match query-string-parm <string>
seek query-string-parm <string> [enable-tunnel] [seek-length query-
string-parm <string>]
Notes:
•
assured-flow
—Set AFR for this virtual player, this assures that content is delivered at
least at the specified rate (but no more than the configured connection max-bandwidth)
for the session. Use virtual player <name> type break no assured-flow to re-disable, if
needed. By default, AFR is disabled (no delivery rate is assured). See
“Using Network
Connection Assured Flow” on page 72
for example.
•
auto
—Not supported in Release 2.0.4.
•
query-string-parm
—Specify a string; referenced value must be in kilobytes.
•
rate
—Define a static value, in kbps. A value of 0 (zero) means no throughput at all.
•
connection max-bandwidth
—Set the maximum bandwidth for a session. The actual
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 default.
•
fast-start
—Deliver the 1st set of kilobytes at either the maximum session speed or the
available bandwidth; in prefix mode, use no fast-start to disable (default is disabled).
•
query-string-parm
—Specify a string; referenced value must be in kilobytes.
•
size
—Define how many kilobytes should be expedited.
•
time
—Define how many seconds should be expedited.
•
hash-verify
—Verify the hash value specified in the URL (see
“Using hash-verify” on
page 76
for details); in prefix mode, use no hash-verify to disable.
•
digest
—Only md-5 is supported in Release 2.0.4.
•
match query-string-parm
—Specify a string indicating the provided hash value.
•
shared-secret {append | prefix}
—Enter a secret key that is then appended or
prefixed (as specified) to the URI, to calculate the hash which is then "matched" with
the corresponding configured match query-string-parm hash value.
•
seek
—Specify a string to implement FLV seek (allows the client player to seek to a
specific location of the URL); default is ec_seek.Use no seek to disable. Optionally:
•
seek-length query-string-parm
—Specify a string to signal the number of bytes
of data to send from the seek start position; referenced value must be in bytes.
•
enable-tunnel
—If set, all seek requests to the origin server are tunneled; typically
this option needs to be selected only when the origin site changes their seek
mechanism. Default is disabled.
virtual-player type qss-streamlet
Use type qss-streamlet (formerly type 2) virtual players to enforce assured-flow via rate
maps. Useful for Adaptive Bit Rate video delivery where the URI format signals the assured
flow rate. Use no virtual-player <name> to delete. In prefix mode, use no rate-map match
<string> to delete one particular entry. See
“Creating and Configuring Virtual Players (CLI)”
