Daisy Chain Aggregation Protocol Session Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aggregation protocols in network devices are limited to direct connections, preventing the use of a daisy chain arrangement that would allow multiple secondary devices to be connected to a single primary device, thereby restricting scalability and requiring separate connections for each secondary device.
Innovation Solution
Implementing a method where a primary network device establishes multiple aggregation protocol sessions with secondary devices using unique session identifiers, allowing non-directly connected devices to participate in aggregation protocol sessions and creating a logical link through a daisy chain topology, enabling the primary device to configure and control secondary devices as if they were directly connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If aggregation protocols are used only between directly-connected devices, then protocol implementation is simple and reliable, but scalability is limited and device cost increases
Solution Approach 1:
The patent introduces an intermediary mechanism where the primary device acts as a mediator to establish indirect aggregation protocol sessions. The primary device receives aggregation protocol packets from secondary devices and forwards them to the intended target, enabling non-directly-connected devices to participate in aggregation sessions without requiring direct protocol implementation between all pairs of devices.
Solution Approach 2:
The patent segments the aggregation protocol session establishment process into direct and indirect components. Direct sessions maintain simple reliable operation between connected devices, while indirect sessions are handled through the primary device's intermediary function, allowing scalability without compromising the reliability of direct connections.
2Reliability
If each secondary device is connected to the primary device by a separate port, then aggregation protocol sessions are reliable and simple to manage, but the number of required ports increases and cost increases
Solution Approach 1:
The patent makes the single physical link between the primary device and secondary devices serve multiple functions: it carries both data traffic and aggregation protocol packets, and enables both direct and indirect session establishment. This multi-functionality allows the system to maintain reliable aggregation sessions while reducing the number of physical ports required.
Solution Approach 2:
The patent creates a logical copy of the direct connection relationship through the daisy chain topology. Even though devices are physically connected in a chain rather than directly to the primary device, the aggregation protocol sessions replicate the behavior of direct connections, maintaining reliability while using fewer ports.
3Adaptability or versatility
If multiple secondary devices are connected via daisy chain topology, then port requirements are reduced and scalability improves, but aggregation protocol session establishment becomes complex
Solution Approach 1:
The primary device serves as an intermediary that simplifies daisy chain session establishment by automatically handling packet forwarding between secondary devices. This mediator approach allows multiple secondary devices to be connected via daisy chain topology without requiring complex peer-to-peer session management between all devices in the chain.

AI summary
Various systems and methods that allow multiple aggregation protocol sessions to be established in a daisy chain network are disclosed. One method involves sending a first aggregation protocol packet and a first session identifier associated therewith to a first network device via a first interface and sending a second aggregation protocol packet and a second session identifier associated therewith to a second network device via the first interface.
