Metron: NFV Service Chains at the True Speed of the Underlying Hardware
summary
Metron is an NFV platform that splits service chains into stateless hardware offloads (OpenFlow switches, Mellanox/DPDK NICs) and stateful software (fastClick) then maps traffic via tag-based hardware dispatching to specific cores, avoiding cache/DRAM handoffs and enabling zero intercore communication. On a 100 GbE testbed Metron hits the measured hardware limit (~76 Gbps with real small-packet traces), yields 4.7× lower latency and up to 7.8× throughput gains versus prior systems and up to 6.5x efficiency improvement over OpenBox.
