Bionic Buffalo Tech Note #108: DSM-CC Data Carousel and Module Identification
A client listening to this sequence, and operating by comparing the current
with that from the previous message, will operate correctly, although it will do extra work by
messages it has already seen. (Although, over time, the
three subsets have not changed, each message's
is different from that of the
previous message.) To operate more efficiently, Bionic Buffalo's
download client caches

they were sent several messages previously.

distinguish them from one another. It sees them as a single carousel.
The primary use for these composite carousels is that of convenience for the server application, which
may load or otherwise manage their contents separately. For example, one
may be used for
ordinary content, with another activated only for special content. The ordinary carousel will operate
independently of the special carousel, subject to overall bandwidth limitations.
