BNG CUPS separates the BNG architecture into the user plane (UP) and control plane (CP). This allows the CPs to be centralized and UPs to be distributed as requirements demand. It also allows the CP and the UP functions to scale and be innovated independently. Some of the key motivations and benefits of BNG CUPS are:

• Distributed BNG user planes to support edge computing requirements
• Distributed BNG user planes can support low latency and high throughput requirements
• Separate BNG control and user planes can optimize network costs
• Increased resilience with 1:N redundancy on UPs for greater resiliency at lower cost
• More cost-effective allocation of BNG subscriber licenses by enabling license pooling
• CPs can scale efficiently with a Kubernetes-based, cloud-native architecture
• Reduces OSS interfaces to BNG control planes, lowering maintenance and integration costs
• Time to market for new services is improved with BNG CUPS
• BNG CUPS can be a platform for innovative use cases to improve service and resiliency

ACG Research has developed a total cost of ownership (TCO) model to compare a traditional BNG architecture with an BNG CUPS implementation as prescribed by the BBF. Peter Fetterolf's whitepaper compares the TCO of traditional BNG deployments with an BNG CUPS architecture to quantify the economic advantages/disadvantages of each approach.
