Fields

• daPeerSelectionTargets ∷ PeerSelectionTargets

  selection targets for the peer governor

• daReadLocalRootPeers ∷ STM m (Config RelayAccessPoint)
   
• daReadPublicRootPeers ∷ STM m (Map RelayAccessPoint PeerAdvertise)
   
• daReadUseBootstrapPeers ∷ STM m UseBootstrapPeers
   
• daOwnPeerSharing ∷ PeerSharing

  Peer's own PeerSharing value.

  This value comes from the node's configuration file and is static.

• daReadUseLedgerPeers ∷ STM m UseLedgerPeers
   
• daProtocolIdleTimeout ∷ DiffTime

  Timeout which starts once all responder protocols are idle. If the responders stay idle for duration of the timeout, the connection will be demoted, if it wasn't used by the p2p-governor it will be closed.

  Applies to Unidirectional as well as Duplex node-to-node connections.

  See serverProtocolIdleTimeout.

• daTimeWaitTimeout ∷ DiffTime

  Time for which node-to-node connections are kept in TerminatingState, it should correspond to the OS configured TCP TIME_WAIT timeout.

  This timeout will apply to after a connection has been closed, its purpose is to be resilient for delayed packets in the same way TCP is using TIME_WAIT.

• daDeadlineChurnInterval ∷ DiffTime

  Churn interval between churn events in deadline mode. A small fuzz is added (max 10 minutes) so that not all nodes churn at the same time.

  By default it is set to 3300 seconds.

• daBulkChurnInterval ∷ DiffTime

  Churn interval between churn events in bulk sync mode. A small fuzz is added (max 1 minute) so that not all nodes churn at the same time.

  By default it is set to 300 seconds.

Fields

• acceptedConnectionsHardLimit ∷ !Word32

  Hard limit of accepted connections.

• acceptedConnectionsSoftLimit ∷ !Word32

  Soft limit of accepted connections. If we are above this threshold, we will start rate limiting.

• acceptedConnectionsDelay ∷ !DiffTime

  Max delay for limiting accepted connections. We use linear regression starting from 0 at the soft limit up to acceptedConnectionDelay at the hard limit.

Fields

• daRethrowPolicy ∷ RethrowPolicy
