Constants used by the locate service, clients, and target servers accepting access tokens issued by the locate service.

Variables

var Configs = map[string]Ports{
	"ndt/ndt7": {
		URL("ws", "", "/ndt/v7/upload"),
		URL("ws", "", "/ndt/v7/download"),
		URL("wss", "", "/ndt/v7/upload"),
		URL("wss", "", "/ndt/v7/download"),
	},
	"ndt/ndt5": {

		URL("ws", ":3001", "/ndt_protocol"),
		URL("wss", ":3010", "/ndt_protocol"),
	},
	"neubot/dash": {
		URL("https", "", "/negotiate/dash"),
	},
	"wehe/replay": {
		URL("wss", ":4443", "/v0/envelope/access"),
	},
	"iperf3/test": {
		URL("wss", "", "/v0/envelope/access"),
	},
}

Configs is a temporary, static mapping of service names and their set of associated ports. Ultimately, this will be discovered dynamically as service heartbeats register with the locate service.

var Countries = map[string]string{}/* 244 elements not displayed */

Countries contains a static mapping of two-letter country codes to their geographic center. Source: https://developers.google.com/public-data/docs/canonical/countries_csv

var LegacyServices = map[string]string{
	"neubot/dash": "neubot",
	"wehe/replay": "wehe",
	"iperf3/test": "ndt7",
	"ndt/ndt5":    "ndt_ssl",
	"ndt/ndt7":    "ndt7",
}

LegacyServices associates legacy mlab-ns experiment target names with their v2 equivalent.

var Regions = map[string]string{}/* 4416 elements not displayed */

Regions contains a static mapping of ISO 3166-2 region codes. Each key is additionally prefixed with the two-letter country code because not all region codes are unique.

var ServiceParams = map[string]float64{
	EarlyExitParameter:      0.9,
	MaxCwndGainParameter:    1,
	MaxElapsedTimeParameter: 1,
}

ServiceParams is a map of common parameters passed in by services (as URL params) with corresponding probabilities set by the Locate.

Functions
