Reciprocal Master-Slave IP Network Resource Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IP networks fail to meet the high quality of service (QoS) and reliability requirements for Next Generation Networks (NGN) due to insufficient network resource utilization and complex configuration in master-slave bi-planes networking.
Innovation Solution
The method involves configuring Plane A and Plane B with reciprocal master-slave relations, assigning IP addresses to access device interfaces, and distributing services across these planes to ensure load-sharing and efficient service recovery, with interfaces having explicit or priority-based reciprocal master-slave configurations to handle failures and maintain service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Plane A and Plane B are configured with master-slave relation for backup, then network reliability is improved, but network resource utilization deteriorates because only one plane carries service at a time
Solution Approach 1:
The patent implements dynamic master-slave role switching between Plane A and Plane B based on real-time service distribution needs. The access device can flexibly switch which plane serves as master and which as slave, allowing both planes to be utilized for service carrying rather than keeping one idle for backup purposes only.
Solution Approach 2:
The patent pre-configures both Plane A and Plane B with reciprocal master-slave relations before service distribution begins. This preliminary setup ensures that both planes are ready to carry services immediately, eliminating the need to keep one plane idle as a passive backup, thereby improving resource utilization while maintaining reliability.
2Loss of energy
If services are distributed to multiple IP addresses in turn, then network resource utilization is improved, but service distribution complexity increases
Solution Approach 1:
The access device automatically performs service distribution across multiple IP addresses based on pre-configured reciprocal master-slave relations. The system self-manages the complexity of distributing services to multiple planes without requiring external control or complex configuration, reducing operational complexity while improving resource utilization.
3Reliability
If reciprocal master-slave relation is configured between interfaces, then failure recovery capability is improved, but configuration complexity increases
Solution Approach 1:
The reciprocal master-slave relation between interfaces is pre-configured before service deployment. This preliminary configuration establishes the failure recovery mechanism in advance, so that when failures occur, the system can automatically switch roles without requiring complex real-time configuration or manual intervention, thus improving reliability while keeping configuration manageable.

AI summary
A method for configuring IP network resource and an IP network are disclosed. The method includes: configuring a Plane A and a Plane B to have a reciprocal master-slave relation and to carry services individually, wherein the Planes A and B are connected with each other in a carrying network; configuring two interfaces of an access device with a reciprocal master-slave relation and assigning IP addresses to the Planes A and B respectively, to connect the Plane A with the Plane B; and distributing services to the IP addresses of the two interfaces in turn in the case that the IP address of a peer access device of the access device is unknown. The presently described technology can be easily implemented and can improve the network quality of service effectively, which can solve one or more problems in the conventional master-slave bi-planes networking, such as insufficient usage of the network resource, complex network policy configuration, etc.
