Abstract
A software-implemented switching path includes separate control and data planes with the data plane having a graph of feature nodes with each node implementing a feature to be applied to a packet being switched. Each feature node includes private data and code which are utilized to apply the feature to the packet. The packet is switched to a next node based on packet-specific context data.
