Example 5 with DiscoveryNode

use of org.openkilda.messaging.model.DiscoveryNode in project open-kilda by telstra.

the class DiscoveryManager method handlePortUp.

public void handlePortUp(String switchId, String portId) {
    DiscoveryNode subject;
    Node node = new Node(switchId, portId);
    List<DiscoveryNode> subjectList = filterQueue(node);
    if (subjectList.size() != 0) {
        // Similar to SwitchUp, if we have a PortUp on an existing port, either we are receiving
        // a duplicate, or we missed the port down, or a new discovery has occurred.
        // NB: this should cause an ISL discovery packet to be sent.
        // TODO: we should probably separate "port up" from "do discovery". ATM, one would call
        // this function just to get the "do discovery" functionality.
        subject = subjectList.get(0);
        logger.info("Port UP on existing node {};  clear failures and ISLFound", subject);
        subject.setFoundIsl(false);

        subject.clearConsecutiveFailure();
