Detailed Description

API to create IPv6 RAW socket instances.

This abstract class defines the API for IPv6 RAW socket factory.

A RAW Socket typically is used to access specific IP layers not usually available through L4 sockets, e.g., ICMP. The implementer should take particular care to define the Ipv6RawSocketImpl Attributes, and in particular the Protocol attribute. Not setting it will result in a zero protocol at IP level (corresponding to the HopByHop IPv6 Extension header, i.e., Ipv6ExtensionHopByHopHeader) when sending data through the socket, which is probably not the intended behavior.

A correct example is (from src/applications/model/radvd.cc):

if (!m_socket)
  {
    TypeId tid = TypeId::LookupByName ("ns3::Ipv6RawSocketFactory");
    m_socket = Socket::CreateSocket (GetNode (), tid);
    NS_ASSERT (m_socket);
    m_socket->SetAttribute ("Protocol", UintegerValue(Ipv6Header::IPV6_ICMPV6));
    m_socket->SetRecvCallback (MakeCallback (&Radvd::HandleRead, this));
  }
