Functions

func GetDhcpLayer

func GetDhcpLayer(pkt gopacket.Packet) (*layers.DHCPv4, error)

func GetDhcpMessageType

func GetDhcpMessageType(dhcp *layers.DHCPv4) (layers.DHCPMsgType, error)

func GetDhcpPacketType

func GetDhcpPacketType(pkt gopacket.Packet) (string, error)

returns the DHCP Layer type or error if it's not a DHCP Packet

func HandleNextBbrPacket

func HandleNextBbrPacket(onuId uint32, ponPortId uint32, serialNumber string, doneChannel chan bool, pkt gopacket.Packet, client openolt.OpenoltClient) error

This method handle the BBR DHCP Packets BBR does not need to do anything but forward the packets in the correct direction

func HandleNextPacket

func HandleNextPacket(onuId uint32, ponPortId uint32, serviceName string, serialNumber string, portNo uint32,
	tag int, gemPortId uint32, uniId uint32, onuHwAddress net.HardwareAddr, onuStateMachine *fsm.FSM,
	pkt gopacket.Packet, pbit uint8, stream bbsim.Stream) error

func SendDHCPDiscovery

func SendDHCPDiscovery(ponPortId uint32, onuId uint32, serviceName string, tag int, gemPortId uint32,
	serialNumber string, portNo uint32, uniId uint32, stateMachine *fsm.FSM, onuHwAddress net.HardwareAddr,
	pbit uint8, stream bbsim.Stream) error

Types

type DHCPServer

type DHCPServer struct {
	DHCPServerMacAddress net.HardwareAddr
}

func NewDHCPServer

func NewDHCPServer() *DHCPServer

func (DHCPServer) HandleServerPacket

func (s DHCPServer) HandleServerPacket(pkt gopacket.Packet) (gopacket.Packet, error)

HandleServerPacket is a very simple implementation of a DHCP server that only replies to DHCPDiscover and DHCPRequest packets

type DHCPServerIf

type DHCPServerIf interface {
	HandleServerPacket(pkt gopacket.Packet) (gopacket.Packet, error)
}
