Examples with IP org.onlab.packet.IP used on opensource projects

Example 1 with IP

use of org.onlab.packet.IP in project onos by opennetworkinglab.

the class DirectHostManager method handle.

private boolean handle(Ethernet eth) {
    checkNotNull(eth);
    // skip them.
    if (!enabled || (eth.getEtherType() != Ethernet.TYPE_IPV6 && eth.getEtherType() != Ethernet.TYPE_IPV4)) {
        return false;
    }

    IpAddress dstIp;

        dstIp = IpAddress.valueOf(ip.getDestinationAddress());
    } else {
        IPv6 ip = (IPv6) eth.getPayload();
        dstIp = IpAddress.valueOf(INET6, ip.getDestinationAddress());
    }
    // Looking for a candidate output port.
    Interface egressInterface = interfaceService.getMatchingInterface(dstIp);
    if (egressInterface == null) {

        return false;
    }
    // Looking for the destination mac.
    Optional<Host> host = hostService.getHostsByIp(dstIp).stream().filter(h -> h.location().equals(egressInterface.connectPoint())).filter(h -> h.vlan().equals(egressInterface.vlan())).findAny();
    // and we queue the packets waiting for a destination.
    if (host.isPresent()) {
        transformAndSend((IP) eth.getPayload(), eth.getEtherType(), egressInterface, host.get().mac());
    } else {
        hostService.startMonitoringIp(dstIp);
        ipPacketCache.asMap().compute(dstIp, (ip, queue) -> {
            if (queue == null) {
                queue = new ConcurrentLinkedQueue<>();
            }
            queue.add((IP) eth.getPayload());
            return queue;
        });
    }
    return true;
