Storage Area Network Congestion Notification Endpoint Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current storage area network (SAN) technologies lack the ability for network devices to communicate congestion events to servers or endpoint devices, leading to delayed detection and response to network congestion, which affects quality of service and can result in queueing delays, packet loss, and blocked connections.
Innovation Solution
Implementing a system where network devices in the SAN register endpoint devices to receive congestion notifications, allowing them to detect and transmit data about congestion events to registered endpoint devices, enabling timely adjustments and improving network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network devices in SAN do not implement congestion notification capability, then the system structure remains simple, but the quality of service deteriorates due to delayed detection and response to congestion events
Solution Approach 1:
The patent implements preliminary action by having network devices proactively detect congestion events and send notifications to endpoint devices before severe performance degradation occurs. The system pre-establishes notification mechanisms and registration processes so that when congestion is detected, immediate action can be taken by endpoint devices to mitigate quality of service issues.
Solution Approach 2:
The patent implements feedback by creating a closed-loop communication system where network devices monitor congestion conditions, send notifications to registered endpoint devices, and enable those devices to respond accordingly. This feedback mechanism allows the system to adapt to changing network conditions and maintain quality of service through informed decision-making at the endpoint level.
2Loss of time
If network devices implement congestion notification to endpoint devices, then response time to congestion events is reduced, but the device complexity increases due to additional registration and notification mechanisms
Solution Approach 1:
The patent implements self-service by allowing endpoint devices to autonomously register with network devices for congestion notifications and to independently respond to received notifications according to their own policies. This self-service approach reduces the need for complex centralized control mechanisms, as each device manages its own notification preferences and response actions, thereby reducing overall system complexity while maintaining fast response times.
3Reliability
If endpoint devices are registered to receive congestion notifications, then packet loss is reduced through timely responses, but the quantity of communication overhead increases
Solution Approach 1:
The patent implements local quality by allowing different endpoint devices to have customized notification registration profiles and response policies tailored to their specific requirements. Rather than implementing a uniform notification system across all devices, the system enables selective registration and differentiated response behaviors, reducing unnecessary communication overhead for devices that do not require or can handle congestion notifications differently.

AI summary
Embodiments of the invention are directed to registering one or more endpoint devices to receive a notification and detecting a congestion event related to a storage area network. The storage area network includes the one or more endpoint devices. The notification is sent regarding the congestion event to the one or more endpoint devices that have been registered for the notification.
