public class InterfaceInfo

extends DrclObj

implements InetConstants

Defines the information of an interface of a network node. The information includes the network address (NetAddress) of the node seen from that interface, the network addresses of the neighbor nodes that can be reached from that interface, the maximum transmission unit (MTU), the bandwidth, and the interface type. The interface type is not defined in INET, and should be interpreted by the upper layer protocols. Since this information is shared by multiple protocols, they must have consensus of its definition.

This class provides a set of methods to augment (addPeerNetAddress(drcl.inet.data.NetAddress, double)) and remove (removePeerNetAddress(drcl.inet.data.NetAddress)) a neighbor. It also provides methods to retrieve the local network address and the neighbor network addresses, and to query if a network address is one of the neighbors that can be reached from that interface.

The information of all the interfaces is stored and maintained at the core service layer in the Inet architecture, in which the protocols make use of the IFQuery contract to access the information from the core service layer.
