type DelayConfig ¶ added in v1.6.1
type DelayConfig struct { // InitialReconnectDelay is the minimum amount of time the node will delay a // reconnection to a peer. This value is used to start the exponential // backoff.

type HealthConfig ¶ added in v1.2.1
type HealthConfig struct { // Marks if the health check should be enabled Enabled bool `json:"-"` // MinConnectedPeers is the minimum number of peers that the network should // be connected to to be considered healthy. MinConnectedPeers uint `json:"minConnectedPeers"` // MaxTimeSinceMsgReceived is the maximum amount of time since the network // last received a message to be considered healthy.

HealthConfig describes parameters for network layer health checks.
type Network ¶
type Network interface { // All consensus messages can be sent through this interface. Thread safety // must be managed internally in the network. sender.ExternalSender // Has a health check health.Checker peer.Network // StartClose this network and all existing connections it has. Calling // StartClose multiple times is handled gracefully. StartClose() // Should only be called once, will run until either a fatal error occurs, // or the network is closed. Dispatch() error // WantsConnection returns true if this node is willing to attempt to // connect to the provided nodeID. If the node is attempting to connect to // the minimum number of peers, then it should only connect if the peer is a // validator or beacon. WantsConnection(ids.NodeID) bool // Attempt to connect to this IP. The network will never stop attempting to // connect to this ID. ManuallyTrack(nodeID ids.NodeID, ip ips.IPPort) // PeerInfo returns information about peers. If [nodeIDs] is empty, returns // info about all peers that have finished the handshake. Otherwise, returns // info about the peers in [nodeIDs] that have finished the handshake. PeerInfo(nodeIDs []ids.NodeID) []peer.Info // NodeUptime returns given node's [subnetID] UptimeResults in the view of // this node's peer validators. NodeUptime(subnetID ids.ID) (UptimeResult, error) }
Network defines the functionality of the networking library.
func NewNetwork ¶
func NewNetwork( config *Config, msgCreator message.Creator, metricsRegisterer prometheus.Registerer, log logging.Logger, listener net.Listener, dialer dialer.Dialer, router router.ExternalHandler, ) (Network, error)
NewNetwork returns a new Network implementation with the provided parameters.

ReadHandshakeTimeout time.Duration `json:"readHandshakeTimeout"` }
type UptimeResult ¶ added in v1.7.0
type UptimeResult struct { // RewardingStakePercentage shows what percent of network stake thinks we're // above the uptime requirement. RewardingStakePercentage float64 // WeightedAveragePercentage is the average perceived uptime of this node, // weighted by stake. // Note that this is different from RewardingStakePercentage, which shows // the percent of the network stake that thinks this node is above the // uptime requirement. WeightedAveragePercentage is weighted by uptime. // i.e If uptime requirement is 85 and a peer reports 40 percent it will be // counted (40*weight) in WeightedAveragePercentage but not in // RewardingStakePercentage since 40 < 85 WeightedAveragePercentage float64 }
