Abstract: A method for forwarding data in a layer-2 network is provided. A first node receives a first data packet including a customer destination MAC address and customer data; generates a second data packet including a source virtual MAC address, a destination virtual MAC address and at least part of the first data packet. The at least part of the first data packet includes the customer destination MAC address and the customer data. The source virtual MAC address is a virtual MAC address assigned to the first node, and the destination virtual MAC address corresponds to the customer destination MAC address. The virtual MAC address assigned to the first node includes a first virtual MAC address segment with a first mask, which indicates a virtual MAC address space including virtual MAC addresses of child nodes of the first node. Then the first node forwards the second data packet.

Abstract translation: 提供了一种在二层网络中转发数据的方法。 第一节点接收包括客户目的地MAC地址和客户数据的第一数据分组; 产生包括源虚拟MAC地址，目的地虚拟MAC地址和第一数据分组的至少一部分的第二数据分组。 第一数据分组的至少部分包括客户目的地MAC地址和客户数据。 源虚拟MAC地址是分配给第一个节点的虚拟MAC地址，目标虚拟MAC地址对应于客户目标MAC地址。 分配给第一节点的虚拟MAC地址包括具有第一掩码的第一虚拟MAC地址段，其指示包括第一节点的子节点的虚拟MAC地址的虚拟MAC地址空间。 然后第一个节点转发第二个数据包。
