Message ARPPacket

File: Network/ARP/ARPPacket.msg

ARP packet. This is a specialized version: prepared for IEEE 802 hardware addresses and IPv4. Packet fields are therefore represented by C++ classes MACAddress and IPAddress. Also, some ARP protocol header fields are not modelled explicitly (their values are implied):

hardwareType (not needed for modelling);
protocol type (0x800 IPv4)
hardware address length (6)
protocol address length (4)

Fields:

Name	Type	Description
opcode	int
srcMACAddress	MACAddress
destMACAddress	MACAddress
srcIPAddress	IPAddress
destIPAddress	IPAddress
