Assignment of an Ethertype for IPv6 with Low-Power Wireless Personal Area Network (LoWPAN) Encapsulation
使用低功耗无线个人区域网（LoWPAN）封装为IPv6分配以太网类型
Abstract
摘要
When carried over Layer 2 technologies such as Ethernet, IPv6 datagrams using Low-Power Wireless Personal Area Network (LoWPAN) encapsulation as defined in RFC 4944 must be identified so the receiver can correctly interpret the encoded IPv6 datagram. The IETF officially requested the assignment of an Ethertype for that purpose and this document reports that assignment.
当通过第2层技术（如以太网）传输时，必须识别使用RFC 4944中定义的低功耗无线个人局域网（LoWPAN）封装的IPv6数据报，以便接收器能够正确解释编码的IPv6数据报。IETF正式要求为此目的分配Ethertype，本文件报告了该分配。

The IETF defined "LoWPAN encapsulation", a format for IPv6 [RFC2460] datagram encapsulation [RFC4944]. This document regards any IPv6 datagram using the Dispatch octet as defined in Section 5.1 of RFC 4944 as using LoWPAN encapsulation. LoWPAN encapsulation as defined in RFC 4944 has been updated by [RFC6282], and may be extended and modified by future IETF Standards. The intended Layer 2 technology for IPv6 datagrams using LoWPAN encapsulation as originally defined is [IEEE.802.15.4_2011], which does not provide for a protocol switch in its Layer 2 headers.
IETF定义了“低泛封装”，这是IPv6[RFC2460]数据报封装[RFC4944]的一种格式。本文件将使用RFC 4944第5.1节中定义的调度八位字节的任何IPv6数据报视为使用低泛封装。RFC 4944中定义的低泛封装已由[RFC6282]更新，并可能由未来的IETF标准扩展和修改。最初定义的使用LoWPAN封装的IPv6数据报的预期第2层技术是[IEEE.802.15.4_2011]，它在第2层报头中没有提供协议交换机。
The following list gives some example use cases for the Ethertype-based protocol dispatch for the LoWPAN-encapsulated IPv6 datagram:
下表给出了一些基于Ethertype的协议分派的示例用例，用于低泛封装IPv6数据报：
o Usage of LoWPAN encapsulation in conjunction with IEEE 802.15.9 Multiplexed Data Service [IEEE802159], which provides the ability to perform upper layer protocol dispatch for IEEE 802.15.4 networks. Wi-SUN Alliance intends to use the 15.9 Multiplexed Data Information Element for upper layer protocol dispatch. As specified in IEEE 802.15.9, dispatch of LoWPAN encapsulation frames will require that an Ethertype be assigned for LoWPAN encapsulation.
o 将低泛封装与IEEE 802.15.9多路复用数据服务[IEEE802159]结合使用，可为IEEE 802.15.4网络执行上层协议调度。Wi-SUN联盟打算使用15.9多路复用数据信息元素进行上层协议调度。按照IEEE 802.15.9的规定，低PAN封装帧的调度需要为低PAN封装分配一个Ethertype。
o LoWPAN encapsulation will likely be needed for Wi-Fi Alliance's HaLoW [HALOW] standard (low-power operation in the 900 MHz band).
o Wi-Fi联盟的HaLoW[HaLoW]标准（900 MHz频段的低功耗操作）可能需要低泛封装。
o Other Layer 2 technologies such as Ethernet and debugging tools such as Wireshark require a unique Protocol Type field for LoWPAN encapsulation to properly interpret IPv6 datagrams that use LoWPAN encapsulation.
o 其他第2层技术（如以太网）和调试工具（如Wireshark）需要一个唯一的协议类型字段用于低泛封装，以正确解释使用低泛封装的IPv6数据报。
o Any existing or future Layer 2 technology, incorporating Ethertype-based upper layer dispatch, can use the Ethertype proposed in this document to dispatch LoWPAN-encapsulated IPv6 datagrams.
o 任何现有或未来的第2层技术，包括基于Ethertype的上层调度，都可以使用本文中提出的Ethertype来调度低泛封装的IPv6数据报。
The IETF formally submitted a request to IEEE for assignment of an Ethertype for IPv6 datagrams using LoWPAN encapsulation. IEEE has responded with the assignment of Ethertype 0xA0ED for this purpose. The assignment has been recorded by IEEE [IEEE-ETHERTYPES].
IETF正式向IEEE提交了一份请求，要求使用低泛封装为IPv6数据报分配以太网类型。为此，IEEE已将Ethertype 0xA0ED指定为响应。该分配已由IEEE[IEEE-ETHERTYPES]记录。
The following entry has been added to the "ETHER TYPES" subregistry of the "IEEE 802 Numbers" registry [IANA-IEEE802]:
