Abstract: Aspects of geotagged communications are described herein. In one embodiment, a data unit including a geotag field is received over an ingress port of a network component. In turn, the network component may determine a path for forwarding the data unit to a location associated with the geotag field and with reference to a forwarding decision index. The path may include a least distance hop or a least distance route for forwarding or routing the data unit. With reference to the forwarding path, the network component may identify an egress port for forwarding the data unit. The network component may also forward the data unit over the egress port. According to other aspects, geolocation data may enable a network component to implement geotag-based virtual local area networks, geotag-based multiprotocol label switching, geotag-based fault detection and isolation, or geotag-based firewalls and fencing in wired routers or switches, for example.

Abstract translation: 本文描述了地理标记通信的方面。 在一个实施例中，包括地理标记字段的数据单元在网络组件的入口端口上被接收。 反过来，网络组件可以确定用于将数据单元转发到与地理标记字段相关联的位置并参照转发决策索引的路径。 路径可以包括用于转发或路由数据单元的最小距离跳或最小距离路由。 参考转发路径，网络组件可以识别用于转发数据单元的出口端口。 网络组件还可以通过出口端口转发数据单元。 根据其他方面，地理位置数据可以使得网络组件能够在有线路由器或交换机中实现基于地理标号的虚拟局域网，基于地理标识的多协议标签交换，基于地理标识的故障检测和隔离，或基于地理标识的防火墙和防护， 例如。
