Elastic Flow Distributor (EFD) is a distributor library that uses
perfect hashing to determine a target/value for a given incoming flow key.
It has the following advantages:
- First, because it uses perfect hashing, it does not store
the key itself and hence lookup performance is not dependent
on the key size.
- Second, the target/value can be any arbitrary value hence
the system designer and/or operator can better optimize service rates
and inter-cluster network traffic locating.
- Third, since the storage requirement is much smaller than a hash-based
flow table (i.e. better fit for CPU cache), EFD can scale to
millions of flow keys.
Finally, with current optimized library implementation performance
is fully scalable with number of CPU cores.
