Aggregation Port ID Allocation in Distributed Link Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IEEE802.1AX-based link aggregation technologies are limited in supporting port aggregation across multiple systems, leading to a lack of effective solutions for ensuring the uniqueness and unified allocation of aggregation port IDs in distributed link aggregation systems, which affects network reliability and redundancy.
Innovation Solution
A method and device for allocating aggregation port IDs, where a portal master system allocates IDs to both itself and slave systems within a link aggregation group, with negotiation or pre-configuration to determine master and slave systems, and includes validation and re-allocation processes to ensure ID uniqueness and resource efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional IEEE802.1AX-based link aggregation is used, then port aggregation on one system is supported, but port aggregation across multiple systems cannot be supported
Solution Approach 1:
The system is segmented into a portal master system and portal slave systems. The portal master system is responsible for unified aggregation port ID allocation across all systems, while portal slave systems execute the allocation and manage their respective aggregation ports. This segmentation enables multi-system aggregation support while distributing complexity across multiple components.
2Reliability
If unified allocation method is implemented across multiple portal systems, then aggregation port ID uniqueness is ensured, but system complexity increases
Solution Approach 1:
The portal master system acts as an intermediary between multiple portal slave systems for aggregation port ID allocation. The master system receives allocation requests from slave systems, performs unified allocation to ensure uniqueness, and distributes the allocated IDs back to the slave systems. This intermediary approach ensures ID uniqueness while centralizing allocation management logic.
3Reliability
If each physical port has a unique ID in LACP system, then ID uniqueness is maintained, but coordination across multiple systems becomes complex
Solution Approach 1:
Each portal slave system autonomously sends allocation requests to the portal master system and receives aggregated port ID assignments. The slave systems self-configure their aggregation ports using the allocated IDs without requiring manual coordination. This self-service mechanism maintains ID uniqueness while simplifying operational coordination across multiple systems.

AI summary
The present invention provides a method and device for allocating aggregation port Identifiers (ID). The method includes that: a portal master system at one end of an link aggregation group allocates an aggregation port ID to an aggregation port of the portal master system, and allocates an aggregation port ID to a corresponding aggregation port of a portal slave system according to an aggregation port ID allocation request of the portal slave system at the end of the link aggregation group. By the present invention, problems of aggregation port ID allocation of multiple portal systems in one end of the link aggregation group in a related art are solved, and a beneficial effect of realizing unified aggregation port ID allocation to ensure the uniqueness of the aggregation port IDs is achieved.
