Physical separation of traffic on common protocols seems most likely. We asked respondents which of three
network architecture scenarios they predicted would happen within five years: common protocols and
switches, common protocols on separate physical switches, and separate protocols and switches
(nonconvergence). The most popular selection is the middle ground, of common protocols but physical
traffic separation (see Figure 10). Of the 76% of respondents that indicated an interest in convergence, a
slight majority (55%) indicated a preference for separate networks. This indicates an interest in
convergence, but some desire for a conservative approach to it. Physical separation provides less benefit,
but appears to be seen as having less risk and complexity as well, which seems to resonate with
respondents at least for the moment.
