I would most likely recommend plain parent relations with no relations
from the parent to the child caches..

All remote caches use the central parent cache cluster, most likely in a
TCP only configuration not using ICP.

The central parent cache cluster should most likely not have any
relations to the remote caches.

The exeption being if you cannot size the central cache sufficiently
large. In such case selected sibling relations to the larger remote
caches may be of value, but it is highly doubtful the cache benefit will
outweigth the increased latency incurred by the sibling relation ICP
querying.. Quite likely the contents of your remote caches will grow
quite similar, making relations that connect (directly or indirectly)
two remote caches of very limited value.
