Abstract
A method of remapping allocated memory in a queue based switching element having first and second memory elements each allocated to a first port pair. An unallocated block of memory is identified in the first memory element as a candidate block, and an allocated block of memory is identified in the second memory element as a target block. Block information is copied from the target block to the candidate block, and the candidate block is maintained as unallocated. In response to a determination that read and write pointers are in a suitable position for a remapping operation, the candidate block is allocated and the target block is deallocated so that the second memory element becomes unallocated and available for reallocation to a second port pair.
