Elements to Configure DMS-CD Deployment Thresholds (continued)

 

Enable maximum Enforces or ignores a maximum transfer rate that you specify.

transfer rate

This rate is the upper threshold allowed for bandwidth consumption by DMS-CD during its deployments

 

 

to any one DMP in your WAN. We measure this rate in kilobits per second (Kbps). The value that you

 

enter should be less than the maximum transfer rate of your network.

 

In combination with the Number of concurrent deployments value and the number of DMPs in a group

 

that you target, this threshold limits how much bandwidth DMS-CD can consume during a deployment.

 

For example, assume for a moment that QoS policies in your network limit DMS-CD bandwidth

 

utilization to a maximum of 64 Kbps, and you have enabled the maximum transfer rate setting with a

 

value of:

64 Kbps — Individual DMPs will each consume 64 Kbps per deployment. So, if you then set the number of concurrent deployments value to 10, you will use 64 Kbps x 10 = 640 Kbps. Furthermore, you cannot set the Number of concurrent deployments value any higher than 1, because 64 x 1 = 64.

32 Kbps — Individual DMPs will each consume 32 Kbps per deployment. So, if you then set the number of concurrent deployments value to 10, you will use 32 Kbps x 10 = 320 Kbps. Furthermore, you cannot set the Number of concurrent deployments value any higher than 2, because 32 x 2 = 64.

21 Kbps — Individual DMPs will each consume 21 Kbps per deployment. So, if you then set the number of concurrent deployments value to 10, you will use 21 Kbps x 10 = 210 Kbps. Furthermore, you cannot set the Number of concurrent deployments value any higher than 3, because 21 x 3 = 64.

 

The permitted value is any whole number in the range from 28 to 102400, where 102400 Kbps is the same

 

as 100 Mbps. The factory-default setting ignores this threshold. If you prefer to enforce it, check the

 

check box.

 

 

Deployment

FTP or SFTP, according to your security requirements.

Protocol

When you choose SFTP, connections are encrypted between your DMM server and your DMPs.

 

 

Otherwise, these sessions use clear text. Even though the factory-default setting is FTP, we recommend

 

that you use SFTP.

 

 

Maximum file

The maximum number of megabytes — per file — that DMS-CD will transport inside a multifile

size (in MB)

deployment package to your DMPs, before the file that reached this threshold is moved to the back of the

 

queue and its transfer is deferred.

 

The next file advances to the front of the queue and the deployment continues. DMS-CD applies this

 

threshold to a deployment package as many times as necessary until it has cycled through all of its files,

 

and then the transfer is resumed for the deferred file after it returns to the front of the queue. This

 

threshold might cause the transfer of any especially large file to be distributed across days. Bottlenecks

 

are prevented and as many assets are provisioned as can be provisioned.

 

The permitted value is any whole number in the range from 10 to 1024000, where 1,024,000 MB is the

 

same as 1 TB. The factory-default maximum size is 600 MB.

 

Note Although it is technically feasible to enter a file size as great as 1024000 MB, playback fails for

 

any file that is larger than 1.9 GB, regardless of the DMP model type. This size is constrained by

 

the limits of streaming.
