Types

type Topology

type Topology struct {
	// Information is the toplogy information.
	Information TopologyInformation

	// Requests aggregates all the incoming requests received by the handler.
	// If it is not initialized, nothing is reported.
	Requests metrics.Counter
}

Topology implements a service discovery server based on the topology information.

func (Topology) Gateways

func (t Topology) Gateways(ctx context.Context,
	_ *dpb.GatewaysRequest) (*dpb.GatewaysResponse, error)

Gateways discovers gateways in this topology.

func (Topology) HiddenSegmentServices

func (t Topology) HiddenSegmentServices(ctx context.Context,
	_ *dpb.HiddenSegmentServicesRequest) (*dpb.HiddenSegmentServicesResponse, error)

HiddenSegmentServices discovers hidden segment services in this topology.

func (Topology) RequestsLabels

func (t Topology) RequestsLabels() []string

RequestsLabels exposes the labels required by the Requests metric.

type TopologyInformation

type TopologyInformation interface {
	// Gateways returns all the Gateways in the AS.
	Gateways() ([]topology.GatewayInfo, error)
	// HiddenSegmentLookupAddresses returns the addresses of the hidden segment
	// lookup services.
	HiddenSegmentLookupAddresses() ([]*net.UDPAddr, error)
	// HiddenSegmentRegistrationAddresses returns the addresses of the hidden
	// segment registration services.
	HiddenSegmentRegistrationAddresses() ([]*net.UDPAddr, error)
}

TopologyInformation provides the discovery service with topology information.
