Detailed Description
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 of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a data transmission system 100 according to an embodiment of the present application, where the system includes a service processing device 110 and a service access device 120, the service access device 120 is a network access point NAP, and the service processing device 110 is a network processing point NSPP. The service access device 120 provides a corresponding Network-Network Interface (NNI) on the user side for the user terminal 130, where the NNI may be directly or indirectly connected to the user terminal 130, and the service access device 120 is configured to receive user service data from the Network Interface on the user side connected to the user terminal 130 and send the user service data to the service processing device 110. The service processing device 110 is configured to receive user service data sent by the service access device 120 or the directly connected user terminal 130, perform corresponding processing on the user service data, and then forward the user service data.
The data transmission system 100 may further include a controller, where the controller may be configured to allocate a corresponding service processing device 110 to each service access device 120, and of course, the controller may also issue a corresponding forwarding table to the service processing device 110 according to a requirement, so that the service processing device 110 may forward the user service data according to the corresponding forwarding table.
However, the inventor finds in research that, in order to implement centralized management on user service data, in the prior art, all service data flows received by the service access device 120 need to be uploaded to the service processing device 110 for related processing, for example, according to service data characteristics and service data processing logic requirements, security filtering, data encryption and decryption, two-layer switching, three-layer routing forwarding, and the like are performed on the service data. However, the service data interacted between two user terminals 130 of the same service access device 120 is also forwarded through the service processing device 110, that is, the service data traffic forwarded between two user-side network interfaces of the service access device 120 is also centrally processed by the service processing device 110, so that processing pressure is applied to the service processing device 110, and consumption of a link bandwidth between the service access device 120 and the service processing device 110 is large.
The above prior art solutions have shortcomings which are the results of practical and careful study of the inventor, and therefore, the discovery process of the above problems and the solutions proposed by the following embodiments of the present invention to the above problems should be the contribution of the inventor to the present invention in the course of the present invention.
Therefore, the embodiment of the present application provides a flow table issuing method, where a forwarding flow table in a service processing device, which is used for forwarding service data on the same service access device, is issued to the service access device, so that the service access device forwards the locally forwarded service data without forwarding the locally forwarded service data through the service processing device, thereby reducing processing pressure of the service processing device, and reducing data interaction between the service processing device and the service access device, so that link bandwidth consumption is correspondingly reduced.
Referring to fig. 2, fig. 2 is a flowchart of a flow table issuing method according to an embodiment of the present application, where the method is applied to a service processing device, and includes the following steps:
step S110: determining a target forwarding flow table of a plurality of forwarding flow tables in the traffic processing device.
The service processing device stores forwarding flow tables for data forwarding among all the user terminals, and the forwarding flow tables are used for realizing addressing forwarding among all the user terminals in the data transmission system. The forwarding flow table records path information identifying data forwarding, which includes an active address, a destination address, a source interface, a destination interface, and a flow counter, and for example, for a certain data flow, the forwarding flow table is in the form of: { incoming interface, source IP address, destination IP address, outgoing interface, counter, next hop MAC address }.
The service processing device needs to issue a target forwarding flow table to the service access device, where forwarding identification information for forwarding the service data traffic originating from the target service access device is recorded in the target forwarding flow table, where the forwarding identification information can be understood as information for identifying that the service data traffic is transmitted from the target service access device to the service processing device, and then the service processing device needs to send the service data traffic to the target service access device for forwarding.
The forwarding flow table in the service processing device may be obtained by the service processing device through address learning, or obtained by issuing by the controller, and after the service processing device obtains the forwarding flow table, the service processing device searches the target forwarding flow table meeting the corresponding conditions from the forwarding flow tables.
For example, the service processing device may complete the configuration of the virtual interface of each user-side network interface on the service access device in advance, such as forming a virtual interface gigabit ethernet-1.1 corresponding to the user-side network interface gigabit ethernet-1 of the service access device 1 and a virtual interface gigabit ethernet-1.2 corresponding to the user-side network interface gigabit ethernet-2 of the service access device 1 on the service processing device, where the former number "1" represents the globally unique index value (i.e. the identifier of the service access device) corresponding to the service access device, and the latter number "1, 2" represents the index value of the user-side network interface inside the service access device.
For example, when the user terminals correspondingly connected to the two user side network interfaces perform message interaction for the first time, the service processing device obtains forwarding path information of its message through learning, and then creates two corresponding forwarding flow tables, which are shown as follows:
{gigabitethernet1.1、128.255.0.10、129.255.0.10、gigabitethernet1.2、00:01:7b:00:00:02、postCounter、currentCounter}；
{gigabitethernet1.2、129.255.0.10、128.255.0.10、gigabitethernet1.1、00:01:7b:00:00:01、postCounter、currentCounter}；
the currentCounter is used for recording the accumulated flow of the service data flow forwarded by the forwarding flow table, the postCounter is used for recording the flow of the service data flow forwarded by the forwarding flow table recorded last time, and the initialization of the two counters is 0.
As an embodiment, the forwarding identification information may include a source interface (i.e. an ingress interface in the forwarding flow table example) and a destination interface (i.e. an egress interface in the forwarding flow table example) of the service data traffic, where the source interface refers to a user-side network interface on the service access device for receiving the service data traffic sent by the user terminal, and the egress interface refers to a user-side network interface on the service access device for forwarding the service data traffic to another user terminal. When the service processing device determines a target forwarding flow table, it may determine a source interface and a destination interface recorded in each forwarding flow table in multiple forwarding flow tables in the service processing device, and if it is determined that the source interface and the destination interface recorded in a forwarding flow table belong to the same service access device, it determines that the forwarding flow table is the target forwarding flow table, that is, it indicates that the target forwarding flow table meets an issuing condition.
For example, if the service processing device finds that a source interface recorded in a certain forwarding flow table is gigabit ethernet1.1 and a destination interface is gigabit ethernet1.2, where "1" may be understood as an identifier indicating a service access device, and thus, it may be determined that the source interface and the destination interface belong to the same service access device, that is, the forwarding flow table is a target forwarding flow table, and the service processing device may issue the forwarding flow table to the service access device identified as 1.
It should be noted that the forwarding identifier information does not only refer to a source interface and a destination interface of the service data traffic, and may be determined according to information recorded in a forwarding flow table in an actual situation, where if only identifiers of the source service access device and the destination service access device are recorded in the forwarding flow table, the two pieces of information may also be used as the forwarding identifier information, and if the identifiers of the source service access device and the destination service access device are the same, it indicates that the forwarding flow table is used to forward the service data traffic from the same service access device. Therefore, it can be understood that the forwarding identifier information recorded in the forwarding flow table for forwarding the service data traffic originating from one service access device from the same service access device may be different according to different actual configuration information for the forwarding flow table.
Step S120: and issuing the target forwarding flow table to the target service access equipment so that the target service access equipment forwards the service data traffic matched with the target forwarding flow table by using the target forwarding flow table.
After determining the target forwarding flow table to be issued, the service processing device may issue the target forwarding flow table to the target service access device. After the service processing device issues the target forwarding flow table to the target access device, the target forwarding flow table may be deleted in order to reduce the table lookup data amount during data forwarding, and certainly, the target forwarding flow table may also be saved in order to facilitate subsequent service data processing of the service processing device on the target forwarding flow table.
In the process that the service processing device issues the target forwarding flow table to the target service access device, the service processing device may send the target forwarding flow table to the target service access device in a message manner, that is, the service processing device may issue the target forwarding flow table to the target service access device through the corresponding message communication component.
The method comprises the steps that after a target service access device receives a target forwarding flow table, the target forwarding flow table is installed, when service data flow is subsequently received, whether a forwarding flow table matched with the service data flow exists in the forwarding flow table stored locally is searched, if yes, the service data flow is forwarded from an outlet interface of the device according to outlet interface information recorded in the corresponding forwarding flow table, if not, the service data flow is transmitted to a service processing device, and the service processing device completes forwarding of the service data flow.
In the implementation process, the forwarding flow table in the service processing device, which is used for forwarding the service data on the same service access device, is issued to the service access device, so that the service access device forwards the locally forwarded service data without forwarding through the service processing device, and thus the processing pressure of the service processing device can be reduced.
In the above embodiment, in order to reduce the processing pressure of the service processing device, the forwarding flow table meeting the condition is issued to the corresponding service access device, but in the actual application process, all the service data flows need to be subjected to centralized processing by the service processing device and then forwarded, in this case, if the service processing device needs to issue all the target forwarding flow tables marked with the above condition (that is, the service processing device needs to issue all the target forwarding flow tables regardless of the condition), the service processing device cannot acquire the part of the service data flows, so that the part of the service data flows cannot be processed correspondingly. However, if the service processing device has sufficient processing capability to process the part of the data traffic, the service processing device may issue the forwarding flow table to the service access device and cannot receive the part of the data traffic, so the service processing device may also select whether to issue the target forwarding flow table according to its own requirement, where the issue conditions include the following conditions:
the first condition is as follows: and acquiring the flow size of the service data flow forwarded by the service processing equipment by using the target forwarding flow table, and issuing the target forwarding flow table to the target access equipment if the flow size exceeds a preset value.
The service processing device may create a forwarding table detection task when being started, where the forwarding table detection task is used to detect, in real time or periodically, a traffic volume of the service data traffic forwarded by each forwarding flow table in the service processing device, for example, when it is detected that the traffic volume of the service data traffic forwarded by a certain forwarding flow table exceeds a preset value within a period of time, and the forwarding flow table is used to forward a local traffic of a service access device, that is, the forwarding flow table records forwarding identification information for forwarding the service data traffic originating from the target service access device, it indicates that the forwarding flow table meets an issuing condition, and then the forwarding flow table may be issued to the target service access device.
For example, the service processing device traverses each forwarding flow table, obtains the flow size of the service data traffic forwarded by the forwarding flow table recorded by the currentcounter from each forwarding flow table, then compares the value with a preset value, and if the value is greater than the preset value and the incoming interface and the outgoing interface recorded in the forwarding flow table belong to the same service access device, issues the forwarding flow table to the service access device.
That is to say, the service processing device may monitor the flow size forwarded by each target forwarding flow table after determining the target forwarding flow table, and only issue the target forwarding flow table when the flow size exceeds a preset value, instead of issuing all the target forwarding flow tables, so as to determine whether to issue the target forwarding flow table according to the flow size, so that when the flow is large, the target forwarding flow table is issued to reduce the data processing pressure of the service processing device, and when the flow is small, the target forwarding flow table is not issued, which is more flexible.
Case two: and acquiring the processing load of the service processing equipment, and if the processing load exceeds a preset value, issuing the target forwarding flow table to the target service access equipment.
The processing load refers to a CPU utilization rate in the service processing device, and if the current CPU utilization rate of the service processing device is large, if a large amount of service data traffic needs to be processed at this time, a large processing pressure may be applied to the CPU, and at this time, the target forwarding flow table may be issued to the service access device when the CPU utilization rate exceeds a preset value.
For example, if the CPU utilization rate in the service processing device is 70% and the preset value thereof is set to 60%, at this time, if the CPU utilization rate exceeds the preset value, the target forwarding flow table in which the ingress interface and the egress interface belong to the same service access device may be recorded, and issued to the corresponding service access device.
In the implementation process, whether the target forwarding flow table is issued can be determined according to the processing load of the service processing device, so that when the processing load is large, the target forwarding flow table is issued to reduce the data processing pressure of the service processing device.
Case three: and acquiring the service data type of the service data flow forwarded by the service processing equipment by using the target forwarding flow table, and issuing the target forwarding flow table to the target service access equipment if the service data type is a preset type.
The service processing device may further determine whether to issue the forwarding flow table to the service access device according to different service data types of the service data traffic forwarded by the forwarding flow table, for example, the forwarding flow table corresponding to the service data type may be flexibly selected according to actual requirements to issue to the service access device, for example, the set service data land corresponding to the service data type includes at least one of Internet Protocol (IP) service data, Multi-Protocol label Switching (MPLS) service data, and Voice Over Internet Protocol (VOIP) service data.
Although the data flow of the VOIP service data is small, the user is sensitive to the time delay, and if the VOIP service data is not forwarded in time, the user experience may be poor, so the forwarding flow table corresponding to the service data type may be issued to the corresponding service access device, and of course, the forwarding flow table also needs to record forwarding identification information that the incoming interface and the outgoing interface belong to the same service access device (that is, the forwarding flow table is the determined target forwarding flow table). Therefore, the corresponding service data flow can be directly forwarded by the service access equipment through the forwarding flow table without forwarding through the service processing equipment, so that the forwarding time can be saved, and the processing pressure of the service processing equipment is also reduced.
In the implementation process, whether the target forwarding flow table is issued or not can be determined according to the service data type, so that the data processing pressure of the service processing equipment is reduced.
In addition, the condition that the service processing device selects the corresponding target forwarding flow table to issue to the target service access device further includes:
case four: the method comprises the steps of obtaining the average flow of service data flow forwarded by a service processing device by using a target forwarding flow table and the processing load of the service processing device in a preset time period, then calculating and obtaining a numerical value for representing whether the target forwarding flow table is issued to a target service access device or not based on the average flow and the processing load, and issuing the target forwarding flow table to the target service access device when the numerical value meets a preset condition.
The traffic detection module arranged in the service processing device may detect each forwarding flow table periodically, or detect each target forwarding flow table, and if the detection is performed every 5 seconds, the average traffic may be obtained by dividing a difference obtained by subtracting a postCounter value from a currentCounter value recorded in the forwarding flow table by 5 seconds.
Then, a first value obtained by performing a square operation on a value corresponding to the processing load is multiplied by the average flow to obtain a second value, and a value obtained by subtracting a preset value from the second value is used as a numerical value for representing whether to issue the target forwarding flow table to the target service access device, wherein a calculation formula can be as follows:
z＝x2×y-10kbps；
wherein z is a numerical value representing whether the target forwarding flow table is issued to the target service access device, x represents the processing load of the service processing device, y represents the average flow, and 10kbps is a preset value.
After z is obtained through calculation, whether z meets a preset condition can be judged, wherein the preset condition can be that when z is larger than 0, a target forwarding flow table is issued to the target service access equipment, and when z is smaller than or equal to 0, the target forwarding flow table is not issued.
In the implementation process, whether the target forwarding flow table is issued or not is comprehensively considered according to the processing load and the average flow of the service processing equipment, and whether the target forwarding flow table is issued or not is judged according to the processing pressure of the service processing equipment.
The service access device deletes the obtained forwarding flow table when a certain condition is met, and continues to forward the service data flow by the service processing device. If the service access device deletes the target forwarding flow table when detecting that the average flow of the service data flow forwarded by using the target forwarding flow table is smaller than the preset value, a notification message can be sent to the service processing device, and the service processing device can know that the target forwarding flow table is deleted by the target service access device after receiving the notification message, and then the service processing device can restart the target forwarding flow table to continue data forwarding.
It can be understood that the service access device runs a monitoring task for detecting the average flow forwarded by each forwarding flow table, and when it is determined that the average flow drops to a value that does not cause the processing pressure of the service processing device and the bandwidth pressure between the service access device and the service processing device, deletes the forwarding flow table, and sends a notification message to the service processing device, where the notification message may carry the accumulated forwarding flow recorded in the forwarding flow table, that is, the value recorded in the currentcounter in the forwarding flow table.
This is explained in detail below with a specific embodiment.
As shown in fig. 3, in the time period between t1 and t2, the traffic size between the user terminal 1 and the user terminal 2 is about 100bps, and both the user terminal 1 and the user terminal 2 are connected to the same service access device, for example, if the forwarding flow table 1 is used for forwarding the service data traffic between the user terminal 1 and the user terminal 2, at this time, according to the situation described in the fourth case, the corresponding forwarding flow table 1 does not satisfy the issuing condition, and then does not issue.
At time t2, when the user terminal 1 sends video traffic to the user terminal 2, the size of the video traffic is 10Mbps, and assuming that the CPU utilization of the service processing device is 70% at this time, according to the situation described in the above fourth scenario, when the forwarding flow table 1 meets the issuing condition, the forwarding flow table 1 is issued to the corresponding service access device.
After the service processing device issues the forwarding flow table 1, the values recorded by postCounter and currentCounter in the forwarding flow table 1 may be cleared.
The service access device receives the forwarding flow table 1 and installs the forwarding flow table 1 to the local forwarding flow table component, so that the traffic sent by the user terminal 1 to the user terminal 2 can be locally forwarded in the service access device according to the forwarding flow table 1.
At time t3, the user terminal 1 stops sending video traffic to the user terminal 2, and only 100bps traffic remains between the user terminal 1 and the user terminal 2, at this time, the service access device detects that its average traffic is reduced, and if the average traffic is smaller than the preset value of 2kbps, deletes the forwarding flow table 1, and then sends a corresponding notification message to the service processing device to notify the service processing device that the forwarding flow table 1 has been deleted.
Then, after receiving the notification message, the service processing device obtains the cumulative flow recorded by the currnet counter in the forwarding flow table 1 from the notification message, and then updates the cumulative flow to the currnet counter in the forwarding flow table 1 stored locally.
It should be noted that, in the process of determining whether to issue the corresponding target forwarding flow table to the target service access device, the service processing device may select any one of the four situations to further determine whether to issue, may also select any two, three, or four situations to comprehensively determine whether to issue, and may flexibly select according to actual requirements.

step S210: and receiving service data flow from the first interface of the service access equipment.
Step S220: and searching corresponding forwarding identification information from a pre-stored target forwarding flow table according to the forwarding information carried in the service data flow.
The target forwarding flow table records forwarding identification information for forwarding the service data traffic received from the first interface of the service access device from the second interface of the service access device. The target forwarding flow table may be a forwarding flow table generated locally by the service access device, or may also be a pre-configured forwarding flow table, where the target forwarding flow table is as shown in the foregoing embodiment, and is used to implement forwarding of data traffic inside the service access device.
As an implementation manner, the target forwarding flow table may also be issued by the service processing device, that is, the target forwarding flow table is issued to the service access device when the service processing device detects that forwarding identification information for forwarding the service data traffic originating from the service access device is recorded in the target forwarding flow table. For the implementation process of issuing the target forwarding flow table by the service processing device, please refer to the related description of the above embodiment, which is not described herein in detail.
Step S230: and forwarding the service data flow from the second interface according to the forwarding identification information.
The service access device can directly forward the service data traffic through the second interface of the local terminal, so as to realize the forwarding of the data traffic inside the device.
In the implementation process, the service access device forwards the locally forwarded service data without forwarding the service data through the service processing device, so that the processing pressure of the service processing device can be reduced.
