Packet Forwarding Method, Apparatus, and System - A simplified explanation of the abstract
This abstract first appeared for US patent application 18157580 titled 'Packet Forwarding Method, Apparatus, and System
Simplified Explanation
The abstract describes a method for packet forwarding in a network. Here are the key points:
- A session management network element sends a path identifier to a first device.
- The first device consists of an access network element and a user plane network element for a specific protocol data unit (PDU) session.
- The path identifier indicates the first path from the access network element to the user plane network element.
- The first path may include a part or all of a second path, which is a pre-established path for another PDU session.
- The session management network element also sends identification information of a destination address corresponding to the path identifier to the first device.
Potential applications of this technology:
- This method can be applied in various network environments, such as telecommunications networks, to efficiently forward packets between network elements.
- It can be used in scenarios where multiple PDU sessions are active simultaneously, allowing for optimized routing and resource allocation.
Problems solved by this technology:
- The method simplifies the packet forwarding process by providing a path identifier and destination address information, reducing the complexity of routing decisions.
- It allows for efficient utilization of network resources by reusing pre-established paths for different PDU sessions.
Benefits of this technology:
- Improved network performance and reduced latency by optimizing packet forwarding.
- Simplified network management and configuration by using path identifiers instead of complex routing tables.
- Enhanced scalability and flexibility in handling multiple PDU sessions concurrently.
Original Abstract Submitted
A packet forwarding method includes that a session management network element sends a path identifier to a first device, where the first device includes an access network element corresponding to a protocol data unit (PDU) session and a user plane network element corresponding to the PDU session, the PDU session corresponds to a first terminal, the path identifier indicates a first path from the access network element to the user plane network element, the first path includes a part or all of a second path, and the second path is a path corresponding to a PDU session pre-established by the session management network element for a second terminal. The session management network element further sends, to the first device, identification information of a destination address corresponding to the path identifier.
