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

Example 31 with Ethernet

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

the class PipelineInterpreterImpl method mapInboundPacket.

@Override
public InboundPacket mapInboundPacket(PiPacketOperation packetIn, DeviceId deviceId) throws PiInterpreterException {
    // We assume that the packet is ethernet, which is fine since mytunnel.p4
    // can deparse only ethernet packets.
    Ethernet ethPkt;
    try {
        ethPkt = Ethernet.deserializer().deserialize(packetIn.data().asArray(), 0, packetIn.data().size());
    } catch (DeserializationException dex) {
        throw new PiInterpreterException(dex.getMessage());
    }
    // Returns the ingress port packet metadata.
    Optional<PiPacketMetadata> packetMetadata = packetIn.metadatas().stream().filter(metadata -> metadata.id().toString().equals(INGRESS_PORT)).findFirst();
    if (packetMetadata.isPresent()) {
        short s = packetMetadata.get().value().asReadOnlyBuffer().getShort();
        ConnectPoint receivedFrom = new ConnectPoint(deviceId, PortNumber.portNumber(s));
        return new DefaultInboundPacket(receivedFrom, ethPkt, packetIn.data().asReadOnlyBuffer());
    } else {
        throw new PiInterpreterException(format("Missing metadata '%s' in packet-in received from '%s': %s", INGRESS_PORT, deviceId, packetIn));
    }
}
