Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing broadband network gateway (BNG) systems face performance issues due to excessive communication between physical optical line terminal (pOLT) and disaggregated BNG user plane (DBNG-UP) devices, leading to increased resource utilization and reduced efficiency in processing network configuration information packets.
Innovation Solution
Implementing a pOLT+DBNG-UP device that determines and includes circuit and remote identifiers within packet headers, eliminating the need for multiple communications with a dOLT device, thereby reducing resource usage and packet modification, and enhancing performance by optimizing packet flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple communications with dOLT device are implemented, then packet processing can be performed, but computing and communication resource usage increases
Solution Approach 1:
The pOLT+DBNG-UP device performs preliminary actions by determining circuit identifiers and remote identifiers locally before packet processing, and includes these identifiers in the packet header upfront. This eliminates the need for subsequent communications with the dOLT device, thereby reducing computing and communication resource usage while maintaining packet processing capability.
Solution Approach 2:
The packet header acts as an intermediary carrier that includes the circuit identifier and remote identifier determined by the pOLT+DBNG-UP device. This intermediary structure allows the DBNG-CP device to process packets directly without requiring additional communications with the dOLT device, thus optimizing resource usage.
2Reliability
If multiple communications with dOLT device are implemented, then network configuration can be obtained, but communication time increases
Solution Approach 1:
The pOLT+DBNG-UP device performs preliminary determination of circuit identifiers and remote identifiers locally before packet processing, and includes these identifiers in the packet header upfront. This eliminates the need for subsequent communications with the dOLT device, thereby reducing communication time while maintaining network configuration accuracy.
3Productivity
If packet modifications are performed, then routing can be optimized, but packet integrity may be compromised
Solution Approach 1:
The invention extracts the necessary identification information (circuit identifier and remote identifier) from the packet processing function and places it in the packet header as pre-determined data. This extraction eliminates the need for subsequent packet modifications while maintaining routing efficiency and packet integrity.

AI summary
A first device associated with a physical optical line terminal (pOLT) and a disaggregated broadband network gateway user plane (DBNG-UP) may receive, from a second device associated with an optical network unit (ONU), a first packet associated with a request for network configuration information. The first device may determine, based on the first packet, a circuit identifier associated with a communication link between the first device and the second device, and a remote identifier associated with the second device. The first device may send to a third device associated with a disaggregated broadband network gateway control plane (DBNG-CP), the first packet and additional information that includes the circuit identifier and the remote identifier. The first device may receive from the third device a second packet associated with a response to the request for the network configuration information, and may send the second packet to the second device.
