MULTICAST PACKET PROCESSING METHOD AND DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18461597 titled 'MULTICAST PACKET PROCESSING METHOD AND DEVICE
Simplified Explanation
The patent application describes a method and device for multicast packet processing. The method involves generating multiple multicast packets with different identifiers to identify different forwarding paths for each packet. This allows for the identification of multiple multicast data flows and enables various functions such as packet loss and delay detection, path restoration, and more.
- The method involves obtaining a data packet and generating multiple multicast packets based on it.
- The first multicast packet includes first iFIT information and a first multi-level flow identifier.
- The second multicast packet includes the first iFIT information and a second multi-level flow identifier.
- The different multi-level flow identifiers are used to identify different forwarding paths for the multicast packets.
- This method enables the identification and processing of multiple multicast data flows in a point-to-multipoint multicast data flow transmission scenario.
- It allows for iFIT detection on each data flow, enabling functions like packet loss and delay detection, path restoration, and more.
Potential Applications
This technology can be applied in various scenarios where multicast packet processing is required, such as:
- Video streaming: It can be used to ensure smooth and uninterrupted streaming of multicast video content.
- Teleconferencing: It can help in improving the quality and reliability of multicast audio and video streams during teleconferencing sessions.
- Content delivery networks: It can be utilized to efficiently distribute content to multiple users simultaneously.
Problems Solved
The technology addresses several problems related to multicast packet processing, including:
- Packet loss and delay: By performing iFIT detection on each multicast data flow, the method enables the detection and mitigation of packet loss and delay issues.
- Path restoration: The different multi-level flow identifiers allow for the identification of different forwarding paths, enabling path restoration in case of failures or congestion.

- Enhanced reliability: The ability to identify and restore different forwarding paths improves the reliability of multicast transmissions, reducing the risk of disruptions.
- Efficient resource utilization: By efficiently managing multiple multicast data flows, the method optimizes the utilization of network resources, leading to improved performance and scalability.
Original Abstract Submitted
A method and device for multicast packet processing are disclosed. The method includes: A first network device obtains a data packet; and the first network device generates a first multicast packet and a second multicast packet based on the data packet. The first multicast packet includes first iFIT information and a first multi-level flow identifier. The second multicast packet includes the first iFIT information and a second multi-level flow identifier. The first multi-level flow identifier and the second multi-level flow identifier are different, to identify different forwarding paths of the generated first multicast packet and second multicast packet respectively. In the method, in a point-to-multipoint multicast data flow transmission scenario, a plurality of multicast data flows can be identified, to perform iFIT detection on each of the plurality of data flows, so as to implement packet loss and delay detection, path restoration, and the like for the multicast data flows.
