Examples of reasons to adjust image distribution priorities

You can use the Image Access Manager to modify the relative priorities applied for source stations to send images to destination stations.

In this scenario, the sources are two archives, AS1 and AS2, that both contain the same images. The destinations are two identical display stations, DS1 and DS2.

Default distribution

Each source and destination are weighted equally and are therefore equally used to distribute images to the destination stations.

Adjusting the distribution to take advantage of a faster source

If AS1 is a faster machine than AS2, you may want to set the priorities to send images using the faster archive more often. In this example, AS1 is called upon more often to distribute images to both DS1 and DS2, even though both archive stations contain the same images.

Adjusting the distribution to create an even load balance

To create a more even load balance for image distribution, set the priorities so that AS1 distributes images to DS1, and AS2 distributes images to DS2. That way, both display stations receive an equivalent number of images.

Note: A lower priority source for images is still available should the higher priority source become unavailable.
