ETSI EN 302 636-6-1规定了通过中定义的ETSI地理网络协议传输IPv6数据包 ETSI EN 302 636-4-1[7]通过一个称为GN6ASL（IPv6地理网络）的协议适配子层 适应子层）。本文件的范围仅限于GN6ASL。本文件中规定的技术满足地理网络和IPv6集成的要求 如ETSI EN 302 636-1[3]所述。特别是，这些技术允许ETSI传输IPv6数据包 ETSI EN 302 636-4-1[7]中给出的地理网络协议，支持IPv6数据包的子IP多跳传输，例如:。 g、 在 车辆网络。因此，IPv6基础设施网络的连接点提供的连接性 通过移动中继节点扩展。除此之外，本文件中描述的技术允许 用于IPv6多播数据包的地理广播。

ETSI EN 302 636-6-1 specifies the transmission of IPv6 packets over the ETSI GeoNetworking protocol as defined in ETSI EN 302 636-4-1 [7] via a protocol adaptation sub-layer referred to as the GN6ASL (GeoNetworking to IPv6 Adaptation Sub-Layer). The scope of the present document is limited to the GN6ASL.The techniques specified in the present document fulfil the requirements for GeoNetworking and IPv6 integration described in ETSI EN 302 636-1 [3]. In particular, these techniques allow for the transport of IPv6 packets by ETSI GeoNetworking protocol given in ETSI EN 302 636-4-1 [7], enabling sub-IP multi-hop delivery of IPv6 packets, e.g. in a vehicular network. As a result, the connectivity provided by points-of-attachment to IPv6 infrastructure networks is extended by means of mobile relay nodes. In addition to that, the techniques described in the present document allow for geocasting of IPv6 multicast packets.
