Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

For network traffic, factors affecting quality of service (QoS) include bandwidth of transmission, delay of transmission, packet loss rate of data, and the like. In the network, the service quality can be improved by measures of ensuring the transmission bandwidth, reducing the transmission time delay, reducing the packet loss rate of data, reducing the time delay jitter and the like.

Since network resources are limited, the quality of service of a certain type of service may be compromised while the quality of service of other services is guaranteed. Therefore, a network manager needs to reasonably plan and allocate network resources according to the characteristics of various services, so that the network resources are efficiently utilized.

In order to make the limited network resources to be more effective and to better serve more users, the traffic of the users needs to be limited. Traffic policing, traffic shaping, and rate limiting may implement a rate limiting function for traffic that requires measurement of traffic through the network device. The traffic is typically measured using Token buckets (Token buckets).

A token bucket may be considered a container that holds a certain number of tokens. The software system places tokens into the bucket at a set speed, and when the tokens in the bucket are full, the excess tokens overflow and the tokens in the bucket are not increased any more.

When the token bucket is used for evaluating the traffic specification, the number of tokens in the token bucket is determined according to whether the number of tokens in the token bucket is enough to satisfy the forwarding of the data message. If enough tokens exist in the bucket and the forwarding of the data message is satisfied, the flow of the data message is considered to be in compliance or in compliance with the specification, otherwise, the flow is considered to be in compliance or out of compliance.

Flow supervision refers to controlling flow, and by supervising the flow rate entering the network, the excess flow is punished, so that the entering flow is limited within a reasonable range, and the network resources and the benefits of operators are protected. For example, HTTP messages may be limited from occupying more than 50% of the network bandwidth. If it is determined that the traffic is out of specification, the traffic policing may choose to discard out-of-specification messages, or to reconfigure the priority of the out-of-specification messages.

At present, as shown in fig. 1, fig. 1 is a schematic diagram of forwarding a service packet by a member port in an existing aggregation port. In fig. 1, the aggregation port includes two member ports, the two member ports are respectively in two interface boards, and each interface board is provided with a token bucket. If traffic policing is implemented on the aggregation port, it will result in actual traffic being many times the anticipated policing. The dotted line range indicates that the aggregation port is formed by aggregating cross-board member ports, and the service messages in the member port 1 and the service messages in the member port 2 respectively realize token bucket speed limitation in respective interface boards, but the service flow is 2 times of the speed-limited flow.

In order to solve the defect that the service flow exceeds the speed-limiting flow, in practical application, all service messages of each member port in the aggregation port are transmitted to an interface board to realize the speed limitation of the token bucket. As shown in fig. 2, fig. 2 is a schematic diagram of all service messages of each member port in the existing aggregation port being transmitted to an interface board. In fig. 2, a token bucket is arranged in the member port 2, the service messages in the member port 1 are all transmitted to the member port 2, and after the speed of the token bucket is limited, the service messages meeting the specification are transmitted to the member port 1 and are forwarded by the member port 1.

However, the above-mentioned manner of transmitting all the service packets of each member port to an interface board to implement token bucket speed limit also brings the following disadvantages: 1) the bandwidth of a channel used for transmitting the service message between the interface boards is smaller, and when the service flow of a member port needing transmitting is larger than the bandwidth of the channel between the interface boards, the service flow is largely discarded; 2) the mutual transparent transmission of service messages between interface boards consumes more CPU, and affects the working efficiency of CPU.

The detection method provided in the embodiments of the present application is explained in detail below. Referring to fig. 3, fig. 3 is a flowchart of a communication method according to an embodiment of the present disclosure. The method is applied to a mainboard, and the communication method provided by the embodiment of the application can comprise the following steps.

Step 310, receiving a first service packet.

Specifically, the first interface board receives a service traffic, for example, receives a first service packet.

In this embodiment of the application, the first interface board is located in the first frame, and a first token bucket is disposed in the first interface board.

The first interface board includes a first interface, which may be a selected member port of the aggregation ports. The aggregation port also includes other selected member ports, such as the second interface. The second interface is arranged in a second interface board, and the second interface board is arranged in a second frame.

It is understood that the aggregation port has a rate-limiting bandwidth (e.g., 10M), and the limit bandwidth of each member port in the aggregation port inherits the rate-limiting bandwidth of the aggregation port, i.e., the rate-limiting bandwidth of each member port is also 10M. The speed-limiting bandwidth of the interface board where each member port is located is also the speed-limiting bandwidth of each member port.

Further, the first interface receives the first service packet.

Step 320, according to the first service packet, determining whether a first number of tokens satisfying the forwarding of the first service packet exist in the first token bucket.

Specifically, according to the description of step 310, after receiving the first service packet, the first interface board determines whether a first number of tokens satisfying the forwarding of the first service packet exists in the first token bucket.

If so, go to step 330; if the token number does not exist, the number of the tokens in the first token bucket is insufficient at the moment, and the first interface board discards the first service message.

And step 330, if yes, forwarding the first service packet, and deducting the first number of tokens from the first token bucket.

Specifically, according to the description of step 320, if there are a first number of tokens satisfying the forwarding of the first service packet in the first token bucket, the first interface board forwards the first service packet, and deducts the first number of tokens from the first token bucket.

Step 340, sending a first notification message to a second interface board, where the first notification message includes a first value, and the first value indicates the first number of tokens, so that the second interface board deducts the first number of tokens from a second token bucket set in the second interface board.

Specifically, according to the description of step 340, after the first interface board deducts the first number of tokens from the first token bucket, the first interface board generates a first notification message, where the first notification message includes a first value, and the first value represents the first number of tokens.

The first interface board sends a first notification message to the second interface board. And after receiving the first notification message, the second interface board acquires a first value from the first notification message. And the second interface board deducts a first number of tokens from a second token bucket set by the second interface board.

Further, in this embodiment of the application, the second interface board is located in the second frame, and a second token bucket is disposed in the second interface board. A token bucket channel is established between the first interface board and the second interface board, and the token bucket channel is used for mutually sending the number of tokens consumed by the first interface board and the second interface board.

As shown in fig. 4, fig. 4 is a schematic diagram illustrating that the interface boards provided in the embodiment of the present application send notification messages to each other. In fig. 4, a token bucket is set in each interface board, and the token buckets have the same capacity and the same dropping rate for dropping tokens. The interface board establishes a token bucket channel for transmitting a notification message including the number of tokens currently consumed by the interface board.

In the embodiment of the application, the release rate is not greater than the speed limit bandwidth of the interface board. For example, the rate-limited bandwidths of all the interface boards are the same and 10M, and the dropping rate of the token bucket is not greater than the rate-limited bandwidth of the interface board, that is, the dropping rate is 10M at most.

Further, in this embodiment of the present application, the first interface board puts tokens into the first token bucket according to a preset putting rate.

Therefore, by applying the communication method and the communication device provided by the application, the first interface board receives the first service message; according to the first service message, the first interface board judges whether a first token bucket has a first number of tokens which meet the requirement of forwarding the first service message; if yes, the first interface board forwards the first service message, and deducts a first number of tokens from the first token bucket; the first interface board sends a first notification message to the second interface board, wherein the first notification message comprises a first value, and the first value represents a first number of tokens, so that the second interface board deducts the first number of tokens from a second token bucket arranged in the second interface board; and the second interface board is positioned in the second frame.

Therefore, the interface boards in different frames only transmit the number of tokens deducted by the interface boards, and do not transmit the service messages mutually, so that the problems that the service messages are largely discarded and the working efficiency of a CPU is influenced in the process of transmitting the service messages mutually among the interface boards are solved. The token bucket processing performance is improved, and meanwhile, the consumption of a CPU and the pressure of inter-frame communication are reduced.

Optionally, in this embodiment of the present application, a process in which the first interface board receives the second notification message sent by the second interface board is further included.

Specifically, the second interface board receives the service traffic, for example, receives the second service packet. Further, the second interface receives a second service packet.

And after receiving the second service message, the second interface board judges whether a second token bucket has a second number of tokens which meet the requirement of forwarding the second service message. If the token number does not exist, the number of the tokens in the second token bucket is insufficient at the moment, and the second service message is discarded by the second interface board.

And if a second quantity of tokens meeting the requirement of forwarding the second service message exists in the second token bucket, the second interface board forwards the second service message and deducts the second quantity of tokens from the second token bucket.

After the second interface board deducts a second number of tokens from the second token bucket, the second interface board generates a second notification message, where the second notification message includes a second value, and the second value represents the second number of tokens.

The second interface board sends a second notification message to the first interface board. And after receiving the second notification message, the first interface board acquires a second value from the second notification message.

And according to the second quantity of tokens, the first interface board deducts the second quantity of tokens from the first token bucket.

In this embodiment of the present application, when each member port (each member port selected in the aggregation group) in the aggregation port is on a different interface board, the token bucket in the interface board where one member port is located subtracts a token, and at the same time, the same token is subtracted from the token bucket in the interface board where another member port is located, so that it can be ensured that the speed-limited bandwidth of the aggregation port can be ensured regardless of whether the traffic flows pass through the interface boards where the different member ports are located.

Optionally, before step 340 of the present application, a process that the first interface board determines whether to receive the notification message sent by another interface board, and determines whether to send the first notification message according to a determination result is further included.

Specifically, the first interface board determines whether a third notification message sent by the second interface board has been received, where the third notification message includes a third value, and the third value indicates a third number of tokens.

And if the first interface board receives the third notification message and deducts a third number of tokens from the first token bucket according to the third number of tokens, the first interface board sends the first notification message to the second interface board.

And if the first interface board does not receive the third notification message, the first interface board does not send the first notification message to the second interface board.

In the embodiment of the present application, if only the traffic flow exists in the first interface board and the traffic flow does not exist in the second interface board, the token bucket in the second interface board may be caused to blindly deduct the token, and thus the way of deducting the token is meaningless. Therefore, through the foregoing determination process, if there is token consumption in the token bucket in the first interface board and the token bucket in the first interface board does not deduct the token when the service packet is forwarded by another interface board, the notification message is not sent to another interface board after the token consumption of the first interface board, so as to avoid a meaningless token deduction manner.

Optionally, before step 340 in this embodiment of the present application, a process that the first interface board determines whether to receive the notification message sent by another interface board within a preset time period, and determines whether to send the first notification message according to a determination result is further included.

Specifically, within a preset time period, the first interface board determines whether a fourth notification message sent by the second interface board has been received, where the fourth notification message includes a fourth value, and the fourth value indicates a fourth number of tokens.

In the embodiment of the application, the preset time period is based on milliseconds, and the smaller the configured time period value is, the more sensitive the service flow is. The preset time period may be set to 50ms in general.

And if a fourth notification message is received before the preset time period is ended and a fourth number of tokens are deducted from the first token bucket according to the fourth number of tokens, the first interface board sends the first notification message to the second interface board.

And if the fourth notification message is not received within the preset time period or at the end of the preset time period, the first interface board does not send the first notification message to the second interface board.

In the embodiment of the present application, an interface board may have a scene where traffic flow is discontinuous. If the traffic flow in the first interface board is intermittent and the traffic flow in the second interface board is stable, the token bucket in the first interface board can be caused to blindly deduct the token, and thus the way of deducting the token is meaningless.

Therefore, by combining the preset time period with the judgment process, if the preset time period is over, the first interface board receives the notification messages sent by other interface boards, the first interface board does not send the notification messages to other interface boards any more, and unless the subsequent other interface boards send the notification messages again, the first interface board is awakened to send the notification messages to other interface boards. The shorter the preset time period is, the more sensitive to the traffic flow, and conversely, the less sensitive to the traffic flow.

Based on the same inventive concept, the embodiment of the application also provides a communication device corresponding to the communication method. Referring to fig. 5, fig. 5 is a structural diagram of a communication device according to an embodiment of the present application. The device is applied to a first interface board, the first interface board is positioned in a first frame, a first token bucket is arranged in the first interface board, and the device comprises:

a receiving unit 510, configured to receive a first service packet;

a first determining unit 520, configured to determine, according to the first service packet, whether a first number of tokens that satisfy forwarding of the first service packet exist in the first token bucket;

a sending unit 530, configured to forward the first service packet if the first service packet is satisfied, and deduct the first number of tokens from the first token bucket;

the sending unit 530 is further configured to send a first notification message to a second interface board, where the first notification message includes a first value, and the first value indicates the first number of tokens, so that the second interface board deducts the first number of tokens from a second token bucket set in the second interface board;

wherein the second interface board is in the second frame.

Optionally, the receiving unit 510 is further configured to receive a second notification message sent by the second interface board, where the second notification message includes a second value, and the second value represents a second number of tokens;

the device further comprises: a deduction unit (not shown) for deducting the second number of tokens from the first token bucket according to the second number of tokens;

and the second number of tokens is obtained by judging whether tokens which meet the requirement of forwarding the second service message exist in the second token bucket after the second interface board receives the second service message.

Optionally, the apparatus further comprises: a second determining unit (not shown in the figure), configured to determine whether a third notification message sent by the second interface board has been received, where the third notification message includes a third value, and the third value indicates a third number of tokens;

the sending unit 530 is further configured to send the first notification message to the second interface board if the third notification message is received and the third number of tokens are deducted from the first token bucket according to the third number of tokens;

the sending unit 530 is further configured to not send the first notification message to the second interface board if the third notification message is not received.

Optionally, the apparatus further comprises: a third determining unit (not shown in the figure), configured to determine, within a preset time period, whether a fourth notification message sent by the second interface board has been received, where the fourth notification message includes a fourth value, and the fourth value indicates a fourth number of tokens;

the sending unit 530 is further configured to send the first notification message to the second interface board if the fourth notification message is received before the preset time period ends and the fourth number of tokens are deducted from the first token bucket according to the fourth number of tokens;

the sending unit 530 is further configured to not send the first notification message to the second interface board if the fourth notification message is not received within the preset time period or when the preset time period ends.

Optionally, the apparatus further comprises: a throwing unit (not shown in the figure) for throwing tokens into the first token bucket according to a preset throwing rate;

and the launching rate is not greater than the speed limit bandwidth of the first interface board.

Therefore, by applying the communication device provided by the present application, the first interface board receives the first service packet; according to the first service message, the first interface board judges whether a first token bucket has a first number of tokens which meet the requirement of forwarding the first service message; if yes, the first interface board forwards the first service message, and deducts a first number of tokens from the first token bucket; the first interface board sends a first notification message to the second interface board, wherein the first notification message comprises a first value, and the first value represents a first number of tokens, so that the second interface board deducts the first number of tokens from a second token bucket arranged in the second interface board; and the second interface board is positioned in the second frame.

Therefore, the interface boards in different frames only transmit the number of tokens deducted by the interface boards, and do not transmit the service messages mutually, so that the problems that the service messages are largely discarded and the working efficiency of a CPU is influenced in the process of transmitting the service messages mutually among the interface boards are solved. The token bucket processing performance is improved, and meanwhile, the consumption of a CPU and the pressure of inter-frame communication are reduced.
