Abstract
Certain features and aspects provide a proxy for a node in a cloud computing cluster that holds the packet used by a remote client to initiate a connection until a backend server is ready. When the user space controller receives the packet, it notifies the server that a connection is being established and holds the packet until the proxy receives a notification that the server is ready. The user space controller of the proxy then writes routing information to memory so that kernel space is used for the connection traffic going forward, and reinjects the packet into the networking layer of the cluster. Subsequent packets, including any acknowledgement packet that is part of the initial handshake, will flow through kernel space without involvement of the user space controller and be processed more efficiently than would be possible using user space.
