Detailed Description

Ipv6QueueDiscItem is a subclass of QueueDiscItem which stores IPv6 packets.

Header and payload are kept separate to allow the queue disc to manipulate the header, which is added to the packet when the packet is dequeued.

Definition at line 39 of file ipv6-queue-disc-item.h.

ns3::Ipv6QueueDiscItem::Ipv6QueueDiscItem	(	Ptr< Packet >	p,
		const Address &	addr,
		uint16_t	protocol,

	)

Create an IPv6 queue disc item containing an IPv6 packet.

Parameters

p	the packet included in the created item.
addr	the destination MAC address
protocol	the protocol number
header	the IPv6 header

bool ns3::Ipv6QueueDiscItem::GetUint8Value	(	QueueItem::Uint8Values	field,
		uint8_t &	value
	)		const

virtual

Retrieve the value of a given field from the packet, if present.

Parameters

field	the field whose value has to be retrieved
value	the output parameter to store the retrieved value

Returns: true if the requested field is present in the packet, false otherwise.
