Creating And Configuring Server-Maps (Cli); Using Server-Map To Create A Consistent Hash Cluster - Juniper MEDIA FLOW CONTROLLER 2.0.4 - ADMINISTRATOR S GUIDE AND CLI Administrator's Manual

Media Flow Controller Administrator's Guide
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
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
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
