Interior nodes of the STRG group Cells into resource
groups, providing a mechanism for assigning resources
to related Cells. For instance, resource groups provide an
obvious mechanism for distributing resources to multiple
Cells that are part of a single application or service domain
2
. As another example, Tessellation’s pre-allocation
mechanism allows resources to be reserved for future use
by a particular Cell while exported to other Cells in a resource group as temporary (revocable) excess resources.
