Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a method for balancing load of multi-channel transmission according to an embodiment of the present invention includes:
and 11, determining all sequence elements according to the number of the member channels, wherein the member channel arrangement information contained in each sequence element is unique.
In order to arbitrate among multiple channels, the vertical axis of the sequence element (seed) and the number of member channels should be consistent; meanwhile, in order to ensure that each channel is selected once in seed, the horizontal axis of seed should also be consistent with the number of member channels, so if the number of member channels is N, then seed is an N × N matrix.
Assuming that there are n member channels, since the way all the member channels are arranged in each seed is summarized as:
i.e., the number of member channels factorizes several ways.
Once the seed number is determined, all the seeds can be calculated by nested loops.
For this reason, assuming that the number of member channels is n, step 11 may first construct an n × n two-dimensional matrix, and then determine all sequence elements, i.e., the sequence elements of the number of member channels factorial number, according to different arrangement manners of all member channels in the two-dimensional matrix, where each sequence element is an n × n two-dimensional matrix in which only one unit in each row and each column is true, and the remaining units are false.
For example, for a transmission comprising 3 member channels, 3 × 2 × 1 ═ 6 sequence elements can be determined, see fig. 2-a and 2-b, fig. 2-a being a three-channel system model with all its seeds as shown in fig. 2-b. For a transmission comprising 4 member channels, it is possible to determine 24 sequence elements, see fig. 3-a and 3-b, for example, with 4 × 3 × 2 × 1, fig. 3-a being a four-channel system model, the seed of the corresponding part of which is shown in fig. 3-b. Wherein the vertical axis squares of each seed represent different channels, the horizontal axis squares of each seed represent time order, and the shaded squares represent selected channels.
And 12, selecting all or part of sequence elements from all the sequence elements to form an arbitration template.
The arbitration template is composed of a plurality of seeds, for example, for a seed determined by the number N of member channels, M (1 ≦ M ≦ N) are selected from all the seeds, and the formed arbitration template is a (M × N) × N two-dimensional matrix. The selection of the number M is mainly based on the implementation of hardware, and generally, the more the selected seed number is, the higher the requirement on hardware is.
The selected seeds form an arbitration template, all or part of the seeds can be selected from all the seeds by adopting a random factor mode, and the arbitration template is formed by arranging according to the selection time sequence; or, all or part of seeds are selected from all seeds by using a mode of configuring an array, and the arbitration template is determined to be constructed by using the number and the sequence.
For example, if a random factor is used to select a seed for 4 × 3 × 2 × 1 ═ 24 seeds determined by 4 member channels, the number of selected seeds is {24 × 0.3} - } 7 when the random factor is 0.3, where { } represents a value, and then these selected seeds are arranged in the selection time order to construct the arbitration template.
Referring to fig. 4, fig. 4 is an example of constructing an arbitration template by selecting partial seeds, randomly selecting a certain number of seeds from all seeds, and then arranging the selected seeds together in a selection time sequence to obtain the arbitration template.
And 13, traversing the arbitration template to determine the sending sequence of each channel.
As described above, the arbitration template is constructed as a two-dimensional matrix of (M × N) × N, in which the horizontal axis is the time axis, and the transmission order is determined; the vertical axis is a spatial axis, and a transmission channel is determined, so that the transmission sequence of each channel can be determined by traversing the two-dimensional matrix of the arbitration template.
Taking the arbitration template constructed in fig. 4 as an example, referring to fig. 5, traversing the arbitration template from right to left to obtain the sending sequence of each channel is:
0，3，2，1，3，2，0，1，0，3，1，2，1，0，3，2。
therefore, the sending sequence is randomly changed, the rule of the existing polling traversal channel sending sequence is broken through, messages are randomly distributed to all the channels, and therefore the actual load balance of all the channels can be guaranteed.
Therefore, in the multi-channel transmission load balancing method provided by the embodiment of the present invention, first, all sequence elements are determined by the number of member channels, then, a certain number of sequence elements are randomly selected from all the sequence elements to construct an arbitration template, and finally, the arbitration template is traversed to determine a sending sequence of each channel, so that a message is randomly distributed to each channel, the actual load balancing of each channel is ensured, the problem of uneven load distribution in the prior art when the message length rule in the traffic changes is solved, and the purpose of uniformly distributing the message to each channel when the message length rule in the traffic changes is achieved; moreover, under the condition that the message length in the flow is randomly changed, the equal distribution probability of each channel is also ensured, and the performance can be kept consistent with the prior art.
Based on the method provided by the embodiment of the present invention, referring to fig. 6, the embodiment of the present invention provides a multi-channel transmission load balancing apparatus, including:
a sequence element determination unit 61, configured to determine all sequence elements according to the number of member channels, where the member channel arrangement information included in each sequence element is unique;
an arbitration template building unit 62, configured to randomly select a certain number of sequence elements from all the sequence elements to build an arbitration template;
and a sending sequence determining unit 63, configured to traverse the arbitration template to determine a sending sequence of each channel.

The arbitration template building unit 62 is configured to randomly select a certain number of sequence elements from all the sequence elements in a random factor manner, and arrange and build an arbitration template according to a selection time sequence; or randomly selecting a certain number of sequence elements from all the sequence elements by using a configuration array mode, and determining to use the serial number and the sequence to construct an arbitration template; wherein the constructed arbitration template is a two-dimensional matrix composed of the randomly selected sequence elements.
The transmission sequence determining unit 63 is configured to traverse the two-dimensional matrix of the arbitration template, a horizontal axis of the two-dimensional matrix determines a transmission sequence, and a vertical axis of the two-dimensional matrix determines a transmission channel.
It can be understood that the multi-channel transmission load balancing device provided by the embodiment of the present invention can be implemented by hardware logic or software, and performs balanced distribution on messages with regularly changing lengths in the traffic to each channel; for the message with the length changing randomly in the flow, the equal distribution probability of each channel can still be ensured, and the performance is consistent with that of the prior art.
Finally, it should be noted that the multi-channel transmission load balancing method and apparatus provided in the embodiments of the present invention may be applied to any scenario in which packets need to be equally divided to multiple ports according to the number.
