Aggregated Tunnel Routing for Network Packet Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting information packets through network nodes do not effectively distribute packets based on their specific requirements, such as network performance and reliability, leading to inefficient use of tunnel resources.
Innovation Solution
The establishment of aggregated tunnels between network nodes, where information packets are routed based on profile conditions and policies that consider factors like source and destination addresses, payload, and Quality-of-Service (QoS) requirements, allowing for selective routing through multiple tunnels to optimize network performance.

1Productivity
If information packets are sent indiscriminately through multiple tunnels, then the network infrastructure is utilized, but network performance and reliability are not optimized for different packet requirements
Solution Approach 1:
The patent applies local quality by assigning different characteristics to different tunnels within the aggregated tunnel group. Each tunnel is configured with specific profile conditions (QoS requirements, bandwidth capabilities, latency characteristics) that make it suitable for specific types of traffic. This allows information packets with different requirements to be routed through tunnels that locally match their needs, optimizing both throughput and reliability for each packet type.
Solution Approach 2:
The patent segments the network traffic into different categories based on profile conditions and routes each segment through appropriate tunnels. By dividing the traffic flow and tunnel resources into manageable segments with specific characteristics, the system can optimize performance and reliability for each segment independently rather than treating all traffic uniformly.
2Productivity
If multiple aggregated tunnels are established to improve network capacity, then more paths are available for data transmission, but the complexity of managing and selecting appropriate tunnels increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring profile conditions and policies for each tunnel before runtime. The system evaluates packet characteristics against these pre-defined profiles and selects appropriate tunnels based on matching criteria. This preliminary setup automates the tunnel selection process, reducing the operational complexity of managing multiple aggregated tunnels while maintaining high data transmission capacity.
Solution Approach 2:
The system implements self-service by enabling automated tunnel selection based on packet characteristics and pre-configured policies. The network node independently evaluates each information packet against the profile conditions of available tunnels and selects the most appropriate tunnel without manual intervention, thereby managing multiple aggregated tunnels efficiently without increasing operational complexity.
3Productivity
If tunnel bandwidth weighting is adjusted dynamically to optimize throughput, then aggregate tunnel performance improves, but the ability to distribute packets according to specific packet requirements is lost
Solution Approach 1:
The patent applies dynamics by enabling both dynamic bandwidth weighting adjustment and dynamic packet routing selection. The system can adjust tunnel bandwidth weights in response to changing network conditions while simultaneously evaluating each information packet's requirements against profile conditions to select the most appropriate tunnel. This dynamic approach allows the system to optimize aggregate throughput while maintaining packet-specific routing flexibility.

AI summary
The present invention discloses methods and systems for sending information packets from a first network node to a second network node. An aggregated tunnel is established between the first network node and the second network node. An information packet is determined whether to be sent according to profile condition(s) of the aggregated tunnel and then according to a selected policy. When a selected policy is selected and the information packet is sent through a tunnel according to the selected policy. When no policy is selected, the information packet is sent through one of a first group of tunnels. When no profile is selected, the information packet is sent through a network interface of the first network node.
