While video could be just one smaller chunk of site visitors traversing your network, its impact can't be overlooked. The identical switch and router products you employ for transmitting voice over IP are essential for video. In addition, you need Layer three QoS (DiffServ) and VLANs (virtual LANs).
Carrying Qualified video about IP networks has Distinctive problems compared to most non-time-critical IP targeted visitors. Numerous of those challenges are similar to Those people encountered in voice more than IP, but to a lot more stringent engineering necessities.
