Abstract: A Virtual Private Cloud (VPC) that enables both RDMA and TCP provides advantages for both tenants and cloud providers. In this study, we introduce Jakiro, an innovative framework of vNIC design that supports both RDMA and TCP over a unified VPC. Jakiro holds the capability to support fundamental VPC features for both RDMA and TCP streams while maintaining compatibility with applications and intra-host RDMA optimization techniques. Our test results indicate that Jakiro introduces negligible overhead.
