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.
The embodiment of the invention discloses a dynamic current limiting method for data transmission, which comprises the following steps of:
s11: a first rated bandwidth of a first rate limiter limiting speed for a first type of data stream is set using a rated processing bandwidth of a data receiving device.
Specifically, the first type of data stream may be used as main data to be received by the data receiving device, the priority of the first type of data stream is higher than that of the second type of data stream, in order to ensure that the first type of data stream can be transmitted to the data receiving device as fast as possible, the first rated bandwidth of the first speed limiter that limits the transmission rate for the first type of data stream is set to the maximum value as far as possible, and the first rated bandwidth of the first speed limiter may be set to be equal to the rated processing bandwidth of the data receiving device according to the rated processing bandwidth of the data receiving device, so that the first rated bandwidth of the first speed limiter reaches the maximum value, and the first type of data stream can be ensured to rapidly and effectively enter the data receiving device.
The data receiving device may be a server, a client, a network switch, or other communication device, the first type of data stream may be a data stream of a core service, and the second type of data stream may be a data stream of a non-core service, and of course, the first type of data stream and the second type of data stream may also correspond to a multi-level and a level data stream, and are not limited to two types of data streams, which both satisfy the spirit of the embodiments of the present invention.
S12: and setting the maximum forwarding bandwidth of the first speed limiter by using the maximum processing bandwidth of the data receiving equipment.
Specifically, in order to cope with the situation that the bursty data flow is instantaneously overloaded, the first speed limiter further has a maximum forwarding bandwidth on the basis of the first rated bandwidth, when the first type of data flow exceeds the first rated bandwidth of the first speed limiter in a unit time, and in order to ensure that the first type of data flow can still reach the data receiving device through the first speed limiter in such a situation, the maximum forwarding bandwidth of the first speed limiter may be set to be equal to the maximum processing bandwidth of the data receiving device, the maximum processing bandwidth of the data receiving device is greater than the rated processing bandwidth of the data receiving device, and the data receiving device and the first speed limiter can cope with the situation that the first type of data flow exceeds the first rated bandwidth in a certain time, for example, the first type of data flow exceeding the first rated bandwidth and being less than or equal to the maximum processing bandwidth can be borne within one second.
S13: and utilizing the surplus bandwidth of the difference value between the rated processing bandwidth and the current use bandwidth of the first speed limiter as a second rated bandwidth of a second speed limiter for limiting the speed of the second type of data stream, so that the second rated bandwidth of the second speed limiter is changed along with the current use bandwidth of the first speed limiter.
Specifically, the total amount of the processing bandwidth of the data receiving device is constant, in order to ensure that the data receiving device can timely and effectively receive the first type of data streams, the second rated bandwidth of the second speed limiter which limits the speed of the second type of data streams is set as a surplus bandwidth which is a difference value between a rated processing bandwidth of the data receiving device and a currently used bandwidth of the first speed limiter, and the second rated bandwidth of the second speed limiter is used as a dynamic value to follow a change of the currently used bandwidth of the first speed limiter to realize dynamic adjustment, when the data size of the first type of data streams is large and occupies a large amount of bandwidth, the second rated bandwidth will be reduced therewith, and when the data size of the first type of data streams is small and occupies a small amount of bandwidth, the second rated bandwidth will be increased therewith, for example, the rated processing bandwidth of the data receiving device is M, the currently used bandwidth of the first speed limiter is P, and the second rated bandwidth is V2, where V2 is V2= M-P.
Specifically, the second rated bandwidth changes along with the current used bandwidth of the first speed limiter, so that the bandwidth of the whole data receiving device is ensured to be capable of reaching the maximum value without being influenced by the second type of data stream on the basis of the first type of data stream during data transmission, the transmission bandwidth of the second type of data stream is influenced by the current used bandwidth of the first type of data stream, the bandwidth of the data receiving device is ensured to be preferentially served for the first type of data stream, meanwhile, when the current used bandwidth of the first speed limiter is small, the residual bandwidth of the data receiving device is provided for the second speed limiter, the second rated bandwidth of the second speed limiter is increased, the whole rated processing bandwidth of the data receiving device is ensured to be effectively used, and the situation of bandwidth waste is reduced.
It can be seen that, in the embodiments of the present invention, a first rated bandwidth is set for a first speed limiter that limits speed for a first type of data stream by using a rated processing bandwidth of a data receiving device, a maximum forwarding bandwidth of the first speed limiter is set by using a maximum processing bandwidth of the data receiving device, it is ensured that an upper limit of a bandwidth of the first speed limiter is consistent with the data receiving device, it is ensured that the first type of data stream can share the most bandwidth resources, meanwhile, the maximum forwarding bandwidth is set, so that the first speed limiter has a capability of bearing instantaneous overload of the first type of data stream, and a second rated bandwidth of a second speed limiter that limits speed for a second type of data stream is a difference between the rated processing bandwidth of the data receiving device and a current used bandwidth of the first speed limiter, so that the bandwidth that the second speed limiter can be changed with the use of the first type of data stream, thereby implementing dynamic current limiting on the second type of data stream, and ensuring preferential transmission of the first type of data stream.
The embodiment of the invention discloses a specific dynamic current limiting method for data transmission, and compared with the previous embodiment, the technical scheme is further explained and optimized in the embodiment. Referring to fig. 2, specifically:
s21: and setting the token placing rate of the token bucket speed limiter for limiting the speed of the first class of data flow by utilizing the rated processing bandwidth of the data receiving equipment and the data volume corresponding to each token.
Specifically, first overspeed governor can be token bucket overspeed governor, and when first overspeed governor was token bucket overspeed governor, the first rated bandwidth of first overspeed governor was divided by the data volume that can forward that each token of token bucket overspeed governor corresponds, obtains the token of token bucket overspeed governor and places the rate.
The forwarding data amount corresponding to each token is preset and can be set according to actual application requirements.
S22: and setting the token capacity of the token bucket speed limiter by using the maximum processing bandwidth of the data receiving equipment and the data amount corresponding to each token.
Specifically, because a certain number of tokens can be stored in advance in the token bucket speed limiter, even if the first-class data stream is instantaneously overloaded, and the tokens required by the data volume in unit time are greater than the token placement rate of the token bucket speed limiter, the remaining tokens in the token bucket can distribute tokens for the excessive data to realize overload transmission, and the upper limit of the overload transmission is the maximum processing bandwidth of the data receiving equipment, so that the token capacity of the token bucket speed limiter is set as the quotient of dividing the maximum processing bandwidth by the data volume corresponding to each token, and the transient overload phenomenon that the token bucket speed limiter can bear the data stream is ensured.
S23: and setting the token generation rate of the token speed limiter aiming at the second class data flow speed limit by utilizing the difference surplus bandwidth between the rated processing bandwidth and the current used bandwidth of the token bucket speed limiter and the data amount corresponding to each token.
Specifically, in order to save computational resources, the second speed limiter of the second type of data stream does not select a token bucket speed limiter, but adopts a token speed limiter, and does not have the capability of coping with instantaneous overload of the data stream, so that the token generation rate of the token speed limiter is equivalent to the quotient of a second rated bandwidth of the second speed limiter divided by the data amount corresponding to each token, and once the number of tokens required by the data amount of the second type of data stream exceeds the token generation rate, data congestion is generated; the automatic dynamic current limitation of the second class data stream is realized by dynamically adjusting the token generation rate of the token speed limiter, and the first class data stream is ensured to have enough bandwidth for use.
Further, a second speed limiter can be set as a token bucket speed limiter according to actual application requirements, and at the moment, the capacity of the token bucket can be set according to the actual application requirements.
