_ & handle to the centralised multicast simulation object.
_ & handle for classifier that looks at the high bit of the destination address in each packet to determine whether it is a multicast packet (bit = 1) or a unicast packet (bit = 0).
_ & handle to classifier that performs the s, g, iif match.
_ & array indexed by s, g of handles that replicate a multicast packet on to the required links.
_ & array indexed by multicast group of the list of agents at the local node that listen to the specific group.
_ & Cached list of outgoing interfaces at this node.
_ & Cached list of incoming interfaces at this node.
Link and SimpleLink&
_ & handle for the NetworkInterface object placed on this link.
_ & first object on the link, a no-op connector. However, this object contains the instance variable, link
_, that points to the container Link object.
_ & Class variable--holds the next available interface number.
