## Package net.corda.node.services.network

### Types

AbstractNetworkMapService | `abstract class AbstractNetworkMapService : NetworkMapService, AbstractNodeService` Abstracted out core functionality as the basis for a persistent implementation, as well as existing in-memory implementation.
InMemoryNetworkMapCache | `open class InMemoryNetworkMapCache : SingletonSerializeAsToken, NetworkMapCache` Extremely simple in-memory cache of the network map.
InMemoryNetworkMapService | `class InMemoryNetworkMapService : AbstractNetworkMapService`
LastAcknowledgeInfo | `data class LastAcknowledgeInfo`
NetworkMapService | `interface NetworkMapService` A network map contains lists of nodes on the network along with information about their identity keys, services they provide and host names or IP addresses where they can be connected to. This information is cached locally within nodes, by the NetworkMapCache. Currently very basic consensus controls are applied, using signed changes which replace each other based on a serial number present in the change.
NodeRegistration | `class NodeRegistration` A node registration state in the network map.
NodeRegistrationInfo | `data class NodeRegistrationInfo`
PersistentNetworkMapService | `class PersistentNetworkMapService : AbstractNetworkMapService` A network map service backed by a database to survive restarts of the node hosting it.
WireNodeRegistration | `class WireNodeRegistration : SignedData<NodeRegistration>` A node registration and its signature as a pair.

### Exceptions

NodeMapError | `sealed class NodeMapError : Exception`
