METHOD AND SYSTEM FOR FACILITATING LOSSY DROPPING AND ECN MARKING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18626452 titled 'METHOD AND SYSTEM FOR FACILITATING LOSSY DROPPING AND ECN MARKING

Simplified Explanation

The patent application describes methods and systems for performing lossy dropping and ECN marking in a flow-based network. The system can maintain state information of individual packet flows dynamically, allowing for per-flow packet dropping and ECN marking.

• Each flow in the network is provided with a flow-specific input queue at a switch.
• Packets of a flow are acknowledged at the egress point and acknowledgement packets are sent back to the ingress point.
• Switches can obtain state information of each flow to perform per-flow packet dropping and ECN marking.

Key Features and Innovation

• Dynamic maintenance of state information for individual packet flows.
• Per-flow packet dropping and ECN marking.
• Acknowledgement packets sent back to the ingress point for each flow.

Potential Applications

This technology can be applied in:

• Network traffic management systems.
• Quality of Service (QoS) implementations.
• Network congestion control mechanisms.

Problems Solved

• Efficient packet dropping and ECN marking in flow-based networks.
• Dynamic setup and release of state information for individual flows.
• Improved network performance and congestion control.

Benefits

• Enhanced network efficiency.
• Improved Quality of Service for network traffic.
• Better congestion management in flow-based networks.

Commercial Applications

• "Dynamic Flow State Management System for Network Traffic Optimization"
• This technology can be utilized in telecommunications companies for optimizing network traffic flow.
• It can also be integrated into data centers to improve network performance and reliability.

Questions about Flow-Based Network Management

How does the system maintain state information for individual packet flows?

The system maintains state information by dynamically setting up or releasing flow-specific input queues at switches for each flow.

What are the potential applications of per-flow packet dropping and ECN marking?

Per-flow packet dropping and ECN marking can be applied in network traffic management systems, Quality of Service implementations, and network congestion control mechanisms.

Original Abstract Submitted

Methods and systems are provided for performing lossy dropping and ECN marking in a flow-based network. The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch. Packets of a respective flow are acknowledged after reaching the egress point of the network, and the acknowledgement packets are sent back to the ingress point of the flow along the same data path. As a result, each switch can obtain state information of each flow and perform per-flow packet dropping and ECN marking.
