Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
In a distributed system, in order to ensure high availability of the system, a low-latency dynamic flow control strategy is needed to dynamically control the delivery of traffic to multiple customers based on the processing power of the service provider.
The embodiment of the application provides electronic equipment, which can be a service providing end, such as server equipment. Referring to fig. 1, a schematic structure of an electronic device is shown. The electronic device comprises a processor 10, a memory 11, a bus 12. The processor 10 and the memory 11 are connected by a bus 12, the processor 10 being adapted to execute executable modules, such as computer programs, stored in the memory 11.
The processor 10 may be an integrated circuit chip with signal processing capabilities. In implementation, the steps of the flow control method may be performed by integrated logic circuitry in hardware or instructions in software in the processor 10. The processor 10 may be a general-purpose processor, including a central processing unit (Central Processing Unit, CPU for short), a network processor (Network Processor, NP for short), etc.; but may also be a digital signal Processor (DIGITAL SIGNAL Processor, DSP), application Specific Integrated Circuit (ASIC), field-Programmable gate array (FPGA) or other Programmable logic device, discrete gate or transistor logic device, discrete hardware components.
The memory 11 may comprise a high-speed random access memory (RAM: random Access Memory) or may further comprise a non-volatile memory (non-volatile memory), such as at least one disk memory.
Bus 12 may be ISA (Industry Standard Architecture) bus, PCI (Peripheral Component Interconnect) bus, EISA (Extended Industry Standard Architecture) bus, or the like. Only one double-headed arrow is shown in fig. 1, but not only one bus 12 or one type of bus 12.
The memory 11 is used to store programs, such as programs corresponding to the flow control devices. The flow control means comprise at least one software function module which may be stored in the memory 11 in the form of software or firmware (firmware) or cured in the Operating System (OS) of the electronic device. The processor 10, upon receiving the execution instruction, executes the program to implement the flow control method.
Possibly, the electronic device provided by the embodiment of the application further comprises a communication interface 13. The communication interface 13 is connected to the processor 10 via a bus. In one possible implementation, the electronic device may establish long connections with other devices or terminals through the communication interface 13.
It should be understood that the structure shown in fig. 1 is a schematic structural diagram of only a portion of an electronic device, which may also include more or fewer components than shown in fig. 1, or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
The flow control method provided by the embodiment of the application can be applied to, but is not limited to, the electronic device shown in fig. 1, and the specific flow is shown in fig. 2:
S102, adjusting the number of data receiving units corresponding to the first target terminal according to a preset adjustment threshold to determine the first target number.
The first target terminal is a service consumption terminal in a positive state.
It should be noted that, the data receiving unit belongs to the service providing end, and is configured to receive the data packet sent by the target terminal, and may be understood as a network access token. When the first target terminal is allocated with a data receiving unit (network access token), the first target terminal can establish a corresponding long connection to send a message.
It can be understood that the service consumer in the active state is the service consumer that sends the data message (except the heartbeat monitoring message) to the service provider at the current time, and may be a mobile phone, a computer or other servers.
The number of data receiving units corresponding to the first target terminal, that is, the adjusted first target number, is related to the request processing capability of the service providing end for the first target terminal, and the more the number is, the stronger the processing capability is.
S103, generating a first flow limit message according to the first target quantity, and sending the first flow limit message to the first target terminal.
The first flow limit message includes a first target number and an upper flow limit, where the upper flow limit is an upper flow limit that can be received by the data receiving unit.
It can be appreciated that the product of the first target number and the upper traffic limit is the maximum traffic limit allocated to the first target terminal by the service provider. The sending traffic of the first target terminal in one call cannot exceed the maximum traffic limit.
And adjusting the corresponding first target quantity in real time for the service consumption terminal in the active state, namely adjusting the maximum flow limit corresponding to the first terminal. The service providing end can provide service for the service consuming end in a positive state better. Meanwhile, by sending the first flow limit message in real time, the situation that the sending flow of the first target terminal exceeds the maximum flow limit in one call is avoided, downtime is avoided, and the usability of the system is guaranteed.
In summary, an embodiment of the present application provides a flow control method, which is applied to a service providing end, including: adjusting the number of data receiving units corresponding to the first target terminal according to a preset adjustment threshold value to determine a first target number; the method comprises the steps that a first target terminal is a service consumption terminal in a positive state, a first flow limit message is generated according to a first target quantity, and the first flow limit message is sent to the first target terminal; the first flow limit message includes a first target number and an upper flow limit, where the upper flow limit is an upper flow limit that can be received by the data receiving unit. And adjusting the corresponding first target quantity in real time for the service consumption terminal in the active state, namely adjusting the maximum flow limit corresponding to the first terminal. The service providing end can provide service for the service consuming end in a positive state better. Meanwhile, by sending the first flow limit message in real time, the situation that the sending flow of the first target terminal exceeds the maximum flow limit in one call is avoided, downtime is avoided, and the usability of the system is guaranteed.
For the first flow restriction message, a possible implementation manner is also provided in the embodiments of the present application, please refer to the following.
Request ID(64bits)l Data Length(32bits)l Version(8bits)l Allow Flows Of Each Package(32bits)l Allow Packages(8bits)
The packet Header (Header) is 144bits fixed length;
Request ID (64 bits): identifying a unique request;
DATA LENGTH (32 bits): the length (variable part) of the content after serialization is counted in bytes;
version (8 bits): identifying a protocol version number;
Allow Flows Of EACH PACKAGE (32 bits): the data unit flow size defined by the service providing end;
Allow Packages (8 bits): the service provider allows the number of data units of the received data.
In one possible implementation, the adjustment threshold includes a first threshold that is a total number of data receiving units within the service provider. With respect to the content in S102 on the basis of fig. 2, the embodiment of the present application further provides a possible implementation manner, please refer to fig. 3, S102 includes:
s102-1, determining a first threshold as a first target number in the case that the first target terminal is a service consumer initially connected to the service provider.
Optionally, the service provider needs to define (or configure) its own traffic rules before providing the service: defining each data unit size (X), the maximum data unit allowed by the provider (Y), the maximum acceptable flow rate of the provider (Z), satisfying the definition of z=x×y; after the first service consumer long connection is established, the first request returns the full processing power of the provider: z=x×y; i.e. the first threshold value is determined as the first target number. And sending the first flow limit message carrying the first target number to the first target terminal.
In one possible implementation, the adjustment threshold includes a second threshold. With respect to the content in S102 on the basis of fig. 2, the embodiment of the present application further provides a possible implementation manner, please refer to fig. 4, S102 includes:
S102-2, determining the sum of the current number of the first target terminals and the second threshold value as the first target number when other service consumption terminals are connected to the service providing terminal.
The current number of the first target terminals is the number of data receiving units corresponding to the first target terminals.
For example, the number of data receiving units currently corresponding to the first target terminal is 1, the second threshold is N, and the first target number is 1+n.
On the basis of fig. 4, regarding how to determine the second threshold, a possible implementation manner is further provided in the embodiment of the present application, referring to fig. 5, the flow control method further includes:
S101, determining a second threshold according to the number of data receiving units corresponding to the service consumers connected to the service provider.
Because the total number of data receiving units within the service provider is fixed, i.e. the first threshold is fixed. In the case where the number of data reception units corresponding to the first target terminal increases, it is necessary to have the number of data reception units corresponding to the other terminals decrease.
On this basis, with respect to how to balance the distribution of the data receiving units, the embodiment of the present application further provides a possible implementation manner, please refer to fig. 6, and the flow control method further includes:
s104, sending a second flow limit message to the second target terminal.
The second target terminal is a service consumption terminal with the maximum number of corresponding data receiving units except the first target terminal, the second traffic limiting message comprises a second target number and a traffic upper limit, the second target number is the difference between the current number of the second target terminal and a second threshold value, and the current number of the second target terminal is the number of the data receiving units corresponding to the second target terminal.
Specifically, as shown in fig. 7, it is assumed that there is currently a service consumer O, P, Q and R is connected to a service provider. The number of data receiving units corresponding to the service consumption end O is 3; the number of the data receiving units corresponding to the service consumption end P is 1; the number of data receiving units corresponding to the service consumption end Q is 4; the number of data receiving units corresponding to the service consumer R is 2.
The service consumption end in the active state is P, namely P is used as a first target terminal. At this time, the service consumer having the largest number of corresponding data receiving units except P is Q, i.e., Q is the second target terminal. The second target number is 4-N and the first target number is 1+N.
In one possible implementation, when the current number of second target terminals is equal to the minimum threshold (Ymin), the number of second target terminals corresponding data receiving units cannot be acquired any more. The second threshold is now adjusted to 0. Otherwise, the second target terminal is limited in current, and can never send a request to the service provider.
In one possible implementation, for example, one service consumer a sends packets fastest, and the traffic is the largest, and is the consumer with the largest maximum traffic ratio, and the other service consumers reach the minimum Ymin, then the service consumer a cannot get to the data receiving unit on the service consumer with the other Ymin.
Optionally, regarding policy enforcement, the number of data receiving units needs to be adjusted, and there must be one service consumer request to be reached, which affects at most the two consumers' notification about Y value change: a requested service consumer (first target terminal) and an adapted service consumer (second target terminal). The Y value change of the requested service consumer is returned to the service consumer along with the request response data, and the adjusted service consumer is actively initiated by the producer to be pushed to the service consumer once.
In one possible implementation manner, after receiving the flow limitation message (the first flow limitation message or the second flow limitation message), the server consumer calculates whether the size of the total packet exceeds the maximum limit allowed by the server through quota data in the flow limitation message: z=x×y; if the packet is exceeded, unpacking is executed (the big data packet is split into a plurality of small data packets) or the subsequent small data packets are executed, and the big data packet executes a retry strategy; whether the server consumer can perform unpacking and whether there is a subsequent small packet or not requires that the entire cluster be reasonably evaluated in connection with the traffic when defining the size (X) of each data unit.
Referring to fig. 8, fig. 8 is a schematic diagram illustrating an embodiment of a flow control device according to the present application, and the flow control device is optionally applied to the electronic apparatus described above.
The flow control device includes: a processing unit 201 and a transmitting unit 202.

The first target terminal is a service consumption terminal in a positive state.
Alternatively, the processing unit 201 may execute S102 described above.
The sending unit 202 is configured to generate a first traffic limitation message according to the first target number, and send the first traffic limitation message to the first target terminal.
