VXLAN-Based BGP EVPN Architecture for Dynamic and Flexible Workflow Deployment in Multi-Vendor Supercomputing Environments

The increasing prevalence of streaming workflows in scientific supercomputing environments presents significant challenges for network scalability, resource orchestration, and overall system design. This paper introduces the use of a VXLAN-based BGP EVPN architecture for organizing large-scale supercomputing data center networks as software-defined networks (SDNs). The VXLAN-based BGP EVPN architecture offers flexibility and scalability for deploying and orchestrating streaming workflows with varying resource demands. We have prototyped a testbed of software-defined networks using this architecture to facilitate the development of network orchestration mechanisms capable of quickly adapting to the dynamic resource demands of streaming workflows. Our initial experimental results demonstrate the testbed’s potential to achieve high network throughput, scalable design, and balanced resource utilization in streaming workflow scenarios across multiple vendors. These findings suggest that our approach of constructing SDNs with a VXLAN-based BGP EVPN architecture has offered a viable solution to the evolving networking demands of modern supercomputing facilities.
