uint8_t ns3::Ipv6ExtensionFragment::GetExtensionNumber

(

)

const [virtual]

Get the extension number.

Returns:

extension number

Implements ns3::Ipv6Extension.

void ns3::Ipv6ExtensionFragment::GetFragments	(	Ptr< Packet >	packet,
		uint32_t	fragmentSize,
		std::list< Ptr< Packet > > &	listFragments
	)

Fragment a packet.

Parameters:

packet	the packet

		uint8_t	offset,
		Ipv6Header const &	ipv6Header,
		Ipv6Address	dst,
		uint8_t *	nextHeader,

Process method Called from Ipv6L3Protocol::Receive.

Parameters:

packet	the packet
offset	the offset of the extension to process
ipv6Header	the IPv6 header of packet received
dst	destination address of the packet received (i.e. us)
nextHeader	the next header
isDropped	if the packet must be dropped

Returns:

the size processed
