Typedef Documentation

bier_fmask_db_t

typedef struct bier_fmask_db_t_ bier_fmask_db_t

Global Table of fmask objects The key into this table includes the table's key and the fmask's key, so there could be a DB per-table.

But it is more efficient at forwarding time to extract the fmask from a single global table which is hot in dcache.

The table's key is part of this DB key, since the fmasks therein build up their forwarding mask based on the routes that resolve through it, so cross polination would be bad.
