RSC: Enabling High-Performance RDMA for Serverless Services with Adaptive Network Multiplexing
Serverless functions are short-lived, yet RDMA Reliable Connections (RCs) are expensive to create and assume long-lived endpoints. Even when compute sandboxes are warm, an invocation can still suffer a network-cold start if it establishes a new RC or accesses a remote endpoint for the first time. We present RSC (Reliab...
