HARDWARE ACCELERATED PATH TRACING ANALYTICS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18227602 titled 'HARDWARE ACCELERATED PATH TRACING ANALYTICS
Simplified Explanation: The patent application describes techniques for processing path tracing probe packets using hardware without the involvement of a path tracing collector component of a network controller. Source nodes assign random flow labels to probe packets, which are then sent through the network to a sink node for analysis.
Key Features and Innovation:
- Source nodes generate random flow labels for probe packets.
- Sink nodes determine if a flow indicated by a probe packet has been traversed before.
- Sink nodes calculate latency values associated with flows and store probe packets in corresponding latency bins.
- Telemetry data representing probe packets stored in latency bins can be sent to a network controller for further analysis.
Potential Applications: This technology can be applied in network monitoring, performance optimization, and troubleshooting in large-scale networks.
Problems Solved:
- Efficient processing of probe packets in network monitoring.
- Real-time analysis of network latency and flow traversal.
Benefits:
- Improved network performance monitoring.
- Enhanced troubleshooting capabilities.
- Real-time analysis of network latency.
Commercial Applications: This technology can be used in data centers, cloud computing environments, and large enterprise networks for efficient network monitoring and optimization.
Prior Art: Prior art related to this technology may include research on network monitoring techniques and hardware-based packet processing in networks.
Frequently Updated Research: Researchers may be exploring advancements in hardware-based network monitoring techniques and real-time analysis of network traffic for performance optimization.
Questions about Path Tracing Probe Packets: 1. What are the potential commercial applications of this technology? 2. How does this innovation improve network monitoring and troubleshooting processes?
Original Abstract Submitted
Techniques for processing path tracing probe packets using hardware (e.g., hardware memory of a node) and without the involvement of a path tracing collector component of a network controller. A source node may be configured to generate and assign random flow labels to a large number of probe packets and send them through the network to a sink node. The sink node may determine whether a flow indicated by the probe packet has previously been traversed. Additionally, the sink node may determine latency values associated with the flows, and store probe packets in corresponding latency bins. The latency bins may be stored in hardware memory of the sink node. Telemetry data representing the probe packets stored in the latency bins may be sent to a network controller for further network analysis.
