Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for establishing cross-layer service connections in multi-layer networks are complex and inefficient, requiring manual configuration of interface parameters, which is time-consuming and labor-intensive, especially when network resources are insufficient, leading to prolonged connection establishment times.
Innovation Solution
A method and system that automatically negotiate and configure interface parameters by adding an interface parameter object to a UNI request message, which carries configuration parameters for both local and remote devices, enabling automatic setup of service connections through RSVP-TE signaling, thereby reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual configuration of interface parameters is used, then configuration accuracy can be ensured, but configuration time and labor cost increase significantly
Solution Approach 1:
The system enables automatic negotiation and configuration of interface parameters between network devices. The local device autonomously obtains remote device parameters, constructs configuration objects, and completes the configuration process without manual intervention, making the system self-configuring while ensuring accuracy through structured parameter objects.
Solution Approach 2:
The interface parameters of the remote device are obtained in advance before the actual configuration process. By pre-fetching parameters such as device type, interface type, and protocol information, the system prepares all necessary configuration data beforehand, enabling rapid automated configuration without compromising accuracy.
2Productivity
If automatic negotiation of interface parameters is implemented, then configuration efficiency improves, but system complexity increases
Solution Approach 1:
The patent introduces an interface parameter object as an intermediary data structure that standardizes the exchange of configuration information between devices. This object serves as a mediator that encapsulates complex parameters in a structured format, simplifying the automatic negotiation process while maintaining configuration efficiency.
Solution Approach 2:
The system dynamically adjusts interface parameters based on automatic negotiation results. By changing parameters such as device type, interface type, and protocol configurations based on real-time network conditions and device capabilities, the system achieves high efficiency without requiring complex manual intervention logic.
3Manufacturing precision
If comprehensive interface parameters are collected, then configuration completeness improves, but information processing load increases
Solution Approach 1:
The interface parameters are segmented into distinct categories such as device type, interface type, and protocol information. Each parameter is organized in separate fields within the interface parameter object, allowing selective processing and transmission of only necessary parameters, reducing overall processing load while maintaining completeness.
Solution Approach 2:
The interface parameter object serves multiple functions simultaneously: it stores configuration data, validates parameter compatibility, guides the configuration process, and enables automated negotiation. This multi-functional design reduces the need for separate processing mechanisms for each parameter type, optimizing information processing efficiency.

AI summary
A method, a system, and a device for establishing a service connection are provided. The method includes the following steps. An interface configuration parameter is obtained, in which the interface configuration parameter includes an interface configuration parameter of a remote device. An interface parameter object is added to a user network interface (UNI) request message, in which the interface parameter object carries the interface configuration parameter. The UNI request message carrying the interface configuration parameter of the remote device is sent to the remote device, so as to establish a service connection with the remote device. Thus, the interface parameter object is added to the UNI request message, and then the UNI request message carrying the interface configuration parameter of the remote device is sent to the remote device, for establishing the service connection, so as to realize automatic negotiation and configuration of the interface parameters, thereby saving manpower resources.
