New Connection Ownership
When a new connection is directed to a node of the cluster via load balancing, that node owns both directions of the connection. If any connection packets arrive at a different node, they are forwarded to the owner node over the cluster control link. If a reverse flow arrives at a different node, it is redirected back to the original node.
Traffic redirection is not supported in this release. When a new connection is directed to a node of the cluster via load balancing, that node owns both directions of the connection. All the subsequent packets for the same connection should arrive the same node. If any connection packets arrive at a different node, they will be dropped. If a reverse flow arrives at a different node, it will be dropped as well. For centralized features, if the connections do not arrive on the control node, they will be dropped.
By default, AWS GWLB uses 5-tuple to maintain flow stickiness. It is recommended to enable 2-tuple or 3-tuple stickiness on AWS GWLB to ensure the same flows are sent to the same node.
