Constants

const GrpcBasePort = 5150

GrpcBasePort - the base port for trafficsim - other e2 ports are stepped from this

const ImsiBaseCbrs = types.Imsi(315010999900000)

ImsiBaseCbrs - from https://imsiadmin.com/cbrs-assignments

const ServiceName = "ran-simulator"

ServiceName is the default name of this Kubernetes service

const TestPlmnID = "315010"

Functions

func AspectRatio

func AspectRatio(point *types.Point) float64

AspectRatio - Compensate for the narrowing of meridians at higher latitudes

func AzimuthToRads

func AzimuthToRads(azimuth float64) float64

AzimuthToRads - angle measured in degrees clockwise from north, expressed in rads from 3 o'clock anticlockwise

func DegreesToRads

func DegreesToRads(degrees float64) float64

DegreesToRads - general conversion of degrees to rads, both starting at 3 o'clock going anticlockwise

func GetRotationDegrees

func GetRotationDegrees(pointA *types.Point, pointB *types.Point) float64

GetRotationDegrees - get the rotation of the car

func ImsiGenerator

func ImsiGenerator(ueIdx int) types.Imsi

ImsiGenerator -- generate an Imsi from an index

func ParseGNMIElements

func ParseGNMIElements(elms []string) (*pb.Path, error)

ParseGNMIElements builds up a gnmi path, from user-supplied text

func RandomColor

func RandomColor() string

RandomColor from https://htmlcolorcodes.com/

func RandomLatLng

func RandomLatLng(mapCenterLat float64, mapCenterLng float64, radius float64, aspectRatio float64) types.Point

RandomLatLng - Generates a random latlng value in 1000 meter radius of loc

func SplitPath

func SplitPath(path string) []string

SplitPath splits a gnmi path according to the spec. See https://github.com/openconfig/reference/blob/master/rpc/gnmi/gnmi-path-conventions.md No validation is done. Behavior is undefined if path is an invalid gnmi path. TODO: Do validation?

func SplitPaths

func SplitPaths(paths []string) [][]string

SplitPaths splits multiple gnmi paths

func StrPath

func StrPath(path *pb.Path) string

StrPath builds a human-readable form of a gnmi path. e.g. /a/b/c[e=f]

func StrPathElem

func StrPathElem(pathElem []*pb.PathElem) string

StrPathElem builds a human-readable form of a list of path elements. e.g. /a/b/c[e=f]

func StrVal

func StrVal(val *pb.TypedValue) string

StrVal will return a string representing the supplied value

Types

type ServerParams

type ServerParams struct {
	CaPath         string
	KeyPath        string
	CertPath       string
	TopoEndpoint   string
	AddK8sSvcPorts bool
}

ServerParams - params to start a new server
