The introduction of IP TV may even further increase the usage on broad-
band access links for streaming video.
Current measurements of P2P traffic and forecasts for streaming video indi-
cate that voice traffic is (at present and will remain) a negligible component of
the overall traffic. Management of VoIP traffic, therefore, makes no sense,
except on bandwidth-starved portions of the Net or in private IP networks
where bandwidth is a premium (such as on networks using satellite links for
remote parts of the world, or for onboard networks of ships and airliners).
The emergence of video such as IP TV on cable and DSL, as well as various
video services in wireless networks, may change the mix of traffic types, but
only in the sense that more and more bandwidth will be required, in compari-
son to voice. Voice will, thus, continue to be a beneficiary of the proliferation of
broadband.Global Resonse Time (MS) : Past 30 Days
