Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switch systems based on fiber channel (FC) networks require manual configuration of attributes for port settings, which is inefficient and prone to misconfiguration, especially when network topology changes, necessitating repetitive manual adjustments.
Innovation Solution
An attribute propagation method and switch system that automatically propagates attribute registration and deregistration messages across switches using the Switch Fiber Interactive Link Service (SW_ILS) protocol, allowing attributes to be registered and deregistered without manual intervention, utilizing timers and message lists to ensure efficient and reliable configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual configuration of attributes is performed for each port of all switches, then attribute configuration can be precisely controlled, but configuration efficiency is low and misconfiguration is prone to occur
Solution Approach 1:
The system enables automatic attribute propagation where switches self-configure by receiving and processing attribute propagation messages from network elements. Each switch automatically registers attributes for its ports and propagates them to adjacent switches without manual intervention, eliminating the inefficiency of manual configuration while maintaining accuracy through standardized message-based communication protocols
Solution Approach 2:
The patent implements preliminary action by pre-defining attribute states (empty state, first state, second state) and establishing propagation rules before actual configuration occurs. When a network element joins the network, the attribute propagation mechanism is already in place to automatically distribute attributes through the switch fabric, preventing configuration delays and errors that would occur with manual setup
2Adaptability or versatility
If manual reconfiguration is performed when network topology changes, then network connectivity can be maintained, but repeated manual operations increase time consumption and error risk
Solution Approach 1:
The system implements dynamic adaptation through automatic attribute propagation that responds to network topology changes in real-time. When network elements are added, removed, or moved, the attribute propagation mechanism dynamically updates switch port attributes through message exchange, enabling the network to adapt to topology changes without manual reconfiguration while maintaining connectivity and proper attribute distribution
Solution Approach 2:
The patent employs feedback mechanisms where switches monitor their port states and attribute registration status, and automatically initiate attribute propagation messages when changes are detected. This closed-loop feedback system ensures that attribute configuration automatically tracks with actual network topology, eliminating the need for manual reconfiguration while maintaining network adaptability

AI summary
An attribute propagation method and a switch system based on a fiber channel network are disclosed. According to the present invention, after an attribute is registered on one of its ports, each switch can automatically use its port on the other side to propagate this attribute, and a next adjacent switch can register this attribute on its port on the same side, so that ports on one side of all switches can have this attribute registered automatically. Hereafter, after the attribute is registered its port on the other side, each switch can automatically use its port on said one side that has been registered to propagate this attribute reversely and a next adjacent can register this attribute on its port on the other side, so that ports on the other side of all switches can automatically have this attribute registered. In this way, there is no need to manually configure each port. Instead, the attribute can be registered automatically on ports on both sides of all switches, thus improving the configuration efficiency for port attributes. Furthermore, the present invention can enable propagation of any attribute, thus making the present invention have a high popularity.
