3 Pay-As-You-Grow Licensing
PAYG licensing is a new licensing method to support the purchase and activation of 
IP router assemblies and platforms that more accurately addresses the focused and 
evolving needs of Nokia customers. An initial system purchase can be targeted to the 
the immediate requirements of small or large systems. At some later time, as network 
requirements evolve, these systems can be upgraded through software license 
distribution to increase system capacity and features. PAYG licensing also supports 
the repurposing of cards from one role in the network to an another role.
PAYG licensing is introduced in three phases that address the key components of 
the routers.
• Phase 1 introduces licensing of FP4-based hardware assemblies. A single 
physical card design might now be sold as nine or more variants. These variants 
all use the same card type but have different license levels encoded into the 
hardware. Each level defines different limits to the hardware capacity and to the 
functionality for that variant. Both the correct card type and license level must be 
provisioned for a card to be brought out of reset.
• Phase 2 introduces the ability to change the license level of an FP4 hardware 
assembly via downloaded software licenses. Phase 2 unlocks higher limits for 
an assembly without requiring any replacement of hardware.
• Phase 3 introduces licensing of specialized system-level software features and 
their scale for both FP3 and FP4 based systems. These system-level features 
will be the set of features for which RTUs exist today. To use one or more of 
these features, a software license must be downloaded to the system. If the 
system detects a feature in use, it will permit the feature to be used but will raise 
an indication to inform the operator that the system is missing the required 
license.
Phase 1 and 2 were introduced in Release 16.0. Phase 3 is scheduled for 
introduction in Release 20. 
The key customer benefit is the ability to purchase hardware that is tailored to 
specific roles in the network. For example, customers can purchase core routing 
cards for the interconnection of their routers within their network and only purchase 
high capacity cards for the network edge where those capabilities are needed. A core 
routing card is scaled for a lower number of services as it will only be used on internal 
network links. In addition, the customer can initially purchase lower connector or 
bandwidth capacity variants of cards with the knowledge that as network 
requirements grow, they will be able to unlock extra capacity through a software-only 
upgrade process.
