Metro Ethernet Network With Scaled Broadcast And Service Instance Domains

摘要：

A method of operation for a provider edge device of a core network includes receiving a customer frame from an access network; the customer frame having a first Virtual Local Area Network (VLAN) tag of a first predetermined bit length. The first VLAN tag including a service instance identifier. The service instance identifier of the first VLAN tag is then mapped into a second VLAN tag of a second predetermined bit length greater than the first predetermined bit length. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

摘要（中）：

核心网络的提供商边缘设备的操作方法包括从接入网络接收客户帧; 所述客户帧具有第一预定位长度的第一虚拟局域网（VLAN）标签。第一个VLAN标签包含服务实例标识符。然后将第一VLAN标签的服务实例标识符映射到大于第一预定位长度的第二预定位长度的第二VLAN标签。要强调的是，该摘要被提供以符合要求抽象的规则，允许搜索者或其他读者快速确定技术公开内容的主题。提交它的理解是，它不会用于解释或限制权利要求的范围或含义。 37 CFR 1.72（b）。
