Abstract: Distributed network address discovery in non-uniform node networks can be performed. Regarding a client request for a service, network management component (NMC) can determine a network address space associated with a client based on a network identifier associated with the client or a node identifier. NMC can determine a group of candidate nodes (CN group) from a group of nodes based on network addresses associated with nodes of the node group and the network address space. NMC can determine a group of available candidate nodes (ACN group), from the CN group, available and able to process the request and perform the service based on operational statuses associated with the nodes of the CN group or services associated with those nodes. From the ACN group, NMC can determine a ranked list of network addresses associated with available nodes that can process the request based on defined service performance criteria.

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.
