Static Designated Forwarder Election Procedure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dynamic designated forwarder election procedures in networks are computationally intensive and lack predictability, making it difficult to determine which provider edge network devices will be selected as designated or non-designated forwarders, especially in networks with increasing quantities of devices and Ethernet virtual private network instances.
Innovation Solution
Implementing a static designated forwarder election procedure that configures network devices to perform a static designated forwarder role based on shared configuration, reducing processing resources and enhancing user control over network operations by ensuring consistent selection of designated forwarders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If dynamic designated forwarder election procedure is used, then network devices can automatically select designated forwarders, but computational resources are consumed and predictability is reduced
Solution Approach 1:
The patent applies preliminary action by pre-configuring network devices with designated forwarder roles before network operations begin. Instead of performing dynamic elections during network operation, the designated forwarder status is established in advance through configuration, eliminating the need for continuous computational resource consumption while maintaining automation.
2Extent of automation
If dynamic designated forwarder election procedure is used, then network devices can automatically select designated forwarders, but predictability of selection is reduced
Solution Approach 1:
The patent implements preliminary action by establishing designated forwarder configurations in advance, ensuring that the selection outcome is predetermined and highly predictable. This eliminates the uncertainty inherent in dynamic election procedures while maintaining automated operation through pre-established configurations.
3Use of energy by moving object
If static designated forwarder configuration is used, then processing resources are reduced and predictability is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by enabling network devices to autonomously determine and maintain their designated forwarder status based on pre-configured parameters. Devices independently perform role determination without requiring complex centralized management, reducing processing resource consumption while avoiding significant increases in device complexity through automated self-configuration mechanisms.
