摘要： The present invention relates to a network unit in a telecommunication network for forwarding a Layer 2 packet such as an Ethernet packet encapsulating a Layer 3 packet such as an Internet protocol packet in its payload. The Layer 2 packet being received at one of the interfaces of the network unit. The network unit therefore comprises: a forwarding database that comprises associations between an interface of the plurality of interfaces and at least one Layer 3 address. The forwarding database returns upon reception of a Layer 3 address which has a full match with one of said Layer 3 addresses in the forwarding database, the associated interface of the plurality of interfaces; and an extractor for extracting from a payload of the Layer 2 packet a destination Layer 3 address; and a forwarding engine for in response to this extraction, retrieving from the forwarding database and based upon this extracted destination Layer 3 address, the associated interface. Furthermore, the network unit forwards the Layer 2 packet towards the associated interface.
摘要翻译：本发明涉及电信网络中的网络单元，用于在其有效载荷中转发诸如封装诸如因特网协议分组之类的第3层分组的以太网分组的二层分组。第二层数据包在网络单元的一个接口处被接收。因此，网络单元包括：转发数据库，其包括多个接口的接口与至少一个第3层地址之间的关联。转发数据库在接收到与转发数据库中的所述第三层地址之一完全匹配的第三层地址，多个接口的关联接口之后返回; 以及提取器，用于从所述二层包的有效载荷中提取目的地层3地址; 以及用于响应于该提取的转发引擎，从转发数据库检索并基于该提取的目的地层3地址，相关联的接口。此外，网络单元将二层分组转发到相关联的接口。
