Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. 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.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
In the process of implementing the technical scheme in the embodiment of the present invention, the inventor of the present invention finds that the prior art is as follows: network packets may be generally divided into streams, where a stream refers to a series of packets having the same source and destination IP, source and destination port, and protocol number. The network packet aggregation and distribution device is responsible for distributing the aggregated network packet to different devices (which may be hardware server groups or other processing modules inside a software system) of the service system, as shown in fig. 1. When distributing messages to a back-end processing system, it is required to send messages of the same flow to the same back-end processing machine, that is, all messages of the same flow need to be sent to the same back-end processing system from the same output port, which is called homogeneous co-homing in the flow splitting.
The general implementation of this shunting is as follows:
step 1: receiving a message, analyzing a message header, and taking a quintuple (a source destination IP, a source destination port and a protocol number) of the message;
step 2: performing hash calculation on the quintuple obtained in the step 1 according to a predetermined hash function to obtain a hash value N;
and step 3: and (3) further performing modulo operation on the hash value N obtained in the step (2), and taking the total number M of the output ports as a modulo to obtain a value L, wherein L is the output port number of the message (assuming that the port number starts from 0), namely the value range of L is 0-M-1.
And (3) the convergence and distribution equipment performs the steps 1 to 3 on each received message to complete the distribution work of homologous and homoclinic.
Further, the inventor of the present application finds that the current packet distribution method is simple and easy to implement, but has an inherent disadvantage that the traffic output of each output port may not be uniform. Because the streaming mode is distributed by using message streams as granularity, uniform distribution can be achieved in the stream dimension, but the size of different message streams (that is, the number of messages contained in a stream) is not considered to be different, for example, the size of a video stream is obviously different from that of an IM chat stream, so the streaming mode cannot perform accurate load balancing output at the message level. This problem can further lead to two problems: 1) the processing unit in the back-end service system receives inconsistent numbers of messages, which may cause uneven processing pressure of each processing unit, and the difference may exceed 5% and even reach 10%, thereby affecting the overall performance and stability of the processing unit; 2) in extreme cases, the aggregation and distribution device itself may cause packet loss phenomenon at individual interfaces, mainly when the traffic approaches the output peak value, the traffic received by the individual port exceeds other ports, so that the total output traffic of the individual port exceeds the limit of the output port, which may cause the device to discard an excessive part of messages. Further, the inventor finds that the existing convergence and shunt equipment performs load balancing output according to flows, so that the technical problem of uneven flow output of each output port is caused.
The inventor of the present application, in order to improve the above technical problems, invented the technical solutions provided in the embodiments of the present invention. Embodiments provided in embodiments of the present invention will be described in detail below with reference to specific examples and the accompanying drawings.
Referring to fig. 2, an embodiment of the present application provides a packet sending method, which is applied to a convergence and offloading device, where the convergence and offloading device includes a plurality of output ports, and the method may include: step S200, step S210, and step S220.
Step S200: and the convergence and diversion equipment receives the network message in the network message flow.
Step S210: and the aggregation and distribution equipment acquires the attribute information of the network message.
In the embodiment of the present application, the attribute information may include five tuples, i.e., source destination IP, source destination port, and protocol number.
Step S210 may include: the convergence and diversion device analyzes the message header of the network message to obtain the quintuple of the network message.
Step S220: and the convergence and diversion device judges whether the network message meets a preset output-allowed condition or not based on the attribute information, and if so, the convergence and diversion device determines a target output port corresponding to the network message from the plurality of output ports and outputs the network message through the target output port.
It is understood that in the embodiments of the present application, there are defined: the convergence and diversion device comprises M output ports, each output port in the M output ports is correspondingly provided with a token bucket, the initial value of the number of tokens in the token bucket is the maximum value Bc, the token filling speed is Tc, the filling interval is Sc, and Lc tokens are subtracted from the token bucket corresponding to the output port when the output port sends a message of Lc Bytes. If the number of the remaining tokens in the token bucket is larger than the preset constant, the output port can receive and output a new network message flow. The predetermined constant may be 0.
The convergence and diversion device establishes a flow table for the network message flow, establishes a flow table entry for a first message when receiving the first message of the network message flow, and records an output port of the message. The flow table has a size of C, and C may determine a specific numerical value according to the device memory and the network traffic scale, and generally C is on the order of tens of thousands to tens of millions.
Alternatively, referring to fig. 2 and fig. 3 in combination, step S220 may include: sub-step S221, sub-step S222, sub-step S2221, sub-step S2222, sub-step S2223, sub-step S2224, and sub-step S2225. Step S220 may also include sub-step S222 a.
Substep S221: and the aggregation and distribution equipment searches a flow table corresponding to the network message flow based on the attribute information.
Sub-step S222 a: if the aggregation and distribution device finds the flow table entry corresponding to the network message from the flow table, it indicates that the network message meets a preset allowable output condition.
In this embodiment of the present application, after searching for the flow table corresponding to the network packet flow based on the attribute information, the convergence and offloading device then searches for the flow table entry corresponding to the network packet from the flow table to further control selection of the output port, thereby implementing homologous co-location of packet distribution.
Further, referring to fig. 3, each of the output ports is configured with a token bucket, and after the sub-step S221, the method may further include:
substep S222: if the flow table entry corresponding to the network message is not found from the flow table, the aggregation and distribution device obtains an initial output port from the plurality of output ports based on the attribute information;
sub-step S2221 a: the aggregation and distribution equipment judges whether the number of tokens in a token bucket corresponding to the initial output port is greater than a preset constant, and if the number of tokens is greater than the preset constant, the aggregation and distribution equipment indicates that the network message meets a preset allowable output condition.
In the embodiment of the present application, the preset constant may be 0.
In the embodiment of the application, the convergence and shunt device determines that the number of tokens in the token bucket corresponding to the obtained initial output port is greater than a preset constant by correspondingly configuring the token bucket for each output port, and indicates that the initial output port is selected as a target output port of a network message, so that the message is not only uniformly output, but also homologized according to the flow.
Obtaining an initial output port from the plurality of output ports based on the attribute information may include:
taking the quintuple of the network message as a key, calculating to obtain a hash value, modulo M, and obtaining N which is L% M, wherein M is the total number of the output ports, L is the hash value, N is the initial output port, and the value range of N is 0- (M-1).
For example, the attribute information includes a quintuple, the convergence and offloading device executes steps S200 to S210 to obtain the quintuple of the network packet, looks up a flow table by using the quintuple of the network packet as a key, and if the result is found, indicates that the network packet belongs to an existing network packet flow; the aggregation and distribution equipment acquires an output port in a flow entry from the flow entry corresponding to the network message and determines the output port in the flow entry as a target output port corresponding to the network message; outputting the network message through the target output port, subtracting the length value of the network message from the number of tokens in the token bucket corresponding to the target output port, updating the flow entry timestamp, and going to step 200 to continue processing the next network message; if the corresponding flow entry is not found, it indicates that the network packet is the first packet of the network packet flow, and the process goes to substep S222, i.e., a hash value is calculated by using the five-tuple of the network packet as a key, and modulo M is taken, so as to preliminarily obtain an initial output port number N ═ L% M. M is the total number of the output ports, L is a hash value, N is the number of the initial output port, and the value range of N is 0- (M-1).
Further, after the step of determining, by the aggregation and offloading device, whether the number of tokens in the token bucket corresponding to the initial output port is greater than a preset constant, the method further includes:
substep S2221: if the aggregation and distribution equipment judges that the number of tokens is not greater than a preset constant, arranging a plurality of residual output ports except the initial output port from the plurality of output ports in a descending order according to the number of tokens in token buckets corresponding to the plurality of residual output ports, and selecting the residual output port arranged at the first position;
substep S2222: and the aggregation and distribution equipment judges whether the number of tokens in the token bucket corresponding to the first remaining output port is greater than the preset constant, and if so, the aggregation and distribution equipment indicates that the network message meets a preset allowable output condition.
In the embodiment of the application, the convergence and shunt device controls the selection of the target output port of the network message through the token bucket, so that the message is not only uniformly output, but also homodromous according to the flow.
It can be understood that, if the aggregation and offloading device determines that the number of tokens in the token bucket corresponding to the remaining output port arranged in the first place is not greater than the preset constant, it indicates that the network packet does not satisfy the preset allowable output condition, and discards the network packet.
As an embodiment, the determining, by the aggregation and offloading device, a target output port corresponding to the network packet from the plurality of output ports includes:
substep S2223: the aggregation shunt equipment determines the remaining output ports arranged at the first position as target output ports corresponding to the network messages;
substep S2224: and the aggregation and distribution equipment establishes a flow table item corresponding to the network message and stores the established flow table item in a flow table corresponding to the network message flow based on the attribute information and the remaining output ports arranged at the first position.
For example, the aggregation and offloading device establishes a flow entry for the network packet in a flow table by using a five-tuple of the network packet as a key, records the remaining output ports arranged in the first place in the flow entry, and stores the remaining output ports in the flow table corresponding to the network packet flow.
In the embodiment of the application, the aggregation and distribution device takes the number of messages of each message flow as a variable, dynamically selects a corresponding target output port according to the number of tokens in the token bucket, and stores a newly-built flow table item into the flow table, thereby providing a basis for directly inquiring the flow table to directly obtain the output port when other subsequent messages of the network message flow arrive, and further realizing uniform message output and simultaneous homing according to the flows.
The determining, by the aggregation and offloading device, a target output port corresponding to the network packet from the plurality of output ports and outputting the network packet through the target output port includes:
substep S2225: the convergence and diversion device outputs the network message through the target output port and subtracts the length value of the network message from the number of tokens in the token bucket corresponding to the target output port.
To further illustrate the effectiveness of the message sending method provided in the embodiment of the present application, the aggregation and offloading device is configured to include 5 output ports, which are respectively numbered as 1, 2, 3, 4, and 5. Each output port is correspondingly provided with a token bucket, and the token in each token bucket is full when the system is initialized. As the output port continuously receives the packet, the tokens in the token bucket are also consumed, and the number of tokens in the token bucket at a certain time is schematically shown in fig. 4: the current number of tokens at each output port is indicated by shading, and it can be seen that the number of tokens remaining at output port 2 is the largest at this time, and the token at output port 4 is used up.
For example, at this moment, the convergence and offloading device receives a network message stream, which is denoted as a first message of stream1, and a quintuple of the first message is: sip is 1.2.3.4; dip is 5.6.. 7.8; sport is 1234; 555 dport; and 7, according to the method provided by the application, the first message cannot find a corresponding flow table item from the flow table, and an initial output port is selected according to the five-tuple information hash. The initial output port obtained after the hash is the output port 4. As the token of output port 4 has been exhausted, a new flow of messages will no longer be accepted. So one of the remaining output ports No. 1, 2, 3, 5 is selected as the target output port. The four ports are sorted in descending order of the number of remaining tokens, and output port 2 is selected as the final target output port. A flow table is then established for the flow and relevant information is recorded. Flow table schematic 5 is as follows: the flow table is a hash table with N slots, and the flow table entry is hung under a certain slot in a linked list mode. The stream entry of the stream1 in this example is suspended in slot 2 of the stream table, and the content of the stream entry is as shown in fig. 5.
In this embodiment, all output messages need to consume tokens in the token bucket, and the load between each interface is controlled by the token bucket algorithm, so that a new message stream is reasonably scheduled, and the output uniformity of each output port is realized.
As another embodiment, after the sub-step S2221a, the step S220 further includes: the aggregation and offloading device determines a target output port corresponding to the network packet from the plurality of output ports, and further includes:
sub-step S2221a 1: the convergence and diversion device determines the initial output port as a target output port corresponding to the network message;
sub-step S2221a 2: and the aggregation and distribution equipment establishes a flow table entry corresponding to the network message based on the attribute information and the initial output port and stores the established flow table entry in a flow table corresponding to the network message flow.
In the embodiment of the application, the aggregation and distribution device takes the number of messages of each message flow as a variable, dynamically selects a corresponding target output port according to the number of tokens in the token bucket, and stores a newly-built flow table item into the flow table, so that a foundation is provided for directly inquiring the flow table to directly obtain the output port when other subsequent messages of the network message flow arrive, and therefore, the messages are not only uniformly output, but also homologously received according to the flow.
For example, the aggregation and offloading device establishes a flow entry for the network packet in a flow table by using a five-tuple of the network packet as a key, records the initial output port in the flow entry, and stores the initial output port in a flow table corresponding to the network packet flow.
In the embodiment of the application, the aggregation and distribution device takes the number of messages of each message flow as a variable, dynamically selects a corresponding target output port according to the number of tokens in the token bucket, and stores a newly-built flow table item into the flow table, so that a foundation is provided for directly inquiring the flow table to directly obtain the output port when other subsequent messages of the network message flow arrive, and therefore, the messages are not only uniformly output, but also homologously received according to the flow.
In the embodiment of the application, all output messages need to consume tokens in the token bucket, and the load among all interfaces is controlled through the token bucket algorithm, so that the new message flow is reasonably scheduled, and the output uniformity of all output ports is realized.
As another implementation manner, after the sub-step S222a, the step S220 may further include that one of the plurality of output ports is stored in a flow table entry corresponding to the network packet, and the determining, by the aggregation and offloading device, a target output port corresponding to the network packet from the plurality of output ports further includes:
sub-step S222a 1: and the aggregation and distribution equipment acquires an output port in the flow table entry from the flow table entry corresponding to the network message and determines the output port in the flow table entry as a target output port corresponding to the network message.
In the embodiment of the application, the convergence and shunt device outputs the network message through dynamically selecting the corresponding target output port in a flow table entry mode, so that the message is not only uniformly output, but also homodromous according to the flow.
It can be understood that, with reference to fig. 2 and fig. 3, according to the actual situation of the received network packet, the convergence and offloading device executes step S200, step S210, sub-step S221, sub-step S222, sub-step S2221, sub-step S2222, sub-step S2223, sub-step S2224, and sub-step S2225 to implement the method; or the convergence and offloading device executes step S200, step S210, sub-step S221, sub-step S222, sub-step S2221a, sub-step S2221a1, sub-step S2221a2, and sub-step S2225 to implement the method; or the convergence and offloading device executes step S200, step S210, sub-step S221, sub-step S222a, sub-step S222a1, and sub-step S2225 to implement the method.
The convergence and shunt device adds a token bucket for each output port, and reasonably selects the output port for the message flow through the token bucket. When performing quintuple hash on a packet to select an output port, it is necessary to further check whether a packet token bucket corresponding to the selected output port allows output, and if there is no token in the token bucket, the output port cannot be selected as the output port of the packet flow. And selecting one of the other output ports with the remaining tokens as a final output port. Namely, the token bucket influences the output port selection of the message flow, and the problem of uneven distribution caused by flow output is avoided, so that the purposes of homoclinic according to the flow and uniform message output are achieved.
In the embodiment of the application, a flow table is added to ensure the same source and the same destination of the message distribution. The invention can form the secondary selection of the output port after adding the port token bucket, therefore in order to guarantee the homologous homologism of message distribution, establish a flow table entry for each message flow when receiving the first message of the message flow, and record the output port selected according to the method of the invention in the flow table, the flow table of direct inquiry is outputted according to the output port recorded when the subsequent other message of the flow arrives. Thereby ensuring the same source and sink output of message distribution. The method realizes the distribution according to the stream and the balanced output according to the number of the messages, and realizes the accurate and uniform distribution of the whole message.
Further, the method may further include:
and the aggregation and distribution equipment checks whether the filling time interval of the token bucket is overtime, and if so, at least one token is added to the token bucket corresponding to each output port in the plurality of output ports.
In the embodiment of the application, the aggregation and distribution device further realizes that the message is not only output uniformly, but also homodromous according to the flow through a mode of periodically adding token quantity of the token bucket.
For example, please refer to fig. 6, the aggregation and offloading device sets a token addition timer interval Sc, checks whether a filling time interval of the token bucket is overtime, if so, sequentially adds Tc tokens to the token bucket corresponding to each of the output ports, sleeps for 10ms, and continues timing check.
Further, to avoid the flow table space being exhausted, the method further comprises:
the aggregation shunt device scans the corresponding flow table of the stored network message flow at regular time, and if the overtime flow table item is detected, the overtime flow table item is removed from the flow table where the overtime flow table item is located.
For example, please refer to fig. 7, the aggregation and offloading device sets a flow table timeout time, reads a flow table corresponding to a stored network packet, scans the flow table from a header of the flow table, compares a timestamp in a flow entry of the flow table with a current time, deletes the timeout flow entry from the flow table where the timeout flow entry is located if the timeout flow entry is detected, determines whether a tail of the flow table is reached, continues to detect a next flow entry in the flow table if the tail of the flow table is not reached, and reads a new flow table for detection if the tail of the flow table is reached.
In the embodiment of the application, the convergence and shunt device avoids the consumption of the flow table space by setting the overtime management mode of the flow table, so as to further realize that the message is not only output uniformly, but also co-hosted according to the flow homology.
When the convergence and shunt device performs hash selection on the message flow to output ports, the number of messages of each flow, namely the size of the flow, is also taken into consideration as a variable, when the output ports are selected for the newly-built flow, the current output flows of all the output ports are considered in a whole disc mode, and when the flow output by a certain port is overlarge, the message flow selects a port with the minimum output quantity from other output ports as the output port. Selection control of the output ports is achieved by setting a token bucket for each output port. If tokens exist in the token bucket corresponding to the port selected for the first time, allowing the port to output, and directly selecting the port; and if the number of tokens in the token bucket corresponding to the port is less than or equal to 0, the message flow can not be accepted and output from the port. And selecting one output port with the most tokens left as a final output port from other output ports with the tokens left in the token bucket. And each flow selects a port and establishes a flow table when in the first message, and the output port is stored in the flow table. When the subsequent message of the flow arrives, the output port in the flow table is directly searched for output, and the same source and the same destination of the flow are achieved.
The embodiment of the application provides a message sending method, which comprises the steps that a convergence and shunt device judges whether a network message meets a preset output permission condition or not based on acquired attribute information of the network message, and then determines a target output port corresponding to the network message from a plurality of output ports and outputs the network message through the target output port when the network message meets the preset output permission condition, so that the technical problem that the flow output of each output port is uneven due to the fact that the current convergence and shunt device carries out load balancing output according to flows is solved.
