Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing FlexE technology does not support flexible establishment of a service path according to a service type and resource reservation scheme in a client private line scenario.
Innovation Solution
A method and device for establishing a service path by receiving request information including a service type and resource reservation scheme, computing a path based on FlexE link topology, and reserving resources accordingly on a FlexE link channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If FlexE technology is used for client private line scenario, then service isolation and bandwidth flexibility are achieved, but flexible establishment of service path according to service type and resource reservation scheme is not supported
Solution Approach 1:
The patent segments the service path establishment process into distinct phases: service type identification, resource reservation scheme determination, path computation, and resource reservation. This segmentation allows each phase to be handled independently, enabling flexible service path establishment while maintaining manageable protocol complexity through structured processing steps
Solution Approach 2:
The patent introduces dynamic adaptability by enabling the system to adjust service path establishment based on different service types (e.g., 5G, 10G, fine-grained services) and resource reservation schemes. The protocol dynamically selects appropriate establishment methods according to service requirements, achieving versatility without requiring a completely new protocol framework
2Adaptability or versatility
If GMPLS protocol is used for FlexE channel path establishment, then path establishment is supported, but flexible establishment according to service type and resource reservation scheme is not supported
Solution Approach 1:
The patent applies local quality by tailoring the service path establishment process to specific service types and resource reservation schemes. Different service types (coarse-grained vs. fine-grained) receive customized establishment procedures, allowing the system to optimize for each service's specific requirements while using the same underlying FlexE infrastructure
Solution Approach 2:
The patent performs preliminary actions by pre-defining service types and resource reservation schemes before actual path establishment. This preprocessing allows the system to have clear guidelines ready for path computation, simplifying the operation during execution while maintaining high adaptability to different service requirements

AI summary
Provided are a method and device for establishing a service path, an electronic apparatus, and a readable storage medium. The method includes: receiving request information for establishing a path for a service, where the request information includes a service type and a resource reservation scheme; computing a path for the service according to topology information of a FlexE link through which the service is transmitted and the request information; and reserving a resource and establishing a path for the service according to the service type and the resource reservation scheme, and a service type and a resource reservation scheme on a channel of the FlexE link through which the service is transmitted.
