Examples of Distiller in a sentence
Contracts can be computed recursively for chains of NFs as well.To help operators and developers handle the PCVs in con- tracts, BOLT comes with a tool we call the Distiller, which takes as input a packet trace and computes the PCV values that result from that trace being processed by the target NF.We evaluate the accuracy and utility of BOLT-generated performance contracts for four NFs written in C using DPDK: a NAT, a Maglev [17]-like load balancer, an LPM router, and a MAC bridge.
To reason about this, BOLT provides an additional tool called the Distiller.The Distiller takes as input the NF code and a sample of real-world traffic (as PCAP files).
Longer prefixes lead to 32% worse performance (133 vs 101 instructions) but may (hypothetically) account for only 1% of traffic.An operator can leverage the Distiller to balance risk with resource utilisation to decide how to provision the network.
A performance contract describes the performance of NF software running on a particular hardware configuration.Contract CU : I → F is a map from input classes to∈∈N Utract construct (§2), then describe how BOLT generates per- formance contracts (§3) and how the BOLT Distiller helps obtain a concrete performance number from a performance contract given a particular packet trace (§4).
A performance contract that distills how implementation affects performance into a simple expression would arguably be welcome in such cases.If desired, operators and developers can bind the PCVs in the performance expressions to values chosen by themselves or by the BOLT Distiller.
