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.
