Abstract
A method for decrementing a reference count in a multicast environment is provided that includes receiving an access request for a particle stored in a memory element. The memory unit is then accessed in response to the access request, the particle being read from the memory element. The particle includes a plurality of data segments, a selected one or more of which includes a first reference count associated with the particle. The particle is then presented to a target that generated the access request. The first reference count associated with the selected one or more data segments is then decremented in order to generate a second reference count. At least one of the plurality of data segments with the second reference count is then written to the memory element.
