Cflowd Filter Matching

In the filter-matching process, normally, every packet is matched against filter (access list) criteria

to determine acceptability. With cflowd, only the first packet of a flow is checked. If the first

packet is forwarded, an entry is added to the cflowd cache. Subsequent packets in the same flow

are then forwarded without needing to be matched against the complete set of filters. Specific

performance varies depending on the number and complexity of the filters.
