Performance evaluation of data center service localization based on virtual resource migration in software defined...

Area of Science:

• Optical Networking
• Data Center Interconnection
• Software-Defined Networking (SDN)

Background:

• Data center services require high bandwidth and burstiness, necessitating advanced interconnection solutions.
• Previous work focused on cross-stratum optimization for data center services within optical networks.
• Extending resource optimization to the user side is crucial for enhancing end-to-end quality of service.

Purpose of the Study:

• To propose a novel Data Center Service Localization (DCSL) architecture.
• To enhance end-to-end quality of service by extending data center resources to the user side.
• To introduce a Migration Evaluation Scheme (MES) for the DCSL architecture.

Main Methods:

• Development of a DCSL architecture based on virtual resource migration in a software-defined elastic data center optical network.
• Introduction of a Migration Evaluation Scheme (MES) to assess DCSL performance.
• Experimental verification on an OpenFlow-based enhanced SDN testbed.

Main Results:

• The DCSL architecture enhances responsiveness to dynamic end-to-end demands.
• The proposed scheme effectively reduces blocking probability and optimizes optical network and application resources.
• Experimental validation confirmed the feasibility and efficiency of the DCSL architecture and MES.

Conclusions:

• The DCSL architecture significantly improves end-to-end quality of service for data center services.
• The MES provides a quantitative evaluation of performance under heavy traffic loads, outperforming other schemes.
• This approach offers a globally optimized solution for managing resources in elastic data center optical networks.
