◆ GetMulticast()

Mac16Address ns3::Mac16Address::GetMulticast ( Ipv6Address address)
static

Returns the multicast address associated with an IPv6 address according to RFC 4944 Section 9.

An IPv6 packet with a multicast destination address (DST), consisting of the sixteen octets DST[1] through DST[16], is transmitted to the following 802.15.4 16-bit multicast address:

  0                   1
  0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5
 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
 |1 0 0|DST[15]* |   DST[16]     |
 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Here, DST[15]* refers to the last 5 bits in octet DST[15], that is, bits 3-7 within DST[15]. The initial 3-bit pattern of "100" follows the 16-bit address format for multicast addresses (Section 12).

Parameters
addressbase IPv6 address
Returns
the multicast 16-bit address.
