Server Map Overview

Media Flow Controller can use an XML file to specify various origin fetch schemes; the XML
file can reside in an external server. The format types and syntax for the XML files that the
server-map command provides access to are described in this chapter. After you define the
XML file, then go to the Media Flow Controller CLI for
server <protocol> server-map option with the format-type and file URL of the XML mapping
file that you defined. This chapter covers these topics:

Server Map Format Types

Media Flow Controller provides three different server-map format-type options and a fourth
for NFS that requires you to leave the format-type unspecified:
•
host-origin-map
The XML file performs a hash matching the Host header to an origin server/port defined in
the file. You cannot use another server-map with this format-type.
•
cluster-map
in a cluster configuration. You can use this format-type with the origin-escalation-map
to create a server map hierarchy, or you can use this map alone.
•
origin-escalation-map
servers which are logically viewed as one. Requests are sequentially initiated to specific
origin servers based on a configured weight, until the request is satisfied or all available
origin servers have been tried. You can use this format-type with cluster-map to create a
server map hierarchy, or you can use this map alone.
•
nfs-map—Provides a way to configure multiple NFS publishing points for origin. You
cannot use another server-map with this format-type.
Note! For cluster-map and origin-escalation-map only, you can use as many, and in any
combination, together or separately, as needed.
