Network Device Forwarding Path Determination for Service Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network slice service data cannot be forwarded in a bearer network, leading to inefficiencies in traffic management and resource utilization.
Innovation Solution
A method and network device that determine a forwarding path for service data based on network resource configuration information and network slice associations, ensuring that service data is routed through matching network slices, utilizing techniques like Segment Routing and Interior Gateway Protocol extensions to identify and manage network slices within the bearer network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing technology is used to segment virtual networks on the same infrastructure, then traffic isolation and service customization are improved, but the capability to forward network slice service data in the bearer network is lost
Solution Approach 1:
The patent applies segmentation by dividing the bearer network into multiple network slices, where each slice is assigned to specific service data. The network device segments the forwarding process by determining a forwarding path based on the network slice identifier, ensuring that different service data are forwarded through appropriate network slices while maintaining traffic isolation and enabling reliable forwarding capability.
2Reliability
If traditional forwarding methods are used in the bearer network, then forwarding capability is maintained, but network slice service data cannot be forwarded
Solution Approach 1:
The patent applies dynamics by making the forwarding path determination adaptive rather than static. The network device dynamically determines the forwarding path based on the network slice identifier of the service data, allowing the forwarding behavior to change according to the specific service requirements while maintaining reliable forwarding capability for all service data types.
3Speed
If service data is forwarded without matching network slice resources, then forwarding speed is improved, but traffic management efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-establishing the association between network resources and network slices through network resource configuration information. The network device uses this pre-configured information to quickly determine the appropriate forwarding path based on the network slice identifier, enabling fast forwarding while maintaining efficient traffic management through pre-planned resource allocation.

AI summary
Provided is a method for forwarding service data, a network device, and a network system. The forwarding method may include the following operation. A forwarding path for service data is determined according to network resource configuration information of a designated network and a network slice of the service data, wherein the network resource configuration information indicates one or more network slices associated with one or more network resources of the designated network, and a network slice associated with a network resource of the determined forwarding path matches the network slice of the service data; and the service data is forwarded according to the forwarding path.
