Play the recording: ByteDance Jakiro: Enabling RDMA and TCP over Virtual Private Cloud

Why: Carrying RDMA and TCP over one VPC overlay with real VPC semantics (security groups, QoS) is a concrete cloud-native multi-tenancy problem.

What: A vNIC design supporting both RDMA and TCP inside a VPC with QoS and security-group enforcement, near-physical RDMA performance, deployed a year in production.

How: A unified vNIC framework that applies VPC features to both stream types while staying compatible with intra-host RDMA optimizations and guaranteeing weighted-fair QoS between RDMA and TCP.

Where applicable: ByteDance-specific production VPC; the dual-stack-over-one-overlay pattern transfers, the deployment specifics don't.
