Abstract: Techniques are provided for passive management of network connections. In an example, a cluster node determines to migrate its client connections to other nodes of its cluster. The cluster node can determine whether a client implements an always resolving policy (regarding resolving a domain name of the cluster), a cache resolving policy, or a resolve once policy. Where the node disconnects a client and it does not reconnect (because a domain name service (DNS) server no longer resolves a domain name to the node), the client implements an always resolving policy. Where the node eventually stops reconnecting, the client implements a cache resolving policy. After nodes of those types are migrated, nodes that implement a resolve once policy. The node can migrate these clients by disconnecting them in coordinating with stopping accepting connections. This can lead to non-disruptive migration of all clients.
