Examples with FlowValidator org.openkilda.wfm.topology.flow.validation.FlowValidator used on opensource projects

Example 1 with FlowValidator

use of org.openkilda.wfm.topology.flow.validation.FlowValidator in project open-kilda by telstra.

the class CrudBolt method handleUpdateRequest.

private void handleUpdateRequest(CommandMessage message, Tuple tuple) throws IOException {
    Flow requestedFlow = ((FlowUpdateRequest) message.getData()).getPayload();
    ImmutablePair<PathInfoData, PathInfoData> path;
    try {
        new FlowValidator(flowCache).checkFlowForEndpointConflicts(requestedFlow);
        path = pathComputer.getPath(requestedFlow, Strategy.COST);
        logger.info("Updated flow path: {}", path);
    } catch (FlowValidationException e) {
        throw new MessageException(message.getCorrelationId(), System.currentTimeMillis(), ErrorType.UPDATE_FAILURE, "Could not update flow", e.getMessage());
    } catch (UnroutablePathException e) {
        throw new MessageException(message.getCorrelationId(), System.currentTimeMillis(), ErrorType.UPDATE_FAILURE, "Could not update flow", "Path was not found");
    }
    ImmutablePair<Flow, Flow> flow = flowCache.updateFlow(requestedFlow, path);
    logger.info("Updated flow: {}", flow);
    FlowInfoData data = new FlowInfoData(requestedFlow.getFlowId(), flow, FlowOperation.UPDATE, message.getCorrelationId());
    InfoMessage infoMessage = new InfoMessage(data, System.currentTimeMillis(), message.getCorrelationId());
    Values topology = new Values(MAPPER.writeValueAsString(infoMessage));
    outputCollector.emit(StreamType.UPDATE.toString(), tuple, topology);
    Values northbound = new Values(new InfoMessage(new FlowResponse(buildFlowResponse(flow)), message.getTimestamp(), message.getCorrelationId(), Destination.NORTHBOUND));
    outputCollector.emit(StreamType.RESPONSE.toString(), tuple, northbound);
}

Example 2 with FlowValidator

use of org.openkilda.wfm.topology.flow.validation.FlowValidator in project open-kilda by telstra.

the class CrudBolt method handleCreateRequest.

private void handleCreateRequest(CommandMessage message, Tuple tuple) throws IOException {
    Flow requestedFlow = ((FlowCreateRequest) message.getData()).getPayload();
    ImmutablePair<PathInfoData, PathInfoData> path;
    try {
        new FlowValidator(flowCache).checkFlowForEndpointConflicts(requestedFlow);
        path = pathComputer.getPath(requestedFlow, Strategy.COST);
        logger.info("Created flow path: {}", path);
    } catch (FlowValidationException e) {
        throw new MessageException(message.getCorrelationId(), System.currentTimeMillis(), ErrorType.CREATION_FAILURE, "Could not create flow", e.getMessage());
    } catch (UnroutablePathException e) {
        throw new MessageException(message.getCorrelationId(), System.currentTimeMillis(), ErrorType.CREATION_FAILURE, "Could not create flow", "Path was not found");
    }
    ImmutablePair<Flow, Flow> flow = flowCache.createFlow(requestedFlow, path);
    logger.info("Created flow: {}", flow);
    FlowInfoData data = new FlowInfoData(requestedFlow.getFlowId(), flow, FlowOperation.CREATE, message.getCorrelationId());
    InfoMessage infoMessage = new InfoMessage(data, System.currentTimeMillis(), message.getCorrelationId());
    Values topology = new Values(MAPPER.writeValueAsString(infoMessage));
    outputCollector.emit(StreamType.CREATE.toString(), tuple, topology);
    Values northbound = new Values(new InfoMessage(new FlowResponse(buildFlowResponse(flow)), message.getTimestamp(), message.getCorrelationId(), Destination.NORTHBOUND));
    outputCollector.emit(StreamType.RESPONSE.toString(), tuple, northbound);
