Media Flow Controller Configuration Tasks (CLI)
5.
Optionally, configure connection max-bandwidth delivery optimization. Default is 0
(unbounded) with the Media Flow Controller license, 200 kbps without it; you must have
the license to change the unlicensed default. Use no connection to reset default.
connection max-bandwidth {0 | <kbps>}
6.
Optionally, configure fast-start delivery optimization.
fast-start {query-string-parm <string> | size <KB> | time <seconds>}
7.
Optionally, configure seek delivery optimization specifying a query param for when seek
should start and how long it should last. Query params must be used.
seek query-string-parm <string> [seek-length query-string-parm <string>]
8.
Optionally, configure smooth-flow delivery optimization. A query param must be used.
See
“Media Flow Controller SmoothFlow” on page 51
for detailed descriptions.
smooth-flow query-string-parm <string>
9.
Type exit to leave virtual-player configuration mode.
Example:
test-vos (config) #
virtual-player test type generic
test-vos (config virtual-player test) #
hash-verify digest md-5 match
query-string-parm h shared-secret zpzp prefix
test-vos (config virtual-player test) #
assured-flow query-string-parm afr
test-vos (config virtual-player test) #
full-download always
test-vos (config virtual-player test) #
connection max-bandwidth 0
test-vos (config virtual-player test) #
fast-start time 90
test-vos (config virtual-player test) #
seek query-string-parm sk
test-vos (config virtual-player test) #
smooth-flow query-string-parm sf
test-vos (config virtual-player test) #
exit
test-vos (config) #
10. Verify configurations with show virtual-player <name>.
Creating and Configuring Server-Maps (CLI)
Media Flow Controller server-map allows you to define the origin server or servers to which
Media Flow Controller goes in case of a cache-miss. To use this feature, you define an XML
file with the origin server parameters, such as host, protocol, and port number, described in
detail in
Chapter 7, “Server Map Configuration,”
. After the file is defined, you set parameters,
including the file-url (which is immediately validated) using the server-map command and,
finally, you add the server-map to a configured namespace. See
Chapter 7, “Server Map
Configuration,”
for XML file formatting. See
server-map
for CLI details.

Using server-map to Create a Consistent Hash Cluster
The cluster-map server map lets you to define a consistent hashing scheme to bind objects to
nodes. See
“Consistent Hash-Based Clustering and Origin Escalation” on page 48
