Control Embedded Data Packet for Efficient ARP Query in SDA
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Software-Defined Access (SDA) solutions for Address Resolution Protocol (ARP) queries are inefficient due to excessive 'chattiness' among network elements, leading to delays in communication between end points, as they require multiple control plane message exchanges to determine remote location IDs for IP/MAC addresses.
Innovation Solution
Embedding data plane requests, such as ARP requests, within control plane packets for processing by control plane nodes equipped with both control plane and data plane functionality, reducing the need for multiple exchanges by enabling a single transaction that handles both control and data plane requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple control plane message exchanges are used to determine remote location IDs for IP/MAC addresses, then control plane functionality is maintained, but communication delays increase and network element chattiness increases
Solution Approach 1:
The patent merges control plane and data plane functionalities by embedding data plane packets within control plane packets. This allows a single control plane node to handle both control plane message exchanges and data plane packet forwarding, eliminating the need for separate message exchanges and reducing communication delays while maintaining control plane reliability
Solution Approach 2:
The control plane node is designed with multi-functionality, capable of processing both control plane requests and embedded data plane packets. This universal approach allows the same node to perform address resolution and packet forwarding functions, reducing the number of interactions needed and improving overall efficiency
2Measurement precision
If multiple control plane message exchanges are used to determine remote location IDs, then address resolution is thorough, but network element chattiness increases
Solution Approach 1:
By combining control plane and data plane processing in a single node, the patent reduces the number of messages exchanged between network elements. The control plane node can perform address resolution and packet forwarding in one operation, maintaining resolution accuracy while reducing chattiness
Solution Approach 2:
The control plane node acts as an intermediary that handles both control plane coordination and data plane packet forwarding. This mediator role allows it to resolve addresses and forward packets without requiring multiple separate message exchanges between different network elements
3Productivity
If data plane packets are embedded within control plane packets, then network element chattiness is reduced, but packet processing complexity increases
Solution Approach 1:
The patent combines control plane and data plane packet processing into a single unified operation at the control plane node. By embedding data plane packets within control plane packets and processing them together, the system reduces the number of separate processing steps and improves productivity despite the increased complexity of individual packet handling
