Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] figure 2 A flow chart of using token buckets for bandwidth control in a distributed system using a switching network provided for an embodiment of the present invention, as shown in figure 2 As shown, the specific steps are as follows:

[0054] Step 201: Each service board in the distributed system sets a token bucket for each other service board.

[0055] For example: if the distributed system contains n (n≥2) service boards, then (n-1) token buckets should be set for each service board.

[0056] Step 202: Each service board in the distributed system allocates the bandwidth of its own outgoing interface to other service boards in real time according to the traffic sent by other service boards.

[0057] Step 203: The service board converts the bandwidth allocated to other service boards into token generation rates, and sends...

Abstract

The invention discloses a bandwidth control method in a distributed system and an operation board. The method comprises: each operation board in the distributed system arranges a token barrel for each operation board; each operation board respectively processes the statistic for the streaming quantity sent by the other operation boards and distributes the interface bandwidth of the operation board to the other operation boards and respectively transfers the bandwidth with the other operation boards into the token generating speed rate; the generating speed rates are respectively transmitted to the tokens in the token barrel. The invention achieves the dynamic bandwidth control in the distributed system by using the exchanging net.

Description

technical field [0001] The invention relates to the technical field of bandwidth control, in particular to a bandwidth control method and a service board in a distributed system. Background technique [0002] The token bucket algorithm is the most commonly used algorithm in network traffic shaping and rate limiting. Each token in the token bucket represents a certain unit such as: bits or bytes of data. Check the number of tokens in the token bucket before forwarding the message. If there are enough tokens in the bucket, the message is allowed to be sent , otherwise the packet is not allowed to be sent. The components of this control mechanism include: the amount of data represented by a unit token, the token generation cycle, the number of tokens generated per cycle, and the token bucket capacity. [0003] figure 1 It is the flow chart of the existing flow control using the token bucket algorithm, such as figure 1 As shown, the specific steps are as follows: [0004] S...
