Which means the sender will send one packet and wait for a response before sending another packet. As with call signaling and media processing, more latency has an overall negative impact on performance. The first factor is the round trip time or overall network latency between the requesting endpoint and the TFTP server. While consideration on server performance capabilities should come into play, the network plays a huge role in actual performance. The basic idea is that each client requesting a firmware file takes up a TFTP session. The Cisco SRND for Cisco Unified Communications 7.0 provides a solid discussion on what type of performance can be expected using the TFTP protocol. DBLNotify informs the TFTP service of changed record information Notify process informs all CUCM nodes to reset the record instanceĤ. Database information is replicated to all cluster nodesģ. DBL writes configuration data to the database on publisher nodeĢ. Whichever interface is used, all roads lead to the same place – DBL Helper. You can view these files from the CM platform web portal or via the command shell:įor device configurations, the TFTP service creates configuration files based on the data entered into the CUCM admin web portal, via the AXL/SOAP interface, or through the Bulk Administration Tool.

Once you load the package, all binary files are stored on the TFTP server. A package usually contains multiple binary images that are used by the phone.

For binary images that the TFTP service provides you must load or install a package containing the appropriate firmware loads. In addition the TFTP service is responsible for generating configuration and security files. The role of the Cisco TFTP service is to serve files such as firmware images to requesting services or end points. I typically recommend having two TFTP services in the cluster and I prefer not to run this service on the Publisher or call processing nodes in larger environments. non call processing services) to the cluster and its endpoints. Depending on the size of your deployment, you may have this service running on the Publisher node or multiple nodes dedicated to providing supplementary services (i.e. The Cisco Unified Communications (CUCM) solution architecture has a TFTP service that you enable on one or more servers in a given cluster.
