Embodiment Construction

[0034] The embodiment of the present invention provides a data frame forwarding method based on line bundling, which can schedule user traffic in real time according to the status of each access line bound by the user. Wherein, user bundling refers to sending the data that the user needs to send from multiple uplinks, or receiving the data that the user needs to receive from multiple downlinks.

[0035] In the embodiment of the present invention, for the case where MAC (Media Access Control, Media Access Control) is used as the logical identifier, the ARP (Address Resolution Protocol) of the IP (Internet Protocol, Internet Protocol) edge node or L2C (Layer2Control, two-layer control protocol) agent , Address Resolution Protocol (Address Resolution Protocol) table, one IP address can correspond to multiple MACs, and the downlink direction can select the MAC according to the scheduling rules for forwarding. In the embodiment of the present invention, in the case of bundling acce...

Abstract

The invention embodiment discloses a method and a device for forwarding a data frame based on line bundle. The method for forwarding the data frame based on line bundle comprises the following steps: acquiring a first data frame transmitted by a user side or a network side; dividing the first data frame when the first data frame is greater than the maximum transmission unit MTU of any access linebundled to the user, wherein the sub data frames obtained from division are all less than or equal to the MTU; adding logical identifiers corresponding to the access line bundled to the user to the sub data frames; and transmitting a second data frame comprising the sub data frames and the logical identifiers of the sub data frames so that the data frame can be reformed after being received at anopposite end. The method and the device for forwarding the data frame based on the line bundle increase the bandwidth of the access line, prolong the transmission distance and improve the transmission reliability on the basis of ensuring the transmission quality of the access line.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a data frame forwarding method and device based on line bonding. Background technique [0002] Traditional subscriber broadband access lines often adopt xDSL (Digital Subscriber Line, digital subscriber line) mode, which is characterized by narrow line bandwidth and far distance between users and the central office. With the emergence of new services and the expansion of user business scale, users need higher bandwidth, but the bandwidth provided by traditional access methods cannot meet the needs of users. For example: a video stream requires 6M bandwidth, but the xDSL line can only provide a maximum bandwidth of 4M due to factors such as distance. Although the operator can adopt a new access technology, this method cannot protect the existing equipment investment, so it will greatly increase the operator's cost input. Some new access techn...
