RDS-over-TCP: More Than Just Cluster IPC - Sowmini Varadhan, Oracle

The Reliable Datagram Socket (RDS) is a an attractive IPC model for Distributed Computing environments such as Clusters and Cloud datacenters because it is designed to be transport-independant (works transparently over both InfiniBand and ethernet), fully scalable (N nodes can be a fully connected mesh with just O(N) connections instead of N * N TCP
connections) and accesible via a simple POSIX based API.

RDS implements layered kernel sockets that tunnels payloads over TCP, and has parallels with other Cloud encaps methods like VXLANand has potential to share common socket abstractions. RDS over TCP is currently available in Linux and we are currently considering extensions such as QoS to this feature.

The objective of this proposal is to give some exposure to what RDS-TCP supports today, and stimulate some discussion getting some common shareable abstractions.
