Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data switching systems face limitations in scalability due to the capacity constraints of core layer switching apparatuses, making it difficult to meet the growing demands of bandwidth and service expansion in cloud computing environments.
Innovation Solution
A data switching system is designed with multiple subsystems interconnected by intra-group and inter-group optical interleavers, allowing network side ports to function as both intra-group and inter-group ports, enabling a full mesh of switching apparatuses with only one type of switching apparatus, thereby overcoming capacity limitations and reducing the number of required fibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional core layer switching apparatuses are used to implement intercommunication between all servers, then network connectivity is achieved, but the system capacity is limited by the core switching apparatus capacity
Solution Approach 1:
The patent divides the network into multiple subsystems, each with its own switching apparatuses. This segmentation allows the system capacity to exceed the capacity of any single core switching apparatus by distributing traffic across multiple subsystems and interconnected switching nodes, thereby resolving the bottleneck of conventional single-core architectures.
Solution Approach 2:
The patent introduces a new architectural dimension by enabling switching apparatuses to function in multiple roles (intra-group ports for local subsystem communication, inter-group ports for subsystem interconnection). This multi-functional capability adds a dimensional layer to the network architecture, allowing capacity scaling without proportionally increasing complexity.
2Productivity
If multiple types of switching apparatuses are deployed to achieve full mesh connectivity, then network capacity is improved, but the number of required fibers and construction costs increase
Solution Approach 1:
The patent designs a universal switching apparatus that can perform multiple functions: serving as a core switching apparatus for inter-subsystem communication and as an access switching apparatus for intra-subsystem communication. This multi-functionality eliminates the need for separate switching apparatus types, reducing the total number of fibers required while maintaining full mesh connectivity and high network capacity.
Solution Approach 2:
The patent merges the functions of core switching and access switching into a single unified switching apparatus. By combining these previously separate roles into one device that can operate in different modes (intra-group and inter-group ports), the system achieves the same connectivity and capacity benefits with fewer fibers and lower construction costs.
3Adaptability or versatility
If core layer switching apparatus capacity is increased to meet future service development requirements, then network capacity is improved, but the system becomes more expensive and complex
Solution Approach 1:
The patent implements a dynamic network architecture where switching apparatuses can flexibly switch between different operational modes (intra-group or inter-group) based on traffic requirements. This dynamic adaptability allows the system to accommodate future service development needs by reconfiguring existing apparatuses rather than requiring proportional increases in capacity or complexity.
Solution Approach 2:
The universal switching apparatus designed in the patent can adapt to different network scenarios and future service requirements by performing multiple functions. This multi-functionality provides inherent adaptability for service expansion without requiring specialized high-capacity core apparatuses, thereby avoiding increased complexity and cost while maintaining the ability to meet future demands.

AI summary
The present invention provides a data switching system, including K subsystems, where a first subsystem in the K subsystems includes M switching apparatuses, a first switching apparatus in the M switching apparatuses includes X network side ports, and the X network side ports include M-1 intra-group ports and K-1 inter-group ports, where the M-1 intra-group ports are respectively connected to M-1 switching apparatuses in the first subsystem except the first switching apparatus; and the K-1 inter-group ports are respectively connected to direct switching apparatuses, of the first switching apparatus, in K-1 subsystems in the K subsystems except the first subsystem. Such a structure improves a capacity of a switching system in a case in which no core switching apparatus is required.
