Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the drawings are described in detail below.
In order to facilitate understanding of the technical solutions provided in the present application, the following description will first be made on the background art related to the present application.
Because QoS processing mostly limits the forwarding speed of a certain type of packet, such a packet is usually received by multiple forwarding cores. When limiting the speed of such a packet, it is necessary to count the relevant information (i.e., qoS rules corresponding to the packet) of the packet received by multiple forwarding cores, where the relevant information is multi-core contention resources. In order to avoid resource contention, locking is inevitably required during multi-core processing, so that a frequent locking process is involved when the multi-core forwarding system performs QoS processing, and the process affects normal flow packet forwarding, so that the overall forwarding performance is reduced.
Based on this, the embodiment of the present application provides a method for implementing QoS processing of a message, where when performing QoS processing of a message, a QoS rule is designed as a local resource, each forwarding core only processes a message corresponding to a QoS rule allocated to the forwarding core, and a plurality of forwarding cores do not receive a message matching the same QoS rule at the same time, so that QoS processing can be performed in a multi-core concurrent manner without any lock, and concurrency performance of QoS processing is improved. And the QoS rule limited by the source IP address is distributed to the forwarding core for processing, and the QoS rule limited by the destination address is distributed to the QoS thread processing, namely the QoS rule with more complex scheduling is distributed to the QoS thread processing, so that the forwarding of the normal flow message of the forwarding core is prevented from being influenced, and the overall forwarding performance is improved.
The QoS rule indicates that a certain packet or a certain type of packet is limited for receiving or transmitting, so as to regulate and control network traffic, avoid and manage network congestion, reduce the packet loss rate, and provide a dedicated bandwidth for enterprise users or provide differential services for different services (voice, video, data, etc.).
Based on the above description, the method for implementing QoS processing for a packet provided by the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, which is a flowchart of a method for implementing QoS (quality of service) processing of a packet according to an embodiment of the present disclosure, as shown in fig. 1, the method is applied to a multi-core forwarding system, where the multi-core forwarding system includes a configuration core and N forwarding cores, and the method may include:
s101: the configuration core divides the QoS rules in the first set and the first QoS rules in the third set into N first rule sets, the N first rule sets are distributed to N forwarding cores, and each forwarding core corresponds to one first rule set.
In this embodiment, the configuration core may divide the QoS rule into three sets, that is, a first set, a second set, and a third set, based on the IP address corresponding to the QoS rule. The QoS rules in the first set are QoS rules for limiting source IP addresses, the QoS rules in the second set are QoS rules for limiting destination IP addresses, and the QoS rules in the third set are QoS rules for limiting both source IP addresses and destination IP addresses.
For example, rule 1 in the first set: the source IP address (1.1.1.1-1.1.1.5) and the a restriction indicate that a type of rule restriction is performed on a packet sent by the source IP address (1.1.1.1-1.1.1.5), and for convenience of description, each rule only exemplifies a restricted source IP address and/or a restricted destination IP address, and a type of restriction included in the rule is not further exemplified; rule 2: the source IP address is (1.1.1.6-1.1.1.15); rule 3: source IP address (2.2.1.1-2.2.3.5). Rule 1 in the second set: destination IP address (2.2.2.2-2.2.2.5); rule 2: destination IP address (4.4.4.4); rule 3: destination IP address (5.5.5.5). Rule 1 in the third set: source IP address (8.8.8.8), destination IP address (2.2.2.2); rule 2: source IP address (2.2.3.4), destination IP address (2.2.2.4-2.2.2.5).
After the three sets are divided, the configuration core divides all the QoS rules in the first set and the first QoS rules in the third set into N first rule sets, and allocates one first rule set for each forwarding core. The first QoS rule is a QoS rule that a source IP address is completely coincident with a source IP address in any one QoS rule in the first set, and N is a positive integer and is greater than or equal to 2. The complete overlapping means that the source IP address corresponding to the first QoS rule completely belongs to the source IP address corresponding to a certain QoS rule in the first set. For example, the source IP address corresponding to QoS rule C in the third set is (1.2.2.3-1.2.2.4), and the source IP address corresponding to QoS rule a in the first set is (1.2.2.1-1.2.2.5), then QoS rule C completely coincides with QoS rule a. If QoS rule C corresponds to a source IP address of (1.2.2.3-1.2.2.6), then QoS rule C does not perfectly coincide with QoS rule A.
Specifically, the existing first QoS rule is determined from the third set, and then the first QoS rule is divided into the first rule set corresponding to the QoS rule in the first set which completely coincides with the source IP address of the first QoS rule. For example, the source IP address corresponding to the QoS rule P in the third set is (2.2.2.3-2.2.2.4), the source IP address corresponding to the QoS rule Q in the first set is (2.2.2.1-2.2.2.5), and since the source address of the QoS rule P completely coincides with the source IP address of the QoS rule Q, the QoS rule P is the first QoS rule, and the QoS rule P is divided into the first rule set to which the QoS rule Q belongs. The specific implementation of S101 will be described in detail in the following embodiments.
S102: the configuration core divides the QoS rules in the second set and other QoS rules in the third set into M second rule sets, and distributes each second rule set to M QoS threads respectively, wherein each QoS thread corresponds to one second rule set.
The configuration core divides the QoS rules in the second set and other QoS rules in the third set into M second rule sets, and allocates one second rule set to each QoS thread, so that each thread only processes the message of the destination IP address in the corresponding second rule set. The QoS thread can run on a forwarding core or a non-forwarding core, the second set comprises QoS rules for limiting the destination IP address, and M is a positive integer and is greater than or equal to 2. The other QoS rules in the third set refer to the QoS rules in the third set except for the first QoS rules.
An implementation manner of obtaining M second rule sets will be described in the following embodiments.
S103: and after acquiring the first rule set, the forwarding core sets filtering conditions for the corresponding network card receiving queue so as to enable the forwarding core to receive the message sent by the source IP address in the first rule set corresponding to the forwarding core, and process the message according to the QoS rule in the first rule set corresponding to the forwarding core.
After each forwarding core is allocated to a first rule set, the forwarding core sets a filtering condition for the corresponding network card receiving queue according to the allocated first rule set, and the filtering condition can enable the forwarding core to receive a message sent by a source IP address in the corresponding first rule set.
In specific implementation, the binding of the rule and the forwarding core may be implemented through the network card hardware filter set, specifically, when each network card is configured with the receiving queue, a full connection relationship is established with the forwarding core, and the rule is configured for each network card. The receiving queue 1 of each network card is configured with a first rule set 1, so that all messages meeting the QoS rule in the first rule set 1 are distributed to the receiving queue 1, and the receiving queue 1 is distributed to the forwarding core 1 for processing; the receiving queue 2 of each network card is configured with a first rule set 2, so that all messages meeting the QoS rule in the first rule set 2 are distributed to the receiving queue 2, and the receiving queue 2 is distributed to the forwarding core 2 \8230, and the receiving queue N of each network card is configured with a first rule set N, so that all messages meeting the QoS rule in the first rule set N are distributed to the receiving queue N, and the receiving queue is distributed to the forwarding core N for processing.
That is, the QoS rule restricted by the source IP address is allocated to each forwarding core, so that the QoS rule corresponding to each forwarding core is a local resource, and each forwarding core processes the packet corresponding to the allocated QoS rule without lock, thereby implementing contention-free resources among multiple cores, and enabling the overall performance of the multi-core system to increase linearly with the increase of the number of forwarding cores.
S104: and the forwarding core or non-forwarding core where the QoS thread is located sends the message of the destination address in the second rule set corresponding to the QoS thread, and the message is processed according to the Qos rule in the second rule set corresponding to the QoS thread.
And after the configuration core allocates a second rule set to each QoS thread, the forwarding core or non-forwarding core where the QoS thread is located sends the message of the destination address in the second rule set corresponding to the forwarding core or non-forwarding core to the configuration core, and the packet sending processing is carried out according to the QOS rule in the corresponding second rule set.
Specifically, M QoS threads run in M forwarding cores or M non-forwarding cores respectively, each QoS thread establishes a sending queue with each network card respectively, the forwarding core or non-forwarding core where the QoS thread is located receives a message, determines a corresponding QoS rule according to a destination address of the message, and sends the message to the network card through the sending queue corresponding to the QoS rule.
It should be noted that, in a normal case, since the logic for processing the abnormal traffic is relatively complex, in order to avoid the influence of the abnormal traffic on the forwarding of the normal traffic, the QoS thread is run in the non-forwarding core.
In addition, the reason that the QoS rule for limiting the source IP address is processed by the forwarding core, and the QoS rule for limiting the destination IP address line is processed by the QoS thread is that the flow size of the source IP address client is mainly controlled for the QoS rule, and the limitation for the source IP address is also set by a user in most cases, so that the forwarding of the source IP address message is limited by hardware (the forwarding core). The distribution by the processing mode can ensure that the forwarding core can process the message limited to the source IP address as far as possible, thereby ensuring the forwarding performance.
According to the above description, all the QoS rules of the first set and part of the QoS rules of the third set are uniformly distributed to N forwarding cores according to the preset rules, so that the rules become per-core resources, and thus, a message received by each forwarding core is a message corresponding to the allocated QoS rule, and a plurality of forwarding cores do not simultaneously receive a message corresponding to one QoS rule. In addition, all the QoS rules of the second set and part of the QoS rules of the third set are distributed to M QoS threads uniformly, namely, the threads process the messages corresponding to the target address related rules. That is, the QoS rule operation related to the processing source IP address is allocated to the forwarding core for processing, and the QoS rule operation related to the processing destination address is allocated to the QoS thread for processing, so as to avoid the influence on normal traffic forwarding.
In one possible implementation manner, the dividing, by the configuration core, the QoS rules in the first set and the first QoS rules in the third set into N first rule sets includes: the configuration core changes the QoS rules in the first set into N first rule sets; and extracting the first QoS rules in the third set, and dividing each first QoS rule into the first rule sets corresponding to the QoS rules completely coincident with the source IP addresses of the first QoS rules in the first set.
That is, the QoS rules in the first set are divided into N first rule sets, then, for any QoS rule in the third set, it is determined whether the source IP address corresponding to the QoS rule completely coincides with the source IP address corresponding to a certain QoS rule (QoS rule X) in the first set, if yes, the QoS rule is determined to be the first QoS rule, and the first QoS rule is divided into the first rule set to which the QoS rule X belongs.
For example, the third set includes QoS rules as-rule 1: source IP address (1.1.1.2-1.1.1.5), destination IP address (4.4.4.4); rule 2: source IP address (1.1.1.4-1.1.1.7), destination IP address (5.5.5.5); wherein rule X in the first set: the source IP address (1.1.1.1-1.1.1.5) and rule X is in the Y-th first rule set. Since the source IP address corresponding to rule 1 in the third set completely coincides with the source IP address of rule X in the first set, rule 1 in the third set is a first QoS rule, and the first QoS rule is classified into the Y-th first rule set.
In a specific implementation, when the QoS rules in the first set are divided into N first rule sets, each forwarding core should share one first rule set, and the number of source IP addresses in each first rule set is guaranteed to be the same as much as possible when dividing in consideration of load balancing of the forwarding cores, so that load balancing of the whole multi-core forwarding system is guaranteed. The method specifically comprises the following steps: the configuration core divides the QoS rules in the first set into N first rule sets according to the source IP address number of each QoS rule in the first set.
For example, there are 3 forwarding cores coexisting, and the first set includes 4 QoS rules, rule 1: source IP address (1.1.1.1-1.1.1.10); rule 2: the source IP address is (1.1.1.6-1.1.1.11); rule 3: source IP address (2.2.3.1-2.2.3.4); rule 4: source IP address (2.2.2.5-2.2.2.16). It can be seen that rule 1 corresponds to 10 source IP addresses, rule 2 corresponds to 5 source IP addresses, rule 3 corresponds to 4 source IP addresses, and rule 4 corresponds to 11 source IP addresses, and to ensure that the number of source IP addresses included in each of the divided 3 first rule sets is as equal as possible, rule 1 may be divided into the 1 st first rule set, rule 2 and rule 3 may be simultaneously divided into the 2 nd first rule set, and rule 4 may be divided into the 3 rd first rule set.
In a possible implementation manner, the implementation process will be described with reference to a specific implementation of S102 in conjunction with the accompanying drawings.
Referring to fig. 2, which is a flowchart of a method for obtaining a second rule set according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:
s201: the configuration core extracts the second QoS rule in the third set.
In this embodiment, the configuration core determines the second QoS rule according to the destination IP address corresponding to each rule in the third set, so as to extract the second QoS rule. And the second QoS rule is a QoS rule of which the destination IP address is completely coincident with the destination IP address in any QoS rule in the second set. It should be noted that, at this time, the third set is a set that does not include the first QoS rule, that is, the configuration core determines the second QoS rule from other QoS rules of the third set.
For example, the QoS rules included in the third set at this time are rule C1: source IP address (8.8.8.8), destination IP address (2.2.2.2); rule C2: source IP address (9.9.9.9), destination IP address (2.2.2.4-2.2.2.5); rule C3: source IP address (7.7.7.7), destination IP address (3.3.3.3); rule C4: the source IP address (6.6.6.6) and the destination IP address (2.2.2.2.2-2.2.2.6). The second set includes QoS rules that are rule B1: destination IP address (2.2.2.2-2.2.2.5); rule B2: the destination IP address (4.4.4.4). Since the destination IP address corresponding to the rule C1 in the third set completely coincides with the destination IP address corresponding to the rule B1 in the second set, the rule C1 in the third set is the second QoS rule, and the destination IP address corresponding to the rule C2 in the third set completely coincides with the destination IP address corresponding to the rule B1 in the second set, and the rule C2 in the third set is also the second QoS rule.
S202: and extracting the QoS rules of which the destination IP addresses in the third set and the second set are not coincident completely to form a fourth set.
In this embodiment, after the configuration core extracts the second QoS rule from the third set, the QoS rule in which the destination IP address corresponding to the QoS rule and the destination IP address corresponding to each QoS rule in the second set do not overlap completely is extracted from the remaining QoS rules. And simultaneously, the configuration core extracts the QoS rules of which the destination IP addresses corresponding to the QoS rules are completely not overlapped with the destination IP addresses in each QoS rule in the third set from the second set. Then, the QoS rules satisfying the conditions extracted from the third set and the QoS rules satisfying the conditions extracted from the second set are combined into a fourth set.
Specifically, the configuration core extracts a third QoS rule of a third set (excluding the second QoS rule), extracts a fourth QoS rule of the second set, and combines the third QoS rule and the fourth QoS rule into the fourth set. The third QoS rule is a QoS rule that the destination IP address is not overlapped with the destination IP address in each QoS rule in the second set completely; the fourth QoS rule is a QoS rule whose destination IP address does not completely coincide with the destination IP address in each QoS rule in the third set.
For example, the third set (including the second QoS rules) includes QoS rules that are rule C1: source IP address (8.8.8.8), destination IP address (2.2.2.2); rule C2: source IP address (9.9.9.9), destination IP address (2.2.2.4-2.2.2.5); rule C3: source IP address (7.7.7.7), destination IP address (3.3.3.3); rule C4: the source IP address (6.6.6.6) and the destination IP address (2.2.2.2.2-2.2.6); rule C5: the source IP address (5.5.5.5) and the destination IP address (3.3.3.3).
The second set includes QoS rules that are rule B1: destination IP address (2.2.2.2-2.2.2.5); rule B2: destination IP address (4.4.4.4). Since the destination IP address corresponding to the rule C1 in the third set completely coincides with the destination IP address corresponding to the rule B1 in the second set, the rule C1 in the third set is the second QoS rule, and the destination IP address corresponding to the rule C2 in the third set completely coincides with the destination IP address corresponding to the rule B1 in the second set, and then the rule C2 in the third set is also the second QoS rule. That is, rule C1 and rule C2 are second QoS rules, in which case rule C3, rule C4, and rule C5 are included in the third set.
Since rule C3 and rule C5 do not have completely coincident destination IP addresses with both rule B1 and rule B2 in the second set, rule C3 and rule C5 are third QoS rules. Since the destination IP address corresponding to rule B2 in the second set does not completely coincide with the destination IP addresses corresponding to rule C3, rule C4, and rule C5, rule B2 is a fourth QoS rule. That is, the fourth set = { rule C3, rule C5, rule B2}.
S203: and extracting the QoS rules of which the destination IP addresses are partially overlapped in the third set and the second set to form a fifth set.
In this embodiment, after the second QoS rule and the third QoS rule are extracted from the third combination, the QoS rule in which the destination IP address corresponding to the QoS rule partially coincides with the destination IP address corresponding to any QoS rule in the second set is extracted from the third set. Meanwhile, the configuration core extracts the QoS rule of which the destination IP address corresponding to the QoS rule is partially overlapped with the destination IP address in any QoS rule in the third set from the second set. Then, the QoS rules satisfying the conditions extracted from the third set and the QoS rules satisfying the conditions extracted from the second set are combined into a fifth set.
Specifically, the configuration core extracts a fifth QoS rule in the third set, extracts a sixth QoS rule in the second set, and merges the fifth QoS rule and the sixth QoS rule into a fifth set. The fifth QoS rule is a QoS rule of which the destination IP address is partially overlapped with the destination IP address in any QoS rule in the second set; the fourth QoS rule is a QoS rule in which the destination IP address partially coincides with the destination IP address in any QoS rule in the third set.
For example, after the above-mentioned series of extraction operations, only the rule C4 remains in the third set, and the destination IP address corresponding to the rule C4 is (2.2.2.2-2.2.2.6), and only the rule B1 remains in the second set, and the destination IP address corresponding to the rule B1 is (2.2.2.2-2.2.5). Thus, rule C4 is the fifth QoS rule and rule B1 is the sixth QoS rule, i.e., the fifth set = { rule B1, rule C4}.
S204: and dividing the QoS rules in the fourth set into M-1 second rule sets.
S205: the QoS rules in the fifth set are determined to be 1 second set of rules.
And after the fourth set and the fifth set are determined, dividing the QoS rules in the fourth set into M-1 second rule sets, and determining all the QoS rules in the fifth set as 1 second rule set, thereby determining M second rule sets.
S206: and dividing each second QoS rule into a second rule set corresponding to the QoS rule completely coincident with the destination IP address of the second QoS rule in the second set.
After M second rule sets are determined, for each determined second QoS rule, dividing each second QoS rule into a second rule set corresponding to the QoS rule completely coincident with the destination IP address of the second QoS rule in the second set.
Through the method, the configuration core can divide the QoS rules in the second set and other QoS rules in the third set into M second rule sets.
For facilitating understanding of the specific implementation flow of the present application, refer to a frame diagram of implementing QoS for packet service shown in fig. 3. Firstly, configuring N forwarding cores and M QoS threads for a firewall, and sorting all QoS rules based on IP addresses into a binary group (source IP address sip, destination IP address dip) set, specifically, three categories. One is to limit the source IP address, and the destination IP address is arbitrary and is represented by (sip, any, count) sip 0), forming set a (first set); wherein, count sip Representing the number of source IP addresses, if sip is the network segment, count sip Equal to the number of IP addresses of the network segment, if sip is a single IP address, count sip Is 1. The second is to limit the destination IP address, while the source IP address is arbitrary and is represented by (any, dip,0, count) dip ) Forming a set B (second set); wherein, count dip Indicating the number of the destination IP addresses, if dip is the network segment, count dip Is equal toThe number of IP addresses of each network segment, if dip is a single IP address, count dip Is 1. The third is to limit the source IP address and the destination IP address, which is expressed as (sip, dip, count) sip ，count dip ) A set C (third set) is formed.
Then, a set of QoS rules C1 that completely coincides with the source IP address of the set a (i.e., all of C1 are the above-mentioned first QoS rules) is extracted from the set C, and C1 is marked out from the set C. Meanwhile, a set of QoS rules C2 whose IP addresses coincide completely for the purpose of the set B (i.e., the second QoS rules are all described above in C1) is extracted from the set C, and C2 is marked out from the set C.
And dividing the rules in the set A into N first rule sets P1, P2, \ 8230 \ 8230;. PN according to a load balancing principle, dividing each QoS rule in the set C1 into a first rule set Px corresponding to the QoS rule completely coincident with the source IP address of the QoS rule in the set A, and further allocating the N first rule sets to each forwarding core for processing.
And dividing the set B and the completely non-coincident rules in the set C (the set C does not include C1 and C2) to form a set BC '(namely a fourth set), and dividing each rule in the set BC' into M-1 rule sets according to load balancing. Meanwhile, the rule with the overlapped part in the set B and the set C is divided to form a set BC (namely a fifth set), and the BC set forms a QM rule set. Finally, each rule in the set C2 is divided into a rule set Qx corresponding to a QoS rule completely coincident with the destination IP address of the rule in the set B.
