Example 4 with SegmentRoutingAppConfig

use of org.onosproject.segmentrouting.config.SegmentRoutingAppConfig in project trellis-control by opennetworkinglab.

the class ArpHandler method processPacketIn.

/**
 * Processes incoming ARP packets.
 *
 * If it is an ARP request to router itself or known hosts,
 * then it sends ARP response.
 * If it is an ARP request to unknown hosts in its own subnet,
 * then it flood the ARP request to the ports.
 * If it is an ARP response, then set a flow rule for the host
 * and forward any IP packets to the host in the packet buffer to the host.
 * <p>
 * Note: We handles all ARP packet in, even for those ARP packets between
 * hosts in the same subnet.
 * For an ARP packet with broadcast destination MAC,
 * some switches pipelines will send it to the controller due to table miss,
 * other switches will flood the packets directly in the data plane without
 * packet in.
 * We can deal with both cases.
 *
 * @param pkt incoming ARP packet and context information
 * @param hostService the host service
