CDN versions management¶
Some CDN features support depends on CDN version. Since build 5.3.447, a CDN version used by a CDN node may be explicitly set. This provides more flexible compatibility management: a newer WCS builds may be seamlessly integrated to a production CDN.
Node configuration¶
How the node should be advertised to other nodes¶
The supported CDN version may be explicitly set on the node by the following parameter (a current actual CDN version by default):
In this case, the node will communicate with other CDN nodes as CDN 2.7 node, so streams recording feature will be supported but stream replication feature will not.
What version the node should suppose other nodes to support¶
The node suppose other nodes to support the following version:
By default, the node suppose other node to be a lowest CDN 2.0 version. The supposition is kept until the actual version is received from other node (usually after the first successful signaling exchange).
