Types

type UDP 

type UDP struct{}

UDP implements greet.TransportLayer for UDP probes. Because UDP is connectionless, Dial sends an empty datagram and waits for any response to capture RTT. The returned conn is the live UDPConn; since no app layers run over UDP today the engine closes it immediately after Dial.

func New added in v1.0.3 

func New() *UDP

New creates a new UDP transport layer.

func (*UDP) DefaultPort 

func (u *UDP) DefaultPort() int

func (*UDP) Dial added in v1.0.3 

func (u *UDP) Dial(ctx context.Context, start time.Time, host string, port int) (net.Conn, time.Duration, time.Duration, error)

Dial resolves host, sends an empty datagram, waits for a response, and returns the UDPConn together with TTDR and RTT. RTT is the send→receive round trip. The caller is responsible for closing the returned conn.

func (*UDP) Name 

func (u *UDP) Name() string

func (*UDP) Transport 

func (u *UDP) Transport() greet.Transport
