Several packet handling applications are focused on one technique such as balancing or filtering. Other applications can require various mixtures and variations of techniques to achieve more multi-faceted use-cases.
The Packet Wrangler, pne-pwr, is a flexible platform that performs a selection of wrangling techniques on Ethernet packets at Layers 2 – 4 on links at speeds from 10G to 400G. The primary platform operates at line rate for non-context techniques such as tuple-hashing load-balancing. The pne-pwr platform can be extended with contextual processors to perform such techniques such as Sticky load-balancing. The capacity of the primary platform units are 32 x 100G and 32 x 400G links. On both platforms the links can be broken down into smaller capacity links – 100, 50, 40, 25, 10G links.
