Examples with UDPTransport net.i2p.router.transport.udp.UDPTransport used on opensource projects

Example 1 with UDPTransport

use of net.i2p.router.transport.udp.UDPTransport in project i2p.i2p by i2p.

the class CommSystemFacadeImpl method notifyReplaceAddress.

/**
 * UDP changed addresses, tell NTCP and restart
 *
 * All the work moved to NTCPTransport.externalAddressReceived()
 *
 * @param udpAddr may be null; or udpAddr's host/IP may be null
 */
@Override
public void notifyReplaceAddress(RouterAddress udpAddr) {
    byte[] ip = null;
    int port = 0;
    // we probably shouldn't, see UDPTransport rebuildExternalAddress() TODO
    if (udpAddr != null && udpAddr.getOption("ihost0") == null) {
        ip = udpAddr.getIP();
        port = udpAddr.getPort();
    }
    if (port < 0) {
        Transport udp = _manager.getTransport(UDPTransport.STYLE);
        if (udp != null)
            port = udp.getRequestedPort();
    }
    if (ip != null || port > 0)
        _manager.externalAddressReceived(Transport.AddressSource.SOURCE_SSU, ip, port);
    else
        notifyRemoveAddress(false);
}

Example 2 with UDPTransport

use of net.i2p.router.transport.udp.UDPTransport in project i2p.i2p by i2p.

the class TransportManager method configTransports.

private void configTransports() {
    boolean enableUDP = _context.getBooleanPropertyDefaultTrue(PROP_ENABLE_UDP);
    Transport udp = null;
    if (enableUDP) {
        udp = new UDPTransport(_context, _dhThread);

        if (udp != null) {
            // pass along the port SSU is probably going to use
            // so that NTCP may bind early
            int port = udp.getRequestedPort();
            if (port > 0)
