Detailed Description

memory manager used by the forwarding table

This manager allocates and keeps track of blocks of memory. Individual segments of these blocks are then made available to users. The manager does not keep track of each individual segment. Rather it allows the user to deallocate all the memory at once. This memory manager is ideal for "dictionary" type data structures that allow only growing structure.
