Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to an information processing method and related equipment. Background Art

[0002] Broadband service refers to the way in which network providers provide network services to users. Broadband services have been popularized in households, but there is still much room for improvement in the quality of their services.

[0003] In the communication network of broadband services, the terminal device can send application streams to the gateway device, the gateway device forwards the application streams to the OLT, and the OLT forwards the application streams to the application server. The gateway device can be set up in the home, and the OLT can have a built-in application stream detection (deep packet inspection, DPI) interception board to intercept the application stream, obtain the flow information therein, and upload it to the experience assurance management platform. After the experience assurance management platform obtains the flow information, it can perform data analysis to determine the service quality poor event.

[0004] Among them, the source IP address in the application flow sent by the terminal device is a private network (internet protocol, IP) address. The gateway device, as a network address translation (NAT) device, can convert the private IP address in the application flow sent by the terminal device into a public IP address. Therefore, the application flow intercepted by the gateway device and the traffic information obtained are at the household level (one gateway device is regarded as one household). When a poor service quality event occurs, the experience assurance management platform can only determine the gateway device with the problem based on the traffic information, and cannot further determine the terminal device with the problem. Summary of the invention

[0005] The embodiments of the present application provide an information processing method and related devices for identifying a terminal device based on an application flow.

[0006] The first aspect of the present application provides an information processing method, in which a port pre-allocation table is first received, and the port pre-allocation table is used to indicate the public network IP addresses and port number ranges respectively allocated to multiple terminal devices, wherein the public network IP addresses allocated to the multiple terminal devices are not exactly the same, and the port number ranges allocated to any two terminal devices that are allocated the same public network IP address in the port pre-allocation table do not overlap. Then, when the first public network IP address and the first port number of the public network application flow are obtained, the first terminal device corresponding to the first public network IP address and the first port number can be determined based on the port pre-allocation table. The first terminal device is one of the multiple terminal devices, so that the terminal device corresponding to the sending of the public network application flow can be identified, and then when a poor service quality event occurs, the terminal device where the network failure occurs can be determined to improve the service quality.

[0007] In some possible implementations, the entries of the port pre-allocation table include a public IP address, a port number range, and device information, and the device information includes a MAC address of one of the multiple terminal devices, so that the corresponding terminal device can be identified by the MAC address.

[0008] In some possible implementations, the device information includes a device account and a device type, so more information about the corresponding terminal device can be further obtained through the device account and the device type to improve service quality.

[0010] In some possible implementations, after receiving the public network application flow, the first public network IP address and the first port number can be obtained from the public network application flow, so that the terminal device identification device can obtain the first flow information of the public network application flow.

[0011] In some possible implementations, by receiving first flow information, the first flow information includes the first public IP address and the first port number in the public application flow, so that the terminal device identification device obtains the first public IP address and the first port number of the public application flow.

Then, the port pre-allocation table is sent. Then, when the device that receives the port pre-allocation table receives an application flow, it can obtain the public network IP address and port number of the application flow, and then identify the corresponding terminal device, and then when a poor service quality event occurs, it can determine the terminal device where the network failure occurs to improve the service quality.

[0013] In some possible implementations, before generating the port pre-allocation table, the method includes: accessing multiple terminal devices; recording the private IP addresses and device information of the multiple terminal devices to obtain multiple private IP addresses; determining the public IP address corresponding to each private IP address in the multiple private IP addresses to obtain a NAT table entry, wherein the NAT table entry is used to indicate the mapping from the private IP address to the public IP address, wherein the public IP addresses mapped to any two private IP addresses in the multiple private IP addresses are not exactly the same. Then, the port pre-allocation table can be generated based on the public IP address, the private IP address and the device information.

[0014] In some possible implementations, the method further includes: receiving a private network application flow sent by a first terminal device, the source IP address of the private network application flow is a first private network IP address, and the first terminal device is one of the multiple terminal devices; converting the first private network IP address into a first public network IP address based on the NAT table entry to obtain a public network application flow, the first public network IP address is the public network IP address mapped to the first private network IP address based on the NAT table entry; and sending the public network application flow. Then, the public network IP address and port number of the application flow can be obtained, and then the corresponding terminal device can be identified according to the port pre-allocation table, and then when a poor service quality event occurs, the terminal device where the network failure occurs can be determined to improve the service quality.

[0015] In some possible implementations, the entries of the port pre-allocation table include a public IP address, a port number range, and device information, and the device information includes a MAC address of one of the multiple terminal devices, so that the corresponding terminal device can be identified by the MAC address.

[0036] The embodiments of the present application provide an information processing method and related devices for identifying a terminal device based on an application flow.

[0037] The embodiments of the present application are described below in conjunction with the accompanying drawings.

[0038] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0039] This application can be applied to communication networks. Figure 1-1 and Figure 1-2 As shown, the communication network 100 includes: a terminal device 110, a gateway device 120, an optical line terminal (OLT) 130, a broadband access server (BRAS) 140, an experience assurance management platform 150 and an application server 160.

[0040] The user terminal 110 may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device 110.

[0041] The gateway device 120 may be an access point (AP), an access controller (AC), a router / switch or an optical network terminal (ONT). The gateway device 120 may be set up in a home, an office or other applicable scenarios. For example, an ONT may be set up in a home, also known as an "optical modem". The ONT uses a large-scale integrated chip with a simple circuit, low power consumption, high reliability, and a complete alarm status indication and a perfect network management function.

[0042] Among them, a router / switch is a hardware device that connects two or more user devices and acts as a gateway between user devices. A router / switch is a dedicated intelligent network device that can read the destination address in a message and decide how to transmit the message according to the destination address. A router / switch can understand different protocols, such as the Ethernet protocol used in a local area network and the transmission control protocol / internet protocol (TCP / IP) protocol used in the Internet. In this way, a router / switch can analyze the destination addresses of messages sent from various types of networks, convert non-TCP / IP addresses into TCP / IP addresses, or vice versa; and then transmit each message to the destination address along the best transmission path according to the routing algorithm, so a router / switch can connect a non-TCP / IP network to the Internet.

[0043] OLT 130 is the core component of the optical access network based on optical fiber, which is equivalent to the switch or router in the traditional communication network, and is also a multi-service providing platform. OLT 130 is generally placed at the central office, providing the optical fiber interface of the passive optical fiber network for users. The functions that OLT 130 can achieve include: on the one hand, the signals carrying various services are aggregated at the central office, and sent to the access network according to a certain signal format for transmission to the end user, and on the other hand, the signals from the end user are sent to various service networks according to the service type.

[0044] BRAS140 is a new access gateway for broadband network applications, which can complete data access of user bandwidth, realize broadband Internet access for commercial buildings and residents in residential areas, support ISP wholesale services to users, etc. Exemplarily, a dynamic point-to-point protocol (PPP) connection is established between BRAS140 and terminal device 110. Exemplarily, the network side interface of BRAS140 is connected to the core network device, so that BRAS140 can send a billing start message after the terminal device 110 goes online.

[0045] In some possible implementations, the OLT 130 or the BRAS 140 may have a built-in DPI interception board. The DPI interception board is used to intercept the application flow to obtain the traffic information between the terminal device 110 and the application server 160, and upload it to the experience assurance management platform 150. It should be noted that DPI is a traffic detection and control technology based on the application layer. Enterprises and Internet service providers often use DPI to identify and prevent network attacks, track user behavior, block malware, and monitor network traffic. DPI checks the data and metadata associated with a single application flow. When the application flow approaches the checkpoint, DPI intercepts any protocol violations, viruses, spam, and other anomalies, and prevents the application flow from continuing to pass the checkpoint.

[0046] The experience assurance management platform 150 is used to achieve effective connection between the physical network and business intent, to realize centralized management, control and analysis of the global network downward, to enable resource cloudification, full life cycle automation, and intelligent closed loop driven by data analysis for business and business intent. The experience assurance management platform 150 is mainly used in scenarios such as operator networks, data centers, enterprise campuses, and enterprise dedicated lines, making the network simpler, smarter, more open and secure, and accelerating the business transformation and innovation of operators and enterprises. Exemplarily, the experience assurance management platform 150 can be used as a campus network analyzer, collecting network data in real time through telemetry, using big data analysis and machine learning algorithms to learn network behavior and identify fault modes, helping operation and maintenance personnel to proactively discover most network problems and create an excellent network service assurance experience.

[0047] In the embodiment of the present application, the experience assurance management platform 150 is used as a home network management system, as a cloud management system, for remotely managing the home gateway device 120. In the embodiment of the present application, the DPI interception board built into the gateway device 130 intercepts the application flow data, obtains the flow information between the gateway device 120 and the server, and uploads it to the experience assurance management platform 150. After the experience assurance management platform 150 obtains the flow information, it can perform data analysis to determine the poor service quality event.

[0048] The application server 160 is used to respond to service requests and process them, and provide reliable services. For example, the application server 160 receives a service request from the terminal device 110 and responds to the service request. Therefore, in general, the application server 160 should have the ability to undertake services and guarantee services. The application server 160 needs to have strong processing power, high stability, high reliability, high security, scalability and manageability. In the embodiment of the present application, the application server 160 can be an x86 server, which is also called a complex instruction set computer (CISC) architecture server, that is, a personal computer (PC) server, which is based on the PC architecture and uses an Intel (Intel) or other x86 instruction set compatible processor chip and a Windows operating system.

[0049] The application server 160 may have relatively large differences due to different configurations or performances, and may include at least one central processing unit (CPU) (e.g., at least one processor) and memory, and at least one storage medium (e.g., at least one mass storage device) for storing application programs or data. Among them, the memory and the storage medium may be temporary storage or permanent storage. The program stored in the storage medium may include at least one module, and each module may include a series of instruction operations on the application server 160. Furthermore, the central processing unit may be configured to communicate with the storage medium and execute a series of instruction operations in the storage medium on the application server 160. The application server 160 may also include at least one power supply, at least one wired or wireless network interface, at least one input and output interface, and / or at least one operating system, such as Windows Server, Mac OS X, Unix, Linux, FreeBSD, NetWare, etc. In some feasible implementations, the application server 160 may also be a cloud server, which is not limited here.

[0050] In the communication network 100, the terminal device 110 can send an application flow to the gateway device 120, and the source IP address of the application flow is a private network IP address. Then, the gateway device 120 converts the private network IP address of the application flow into a public network IP address to obtain a new application flow, and the gateway device 120 forwards the new application flow to the OLT 130. Then, the OLT 130 forwards the new application flow to the BRAS 140, and the BRAS 140 sends the new application flow to the application server 160 through the bearer network, so that the application server 160 provides services for the terminal device 110 based on the new application flow. Among them, the gateway device 120 can be set in a home. Figure 1-1 As shown, OLT 130 has a built-in deep packet inspection (DPI) interception board for intercepting application flow data, obtaining traffic information of new application flows between gateway device 120 and application server 160, and uploading it to experience assurance management platform 140. Figure 1-2 As shown, BRAS 140 has a built-in DPI interception board for intercepting application flow data, obtaining traffic information of new application flows between the gateway device 120 and the application server 160, and uploading it to the experience assurance management platform 140. After obtaining the traffic information, the experience assurance management platform 140 can perform data analysis to determine the poor service quality event.

[0051] However, since the source IP address of the new application flow sent by the gateway device 120 to the OLT 130 is a public IP address, the traffic information intercepted by the DPI is at the household level (one ONT is regarded as one household). When a poor service quality event occurs, the experience assurance management platform 140 can only determine the gateway device 120 with the problem based on the traffic information, and cannot further determine the terminal device 110 with the problem.

[0052] To this end, the present application provides an information processing method and related devices for identifying terminal devices based on application flows.

[0053] In the present application, a port pre-allocation table is first received, and the port pre-allocation table is used to indicate the public network IP addresses and port number ranges respectively allocated to multiple terminal devices, wherein the public network IP addresses allocated to the multiple terminal devices are not exactly the same, and the port number ranges allocated to any two terminal devices that are allocated the same public network IP address in the port pre-allocation table do not overlap. Then, when the first public network IP address and the first port number of the public network application flow are obtained, the first terminal device corresponding to the first public network IP address and the first port number can be determined based on the port pre-allocation table. The first terminal device is one of the multiple terminal devices, so that the terminal device corresponding to the public network application flow can be identified, and then when a poor service quality event occurs, the terminal device where the network failure occurs can be determined to improve the service quality.

[0054] In the present application, the OLT or BRAS can intercept the application flow and identify the terminal device based on the application flow, or the OLT or BRAS can obtain traffic information based on the application flow and send it to the experience assurance management platform, and then the experience assurance management platform identifies the terminal device based on the traffic information. The following four embodiments are described respectively. Among them, embodiment one is used to describe the OLT intercepting the application flow and identifying the terminal device based on the application flow; embodiment two is used to describe the BRAS intercepting the application flow and identifying the terminal device based on the application flow; embodiment three is used to describe the OLT obtaining traffic information based on the application flow, sending it to the experience assurance management platform, and then the experience assurance management platform identifies the terminal device based on the traffic information; embodiment four is used to describe the BRAS obtaining traffic information based on the application flow, sending it to the experience assurance management platform, and then the experience assurance management platform identifies the terminal device based on the traffic information.

[0055] See also Figure 2-1 As shown, the information processing method provided in the first embodiment of the present application mainly includes the following steps:

[0056] 201. A gateway device is connected to multiple terminal devices.

[0057] In the embodiment of the present application, when the terminal device is turned on, it can access the gateway device. In some possible implementations, each of the multiple terminal devices can be connected to the gateway device via a transmission medium (such as a twisted pair) or a wireless method (such as Wi-Fi), which is not limited here.

[0058] Exemplarily, a laptop computer or a smart TV (terminal device) can be connected to an optical modem (ONT) via a twisted pair (wired) or Wi-Fi (wireless), or a laptop computer or a smart TV (terminal device) can be connected to a home router via Wi-Fi (wireless), and a home router can be connected to an optical modem (ONT) via a twisted pair. This is not limited here.

[0059] As another example, a mobile phone or tablet (terminal device) can be connected to an optical modem (ONT) via Wi-Fi, or a mobile phone or tablet (terminal device) can be connected to a home router via Wi-Fi (wireless), and a home router can be connected to an optical modem (ONT) via a twisted pair cable, without limitation here.

[0060] 202. The gateway device records the private network IP addresses and device information of multiple terminal devices to obtain multiple private network IP addresses.

[0061] In the embodiment of the present application, after multiple terminal devices access the gateway device, each of the multiple terminal devices can communicate with the dynamic host configuration protocol (DHCP) server through the gateway device, so that each of the multiple terminal devices obtains the private network IP address (including subnet mask) configured by the DHCP server. Then, each of the multiple terminal devices can access the network based on the configured private network IP address to communicate with other devices accessing the network, such as application servers that provide business services.

[0062] It should be noted that the private network IP addresses configured for multiple terminal devices connected to the same gateway device are different. For example, the multiple terminal devices are mobile phones, tablet computers, laptops, smart watches, smart glasses, and smart TVs, and the private network IP addresses obtained are 192.168.1.5, 192.168.1.6, 192.168.1.7, 192.168.1.8, 192.168.1.9, and 192.168.1.10, respectively, which are not limited here.

[0063] In an embodiment of the present application, after each of the multiple terminal devices is configured with a private IP address, the gateway device can record the private IP address of each of the multiple terminal devices to obtain multiple private IP addresses.

[0064] 203. The gateway device determines a public IP address corresponding to each of the multiple private IP addresses, and obtains a NAT entry, where the NAT entry is used to indicate a mapping from a private IP address to a public IP address, wherein the public IP addresses mapped to any two of the multiple private IP addresses are not exactly the same.

[0065] In some possible implementations, the gateway device may be allocated a certain number of public IP addresses, such as 202.49.1.1 to 255. Among the multiple terminal devices in the local area network formed by the gateway device, the gateway device may allocate different public IP addresses to different terminal devices. That is, two terminal devices connected to the same gateway device may be allocated the same public IP address or different public IP addresses.

[0066] Exemplarily, as shown in Table 1, it is an example of different public IP addresses allocated by the gateway device to different terminal devices.

[0067] Table 1

[0068] Device Type MAC Address Public IP address cell phone AF:XX 202.49.1.2 Tablet EF:XX 202.49.1.2 Laptop AE:FE 202.49.1.2 Smartwatch BF:XX 202.49.1.3 Smart glasses CF:XX 202.49.1.3 Smart TV DE:FE 202.49.1.3

[0069] Among them, the public IP addresses assigned to mobile phones, tablets, and laptops (terminal devices) are all 202.49.1.2, and the public IP addresses assigned to smart watches, smart glasses, and smart TVs (terminal devices) are all 202.49.1.3. Among them, the MAC address is the unique identifier of a terminal device.

[0070] In an embodiment of the present application, after the gateway device allocates public IP addresses to multiple terminal devices, the gateway device can generate corresponding NAT entries. In some possible implementations, the NAT entry includes multiple entries, each of which is a mapping from a private IP address to a public IP address. It should be noted that different private IP addresses can be mapped to the same public IP address.

[0071] Exemplarily, as shown in Table 2, it is an example of NAT table entries generated by a gateway device for multiple terminal devices.

[0072] Table 2

[0073] Private IP address Public IP address 192.168.1.5 202.49.1.2 192.168.1.6 202.49.1.2 192.168.1.7 202.49.1.2 192.168.1.8 202.49.1.3 192.168.1.9 202.49.1.3 192.168.1.10 202.49.1.3

[0074] Among them, private IP addresses 192.168.1.5, 192.168.1.6, and 192.168.1.7 are mapped to the same public IP address 202.49.1.2; private IP addresses 192.168.1.8, 192.168.1.9, and 192.168.1.10 are mapped to the same public IP address 202.49.1.3.

[0075] In some possible implementations, the NAT entry may also include device information of each terminal device in the multiple terminal devices, such as device type, MAC address, and device account, which is not limited here. Exemplarily, as shown in Table 3, another example of NAT entries generated by the gateway device for multiple terminal devices.

[0076] Table 3

[0078] In some possible implementations, the NAT table entry may also include network information of each terminal device in the multiple terminal devices, such as access mode, access frequency band (if access mode is Wi-Fi), signal strength, etc., which is not limited here. Exemplarily, as shown in Table 4, another example of NAT table entries generated by the gateway device for multiple terminal devices.

[0079] Table 4

[0080]

[0081] In some possible implementations, the NAT table entry may further include other information, which is not limited here.

[0082] 204. The gateway device generates a port pre-allocation table, where the port pre-allocation table is used to indicate the public IP addresses and port number ranges respectively allocated to multiple terminal devices, wherein the public IP addresses allocated to the multiple terminal devices are not exactly the same, and the port number ranges allocated to any two terminal devices that are allocated the same public IP address in the port pre-allocation table do not overlap.

[0083] In some possible implementations, after the gateway device generates NAT table entries corresponding to multiple terminal devices, the gateway device can allocate a port number range (i.e., one or more port numbers) to the multiple terminal devices based on the NAT table entries to obtain a port pre-allocation table. In the port pre-allocation table, different port numbers can be allocated to different terminal devices with the same public IP address, and the port numbers allocated between different terminal devices with the same public IP address do not overlap.

[0084] In some possible implementations, the port pre-allocation table includes multiple table entries, each of which includes a public IP address, a port number range, and device information, and the device information includes a MAC address of one of the multiple terminal devices.

[0085] Exemplarily, as shown in Table 5, it is an example of a gateway device generating a port pre-allocation table for multiple terminal devices.

[0087] MAC Address Public IP address Port number range AF:XX 202.49.1.2 10001～11000 EF:XX 202.49.1.2 11001～12000 AE:FE 202.49.1.2 12001～13000 BF:XX 202.49.1.3 10001～11000 CF:XX 202.49.1.3 11001～12000 DE:FE 202.49.1.3 12001～13000

[0088] Among them, the port numbers assigned to mobile phones (mac address: AF:XX) and smart watches (mac address: BF:XX) are both 1000111000, but the public IP addresses corresponding to mobile phones and smart watches are different; the port numbers assigned to tablet computers (mac address: EF:XX) and smart glasses (mac address: CF:XX) are both 11001~12000, but the public IP addresses corresponding to tablet computers (mac address: AE:FE) and smart glasses (mac address: DE:FE) are different; the port numbers assigned to laptops and smart TVs are both 12001~13000, but the public IP addresses corresponding to laptops and smart TVs are different.

[0089] It should be noted that the port number is used to distinguish different terminal devices with the same public IP address. For example, a mobile phone and a tablet have the same public IP address 202.49.1.2, but the port number range of the mobile phone is 10001-11000, while the port number range of the tablet is 11001-12000. If the public IP address of an application flow is 202.49.1.2 and its port number is 10010, then it can be determined that the origin of the application flow is a mobile phone; if the public IP address of an application flow is 202.49.1.2 and its port number is 11010, then it can be determined that the origin of the application flow is a tablet.

[0090] It should be noted that a terminal device can distinguish different data streams through different port numbers. For example, for a mobile phone, its public IP address is 202.49.1.2, and the port number range is 10001 to 11000. Then, the port number of the application stream sent by a chat software in the mobile phone is 10001, and the port number of the application stream sent by a game software in the mobile phone is 10002.

[0091] In some possible implementations, the gateway device may generate a port pre-allocation table that fixes all port numbers. For example, all port numbers of the gateway device are 10001-13000, wherein mobile phones, tablet computers, and laptops with the same public IP address are respectively allocated port numbers in the range of 10001-11000, 11001-12000, and 12001-13000.

[0092] In some possible implementations, the gateway device may generate a fixed port pre-allocation table for a portion of the port numbers, and leave the other portion of the port numbers to be allocated. When the port numbers of a certain terminal device are insufficient, more port numbers may be allocated to the terminal device, forming a semi-dynamic allocation of port numbers. For example, all the port numbers of the gateway device are 10001 to 20000, wherein the mobile phones, tablet computers, and laptops with the same public network IP address are respectively allocated port numbers ranging from 10001 to 11000, 11001 to 12000, and 12001 to 13000. The remaining port numbers to be allocated are 13001 to 20000. When the port numbers of the laptop are insufficient, 13001 to 14000 may be allocated to the laptop.

[0093] In some possible implementations, the gateway device may generate a fixed port pre-allocation table, but set all port numbers to be allocated. When a terminal device needs a port number, the port number is allocated to the terminal device, forming a fully dynamic allocation of port numbers. For example, all port numbers of the gateway device are 10001 to 20000. For mobile phones, tablet computers and laptops with the same public network IP address, when the mobile phone is online, the gateway device allocates port numbers in the range of 10001 to 11000 for the mobile phone; when the tablet computer is online, the gateway device allocates port numbers in the range of 11001 to 12000 for the tablet computer; when the laptop computer is online, the gateway device allocates port numbers in the range of 12001 to 13000 for the laptop computer. The remaining port numbers to be allocated are 13001 to 20000. When the port numbers of laptops are insufficient, 13001 to 14000 can be allocated to laptops; when the port numbers of mobile phones are insufficient, 14001 to 15000 can be allocated to mobile phones; when the port numbers of tablets are insufficient, 15001 to 16000 can be allocated to tablets. The remaining port numbers will continue to be allocated.

[0094] In some possible implementations, there may be other ways of allocating port numbers, which are not limited here.

[0095] In some possible implementations, the device information includes a device account and a device type of one of the multiple terminal devices.

[0096] Exemplarily, as shown in Table 6, it is an example of a gateway device generating a port pre-allocation table for multiple terminal devices.

[0097] Table 6

[0098] Device Account Device Type MAC Address Public IP address Port number range 35… cell phone AF:XX 202.49.1.2 10001～11000 26… Tablet EF:XX 202.49.1.2 11001～12000 18… Laptop AE:FE 202.49.1.2 12001～13000 26… Smartwatch BF:XX 202.49.1.3 10001～11000 36… Smart glasses CF:XX 202.49.1.3 11001～12000 27… Smart TV DE:FE 202.49.1.3 12001～13000

[0099] In some possible implementations, the device information includes an access mode, an access frequency (if using a Wi-Fi access mode), and a signal strength of one of the multiple terminal devices.

[0100] Exemplarily, as shown in Table 7, it is an example of a gateway device generating a port pre-allocation table for multiple terminal devices.

[0103] 205. The gateway device sends the port pre-allocation table to the OLT.

[0104] In the embodiment of the present application, after the gateway device generates the port pre-allocation table, the port pre-allocation table can be sent to the OLT. In some possible implementations, the gateway device can periodically send the port pre-allocation table to the OLT, or after updating the port pre-allocation table and obtaining the updated port pre-allocation table, send the updated pre-allocation table to the OLT, which is not limited here.

[0105] 206. The first terminal device sends a private network application flow to the gateway device. The source IP address of the private network application flow is the first private network IP address. The first terminal device is one of the multiple terminal devices.

[0106] In an embodiment of the present application, the first terminal device is one of a plurality of terminal devices connected to a gateway device. The first private network IP address is a private network IP address configured for the first terminal device, and the first port number is related to the service to which the private network application flow belongs. When the first terminal device is connected to the gateway device, the first terminal device can send a private network application flow to the gateway device, the destination of the private network application flow is an application server, the source IP address of the private network application flow is the first private network IP address of the first terminal device, and the source port number of the private network application flow is the first port number.

[0107] Exemplarily, the first terminal device is a mobile phone, the source IP address of the private network application flow is 192.168.1.5 (ie, the first private network IP address), ie, the private network IP address of the mobile phone, the private network application flow comes from the chat software, and the source port number of the private network application flow is 10001.

[0108] Exemplarily, as shown in Table 8, it is an example of multiple application flows sent by the first terminal device to the gateway device.

[0109] Table 8

[0110] Timestamp Private IP address Port Number 11：00 192.168.1.5 10001 11：01 192.168.1.5 11010 12：00 192.168.1.5 11011

[0111] As shown in Table 8, the source IP addresses of multiple application flows are the private IP address 192.168.1.5, indicating that they all come from the same terminal device, and the timestamps of sending each application flow are 11:00 / 11:01 / 12:00. However, the port numbers of multiple application flows are different, so it can be determined that these application flows come from different application types, such as chat software, games, and shopping applications.

[0112] 207. The gateway device converts the private network application flow into a public network application flow, where the source IP address of the public network application flow is the first public network IP address corresponding to the first private network IP address.

[0113] In an embodiment of the present application, after the gateway device receives the private network application flow, it can obtain the first private network IP address in the private network application flow, and determine the first public network IP address corresponding to the first private network IP address according to the NAT table entry. Exemplarily, the first private network IP address is 192.168.1.5, and the NAT table entry shown in Table 2 can determine the corresponding first public network IP address to be 202.49.1.2. Another exemplary embodiment, the first private network IP address is 192.168.1.10, and the NAT table entry shown in Table 2 can determine the corresponding first public network IP address to be 202.49.1.3.

[0114] It should be noted that the gateway device does not change the source port number of the private network application flow, that is, the source port number of the public network application flow is still the first port number.

[0115] Exemplarily, as shown in Table 9, it is an example of multiple application streams sent by different terminal devices and received by the gateway device.

[0116] Table 9

[0117] Timestamp Private IP address Port Number 11：00 192.168.1.5 10001 11：01 192.168.1.5 11010 11：40 192.168.1.6 10001 11：45 192.168.1.6 10001 11：50 192.168.1.8 11011 12：00 192.168.1.5 11011

[0118] As shown in Table 9, the application flows with the same private IP address come from the same terminal device. For example, the three application flows with the private IP address of 192.168.1.5 come from the same terminal device, the two application flows with the private IP address of 192.168.1.6 come from the same terminal device, and the one application flow with the private IP address of 192.168.1.8 comes from another terminal device. It can be seen that the above six application flows come from three different terminal devices. The three application flows from the same terminal device (private IP address is 192.168.1.5) have different port numbers, indicating that the three application flows come from different application types. The two application flows from the same terminal device (private IP address is 192.168.1.6) have the same port number, indicating that the two application flows come from the same application type.

[0119] Exemplarily, then, the gateway device may convert the private IP addresses of multiple application flows as shown in Table 9 into public IP addresses. Exemplarily, as shown in Table 10, it is an example of the gateway device converting the private IP addresses of multiple application flows received into public IP addresses.

[0120] Table 10

[0121] Timestamp Public IP address Port Number 11：00 202.49.1.2 10001 11：01 202.49.1.2 11010 11：40 202.49.1.2 10001 11：45 202.49.1.2 10001 11：50 202.49.1.3 11011 12：00 202.49.1.2 11011

[0122] As shown in Table 10, the private IP addresses 192.168.1.5 and 192.168.1.6 can be determined to have a corresponding public IP address of 202.49.1.2 according to Tables 3 to 5, and the private IP address 192.168.1.8 can be determined to have a corresponding public IP address of 202.49.1.3 according to Tables 3 to 5, thus obtaining Table 10. However, the gateway device does not change the port number of the application flow.

[0123] 208. The gateway device sends the public network application flow.

[0124] In an embodiment of the present application, after the gateway device converts the first private network IP address in the private network application flow into the first public network IP address and obtains the public network application flow, the public network application flow can be sent to the application server through the gateway device.

[0125] 209. The OLT intercepts the public network application flow, and obtains the first public network IP address and the first port number in the public network application flow.

[0126] In an embodiment of the present application, the OLT can obtain the source IP address in the public network application flow to obtain the first public network IP address. The OLT can also obtain the port number of the public network application flow to obtain the first port number. Exemplarily, the OLT can obtain the five-tuple (source IP address, source port number, destination source IP address, destination port number and transport layer protocol) of the public network application flow, wherein the source IP address is the first public network IP address, and the source port number is the first port number. For example, the first port number is 10001, and the first public network IP address is 202.49.1.2.

[0127] 210. The OLT determines a first terminal device corresponding to a first public network IP address and a first port number based on a port pre-allocation table, where the first terminal device is one of the multiple terminal devices.

[0128] In an embodiment of the present application, when the OLT determines that the data flow corresponding to the private network application flow is a poor service quality event, the OLT can identify the corresponding first terminal device through the port pre-allocation table according to the first port number and the first public network IP address of the private network application flow. Exemplarily, the first port number is 10001, and the first public network IP address is 202.49.1.2. Based on the port pre-allocation table shown in Table 5, it can be determined that the first terminal device is a terminal device with a MAC address of AF:XX. Exemplarily, based on the port pre-allocation table shown in Table 6, it can be determined that the MAC address of the first terminal device is AF:XX, the device type is a mobile phone, and the device account is 35... The terminal device. Exemplarily, based on the port pre-allocation table shown in Table 7, it can be determined that the MAC address of the first terminal device is AF:XX, the device type is a mobile phone, the device account is 35..., the access method is Wi-Fi, the access frequency band is 2.4Ghz, and the signal strength is 6db.

[0129] Exemplarily, as shown in Table 11, it is an example of an OLT identifying a corresponding terminal device according to a public network IP address and a port pre-allocation table (taking Table 5 as an example) in a plurality of application flows to be received.

[0130] Table 11

[0131] Timestamp Public IP address Port Number MAC Address 11：00 202.49.1.2 10001 AF:XX 11：01 202.49.1.2 11010 EF:XX 11：40 202.49.1.2 10001 AF:XX 11：45 202.49.1.2 10001 AF:XX 11：50 202.49.1.3 11011 CF:XX 12：00 202.49.1.2 11011 EF:XX

[0132] As shown in Table 11, the MAC address of the terminal device from which each application flow comes can be determined. Since the MAC address is a unique identifier of the terminal device, the corresponding terminal device is determined.

[0133] In some possible implementations, if the port pre-allocation table is as shown in Tables 6 to 7, the OLT may also determine more information of the terminal device.

[0134] Exemplarily, as shown in Table 12, it is an example of the OLT identifying more information of the corresponding terminal device according to the public network IP addresses and port pre-allocation table (taking Table 6 as an example) in the multiple application flows to be received.

[0137] As shown in Table 11, the device account and device type of the terminal device from which each application flow comes can be determined.

[0138] Exemplarily, as shown in Table 13, it is an example of an OLT identifying more information of a corresponding terminal device according to the public network IP addresses and port pre-allocation table (taking Table 7 as an example) in multiple application flows to be received.

[0141] As shown in Table 13, the device account and device type of the terminal device from which each application flow comes can be determined.

[0142] In the present application, a port pre-allocation table is first received, and the port pre-allocation table is used to indicate the public network IP addresses and port number ranges respectively allocated to multiple terminal devices, wherein the public network IP addresses allocated to the multiple terminal devices are not exactly the same, and the port number ranges allocated to any two terminal devices that are allocated the same public network IP address in the port pre-allocation table do not overlap. Then, when the first public network IP address and the first port number of the public network application flow are obtained, the first terminal device corresponding to the first public network IP address and the first port number can be determined based on the port pre-allocation table. The first terminal device is one of the multiple terminal devices, so that the terminal device corresponding to the public network application flow can be identified, and then when a poor service quality event occurs, the terminal device where the network failure occurs can be determined to improve the service quality.

[0143] For example, Figure 2-2 As shown, currently 20% of network problems are attributed to the resource side (i.e., the server, i.e., 20% of the poor quality events can determine the corresponding server), 10% of network problems are attributed to the network side (i.e., gateway devices, BRAS, OLT, etc., plus 10% of the poor quality events can determine the corresponding gateway devices, BRAS, OLT), and the remaining 70% of network problems are attributed to the home side (i.e., terminal devices, respectively, Wi-Fi access terminal devices have network problems, or other access terminal devices have network problems). This application locates the source of the remaining 70% of network problems by identifying the terminal devices.

[0151] In the embodiment of the present application, after the gateway device generates the port pre-allocation table, the port pre-allocation table can be sent to the BRAS.
