Example 1 with SDNControllerClient

use of nl.uva.cs.lobcder.optimization.SDNControllerClient in project lobcder by skoulouzis.

the class WebDataFileResource method getLowestCostWorker.

private String getLowestCostWorker(String reqSource) throws IOException, URISyntaxException, InterruptedException {
    if (sdnClient == null) {
        String uri = PropertiesHelper.getSDNControllerURL();
        sdnClient = new SDNControllerClient(uri);
    }
    List<DefaultWeightedEdge> shortestPath = sdnClient.getShortestPath(reqSource, workersMap.keySet());
    Logger.getLogger(WebDataFileResource.class.getName()).log(Level.FINEST, "getShortestPath: {0}", shortestPath);
    if (PropertiesHelper.pushFlow()) {
        sdnClient.pushFlow(shortestPath);
    }
    DefaultWeightedEdge e = shortestPath.get(0);
    String[] workerSwitch = e.toString().split(" : ");
    String workerIP = workerSwitch[0].substring(1);
    String worker = workersMap.get(workerIP);
    String w = worker + "/" + getLogicalData().getUid();
    String token = UUID.randomUUID().toString();
    AuthLobcderComponents.setTicket(worker, token);
    // w = "http://localhost:8080/lobcder-worker/"+getLogicalData().getUid();
    return w + "/" + token;
