Pseudo Wire Load Sharing via Trunk Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies do not support pseudo wire (PW) load sharing, limiting the ability to effectively transmit large data traffic and failing to combine bandwidths for enhanced throughput.
Innovation Solution
A method and device for PW load sharing, where a first provider edge (PE) device connects to multiple second PE devices using multiple PWs, allowing for load sharing processing by forwarding data flows through a PW trunk interface associated with multiple active PWs, thereby increasing bandwidth and throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single PW is used for data transmission, then the PW provides stable and simple connectivity, but the bandwidth and throughput are limited and cannot handle large data traffic
Solution Approach 1:
The patent segments the data flow by dividing it into multiple portions and forwarding different portions through different PWs simultaneously. The PE device performs load sharing processing to split the incoming data flow and distribute it across multiple active PWs, thereby increasing overall transmission capacity while maintaining individual PW simplicity
Solution Approach 2:
The patent merges multiple PWs into a unified load-sharing system. By associating multiple active PWs with a single PE device and implementing load sharing at the PE device level, the system combines the bandwidth of multiple PWs to handle large data traffic while presenting a simplified interface to end users
2Productivity
If multiple PWs are used for load sharing, then the bandwidth and throughput increase, but the PW configuration and management become more complex
Solution Approach 1:
The PE device is designed with multi-functionality to handle multiple active PWs simultaneously. It can perform load sharing processing, divide data flows, and manage multiple PW associations through a unified mechanism, making the complex multi-PW system easier to operate and manage while maintaining high bandwidth and throughput
3Adaptability or versatility
If PW load sharing is not supported, then the PW configuration remains simple, but the ability to transmit large data traffic is limited
Solution Approach 1:
The patent introduces dynamic load sharing capabilities where the PE device can dynamically divide and distribute data flows across multiple active PWs based on current network conditions and traffic requirements. This dynamic approach enhances adaptability to different data traffic patterns while maintaining efficient data transmission through automated load balancing

AI summary
This application provides a pseudo wire load sharing method and apparatus, applied to a scenario in which a first provider edge PE device is separately connected to at least one second PE device by using at least two PWs. The method comprises: receiving, by the first PE device, a data flow from a customer edge CE device, and forwarding the data flow to a PW trunk trunk interface, where the PW trunk interface is associated with at least two active PWs; and performing, by the first PE device, load sharing processing on the data flow, and forwarding the data flow by using the at least two active PWs. This is beneficial to transmission of large data traffic by using the PW.
