Types

type Config added in v0.22.0

type Config struct {
	ExternalAddress string        `user:"true" help:"the public address of the node, useful for nodes behind NAT" default:""`
	Timeout         time.Duration `help:"timeout for pinging storage nodes" default:"10m0s" testDefault:"1m"`

	RateLimitInterval  time.Duration `help:"the amount of time that should happen between contact attempts usually" releaseDefault:"10m0s" devDefault:"1ns"`
	RateLimitBurst     int           `help:"the maximum burst size for the contact rate limit token bucket" releaseDefault:"2" devDefault:"1000"`
	RateLimitCacheSize int           `help:"the number of nodes or addresses to keep token buckets for" default:"1000"`
}

Config contains configurable values for contact service.

type Endpoint

type Endpoint struct {
	pb.DRPCNodeUnimplementedServer
	// contains filtered or unexported fields
}

Endpoint implements the contact service Endpoints.

func NewEndpoint

func NewEndpoint(log *zap.Logger, service *Service) *Endpoint

NewEndpoint returns a new contact service endpoint.

func (*Endpoint) CheckIn

func (endpoint *Endpoint) CheckIn(ctx context.Context, req *pb.CheckInRequest) (_ *pb.CheckInResponse, err error)

CheckIn is periodically called by storage nodes to keep the satellite informed of its existence, address, and operator information. In return, this satellite keeps the node informed of its reachability. When a node checks-in with the satellite, the satellite pings the node back to confirm they can successfully connect.

func (*Endpoint) GetTime added in v0.30.0

func (endpoint *Endpoint) GetTime(ctx context.Context, req *pb.GetTimeRequest) (_ *pb.GetTimeResponse, err error)

GetTime returns current timestamp.

type RateLimiter added in v1.29.4

type RateLimiter struct {
	// contains filtered or unexported fields
}

RateLimiter allows to prevent multiple events in fixed period of time.

func NewRateLimiter added in v1.29.4

func NewRateLimiter(interval time.Duration, burst, numLimits int) *RateLimiter

NewRateLimiter is a constructor for RateLimiter.

func (*RateLimiter) IsAllowed added in v1.29.4

func (rateLimiter *RateLimiter) IsAllowed(key string) bool

IsAllowed indicates if event is allowed to happen.

type Service

type Service struct {
	// contains filtered or unexported fields
}

Service is the contact service between storage nodes and satellites. It is responsible for updating general node information like address and capacity. It is also responsible for updating peer identity information for verifying signatures from that node.

architecture: Service

func NewService

func NewService(log *zap.Logger, self *overlay.NodeDossier, overlay *overlay.Service, peerIDs overlay.PeerIdentities, dialer rpc.Dialer, config Config) *Service

NewService creates a new contact service.

func (*Service) Close added in v0.22.0

func (service *Service) Close() error

Close closes resources.

func (*Service) Local added in v0.22.0

func (service *Service) Local() overlay.NodeDossier

Local returns the satellite node dossier.

func (*Service) PingBack added in v0.29.0

func (service *Service) PingBack(ctx context.Context, nodeurl storj.NodeURL) (_ bool, _ bool, _ string, err error)

PingBack pings the node to test connectivity.
