virtual int send(const Iface &iface, uint16_t sockfd, const Pkt4Ptr &pkt)
Send packet over specified socket.
virtual SocketInfo openSocket(Iface &iface, const isc::asiolink::IOAddress &addr, const uint16_t port, const bool receive_bcast, const bool send_bcast)
Open primary and fallback socket.
virtual Pkt4Ptr receive(Iface &iface, const SocketInfo &socket_info)
Receive packet over specified socket.
Abstract packet handling class.
