¿µ¹®³»¿ë¿ä¾à | A link in a Low-power Wireless Personal Area Network(LoWPAN) is characterized as lossy, low-power, low-bit-rate, short-range; with many nodes saving energy with long sleep periods. Multicast as used in IPv6 Neighbor Discovery(ND) [RFC4861] is not desirable in such a wireless low-power and lossy network. Therefore, this standard specifies the following functions.
- Optimize Neighbor Discovery with a mechanism that is minimal yet sufficient for the operation in both mesh-under and route-over configurations. - Minimize signaling by avoiding the use of multicast flooding and reducing the use of link-scope multicast messages. - Optimize the interfaces between hosts and their default routers. - Provide support for sleeping hosts. - Disseminate context information to hosts as needed by 6LoWPAN header compression [RFC6282]. - Disseminate context information and prefix information from the border to all routers in a LoWPAN. - Provide a multihop Duplicate Address Detection mechanism suitable for route-over LoWPANs. |
