Abstract:
1. A network interface included in a node of an Internet Protocol version 6 (Ipv6)-based wireless network, the network interface comprising: a media access control (MAC) driver for storing at least one multicast connection identifier (CID) and a MAC address of the node which is mapped in the multicast CID; and a control unit for receiving a multicast message which is transmitted from a base station (BS), and transferring the multicast message to an Internet Protocol (IP) layer, when the multicast message includes the multicast CID which is stored in the MAC driver, wherein the multicast CID is generated for enabling the multicast message to be multicast over at least any one of all-routers, all-nodes, or solicited-nodes, the multicast CID comprises an N bit prefix and a 16-n bit postfix, and each of the all-routers multicast CID, the all-nodes multicast CID, and the solicited-nodes multicast CID have an identical prefix.
