Packet Flow Optimization for Virtualized Server Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual server rack systems lack a single governing entity to manage and optimize packet flow across diverse hardware and software components with different operating systems, leading to inefficiencies in network resource management and traffic control.
Innovation Solution
Implementing a system-level governing framework that monitors and manages both virtual and physical infrastructure components, adjusting packet flow paths based on temporary events by identifying sources and destinations, and optimizing routing resources through Quality-of-Service policies and equal-cost multi-path hash algorithms.

Engineering Contradiction Analysis
1Productivity
If a system-level governing framework is implemented to manage packet flow across diverse hardware and software components, then packet flow efficiency and network resource management are improved, but device complexity and system integration requirements increase
Solution Approach 1:
The patent introduces a system-level governing framework that acts as an intermediary entity between diverse hardware components and software components with different operating systems. This framework provides a unified interface and coordination mechanism, enabling efficient packet flow management without requiring direct integration between all system components, thus improving productivity while managing complexity through abstraction.
2Productivity
If packet flow paths are dynamically adjusted based on temporary events like VM migrations, then network performance and resource utilization are improved, but system stability and control complexity increase
Solution Approach 1:
The patent implements dynamic adjustment of packet flow paths based on temporary events such as virtual machine migrations. The system continuously monitors system state and adapts routing decisions in real-time, allowing network performance to be optimized during dynamic conditions while maintaining the ability to return to stable configurations when events conclude.
Solution Approach 2:
The governing framework incorporates feedback mechanisms that monitor packet flow conditions, system events, and performance metrics. This feedback enables the system to detect temporary events like VM migrations and automatically adjust packet flow paths accordingly, improving network performance while maintaining stability through continuous monitoring and adaptive response.
3Productivity
If Quality-of-Service policies and equal-cost multi-path hash algorithms are used to optimize routing, then traffic prioritization and resource allocation are improved, but device complexity and computational overhead increase
Solution Approach 1:
The patent employs Quality-of-Service policies that modify routing parameters based on traffic characteristics and system conditions. By changing parameters such as priority levels, bandwidth allocations, and hash algorithm selections dynamically, the system optimizes resource allocation efficiency without requiring fundamentally complex routing logic, leveraging parameter adjustment rather than structural complexity.

AI summary
Methods, apparatus, systems, and articles of manufacture are disclosed. An example apparatus includes a packet analyzer to determine that a first virtualized server is preparing to migrate to a second virtualized server based on a data packet, a packet flow path generator to identify a set of network switches between the first virtualized server and the second virtualized server when the first virtualized server is in a different rackmount server than the second virtualized server, and a policy adjustor to adjust a policy of one or more network switches in the set to prioritize a packet flow corresponding to the migration.
