aaa AAA.java
└Ethernet buildEapolResponse(MacAddress dstMac, MacAddress srcMac,
short vlan, byte eapolType, EAP eap)

- request packet in via packetservice

└void process(PacketContext context)
- extract the original ethernet frame from the packet information,
identify if incoming packet comes from supplicant(EAP) or RADIUS

- creates and initializes fields of a RADIUS packet
└void handleSupplicantPacket(InboundPacket inPakcet)
