DCI Routing Information Filtering to Reduce Redundant Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data center interconnection (DCI) solutions waste transmission, memory, and computing resources due to unnecessary transmission of routing information and lack of effective filtering at the sending and receiving ends.
Innovation Solution
Implement routing information filtering by pre-planning DCI interworking instances in DCI devices and adding DCI identifiers to interworking route targets, ensuring only relevant routing information is sent to peer devices, thereby reducing redundant transmissions and resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the DCI device sends all received routing information to the peer DCI device, then routing information is transmitted to ensure DCI forwarding, but transmission resources are wasted and memory resources and computing resources of the peer DCI device are wasted
Solution Approach 1:
The patent extracts and removes unnecessary routing information from the transmission process by introducing a filtering mechanism at the DCI device. The system identifies and sends only the essential routing information related to DCI forwarding instances to the peer DCI device, while discarding redundant routing information that does not contribute to DCI forwarding functionality. This extraction principle directly addresses the resource waste issue while maintaining reliable DCI forwarding.
Solution Approach 2:
The patent applies local quality by differentiating the treatment of different routing information based on its relevance to DCI forwarding. The system selectively processes and transmits only the routing information that is locally relevant to DCI forwarding instances, while ignoring routing information that is not needed for DCI forwarding. This selective approach optimizes resource utilization while ensuring reliable DCI forwarding.

This extraction principle directly addresses the resource waste issue while maintaining reliable DCI forwarding.
Solution Approach 2:
The patent applies preliminary action by pre-configuring filtering criteria at the DCI device before routing information transmission. The system pre-establishes the logic to identify and filter routing information related to DCI forwarding instances, so that when routing information is received, the filtering action is performed automatically without requiring complex real-time processing. This preliminary preparation reduces the computational burden on the peer DCI device while ensuring reliable DCI forwarding.
3Adaptability or versatility
If routing information is transmitted without filtering, then all routing information is forwarded, but redundant routing information is transmitted causing resource waste
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different routing information based on its relevance to DCI forwarding. The system selectively processes and transmits only the routing information that is locally relevant to DCI forwarding instances, while ignoring routing information that is not needed for DCI forwarding. This selective approach optimizes resource utilization while ensuring reliable DCI forwarding.
Solution Approach 2:
The patent changes the parameter of routing information transmission by introducing a filtering mechanism that modifies which routing information is transmitted. The system alters the transmission process to send only routing information that meets specific criteria (related to DCI forwarding instances), thereby changing the characteristics of transmitted data from all routing information to filtered routing information, reducing resource waste while maintaining functionality.
Data Source
AI summary
A first data center interconnection (DCI) device in a first data center receives a first packet from a Border Gateway Protocol Ethernet virtual private network (BGP EVPN) neighbor, where the first packet includes routing information of a first forwarding instance of an access device in the first data center and an export route target of the first forwarding instance. The first DCI device obtains a second forwarding instance that corresponds to the first packet, where an import route target of the second forwarding instance matches the export route target of the first forwarding instance. The first DCI device generates a second packet that includes routing information of the second forwarding instance and an export route target of the second forwarding instance, which includes a DCI interworking route target. The first DCI device sends the second packet to a second DCI device in a second data center.
