Member Function Documentation

virtual L3Address inet::IARP::getL3AddressFor ( const MACAddress & ) const

pure virtual

Returns the Layer 3 address for the given MAC address.

If it is not available (not in the cache, pending resolution, or already expired), UNSPECIFIED_ADDRESS is returned.

Implemented in inet::ARP, inet::GlobalARP, and inet::GenericARP.

virtual MACAddress inet::IARP::resolveL3Address	(	const L3Address &	address,
		const InterfaceEntry *	ie
	)

pure virtual

Tries to resolve the given network address to a MAC address.

If the MAC address is not yet resolved it returns an unspecified address and starts an address resolution procedure. A signal is emitted when the address resolution procedure terminates.

Implemented in inet::ARP, inet::GlobalARP, and inet::GenericARP.
