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: A bandwidth scheduling method. The method includes a bandwidth allocation apparatus receives a bandwidth request message sent by a message conversion apparatus, where the bandwidth request message includes a bandwidth requirement, and the bandwidth requirement is a bandwidth required by a user-side apparatus for completing transmission of a service. The bandwidth allocation apparatus calculates first bandwidth grant information and second bandwidth grant information based on the bandwidth requirement, where the first bandwidth grant information is information about a bandwidth that is allocated to the user-side device, and the second bandwidth grant information is information about a bandwidth that is allocated to a second access device. The bandwidth allocation apparatus sends the first bandwidth grant information to the user-side device, and the bandwidth allocation apparatus sends the second bandwidth grant information to the second access device by using a first access device.

Abstract: A message transmission method, an access node, an access controller, and an access system, where in the method, a message is processed by an access controller instead of an access node such that the access node does not need to support a relay function, reducing operation and maintenance difficulties and costs. In the method, the access controller receives a first message from the access node, and the first message includes a first identifier. The access controller obtains a line identifier according to the first identifier. The access controller obtains a second message according to the line identifier, and the second message includes the line identifier. The access controller sends the second message to a relay server.
