White boxes as uCPEs are general purpose and low-cost. However, they lack some carrier-grade, specialized functions and interface options that cannot be virtualized; in addition, more expensive white box models are required for compute-intensive functionalities. Pluggable physical network functions (P-PNFs) with the required physical interfaces, programmable hardware capabilities, and specialized components can help close these gaps for SDN and NFV-based services.

This white paper explores how P-PNFs can:
Upgrade any white box, switch and router with much needed missing, functionalities
Used on an “as needed” basis
Provide service consistency?across multiple vendor white box platforms
Eliminate the cost and operational complexity of standalone appliance deployments (e.g.,?space, power and cabling)?
