What is a video bridge, gateway and gatekeeper?
A video bridge also known as a “Multipoint Control Unit” (MCU), is a network component that allows members to schedule a multi-point call when three or more sites wish to hold a videoconference. A gateway is a network component that provides the protocol translation between differing end point conference protocols (i.e., H.323 to H.320). A gatekeeper is a network component that provides Call Admission Control and translation services of an end point (i.e.-IP addresses to E.164 IDs). A gatekeeper can also deny access or limit the number of simultaneous connections to prevent network congestion.
