Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. 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 application.
Referring to fig. 1, fig. 1 is a flowchart of an interface speed limiting method according to an embodiment of the present disclosure. The method comprises the following steps:
s101: and if the data traffic is detected from the data interface, extracting the speed limit information corresponding to the data traffic.
Some or all of the steps in this embodiment may be executed by an interface speed limiting device, where the interface speed limiting device may be a device that performs data traffic transmission, and may be, for example, a firewall, a router, a virtual machine, a DHCP (Dynamic Host Configuration Protocol) server, and the like. The data interface may be a virtual interface or an entity interface, and the specific content and type of the data traffic are not limited, and may be data traffic in any form and using any data protocol. The embodiment does not limit the specific manner of detecting the data traffic, for example, the data interface may be monitored, and the data traffic is determined to be detected after the data traffic is monitored; or other detection means may be used to detect the data interface.
The speed limit information can indicate the identity of the data flow, and then the speed limit information is used for matching detection with the DPI rule to realize speed limit processing of the data flow. The speed limit information may specifically include source information and destination information, where the source information is used to indicate a source location of the data traffic (i.e., a source device, a source network, etc.), and the destination information is used to indicate a destination location of the data (a destination device, a destination network, etc.). By the source and destination of the data traffic, the identity of the data traffic can be determined, and the data traffic in the data flow direction (i.e. the direction from the source location to the destination location) or in the data link bi-directional direction (i.e. the direction from the source location to the destination location and the direction from the destination location to the source location) can be rate-limited if necessary. The source information may include a source IP address, a source port number, etc., and the destination information may include a destination IP address, a destination port number, etc.
In a specific embodiment, in order to further improve the flexibility of speed limit, a four-layer protocol number may be further included in the speed limit information. Extracting speed limit information corresponding to data flow, comprising:
step 11: and extracting a destination IP address, a source IP address, a destination port number, a source port number and a four-layer protocol number corresponding to the data traffic as speed limit information.
It should be noted that, in order to perform speed limiting more finely, the protocol number should be a four-layer protocol number. The four-layer protocol number refers to a protocol number corresponding to a TCP/IP four-layer structure (network interface layer-internet layer-transport layer-application layer). Data traffic of different purposes needs to be distinguished on an application layer, and data traffic of different purposes may need to be subjected to different speed limiting processing. Real-time data such as real-time call data and video data need to be transmitted as soon as possible, while non-real-time data such as a transmission file need not be transmitted as soon as possible. Therefore, the data traffic identity can be determined through the protocol number of the application layer only when the acquired protocol number is the four-layer protocol number.
S102: and matching and detecting the speed limit information and the DPI rule corresponding to the data interface.
Dpi (deep Packet inspection) is a Packet-based deep inspection technology, which can perform filtering control on inspection traffic according to a predefined policy by inspecting and analyzing the traffic and Packet content at key points of a network. The DPI rule in this embodiment is a policy defined in advance for performing rate-limiting processing on data traffic, and the specific form thereof is not limited. The DPI rule corresponds the speed limit information with the corresponding bandwidth, namely records the corresponding relation between the speed limit information and the bandwidth. The number of the DPI rules is multiple, and each DPI rule can record the corresponding relation between different speed limit information and different bandwidths or record the corresponding relation between the same speed limit information and different bandwidths.
After the speed limit information is obtained, matching detection is performed on the speed limit information and the DPI rule corresponding to the data interface, it should be noted that the DPI rule corresponding to the data interface may be all or part of the DPI rules, that is, not every interface corresponds to all the DPI rules. In a feasible implementation manner, corresponding DPI rules can be allocated to different interfaces according to actual needs, so that when different data interfaces acquire the same data traffic, different speed-limiting processing can be performed on the data traffic according to corresponding different DPI rules. When the speed limit information is matched with the DPI rule, a target DPI rule passing through the matching detection may exist, or any DPI rule not matched with the speed limit information may exist.
The present embodiment does not limit the specific obtaining manner of the DPI rule, for example, in a feasible implementation, the DPI rule may be input by a user, for example, the DPI rule may be obtained by parsing the rule file; or rule information can be input, and the DPI rule is generated according to the input rule information. In another possible implementation, DPI rules sent by other terminals or devices may be received, for example, DPI rules sent by other interface rate limiting devices may be received. After the DPI rule is obtained, a corresponding DPI rule needs to be specified for the data interface. In a possible implementation manner, DPI rule information may be added to the configuration information for configuring the interface speed limiting device, so as to configure the speed limiting function (belonging to the QOS function) at the same time when the interface speed limiting device is configured, without separately configuring the speed limiting function for the interface speed limiting device. Specifically, the method may further include:
step 21: and acquiring and analyzing the configuration information to obtain DPI rule information.
Step 22: and binding each data interface with the corresponding DPI rule according to the DPI rule information.
The present embodiment does not limit the specific form of the DPI rule information, and may be, for example, an array form, where a first element of the array is used to specify a data interface, and may be, for example, a serial number of the data interface; other elements of the array may be used to specify DPI rules, and each element may specify one or a set of DPI rules. And after the DPI rule corresponding to each data interface is determined, binding the data interface with the DPI rule. Each data interface may bind to multiple DPI rules, and correspondingly, each DPI rule may bind to multiple data interfaces.
Further, the DPI rule may be adjusted, for example, the DPI rule may be added, deleted, or modified. Specifically, the method may further include:
step 31: if the rule adjusting instruction is obtained, adjusting the DPI rule according to the instruction; the rule adjusting instruction is a rule adding instruction, a rule modifying instruction or a rule deleting instruction
The rule adjusting instruction may be a rule adding instruction, a rule modifying instruction or a rule deleting instruction. The rule adding instruction is used for adding a DPI rule, or can be used for adding a corresponding relation between one or more DPI rules and one or more data interfaces. The rule modification instructions may be used to modify the content of the DPI rule, e.g., may modify a bandwidth value in the DPI rule. The rule deletion instruction may be used to delete one or more DPI rules or may be used to delete a correspondence between one or more DPI rules and one or more data interfaces. It should be noted that step 31 may be performed at any time after the DPI rule is acquired, and is not a necessary step, i.e., the present embodiment does not limit whether step 31 is necessarily performed.
It should be noted that, since the source information and the destination information in the speed limit information can describe the identity of the data traffic, correspondingly, the DPI rule can also perform the speed limit function by recording the source information and the destination information, that is, a group of source information and destination information is combined with a certain bandwidth value, and after the data traffic with the group of source information and destination information is detected, the speed limit processing is performed on the data traffic according to the corresponding bandwidth value. Based on this, in a possible implementation manner, a bi-directional speed limit can be performed by using one DPI rule, that is, the speed limit is performed on both the data traffic in the direction from the source location to the destination location and the data traffic in the direction from the destination location to the source location by using corresponding bandwidth values. The S102 step may include:
step 41: and judging whether a first DPI rule which takes the destination IP address and the destination port number as destination information and takes the source IP address and the source port number as source information exists.
Step 42: and if the first DPI rule exists, performing matching detection by using the first DPI rule and the four-layer protocol number.
Step 43: if the first DPI rule does not exist, whether a second DPI rule which takes the source IP address and the source port number as destination information and takes the destination IP address and the destination port number as source information exists is judged.
Step 44: and if the second DPI rule exists, performing matching detection by using the second DPI rule and the four-layer protocol number.
When performing the matching detection, it may be determined whether a forward first DPI rule exists, that is, whether a first DPI rule exists that uses a destination IP address and a destination port number as destination information and uses a source IP address and a source port number as source information. If the data flow is matched with the four-layer protocol number, the first DPI rule is the target DPI rule. If the first DPI rule does not match the four-layer protocol number, step 43 may be performed for bi-directional inspection. If the first DPI rule does not exist, whether a second DPI rule exists is judged, namely whether the second DPI rule which takes the source IP address and the source port number as destination information and takes the destination IP address and the destination port number as source information exists is judged. If the first DPI rule exists, the second DPI rule and the four-layer protocol number are used for matching detection, namely, the steps corresponding to the case that the first DPI rule exists are executed, and the difference is that the first DPI rule is replaced by the second DPI rule. If the second DPI rule does not exist, it may be determined that there is no target DPI rule detected by the match. By using the technical scheme from step 41 to step 44, only one DPI rule can be used for bidirectional matching detection, thereby reducing the number of required DPI rules.
S103: and if the target DPI rule passing the matching detection exists, carrying out speed limiting treatment on the data flow according to the target bandwidth corresponding to the target DPI rule.
And if the target DPI rule passing the matching detection exists, the data flow needs to be subjected to speed limiting processing. And determining a corresponding target bandwidth by using a target DPI rule, and carrying out speed-limiting treatment on the data flow according to the target bandwidth. The present embodiment does not limit the specific size of the target bandwidth, and may be any non-negative number. It should be noted that the target bandwidth may be zero, in which case the data traffic may be blocked. The S103 step may include:
step 51: and if the target bandwidth is zero, discarding the data traffic.
Step 52: and if the target bandwidth is not zero, transmitting the data traffic according to the target bandwidth.
If the target bandwidth is zero, it indicates that the data traffic is not transmitted, and therefore the data traffic to be discarded. If the target bandwidth is not zero, it indicates that the data traffic needs to be rate-limited, so the data traffic is transmitted according to the target bandwidth.
In one embodiment, there may be no target DPI rule detected by matching, in which case, it may further include:
step 61: and if the target DPI rule which passes the matching detection does not exist, transmitting the data flow according to the maximum available bandwidth.
If the target DPI rule which passes the matching detection does not exist, the data traffic does not need to be subjected to speed limiting processing, so that the data traffic is transmitted according to the maximum available bandwidth, namely, the data traffic is transmitted in a best effort mode.
By applying the interface speed limiting method provided by the embodiment of the application, different data flows are processed differently by using the DPI rules, after the data flow is detected at a certain data fracture, whether the speed limiting processing is needed or not is judged by using the speed limiting information corresponding to the data flow, if the DPI rule corresponding to the data interface has the target DPI rule corresponding to the speed limiting information, the data flow needs to be subjected to the speed limiting processing, and therefore the data flow is subjected to the speed limiting processing according to the target bandwidth corresponding to the target DPI rule. The DPI rule is set for the data interface, and different bandwidth constraints are set for different data flows, so that different speed-limiting processing can be performed on different data flows passing through the same data interface, a complex network application scene can be adapted, all flows passing through the data interface are not processed according to the same bandwidth constraints, the flexibility degree of interface speed limitation is improved, and the requirement of complex business is met. The problem that the interface speed limit of the related technology is not flexible enough, cannot cope with complex network application scenes, and cannot meet the requirements of current services is solved.
Referring to fig. 2, fig. 2 is a flowchart of a specific interface speed limiting method according to an embodiment of the present application. In this embodiment, a QOS service segment is used to configure a QOS function in an Openstack deployed multi-architecture cluster environment. The QOS service end is specifically a QOS service configuration of a Neutron Server, and issues/updates a deep packet processing rule (i.e. a DPI rule) based on network flow data content, so that the DPI rule is applied to each virtual port of network transmission equipment (i.e. interface speed limiting equipment), such as virtual interfaces of DHCP, firewall, router, virtual machine and the like. The specific process is as follows:
1: a QOS service module of a control node where a Neutron Server is located issues a DPI rule to a virtual interface needing speed limiting (namely binding a data interface and the DPI rule), wherein the rule content comprises Key and a matching result; the Key contains a source and destination IP address (a source IP address and a destination IP address), a source and destination port number (a source port number and a destination port number), a four-layer protocol number, and a matching result of the rule is a speed limit peak value of the bandwidth.
2: after the network traffic (i.e. data traffic) enters the virtual interface, the QOS service module extracts the source and destination IP of the traffic, the source and destination port number, and the protocol type of the fourth layer protocol of the packet, to form a key (i.e. speed limit information) for rule matching.
3: and performing matching query operation of the DPI rule table according to the input Key.
4: according to the query result of the DPI rule table, if a certain DPI rule in the DPI rule table is hit, the data flow of the hit rule passing through the virtual interface is limited by the set bandwidth peak value according to the bandwidth peak value set in the rule hit result, and if the bandwidth of the hit result is distributed to be 0, the data flow of the hit rule is forbidden to pass through and is directly discarded at the port.
5: according to the query result of the DPI rule table, if the rule of the DPI rule table is missed, all traffic of the virtual interface will be transmitted in a "best effort" manner, i.e. data transmission is performed using the maximum available bandwidth.
6: the QOS service module may delete the DPI rule issued to the virtual interface, and at this time, it may be observed that the corresponding data traffic passing through the virtual interface is not limited by speed, and the data traffic is transmitted in a "best effort" manner at the virtual interface. That is, if the DPI rule is issued/updated to the virtual interface, the traffic normally passes.
