Description

Method for updating model and related device

Technical Field

The present application relates to the field of communications, and more particularly, to a method and related apparatus for model update.

Background

With the continuous development of intelligent terminals, explosive growth of applications is brought, so that interactive messages between the applications and the server are complex, and therefore, the requirements of identifying the service types of the messages for further processing and processing are met. For example, for game applications, the requirement for time delay is high, so that after the service type of the message is identified as the game service, service functions such as game acceleration or child internet surfing protection can be realized.

Typically, routers identify the traffic type of a message by an identification model. Each service type corresponds to a service Identification (ID). However, the message characteristics of each service ID may change with the update of its version, and as the update of the version of the application iterates, the recognition accuracy of the old recognition model gradually decreases, so that the recognition model needs to be updated. In the existing scheme for updating the identification model, a developer is required to collect the message and calibrate the sample, so that a great deal of labor cost is brought, and the efficiency of collecting the sample message is low.

Disclosure of Invention

The application provides a method and a related device for updating a model, aiming at improving the efficiency of collecting a sample message.

In a first aspect, a method for updating a model is provided, applied to a routing device, the method comprising: acquiring a first ID and a second ID of a message to be identified; and under the condition that the first ID and the second ID are inconsistent, determining the message to be identified as a sample message, wherein the sample message is used for updating the identification model.

In the application, the routing device can acquire the first ID and the second ID, wherein the first ID is the identification ID obtained by identifying the message to be identified through the identification model, and since the message characteristics of the same service ID may change along with the update of the version of the application, if the identification model is not updated in time, the first ID acquired by the routing device through the identification model may not be the service ID to which the message to be identified really belongs, i.e. the result of identifying the message to be identified through the identification model may be wrong. The second ID is the service ID of the service to which the message to be identified belongs, and is the real service ID of the message to be identified.

When the routing device determines that the first ID and the second ID are inconsistent, the routing device determines that the second ID obtained through the identification model is wrong, and is not the service ID of the service to which the message to be identified belongs, so that the routing device can determine the message to be identified as a sample message, and the server updates the identification model based on the sample message to obtain an updated identification model. Therefore, the routing equipment can automatically collect the sample message of the calibrated service ID without manually collecting the sample message and calibrating the version message, thereby being beneficial to saving manpower and time cost, improving the efficiency of collecting the sample message and further improving the efficiency of updating the identification model.

It will be appreciated that the application is exemplified by messages transmitted over a transmission control protocol (transmission control protocol, TCP) connection or a user datagram protocol (user datagram protocol, UDP) connection between the terminal device and the server. The messages transmitted over the one TCP connection or UDP connection have the same five-tuple information. For ease of description, a TCP connection or a UDP connection will be hereinafter simply referred to as a connection.

With reference to the first aspect, in some implementations of the first aspect, obtaining the first ID and the second ID of the message to be identified includes: identifying the message to be identified through an identification model to obtain a first ID; based on the first quintuple information, a corresponding second ID is obtained from pre-stored mapping relation information, the mapping relation information indicates at least one group of corresponding relation among the service ID, the identification ID and the quintuple information, and the first quintuple information is the quintuple information of the message to be identified.

In the application, the routing equipment can acquire the message to be identified based on the routing forwarding protocol, and the message header of the message to be identified comprises the first quintuple information, namely, the routing equipment is the first quintuple information acquired through the routing forwarding protocol. Before the routing device obtains the first ID, mapping relation information indicating the service ID, the identification ID and the quintuple information is pre-stored in the routing device, so that the routing device can obtain the service ID corresponding to the first quintuple information, namely the second ID, from the pre-stored mapping relation information after obtaining the first quintuple information and the first ID. In this way, the routing device can obtain the first ID and the second ID, so as to compare whether the first ID and the second ID are consistent, and determine whether the message to be identified can be used as a sample message.

With reference to the first aspect, in some implementations of the first aspect, before acquiring the corresponding second ID from the pre-stored mapping relationship information based on the first quintuple information, the method further includes: receiving a second ID and second quintuple information from the terminal equipment, wherein the first quintuple information is the same as the second quintuple information; and updating the mapping relation information based on the second ID and the second quintuple information.

Thus, after receiving the first quintuple information, the routing device can obtain the second ID from the updated mapping relationship information based on the first quintuple information.

It should be understood that the routing device may obtain five-tuple information (i.e. the second five-tuple information) and the service ID (i.e. the second ID) of a connection from the first Application (APP) of the terminal device to the server. The first quintuple information indicates quintuple information carried in any message to be identified transmitted from the first APP to the server, and the first quintuple information is the same as the second quintuple information.

With reference to the first aspect, in some implementations of the first aspect, obtaining the first ID and the second ID of the message to be identified includes: receiving second ID and second quintuple information from the terminal equipment, wherein the second quintuple information is the same as the first quintuple information, and the first quintuple information is quintuple information of a message to be identified; based on the second quintuple information, a corresponding first ID is obtained from the pre-stored mapping relation information. Wherein the mapping relation information indicates at least one group of correspondence relation of the service ID, the identification ID and the quintuple information.

In the application, before the routing equipment receives the second quintuple information and the second ID, the routing equipment pre-stores the mapping relation information indicating the service ID, the identification ID and the first quintuple information. After receiving the second quintuple information and the second ID, the routing device may obtain an identification ID corresponding to the second quintuple information from the mapping relationship information, and determine the first ID based on the identification ID, because the first quintuple information and the second quintuple information are the same. In this way, the routing device can obtain the first ID and the second ID, so as to compare whether the first ID and the second ID are consistent, and determine whether the message to be identified can be used as a sample message.

With reference to the first aspect, in certain implementation manners of the first aspect, before acquiring the corresponding first ID from the pre-stored mapping relationship information based on the second quintuple information, the method further includes: receiving a message to be identified, wherein the message to be identified carries first quintuple information, and the first quintuple information is identical to the second quintuple information; identifying the message to be identified through an identification model to obtain a first ID; the mapping relationship information is updated based on the first ID and the first quintuple information.

In the application, the routing equipment receives the message to be identified first, identifies the message to be identified through the identification model to obtain the first ID, and updates the mapping relation information based on the first ID and the first quintuple information. The routing device may then obtain the first ID from the pre-stored updated mapping information.

With reference to the first aspect, in some implementations of the first aspect, the second ID is carried in a message to be identified. The method for acquiring the first ID and the second ID of the message to be identified comprises the following steps: acquiring a second ID from a message to be identified; and identifying the message to be identified through the identification model to obtain a first ID.

In the application, the message to be identified received by the routing equipment comprises the second ID, and the routing equipment can identify the message to be identified through the identification model to obtain the first ID. In this way, the routing device can obtain the first ID and the second ID, so as to compare whether the first ID and the second ID are consistent, and determine whether the message to be identified can be used as a sample message.

With reference to the first aspect, in certain implementations of the first aspect, the method further includes: and storing mapping relation information, wherein the mapping relation information indicates the corresponding relation of the first ID, the second ID and first quintuple information, and the first quintuple information is quintuple information of the message to be identified.

With reference to the first aspect, in some implementations of the first aspect, the mapping relationship information is stored in a hash bucket with the first quintuple information as a key and the service ID and the identification ID as values.

In the application, the first ID and/or the second ID can be rapidly queried by storing the mapping relation information in the hash bucket, which is beneficial to improving the data query rate.

With reference to the first aspect, in certain implementation manners of the first aspect, after determining that the message to be identified is a sample message, the method further includes: the payload of the sample message and the second ID are sent to the server.

In the application, after determining the sample message, the routing device may send the payload of the sample message and the label of the sample message, that is, the second ID, to the server, so that the server updates the identification model based on the sample message. Thus, the routing equipment automatically completes the collection and calibration of the sample message, which is beneficial to improving the efficiency of collecting the sample message and further improving the efficiency of updating the identification model.

In the application, the terminal equipment can acquire the service ID of the newly added connection and five-tuple information required by the transmission of the message on the newly added connection when sensing the newly added non-local connection. The destination address of the non-local connection is a wide area network address, and may be understood as an item of an external network server (non-class C address).

The terminal equipment can send the service ID and the quintuple information to the routing equipment, so that the service ID of the service to which the message transmitted on the newly added connection belongs is favorably provided for the routing equipment, the efficiency of collecting the sample message is further improved, and the service identification optimization function of the terminal equipment is enhanced.

The technical scheme of the application will be described below with reference to the accompanying drawings.

In order to clearly describe the technical solution of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same item or similar items having substantially the same function and effect. For example, the first ID and the second ID are for distinguishing different IDs, and the order of the different IDs is not limited. It will be appreciated by those of skill in the art that the words "first," "second," and the like do not limit the amount and order of execution, and that the words "first," "second," and the like do not necessarily differ.

In the present application, the words "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

Furthermore, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, and c may represent: a, b, or c, or a and b, or a and c, or b and c, or a, b and c, wherein a, b and c can be single or multiple.

Currently, the routing equipment can intelligently identify the service type of a message through a service awareness (service awareness, SA) module in a kernel protocol stack, so that the service functions of accelerating game, protecting children from surfing the internet, and the like are realized, and the user experience is improved. Wherein, the recognition needs to be completed by relying on a knowledge base, which is called a recognition model in the embodiment of the application.

Since the message characteristics of the message may change as the APP version is updated, the identification ID obtained through the identification model may not be consistent with the service ID. Under the condition that the service ID and the identification ID are inconsistent, the routing equipment can determine that the message to be identified is a sample message and send the sample message to the server. The server updates the identification model based on the sample message, so that the updated identification model can be obtained, the labor and time cost for manually collecting the sample message can be saved, and the efficiency for collecting the sample message can be improved.

Fig. 1 is a schematic diagram of a communication scenario 100 to which embodiments of the present application are applicable. The communication scenario 100 shows a routing device 01, a server 02 and a terminal device 03.

The terminal device 03 is a down-hanging device of the routing device 02, and the terminal device 03 can access the routing device 01 to access the network, and request network services from the server 02 through the routing device 01.

The routing device 01 may be any device with routing forwarding, message processing capabilities, such as a router.

The server 02 is a server that establishes a TCP/UDP connection with an application in the terminal device, for example,is->Is a server of (a). When the user opens at the terminal 03 +.>Terminal 03 anda connection is established between servers.

The embodiment of the present application takes as an example the transmission of a message on a connection (TCP connection or UDP connection) between the terminal device 03 and the server 01. The messages transmitted over the one connection have the same five-tuple information, and the messages transmitted over the one connection belong to the same service type, i.e. the messages transmitted over the one connection have the same service ID.

FIG. 2 is a schematic flow chart of a method 200 for model update provided by an embodiment of the present application. The method 200 may be applied to the communication scenario 100 as shown in fig. 1, but embodiments of the present application are not limited thereto. The steps of the method 200 may be performed by a routing device, the method 200 comprising the steps of:

s201, acquiring a first ID and a second ID of a message to be identified;

s202, under the condition that the first ID and the second ID are inconsistent, determining the message to be identified as a sample message, wherein the sample message is used for updating the identification model.

In the embodiment of the application, the first ID is an identification ID obtained by identifying the message to be identified through the identification model, and the second ID is a service ID of a service to which the message to be identified belongs.

Since the message characteristics of the message may change with the update of the APP version, if the identification model is not updated in time, the first ID obtained by the identification model may not be the true service ID of the message to be identified. Therefore, the routing device can acquire the first ID and the second ID, compare the first ID with the second ID, and determine that the message to be identified is a sample message under the condition that the first ID and the second ID are inconsistent. Thus, the routing equipment automatically completes the collection of the sample message and the label (namely the second ID) of the sample message, which is beneficial to saving the manpower and time cost for manually collecting the sample message, improving the efficiency of collecting the sample message and further improving the efficiency of updating the identification model.

By way of example only, and in an illustrative,the routing device is to +.A.A service ID of (1) is 101 by identifying model>The message of (2) is identified to obtain an identification ID of 102, and when the service ID and the identification ID are inconsistent, the routing equipment is used for carrying out +.>Is erroneous, the routing device may send +.>Is sent to +.>Is composed of (1) a server composed ofThe server of (a) updates the identification model.

In the embodiment of the application, the first ID is an identification ID obtained after the routing device receives a message to be identified transmitted on a connection through a routing forwarding protocol, and the routing device identifies the service type of the message to be identified through an identification model. The second ID is a service ID received by the routing device from the terminal device. There are two ways for the routing device to receive the traffic ID: in one mode, the routing device receives a service ID through a private protocol (e.g., a mac-link protocol); and in a second mode, the routing equipment acquires the service ID from the message to be identified received through the routing forwarding protocol, wherein the mode needs to design the message, and the message to be identified carries the service ID.

It should be understood that, for the first mode, the message to be identified that is received by the routing device through the routing forwarding protocol may be a message to be identified from the terminal device, or may be a message to be identified from the server. For the second mode, the message to be identified including the service ID is a message to be identified from the terminal device.

The following describes the specific implementation flow of the method provided by the embodiment of the present application in combination with the two modes respectively.

First, description will be made in connection with mode one:

based on the first mode, the routing device receives a message to be identified through the routing forwarding protocol, and the message to be identified does not comprise a service ID. The routing device receives the traffic ID from the terminal device via a proprietary protocol (e.g., a mac-link protocol). It may also be understood that the routing device receives the message to be identified through a first link, and receives the service ID through a second link, where the first link is a link established by the terminal device and the routing device based on the routing forwarding protocol, and the second link is a link established by the terminal device and the routing device based on the private protocol, and the first link and the second link are different.

In the embodiment of the application, the routing equipment may identify the message to be identified through the identification model to obtain the identification ID, and then receive the service ID based on the private protocol; or the method comprises the steps of receiving the service ID based on the private protocol, and identifying the message to be identified through the identification model to obtain the identification ID.

The following describes the process that the routing device firstly receives the service ID and then identifies the message to be identified through the identification model to obtain the identification ID by combining with the drawing.

FIG. 3 is a schematic flow chart of another method 300 for model update provided by an embodiment of the present application. The method 300 may be applied to the communication scenario 100 shown in fig. 1, but embodiments of the present application are not limited thereto. The method 300 includes steps S301 to S305, which are as follows:

s301, the terminal equipment sends a second ID and second quintuple information to the routing equipment. Accordingly, the routing device receives the second ID and the second quintuple information.

In this step, when the terminal device senses the new connection and the destination address of the new connection is the wide area network address, determining a second ID corresponding to the server and providing second quintuple information of the transmission message of the new connection. After determining the second ID and the second quintuple information, the terminal device and the routing device transmit the second ID and the second quintuple information based on a private protocol.

It should be understood that the second quintuple information is quintuple information of a message transmitted on the newly added connection, and the quintuple information of the message transmitted on the newly added connection is the same as the second quintuple information.

The second quintuple information comprises a source IP address, a source port, a destination IP address, a destination port and a protocol type, wherein the protocol type is TCP or UDP. Illustratively, "0" means UDP and "1" means TCP.

S302, the routing device updates the mapping relation information based on the second ID and the second quintuple information.

Illustratively, the routing device receives the second ID and the second quintuple information serialized into the json format, and the routing device may deserialize the second ID and the second quintuple information in the json format into a structure.

In the embodiment of the application, the routing equipment pre-stores mapping relation information, wherein the mapping relation information comprises at least one group of corresponding relation of service ID, identification ID and quintuple information.

After receiving the second ID and the second quintuple information, the routing device may update the pre-stored mapping relationship information, that is, add a set of service IDs, a correspondence between the identification IDs and the second quintuple information to the pre-stored mapping relationship information.

Fig. 4 is a schematic diagram of a hash bucket according to an embodiment of the present application. The routing device takes the second quintuple information as a key, takes the service ID and the identification ID as values, and adds the corresponding relation of the service ID, the identification ID and the second quintuple information into the hash bucket.

The routing device first determines an index index_1 of a hash bucket for storing the correspondence between the service ID, the identification ID and the second quintuple information, and the calculation formula is as follows:

index_1＝jhash(key_1，len_1，salt)％DM_BUCKET_NUM

Where key_1 represents the second quintuple information, len_1 represents the length of key_1, salt is hash BUCKET salt, random value, dm_buffer_num is the number of hash BUCKETs, and dm_buffer_num=255, for example.

As shown in fig. 4, one hash bucket corresponds to at least one hash chain (hashlist), which is an ordered one-way chain ordered by source ports.

Illustratively, index_1=1, and the routing device may store the correspondence relationship of the service ID, the identification ID, and the second quintuple information in hash bucket No. 1. Two hash chain tables are corresponding in the hash bucket 1, wherein the source port in one hash chain table is 49152, and the source port in the other hash chain table is 49199. For example, the source port in the second quintuple information is 49153, so the routing device may insert a linked list with a source port 49153 between the two hash linked lists, and add a set of service IDs, an identification ID, and a correspondence relationship between the second quintuple information in the linked list with a source port 49153.

Optionally, as shown in fig. 4, the linked list of the source port 49153 further includes a message pointer (pData), where the message pointer points to a successfully identified message to be identified.

As shown in fig. 4, the routing device illustratively assigns a traffic ID of 101, indicating a traffic type of If the routing device identifies a message to be identified on one connection through the identification model, but the message is not identified successfully temporarily, the routing device may assign an identification ID of "-1" in the linked list with a source port 49153, and continue to identify the message to be identified that is received subsequently on the one connection.

Illustratively, the meaning of the identification ID assignment corresponds to: "-1" indicates that the temporary unrecognization was successful; "0" indicates no recognition; a value greater than 0 indicates successful recognition.

Illustratively, the meaning of the business ID assignment corresponds to: "-1" indicates that the terminal device has not reported the service ID; a value greater than 0 indicates a service ID that has been successfully reported.

S303, the routing equipment identifies the message to be identified through the identification model, and a first ID is obtained.

In this step, the message to be identified includes first quintuple information, and the first quintuple information is the same as the second quintuple information. The routing device may identify the first N messages received on a connection, where the first N messages are messages to be identified. Each time the identifications are independent of each other, there is no confidence accumulating effect.

Illustratively, taking fig. 4 as an example, in a case where the routing device does not receive the packet to be identified, the routing device may not assign an ID in the linked list of source ports 49153, or the routing device assigns an ID in the linked list of source ports 49153 to be "-1".

Taking fig. 4 as an example, after receiving a first message to be identified on a connection, the routing device identifies the first message to be identified through an identification model. If the identification is unsuccessful, the routing device updates the identification ID in the linked list with the source port 49153 based on the five-tuple information of the first message to be identified, and assigns the identification ID to be "-1". The routing equipment continues to receive a second message to be identified on the same connection, identifies the second message to be identified through an identification model, and if the identification is successful, the obtained identification ID is a value larger than 0, and the routing equipment determines that the identification ID of the second message to be identified is the second ID. After the identification is successful, the routing equipment does not identify the message on the same connection.

Taking fig. 4 as an example, if the routing device does not successfully identify the first N-1 messages to be identified, when the N-th message to be identified is still not successfully identified, the ID of the identification obtained by the routing device is 0. In this case, the routing device no longer recognizes the messages on the same connection.

In combination with the above examples of successful or unsuccessful recognition, the routing device determines an identification ID greater than or equal to 0 as the first ID.

The above identification ID assignment and service ID assignment are merely examples, and embodiments of the present application are not limited thereto.

S304, the routing equipment acquires a corresponding second ID from the pre-stored mapping relation information based on the first quintuple information. The mapping relation information indicates at least one set of correspondence relation of the service ID, the identification ID and the quintuple information.

In this step, the first quintuple information is quintuple information of the message to be identified. After obtaining the first ID, the routing device uses the first five-tuple information as a key to obtain the second ID from the mapping relation information pre-stored in the hash bucket. The message to be identified here is, for example, a message to be identified successfully in the first N messages to be identified in the above example, or an nth message to be identified in a case that none of the first N messages to be identified is identified successfully.

Illustratively, the routing device first determines index_2 of the hash bucket storing the mapping relationship information, and the calculation formula is as follows:

index_2＝jhash(key_2，len_2，salt)％DM_BUCKET_NUM

where key_2 represents the first quintuple information, len_2 represents the length of key_2, salt is hash BUCKET salt, random value, dm_buffer_num is the number of hash BUCKETs, and dm_buffer_num=255, for example. It should be understood that the routing device may find the hash bucket salt of computing index_1 above, where the hash bucket salt of computing index_1 is the same as the hash bucket salt of computing index_2.

Since the first quintuple information and the second quintuple information are the same, len_1 and len_2 are the same, and thus index_2 obtained by the hash calculation is the same as index_1. In this way, the routing device can find the hash bucket storing the mapping relationship information. Taking fig. 4 as an example, index_1=index_2=1, and the routing device determines that the service ID corresponding to the first five-tuple information is stored in the hash bucket No. 1. Further, the routing device searches the hash bucket No. 1 for a linked list of source ports identical to the source ports in the first five-tuple information, such as the linked list of source ports 49153 in fig. 4. The linked list of the source port 49153 indicates the correspondence between the service ID, the identification ID and the second quintuple information. Because the first quintuple information and the second quintuple information are the same, the corresponding relationship between the service ID, the identification ID and the second quintuple information is the corresponding relationship between the service ID, the identification ID and the first quintuple information. Thus, the routing device acquires the service ID corresponding to the first five-tuple information from the linked list of the source port 49153, and determines the service ID as the second ID.

S305, the routing equipment determines that the message to be identified is a sample message under the condition that the first ID and the second ID are inconsistent.

In this step, the routing device determines the message to be identified successfully in the first N messages to be identified as a sample message, or determines the nth message to be identified as a sample message when none of the first N messages to be identified is successfully identified.

After acquiring the first ID and the second ID, the routing device compares the first ID and the second ID. If the first ID and the second ID are inconsistent, it indicates that the identification ID of the message to be identified by the routing device through the identification model is wrong, which may be caused by degradation of identification accuracy due to untimely updating of the identification model. In this case, the routing device determines that the message to be identified is a sample message, which is used to update the identification model. Therefore, the routing equipment can collect the sample message and the service ID corresponding to the sample message without manual collection and manual calibration, thereby being beneficial to saving manpower and time cost and improving the efficiency of collecting the sample message.

If the first ID and the second ID are consistent, it is indicated that the identification ID of the message to be identified by the routing device through the identification model is correct, and in this case, the routing device may not generate the sample message temporarily.

Optionally, after determining the sample packet, the routing device may remove the header of the sample packet, only the content of the application layer, i.e. the payload, remains, and send the payload of the sample packet and the second ID to the server. In this way, the server, after receiving the payload of the sample message and the corresponding second ID, may determine that an update to the identification model is required, and thus the server may update the identification model based on the collected sample message.

In the embodiment of the application, the routing equipment receives the service ID through the private protocol first, and the service ID is obtained. The routing device stores the correspondence of the service ID, the identification ID, and the second quintuple information, where the service ID is stored along with the correspondence. The routing equipment receives the first N messages to be identified, identifies the nth message to be identified in the first N messages to be identified through an identification model, and determines the identification ID as a first ID if the identification ID meets a first preset value after the identification ID is obtained. Further, the routing device searches for the service ID from the corresponding relationship between the service ID, the identification ID and the first quintuple information based on the first quintuple information of the nth message to be identified. In the case that the routing device finds a service ID satisfying the second preset value, the routing device determines the service ID as the second ID. Thus, the routing device acquires the first ID and the second ID.

Illustratively, the first preset value is a value greater than or equal to 0 and the second preset value is a value greater than 0.

The following describes the process that the routing device firstly identifies the message to be identified through the identification model to obtain the identification ID, and then receives the service ID.

Fig. 5 is a schematic flow chart diagram of yet another method 500 for model updating provided by an embodiment of the present application. The method 500 may be applied to the communication scenario 100 shown in fig. 1, but embodiments of the present application are not limited thereto. The method 500 includes S501 to S505, which specifically include the following steps:

s501, the routing equipment identifies the message to be identified through the identification model to obtain a first ID.

In this step, the routing device receives a message to be identified, where the message to be identified carries first quintuple information. After receiving the message to be identified, the routing equipment starts to identify the message to be identified through the identification model to obtain an identification ID.

The routing device identifies the first N messages to be identified on one connection, and stops the message identification on the one connection until the nth message to be identified is successfully identified. Illustratively, successful recognition results in a recognition ID greater than 0. Or the first N messages to be identified are not successfully identified, which means that the messages cannot be identified, and the routing equipment stops the message identification on the connection. Illustratively, the identification ID obtained from the unrecognizable message is equal to 0. And the routing equipment determines the identification ID obtained by successful identification or the identification ID obtained by the message which cannot be identified as the first ID.

S502, the routing equipment updates mapping relation information based on the first ID and the first quintuple information.

The routing equipment identifies the first message to be identified through the identification model. Whether the identification is successful or not, the routing equipment updates the pre-stored mapping relation information based on the first quintuple information of the first message to be identified.

Similar to the description above for method 300, the routing device updates pre-stored mapping relationship information, including: and adding a group of service IDs, and the corresponding relation between the identification IDs and the first quintuple information into the pre-stored mapping relation information based on the first quintuple information. The specific adding process can be referred to the description of fig. 4, and will not be repeated here.

After the service ID, the corresponding relation between the identification ID and the first quintuple information are added, the routing equipment assigns the identification ID according to the identification result. Illustratively, N >1, if the first message to be identified is not successfully identified, the identification ID is assigned to "-1"; if n=1, the first message to be identified is not successfully identified, and the identification ID is assigned to "0". Illustratively, N is greater than or equal to 1, and if the first message to be identified is successfully identified, the identification ID is assigned a value greater than 0, illustratively, the identification ID is "101".

At this point the routing device has not received the traffic ID, the routing device may illustratively assign the traffic ID to "-1", indicating that the traffic ID is not reported temporarily.

The routing equipment successfully identifies the nth message to be identified in the first N messages to be identified, and the obtained identification ID meets a first preset value, but caches the nth message to be identified under the condition that the service ID is not received temporarily, so as to obtain a second ID for use.

And under the condition that the first message to be identified is not successfully identified, the routing equipment identifies the second message to be identified through the identification model after receiving the second message to be identified, and determines the identification ID of the second message to be identified. If the second message to be identified is successfully identified, the routing device updates the mapping relation information, which comprises the following steps: and updating the values of the identification IDs in the corresponding relation among the service IDs, the identification IDs and the first quintuple information. Illustratively, the value of the identification ID is updated from "-1" to "101".

S503, the terminal device sends a second ID and second quintuple information to the routing device, wherein the second quintuple information is the same as the first quintuple information, and the first quintuple information is the quintuple information of the message to be identified. Accordingly, the routing device receives the second quintuple information and the second ID.

For this step, reference may be made to the description of S301, and the description is omitted here.

It should be understood that, in the embodiment of the present application, the second ID and the second quintuple information are received after the routing device obtains the identification ID of the first packet to be identified.

And S504, the routing equipment acquires a corresponding first ID from the pre-stored mapping relation information based on the second quintuple information. The mapping relation information indicates at least one set of correspondence relation of the service ID, the identification ID and the quintuple information.

In this step, since the first quintuple information and the second quintuple information are the same, the routing device may search the mapping relationship information for the service ID, the correspondence between the identification ID and the first quintuple information based on the second quintuple information, and obtain the identification ID from the searched correspondence. If the identification ID meets the first preset value, the routing equipment determines that the identification ID is the first ID. If the identification ID does not meet the first preset value, the routing device updates the value of the service ID, illustratively, from "-1" to "101".

S505, the routing equipment determines the message to be identified as a sample message under the condition that the first ID and the second ID are inconsistent.

The routing device obtains the second ID based on S503 described above, and the routing device obtains the first ID based on S504 described above. In this way, the routing device can compare the first ID with the second ID, and determine the message to be identified corresponding to the second ID as the sample message under the condition that the first ID and the second ID are inconsistent.

In the embodiment of the application, the routing equipment firstly receives a first message to be identified on a connection through a routing forwarding protocol, and adds a service ID, a corresponding relation between the ID and the first quintuple information in the mapping relation information based on the first quintuple information and the ID of the first message to be identified. And then, the routing equipment receives the service ID and the second quintuple information, wherein the service ID is the second ID. The routing equipment searches the identification ID in the mapping relation information based on the second quintuple information, and if the searched identification ID meets a first preset value, the routing equipment determines the searched identification ID as the first ID. If the found identification ID does not meet the first preset value, the routing equipment updates the service ID, the value of the service ID in the corresponding relation between the identification ID and the first quintuple information, namely, records the second ID, waits for obtaining the identification ID meeting the first preset value, namely, obtains the first ID, and then obtains the second ID from the mapping relation information based on the first quintuple information.

In the embodiments described above with respect to fig. 3 to 5, the routing device receives the traffic ID via a private protocol with the terminal device.

Fig. 6 is a model framework diagram of a proprietary protocol according to an embodiment of the present application. As shown in fig. 6, the terminal device includes a smart life APP and a system module, where the smart life APP may obtain quintuple information of the newly added TCP/UDP connection and an APP name through the system module. The routing equipment comprises a service control (service control) module, a linkMgr module and an upgrading module.

Since the terminal device is connected to the routing device through wireless fidelity (wireless fidelity, wi-Fi), the embodiment of the application corresponds to the local management part, that is, the channel between the terminal device and the routing device is a hypertext transfer protocol (hyper text transfer protocol over secure socket layer, HTTPS) channel based on a secure encryption layer. For remote management, the terminal device connects to the device cloud via a message queue telemetry transport protocol (message queuing telemetry transport, MQTT) first, and then to the routing device via the MQTT.

Based on fig. 6, fig. 7 is a schematic flow chart of yet another method 700 for model update provided by an embodiment of the present application. The method 700 may be applied to the communication scenario 100 shown in fig. 1, but embodiments of the application are not limited thereto. The method 700 includes S701 to S714, which specifically include the following steps:

s701, the intelligent life APP sends a permission request to the system module, wherein the permission request is used for requesting permission to acquire connection information of the APP from the system module. Accordingly, the system module receives the permission request.

The user can use intelligent life APP at the terminal equipment to openThe "join service identification automatic activity optimization" function of the intelligent life APP. At this functional interface, the user can set the APP name that needs to be optimized, e.g.,

The intelligent life APP completes event subscription of connection tracking change when the function of 'joining service identification automatic optimizing activity' is started.

S702, the system module sends a permission response to the intelligent life APP, wherein the permission response is used for allowing the intelligent life APP to acquire permission of connection information of the APP. Accordingly, the smart life APP receives the permission response.

After the system module agrees to allow, the intelligent life APP can acquire connection information of the APP which needs to be optimized and is set from the system module.

S703, the system module sends newly-connected quintuple information and APP names to the intelligent life APP. Accordingly, the smart life APP receives the quintuple information and the APP name.

Illustratively, whenAfter start-up, since the user sets +.>To require an optimized APP, therefore, the system module can track the perception +.>Is a new connection to the network. The system module detects whether the intelligent life APP registers a callback function. If yes, triggering a callback. The system module further judges->If in the optimization term, if yes, the system module sends +_to the intelligent life APP>APP name and quintuple information.

S704, the intelligent life APP sends quintuple information and service ID to the linkMgr module through a private protocol. The service ID is the service ID corresponding to the received APP name. The linkMgr module receives the quintuple information and the service ID.

After receiving the APP name and the quintuple information, the intelligent life APP converts the APP name into a corresponding service ID.

S705, the linkMgr module sends quintuple information and service ID to the service control module. Accordingly, the service control module receives the quintuple information and the service ID.

S706, the service control module updates the mapping relation information.

The process of updating the mapping information can be referred to above, and will not be described here.

S707, the service control module identifies the message to be identified through the identification model to obtain an identification ID.

The service control module can continuously identify the received message to be identified until the identification is successful, and stop identifying the message. Or the message to be identified is not successfully identified, and the message identification is stopped. The message to be identified includes the first N messages on a connection.

S708, the service control module compares whether the identification ID is consistent with the service ID when the identification ID meets the first preset value and the service ID meets the second preset value.

In this step, the routing device triggers a comparison operation if both the identification ID and the service ID meet the requirements. Illustratively, the first preset value is a value greater than or equal to 0 and the second preset value is a value greater than 0.

S709, the service control module determines that the message to be identified is a sample message under the condition that the identification ID is inconsistent with the service ID.

S710, the service control module sends the effective load and service ID of the sample message to the server. Accordingly, the server receives the payload and the service ID of the sample message.

In this step, the service control module may send the payload of the sample packet and the service ID to the server through the HTTPS channel.

S711, the server integrates the samples and screens out high-frequency samples.

In a center-edge networking scenario, a server may receive multiple sample messages from multiple routing devices. Fig. 8 is a schematic diagram of a center-edge networking according to an embodiment of the present application. Illustratively, a total of L routing devices are connected to the server. Each of the L routing devices is connected to at least one terminal device.

The number of routing devices connected to the server in fig. 8 is merely an example, and the number of terminal devices connected to each routing device is merely an example, which is not limited by the embodiment of the present application.

The server receives a plurality of sample messages from the L routing devices aiming at the same service ID through the HTTPS channel. The server uses any data similarity analysis algorithm to calculate the similarity between every two sample messages in a plurality of sample messages of the same service ID, and clusters according to the similarity to obtain a plurality of clustering sets. And determining a target cluster set with the proportion of the number of the sample messages in the total number of the reported plurality of sample messages larger than a preset threshold value from the plurality of cluster sets. And performing de-duplication operation on samples in the target cluster set to obtain a high-frequency sample message which can be used for training the recognition model.

The sample message in the step is a sample message which is not recognized or is not recognized by a plurality of routing devices. After frequency screening, the obtained high-frequency sample message has high reliability. The service ID received by the server is the service ID of the APP concerned by the user, and the server can pertinently strengthen the identification accuracy of the message aiming at the service ID, thereby bringing better use experience for the user.

S712, the server trains the recognition model by using the high-frequency sample message to obtain an updated recognition model.

The server adopts the existing model training technology, and carries out model training based on the training process of the convolutional neural network. The training process comprises the following steps: initializing the weight of the identification model by using the weight trained by the previous version; and inputting the high-frequency sample message into an identification model, and extracting the feature vector of the high-frequency sample message through convolution and pooling of the multi-layer convolution layers. Transmitting the feature vector to a full connection layer, and outputting a recognition result; calculating an error between the identification result and a target value, wherein the target value can be a value obtained by normalizing the service ID; when the error is larger than the expected value, the error is transmitted back to the network, the errors of the full-connection layer, the downsampling layer and the convolution layer are sequentially obtained, and when the error is equal to or smaller than the expected value, training is finished; and updating the weight according to the error, and outputting the updated identification model.

S713, the server sends a hint message to the upgrade module, the hint message being used to hint that the recognition model has been updated. Accordingly, the upgrade model receives the hint message.

After finishing updating the identification model, the server issues the updated identification model to a plurality of routing devices.

S714, the upgrade model completes the upgrade of the identification model based on the prompt message.

The upgrade model may download the updated identification model from the server, and then may identify the traffic type of the message based on the updated identification model.

The following is described in connection with mode two:

fig. 9 is a schematic flow chart diagram of yet another method 900 for model updating provided by an embodiment of the present application. The method 900 may be applied to the communication scenario 100 as shown in fig. 1, but embodiments of the present application are not limited thereto. The method 900 includes steps S901 to S904, which specifically include the following steps:

s901, a terminal device sends a message to be identified to a routing device, wherein the message to be identified comprises first quintuple information and a second ID. Accordingly, the routing device receives the message to be identified. After receiving the message to be identified, the routing equipment can obtain the second ID by analyzing the message to be identified.

Optionally, the terminal device may carry the service ID in the first M messages to be identified in the first N messages to be identified sent to the routing device, where N is greater than or equal to M.

Optionally, the second ID is carried in a header of the message to be identified.

S902, the routing equipment identifies the message to be identified through the identification model, and a first ID is obtained.

And the routing equipment identifies the currently received message to be identified through the identification model to obtain an identification ID. If the identification ID meets the first preset value, the routing equipment determines that the identification ID is the first ID.

The routing device obtains the second ID through S901, and the routing device obtains the first ID through S902.

If the identification ID does not meet the first preset value, the routing equipment updates pre-stored mapping relation information, adds the corresponding relation between the service ID and the identification ID and the first quintuple information, and the service ID meets the second preset value in the corresponding relation, wherein the identification ID does not meet the first preset value. The routing equipment continues to receive the message to be identified, and when the identification ID of the received message to be identified meets a first preset value, the routing equipment determines the identification ID as a first ID. The routing equipment updates the mapping relation information based on the first quintuple information of the message to be identified, namely, updates the service ID and the identification ID in the corresponding relation between the identification ID and the first quintuple information. Illustratively, the identification ID is updated from "-1" to "101".

S903, under the condition that the first ID and the second ID are inconsistent, determining the message to be identified as a sample message, wherein the sample message is used for updating the identification model.

And S904, the routing equipment stores mapping relation information, wherein the mapping relation information indicates the corresponding relation between the first ID, the second ID and the first five-tuple information.

In this step, the routing device stores the mapping relationship information, so that when the routing device receives the subsequent message after obtaining the first ID stop message identification, the routing device can search the second ID in the stored mapping relationship information, determine the service type of the subsequent received message according to the second ID, and perform corresponding processing on the received message.

Alternatively, as shown in fig. 4, the routing device may store the first ID, the second ID, and the correspondence of the first quintuple information in the hash bucket with the first quintuple information as a key.

In the above-described embodiments, it is mentioned that the routing device identifies the first N messages to be identified on one connection, and once there are successfully identified messages to be identified in the first N messages to be identified, or none of the first N messages to be identified are successfully identified, the routing device stops identifying the messages.

In addition to this scheme, optionally, the routing device identifies up to the nth message to be identified, whether there are successfully identified messages to be identified in the first N messages to be identified on a connection. In the first N messages to be identified, if none of the N messages to be identified is successfully identified, the routing device may determine the N messages to be identified as sample messages. If the nth message to be identified in the N messages to be identified is successfully identified, the routing device may determine other messages to be identified except the nth message to be identified in the first N messages to be identified as sample messages.

It should be understood that the sequence numbers of the above processes do not mean the order of execution, and the execution order of the processes should be determined by the functions and internal logic of the processes, and should not be construed as limiting the implementation process of the embodiments of the present application.
