◆ DoDispose()

void ns3::Ipv4L3ClickProtocol::DoDispose ( void  )
overrideprotectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::Object.

addressThe IP address being searched for
Returns
The interface number of the Ipv4 interface with the given address or -1 if not found.

bool ns3::Ipv4L3ClickProtocol::IsDestinationAddress ( Ipv4Address  address,

Determine whether address and interface corresponding to received packet can be accepted for local delivery.

Parameters
addressThe IP address being considered
iifThe incoming Ipv4 interface index
Returns
true if the address is associated with the interface index

This method can be used to determine whether a received packet has an acceptable address for local delivery on the host. The address may be a unicast, multicast, or broadcast address. This method will return true if address is an exact match of a unicast address on one of the host's interfaces (see below), if address corresponds to a multicast group that the host has joined (and the incoming device is acceptable), or if address corresponds to a broadcast address.

If the Ipv4 attribute StrongEndSystemModel is true, the address must match one assigned to the incoming device. If the attribute is false, the unicast address may match any of the Ipv4 addresses on any interface.

Ipv4Address ns3::Ipv4L3ClickProtocol::SelectSourceAddress ( Ptr< const NetDevice device,

Ipv4InterfaceAddress::InterfaceAddressScope_e  scope 
)
overridevirtual

Return the first primary source address with scope less than or equal to the requested scope, to use in sending a packet to destination dst out of the specified device.

This method mirrors the behavior of Linux inet_select_addr() and is provided because interfaces may have multiple IP addresses configured on them with different scopes, and with a primary and secondary status. Secondary addresses are never returned.

See also
Ipv4InterfaceAddress

If a non-zero device pointer is provided, the method first tries to return a primary address that is configured on that device, and whose subnet matches that of dst and whose scope is less than or equal to the requested scope. If a primary address does not match the subnet of dst but otherwise matches the scope, it is returned. If no such address on the device is found, the other devices are searched in order of their interface index, but not considering dst as a factor in the search. Because a loopback interface is typically the first one configured on a node, it will be the first alternate device to be tried. Addresses scoped at LINK scope are not returned in this phase.

If no device pointer is provided, the same logic as above applies, only that there is no preferred device that is consulted first. This means that if the device pointer is null, input parameter dst will be ignored.

If there are no possible addresses to return, a warning log message is issued and the all-zeroes address is returned.

Parameters
deviceoutput NetDevice (optionally provided, only to constrain the search)
dstDestination address to match, if device is provided
scopeScope of returned address must be less than or equal to this
Returns
the first primary Ipv4Address that meets the search criteria
