Connection Migrator for Dynamic Network Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network load balancing techniques rely on round-robin distribution of connection requests, which is inefficient and does not consider the dynamic conditions of servers or the nature of incoming connections, leading to suboptimal resource utilization and potential bottlenecks.
Innovation Solution
Implementing a connection migrator that compiles protocol state, aggregates it with data, and migrates connections to optimize resource allocation, along with a tunneler that uses encapsulation mapping to manage packets and de-encapsulate them for efficient routing, while considering host status and session information for informed load balancing decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If round-robin distribution is used for connection requests, then implementation simplicity is maintained, but resource utilization efficiency deteriorates
Solution Approach 1:
The load balancing system transitions from static round-robin distribution to dynamic connection migration based on real-time server status. The connection migrator continuously monitors server health and load conditions, then dynamically redirects connections to optimize resource utilization while maintaining system simplicity through automated decision-making algorithms.
2Productivity
If connection migration with state compilation is implemented, then resource allocation optimization is achieved, but system complexity increases
Solution Approach 1:
The system separates connection management functions into distinct modules: the connection migrator handles connection redirection decisions, while the protocol state compiler manages state aggregation and tunneling. This segmentation allows each component to specialize in specific tasks, optimizing resource allocation without requiring complete system redesign.
Solution Approach 2:
The protocol state compiler acts as an intermediary between the connection migrator and target servers. It compiles connection state information and aggregates it into tunnelable formats, enabling efficient connection migration while abstracting the complexity from the decision-making layer.
3Productivity
If tunneling is used for connection migration, then connection state transfer efficiency is improved, but protocol complexity increases
Solution Approach 1:
The system changes the parameter representation of connection state by compiling protocol-specific state information into standardized, tunnelable formats. This parameter transformation enables efficient transmission of connection state through tunneling mechanisms while maintaining compatibility across different protocols through systematic state aggregation.

AI summary
In an exemplary device implementation, a device includes: a connection migrator that is configured to migrate connections away from the device; the connection migrator capable of precipitating a compilation of protocol state for a connection across a protocol stack; the connection migrator adapted to aggregate the compiled protocol state with data for the connection into an aggregated connection state; the connection migrator further capable of causing the aggregated connection state to be sent toward a target device. In an exemplary media implementation, processor-executable instructions direct a device to perform actions including: obtaining at least a portion of a source/destination pair from a packet; accessing an encapsulation mapping table using the at least a portion of the source/destination pair to locate an encapsulation mapping entry; extracting a flow identifier from the encapsulation mapping entry; and replacing part of the packet with the flow identifier to produce an encapsulated packet.
