multi-media call. Drake does
not conduct the multimedia call by using multiple-media streams for the call, as does
appellants (specification, page 6). Nor does Drake allocate the reserved call level
bandwidth to individual media streams of the multi-media call, as does appellants
(specification, page 8). Accordingly, while we agree with the examiner (answer,
page 8) that in Drake, an individual data stream among existing data streams in the
transmission path requests a new bandwidth allocation (such as when changing from a
one way client/server cal to a two-way client/client call), and that QOS is implemented
on the individual data stream after examining and identifying the Stream ID, Drake does
