Embodiment 1

[0042] In the prior art, when the DRR algorithm is used to allocate packet fragments to each link in the bundled link, regardless of the traffic size of the data to be transmitted, all the links in the bundled link are assigned packet fragments, so each Links need to be in working state to transmit message fragments. Even if the total traffic is less than the bandwidth of a single link member, when data is sent, the data will be distributed to all link members according to the rules, which leads to All the links of the link are always in the maximum power consumption state, so it will cause a certain degree of waste of resources.

[0043] In order to solve the problems of the above-mentioned prior art, such as figure 1 As shown, the embodiment of the present invention provides a multi-link binding data distribution method, and the data of a single high-speed link is realized through multiple low-speed links bound together between the first communication device and the second c...

Embodiment 3

[0070] In this embodiment, two links of G.9701 FAST and VDSL of frequency division multiplexing are used to further illustrate the solution provided by the embodiment of the present invention, and the specific implementation includes:

[0071]Among them, the G.9701 FAST link provides 200Mbps bandwidth, and the VDSL2 link provides 80Mbps bandwidth. When data transmission requires a flow rate of 100Mbps (less than the bandwidth provided by G.9701 FAST), the specific implementation method can be:

[0072] Because the required traffic (100Mbps) is much smaller than the bandwidth provided by a link, you can directly select the high-speed link G.9701 FAST to carry the transmission of message data, that is, all 100Mbs traffic is transmitted on the G.9701 FAST link .

[0073] At the same time, at intervals (less than the timeout time that the receiving side can bear), a fragment is sequentially distributed on the G.9701 FAST and VDSL2 links, so that all links are not empty.

Embodiment 4

[0077] like image 3 As shown, the embodiment of the present invention provides a communication device 300, the communication device includes:

[0078] The bandwidth determining unit 301 is configured to determine the total bandwidth value provided by the multiple low-rate links and the value of the total bandwidth provided by the multiple low-rate links when sending data to the second communication device through multiple low-rate links that are bound together. The bandwidth difference between the required bandwidths of the two communication devices to send data;

[0079] A link adjustment unit 302, configured to adjust the M links to a dormant state if the bandwidth difference is greater than the sum of bandwidths provided by M links among the multiple low-speed links, where M is a positive integer;

[0080] A sending module 303, configured to send the data by using links other than the M links among the plurality of low-speed links.

[0081] Because in the solution provi...

Abstract

The present invention discloses a multi-link binding data distribution method and a device. The method comprises the steps of determining a bandwidth difference value between the total bandwidth value provided by a plurality of low-speed links and the needed bandwidth of the data sent by a first communication device to a second communication device, when the first communication device sends data to the second communication device via the plurality of low-speed links which are bound together; if the bandwidth difference value is greater than the bandwidth sum provided by the M links of the plurality of low-speed links, adjusting the M links into the dormant states, wherein M is a positive integer; utilizing the other links except the M links in the plurality of low-speed links to send the data. The method and device provided by the present invention solve the problems in the prior art that a message segment algorithm of binding links is large in power consumption, and wastes the resources.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a multi-link binding data distribution method and device. Background technique [0002] FTTS / B (Fiber to The Building, Fiber-To-The-Street, Fiber-To-The-Street) can provide VDSL2 (Second Generation Very High Speed ​​Digital Subscriber Line, second generation very high speed digital subscriber line) access capability, and can also provide G.9701 FAST (Fast Access to Subscriber Terminals, fast user terminal) access capability; , fiber to the curb) are directly connected to FTTS / B equipment; ADSL (Asymmetric Digital Subscriber Line, Asymmetric Digital Subscriber Line), VDSL2, and G.9701FAST services will also exist in a bundle of lines. Mode to reduce crosstalk and support vectoring (vectoring) function, need to use frequency division multiplexing; 0MHz ~ 2.2MHz for ADSL, 2.2MHz ~ 17MHz for VDSL2, 23MHz ~ 106MHz for G.9701 FAST; VDSL2 can Carry traffic up to 120Mbps, G.9701 ...
