LDAP is a widespread standard database format which stores network
users. The format is hierarchical, where nodes are often represented
asbranch location > department > sub-department, orexecutives >
managers > staff members. The database standard is employed by most
user directories including Microsoft Active Directory. H.350 is an extension
to the LDAP standard for the videoconferencing industry.
Scopia Desktop's lecture mode allows the participant defined as the lecturer
to see all the participants, while they see only the lecturer. All participants
are muted except the lecturer, unless a participant asks permission to
speak and is unmuted by the lecturer. This mode is tailored for distance
learning, but you can also use it for other purposes like when an executive
addresses employees during company-wide gatherings.
Legacy endpoints are H.323–based endpoints that might or might not
support H.460.
A load balancer groups together a set (or cluster) of servers to give them a
single IP address, known as a virtual IP address. It distributes client service
requests amongst a group of servers. It distributes loads according to
different criteria such as bandwidth, CPU usage, or cyclic (round robin).
Load balancers are also known as application delivery controllers (ADC).
A location is a physical space (building) or a network (subnet) where video
devices can share a single set of addresses. A distributed deployment
places these components in different locations, often connected via a VPN.
Management refers to the administration messages sent between
components of the Equinox Solution as they manage and synchronize data
between them. Management also includes front-end browser interfaces
configuring server settings on the server. Management messages are
usually transmitted via protocols like HTTP, SNMP, FTP or XML. For
example, Equinox Management uses management messages to monitor
the activities of an MCU/Media Server, or when it authorizes the MCU/
Media Server to allow a call to proceed.
Megabytes per second (MBps) is a unit of measure for the bitrate. The
bitrate is normally quoted as kilobits per second (kbps) and then converted
by dividing it by eight to reach the number of kilobytes per second (KBps)
and then by a further 1000 to calculate the MBps.
An MCU, or Multipoint Control Unit, connects several endpoints to a single
videoconference. It manages the audio mixing and creates the video
layouts, adjusting the output to suit each endpoint's capabilities.
See Meeting Type on page 91.
Media refers to the live audio, video and shared data streams sent during a
call. Presentation and Far end camera control (FECC) are examples of
