Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switch stacking technologies in enterprise campus networks face challenges such as traffic flooding during learning stages, require specialized protocols, and have single points of failure, making it difficult to manage growth and maintain the network efficiently.
Innovation Solution
Forming a switch ring where all switches participate equally in Layer 3 routing without specialized stacking protocols, allowing for independent management by a cloud server, automatic failure detection, and seamless addition or removal of switches without service disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If switch stacking technology is used to connect multiple switches, then network coverage and functionality are increased, but traffic flooding occurs during learning stages and specialized stacking protocols are required
Solution Approach 1:
The patent changes the operational layer parameter from Layer 2 to Layer 3 routing, eliminating the learning stage flooding issue inherent in Layer 2 switching by using IP-based routing decisions instead of MAC address learning
Solution Approach 2:
The patent extracts and eliminates the specialized stacking protocols by using standard Layer 3 routing protocols, removing the harmful dependency on proprietary communication methods between switches
2Ease of operation
If switch stacking with master and standby roles is implemented, then switch management is structured, but single points of failure are created reducing network reliability
Solution Approach 1:
The patent creates equipotentiality by making all switches equal peers in the network without master or standby designations, ensuring that any switch can perform routing functions and there is no single point of failure for management or operation
Solution Approach 2:
The patent segments the network into independent routing entities where each switch operates autonomously with equal capabilities, breaking the hierarchical dependency structure that creates single points of failure
3Quantity of substance
If multiple switches are connected using traditional stacking, then port capacity is increased, but device complexity and specialized protocols are required
Solution Approach 1:
The patent applies universality by using standard Layer 3 routing protocols that can operate across any network device, eliminating the need for specialized stacking protocols and making the system universally compatible without adding complexity
4Adaptability or versatility
If switches are added or removed from the network, then network scalability is improved, but service disruption occurs in traditional stacking configurations
Solution Approach 1:
The patent applies dynamics by implementing dynamic routing protocols that automatically adapt to network topology changes, allowing switches to be added or removed without service disruption as routing paths are dynamically recalculated
