Virtual-Player Type Break - Juniper MEDIA FLOW CONTROLLER 2.0.4 - ADMINISTRATOR S GUIDE AND CLI Administrator's Manual

Media Flow Controller Administrator's Guide
•
connection max-bandwidth
session bandwidth is between the AFR (Assured Flow Rate) and this value. Even if there
is available bandwidth in the link, Media Flow Controller does not allocate more than this
value for a session. When it is a full download, Media Flow Controller tries to allocate the
max-bandwidth to the session. Default is 0 (unbounded) with the Media Flow Controller
license, 200 kbps without it; you must have the license to change the unlicensed default.
In prefix mode, use no connection to reset the default.
•
fast-start
available bandwidth; in prefix mode, use no fast-start to disable (default is disabled).

the match query-string-parm hash value.

—Specify a string to implement MP4 or FLV seek (allows the client player to seek to
seek
a specific location of the URL). In prefix mode, use no seek to disable. Optionally:
•
seek-length query-string-parm
of data to send from the seek start position; referenced value must be in bytes.
•
enable-tunnel
this option needs to be selected only when the origin site changes their seek
mechanism. Default is disabled.

virtual-player type break

Use type break (formerly type 1) virtual players for Break® video delivery. Supports seek/
scrub for FLV videos using byte offsets and MP4 videos using time-offsets, fast-start, assured
flow, connection max-bandwidth, and authentication via hash. Use no virtual-player <name>
to delete. See
details.
