Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device, electronic device, and computer program product for generating a protocol message. Background Art

[0002] With the increasing popularity of network construction based on IP technology and the continuous enrichment of user service types, the demand for more refined and flexible control capabilities for user service data is increasing. At present, OLT has become the main access device for broadband. Its upstream BRAS cannot or is difficult to obtain user port information from the Ethernet data packet of the PPPoE protocol, so it cannot perform unified authentication management on user ports and cannot effectively prevent user accounts from being stolen. Therefore, it is necessary to strengthen the identification of user ports (also known as user lines). In accordance with the requirements of the industry standard "Access Network Technical Requirements Broadband-User Access Line (Port) Identification" (YD / T 2275-2011), the mainstream uses PPPoE+ technology to realize the identification of user ports (also known as user lines), and implements accurate binding and traceability through radius, but the existing technology has great limitations.

[0003] 1) PPPoE+ is implemented on access devices (OLT, switches, etc.), and can correctly identify users under normal circumstances. However, during maintenance work such as faults and tests, when using personal terminals to perform dial-up tests on non-user access lines, it is necessary to modify the access devices at the test points, making the test very complicated.

[0004] 2) During automated simulation testing, the user's information in RADIUS needs to be modified, and the test cannot be implemented without the tested user's awareness.

[0005] 3) It does not consider how to handle the forged user line information on the access device.

[0006] Therefore, the existing solution requires the access device to identify PADI and PADR data by inserting the user line identification attribute field. In this mode, the access device is indispensable and must support PPPoE+, which is very inconvenient in scenarios such as troubleshooting and service testing. It is impossible to ensure that the tested user is unaware, and there is a risk of user line information being misused, resulting in theft of accounts.

[0007] With respect to the problem in the prior art that user line information is at risk of being misused, no effective solution has been proposed so far. Summary of the invention

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] First, some nouns or terms that appear in the description of the embodiments of the present application are subject to the following explanations:

[0036] PPPoE: PPP over Ethernet, Ethernet Point-to-Point Protocol, is a network tunneling protocol that encapsulates Point-to-Point Protocol (PPP) in an Ethernet framework.

[0037] PPPoE+: PPPoE Intermediate Agent is an extension and enhancement of the traditional PPPoE (Point-to-Point Protocol over Ethernet). It is mainly used to implement connection authentication and data transmission between user terminals and broadband access servers in an Ethernet environment.

[0038] BRAS: Broadband Remote Access Server, which is responsible for authentication, authorization and accounting (AAA) of user access. It can verify the user's identity information, determine whether the user has the right to access the network, and allocate corresponding network resources and permissions to the user.

[0039] RADIUS: Remote Authentication Dial In User Service, the RADIUS server is responsible for authenticating the user's identity. When a user tries to connect to the network, the access device (such as BRAS) sends the user's authentication information to the RADIUS server.

[0040] OLT: Optical Line Terminal, OLT is mainly responsible for converting optical signals from the upper network into electrical signals, and distributing the signals to each ONU (Optical Network Unit) through the optical fiber distribution network.

[0041] PDA: Personal Digital Assistant, which can store large amounts of data and has certain office software functions.

[0042] PADI: PPPoE Active Discovery Initiation, PPPoE active discovery initial message, is the initial discovery message sent by the client (user-end device) when establishing a PPPoE connection on Ethernet.

[0043] PADR: PPPoE Active Discovery Request, PPPoE active discovery request message, is an important message in the process of establishing a PPPoE connection on Ethernet. When the client receives the PADO (PPPoE Active Discovery Offer) message responded by the access device, it selects one of the access devices and sends a PADR message to the access device to confirm the connection request.

[0044] According to an embodiment of the present invention, an embodiment of a method for generating a protocol message is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0045] Figure 1 A method for generating a protocol message according to an embodiment of the present invention is described below. Figure 1 ,like Figure 1 As shown, the method comprises the following steps:

[0046] Step S102, the user terminal obtains user line information of the user terminal;

[0047] Step S104, based on the user line information, generate a discovery phase target message of the Ethernet Point-to-Point Protocol, wherein the discovery phase target message at least includes: a net load field, an Ethernet Point-to-Point Protocol tag is added to the net load field, and the Ethernet Point-to-Point Protocol tag is set with user line information.

[0048] In the above-mentioned embodiment of the present application, the user terminal obtains the user line information of the user terminal; based on the user line information, a discovery phase target message of the Ethernet point-to-point protocol is generated, wherein the discovery phase target message at least includes: a net load field, an Ethernet point-to-point protocol tag is added to the net load field, and the user line information is set in the Ethernet point-to-point protocol tag, so that the user line information is directly added to the discovery phase target message generated by the user terminal, so that after the discovery phase target message is generated by the user terminal and before the discovery phase target message is transmitted to the access device of the Ethernet, there is no need to modify the discovery phase target message, thereby achieving the technical effect of preventing a third-party device from intercepting the user line information for misuse, thereby solving the technical problem of the risk of user line information being misused in the prior art.

[0049] In the above step S102, the user terminal may be a personal terminal, such as a communication terminal such as a personal computer PC or a handheld terminal PDA, for requesting access to the Ethernet based on the Ethernet Point-to-Point Protocol PPPoE.

[0050] It should be noted that PPPoE (Point-to-Point Protocol over Ethernet) does include two main stages: the Discovery Stage and the PPP Session Stage.

[0051] Optionally, the main purpose of the discovery stage is to locate an access device in the network and establish an initial connection for a PPPoE session.

[0052] Optionally, the access device may be a broadband remote access server BRAS.

[0053] Optionally, the Discovery Stage includes the following steps:

[0054] PADI (PPPoE Active Discovery Initiation): The user terminal broadcasts a PADI message to find available access devices.

[0055] PADO (PPPoE Active Discovery Offer): After receiving the PADI message, the access device will unicast a PADO message if it can provide the required service.

[0056] PADR (PPPoE Active Discovery Request): The user terminal selects one from multiple PADO messages that may be received and sends a PADR message to the selected access device to request to establish a session.

[0057] PADS (PPPoE Active Discovery Session-confirmation): After receiving the PADR message, the access device generates a unique session ID and sends the session ID to the user terminal through the PADS message to confirm the establishment of the session.

[0058] After completing these steps, the user terminal and the access device have established a PPPoE session and know the Ethernet address and session identifier of the other party.

[0059] Optionally, the PPP Session Stage is to perform a standard PPP process based on the PPPoE session established during the discovery phase. This stage includes the following steps:

[0060] LCP (Link Control Protocol) negotiation: Both parties establish, configure and detect data link connections through LCP negotiation. This includes negotiating working modes (such as single-link connection or multi-link connection), maximum receive unit (MRU) and other parameters.

[0061] Authentication stage: User authentication is performed through PAP (Password Authentication Protocol) or CHAP (Challenge Handshake Authentication Protocol) to verify the legitimacy of the username and password.

[0062] NCP (Network Control Protocol) negotiation: Negotiation is performed for different network layer protocols, such as IPCP (IP Control Protocol) used to configure the user's IP address and DNS server address.

[0063] After completing these PPP negotiations, both parties can transmit network layer data packets on the PPPoE session. If you need to end the PPPoE session, either party can send a PADT (PPPoE Active Discovery Terminate) message to terminate the session.

[0064] In summary, the above discovery stage (Discovery Stage) and point-to-point protocol session stage (PPP SessionStage) together constitute the complete workflow of the PPPoE protocol, allowing users to connect to the remote network via Ethernet and enjoy various network services.

[0065] Figure 2 Schematic diagram of a conventional PPPoE+ protocol exchange process according to an embodiment of the present invention. Figure 2 As shown in the figure, PPPoE+ (PPPoE Intermediate Agent) is an extension and enhancement of the traditional PPPoE (Point-to-Point Protocol over Ethernet), and is mainly used to implement connection authentication and data transmission between user terminals and broadband access servers in an Ethernet environment. In the PPPoE+ protocol exchange process, a PPPoE intermediate agent / agent (PPPoE Intermediate Agent / Agent) is added between the user terminal Client and the broadband remote access server BRAS, so that the active discovery initial message PADI and the active discovery request message PADR sent by the user terminal Client to the broadband remote access server BRAS can be intercepted, and the user line information uPortID is inserted into the active discovery initial message PADI and the active discovery request message PADR.

[0066] However, the user line information uPortID in the target message (such as PADI or PADR) in the discovery phase is added by a proxy server (such as a PPPoE intermediate agent / agent), so the user line information uPortID is also provided by the proxy server. Furthermore, since the security of the proxy server cannot be controlled, the user line information uPortID provided by the proxy server is at risk of being counterfeit.

[0067] In the above step S104, the discovery phase target message can be a PPPoE frame, and the PPPoE frame exists as the payload of the Ethernet frame. When an Ethernet frame is a PPPoE frame, its type / length field (Len / Type field) should be 0x8863 (indicating the discovery phase of PPPoE) or 0x8864 (indicating the session phase of PPPoE, that is, the PPP session phase).

[0068] Figure 3 Schematic diagram of a PPPoE frame structure according to an embodiment of the present invention. Figure 3As shown in the figure, the PPPoE frame contains fields such as version number (Ver), type (Type), code (Code), session ID (Session-ID, also known as session identifier), length (Length) and net load (Payload). The Payload field has different formats in different stages. For example, in the discovery stage, some tags (such as Ethernet point-to-point protocol tags) will be filled in the Payload; in the session stage, the Payload carries the PPP message.

[0069] Optionally, the target message in the discovery phase includes: an active discovery initial message PADI and an active discovery request message PADR.

[0070] Optionally, the message structure of PADI includes: an Ethernet Header and a PPPoE Header (PoE Header).

[0071] Optionally, the Ethernet header includes at least: a destination MAC address (stination MAC Address), such as a broadcast address 0xffffffffffff; a source MAC address (Source MAC Address), such as a client's MAC address; and a type / length (Type / Length), such as "0x0886" indicating the PPPoE protocol.

[0072] Optionally, the PPPoE header includes at least: version (Ver), such as "0x1" indicating PPPoE version 1; type (Type): such as "0x1" indicating PPPoE in combination with the Ver field; code (Code): such as "0x09" indicating a PADI message; session identifier (Session ID): such as the discovery phase session ID is 0, i.e. "0x0000"; length (Length): indicating the length of the subsequent Payload (excluding Ethernet and PPPoE headers); payload field (Payload).

[0073] Optionally, the payload field (Payload) includes: a service name tag (Service-Name TAG) and a Point-to-Point Protocol over Ethernet tag, ie, a PPPoE tag (PPPoE Tag).

[0074] Optionally, the service name tag includes: tag type (Tag Type): such as 0x0101; tag length (TagLength): the length of the subsequent Value field; value field (Value): such as a character string of the service name (usually an ASCII-encoded character string).

[0075] Optionally, the Ethernet point-to-point protocol tag includes: tag type (Tag Type): such as 0x0105; tag length (Tag Length): such as 0x0004 (assuming that the Value field is 4 bytes); value field (Value): such as "0x000DE9" + user line information, where the user line information should follow 0x000DE9 immediately, and the specific value is filled in according to the actual situation.

[0076] Optionally, the message structure of PADR is similar to the message structure of PADI, and will not be described in detail here.

[0077] As an optional embodiment, generating a discovery phase target message of the Ethernet Point-to-Point Protocol based on user line information includes: generating a discovery phase preset message through a user terminal, wherein the discovery phase preset message includes at least: a net load field; adding an Ethernet Point-to-Point Protocol label to the net load field of the discovery phase preset message through the user terminal, wherein the Ethernet Point-to-Point Protocol label includes at least: a value field; and splicing the user line information at the back end of the value field of the Ethernet Point-to-Point Protocol label of the discovery phase preset message through the user terminal to obtain a discovery phase target message.

[0078] In the above-mentioned embodiment of the present application, the user terminal can generate a preset message for the discovery phase, and an Ethernet point-to-point protocol tag can be added to the net load field part of the preset message for the discovery phase, and the Ethernet point-to-point protocol tag has at least a value field. Furthermore, when generating the preset message for the discovery phase, the user line information of the user terminal can be directly spliced ​​at the back end of the value field of the Ethernet point-to-point protocol tag in the preset message for the discovery phase, thereby realizing the generation of the preset message for the discovery phase.

[0079] Optionally, the preset messages in the discovery phase include: an active discovery initial message PADI and an active discovery request message PADR.

[0080] As an optional embodiment, generating a discovery phase target message of the Ethernet Point-to-Point Protocol based on user line information includes: based on the user line information, generating an active discovery initial message for broadcasting to a network server through a user terminal, wherein the active discovery initial message is a discovery phase target message.

[0081] In the above-mentioned embodiment of the present application, when the generated discovery phase target message is the discovery phase initial message PADI with added user line information, the discovery phase target message can be broadcast in the Ethernet in the original manner of the discovery phase initial message PADI to find available access devices, thereby realizing the application of the discovery phase initial message PADI with added user line information.

[0082] As an optional embodiment, generating a discovery phase message of the Ethernet Point-to-Point Protocol based on user line information includes: receiving, through a user terminal, an active discovery proposal message returned by a network server in response to an active discovery initial message; and generating, through the user terminal, an active discovery request message in response to the active discovery proposal message, wherein the active discovery request message is a discovery phase target message.

[0083] In the above-mentioned embodiment of the present application, the network server may be an access device in the Ethernet or a management device of the access device. The network server may generate an active discovery proposal message PADO in response to an active discovery initial message and select at least one access device in the Ethernet that can provide access to the user terminal. Then, the user terminal may generate an active discovery request message PADR with added user line information in response to the active discovery proposal message PADO, thereby realizing the application of the active discovery request message PADR with added user line information.

[0084] As an optional embodiment, the user terminal obtains the user line information of the user terminal, including: identifying the terminal information of the user terminal, wherein the multiple information items in the terminal information include at least: an access node identifier, a rack, a frame, a slot, a sub-slot, an access port of the user terminal and an optical network identifier of the optical network unit; arranging the multiple information items in the following order to obtain the user line information: an access node identifier, a rack, a frame, a slot, a sub-slot, an access port and an optical network identifier.

[0085] In the above-mentioned embodiment of the present application, the user line information is generated based on multiple information items in the terminal information of the user terminal, which are arranged in a specific order. Therefore, by acquiring the terminal information of the user terminal, then extracting each information item in the terminal information, and filling the extracted information items into a specific order, the user line information can be obtained, thereby realizing the generation of the user line information.

[0086] Optionally, the PPPoE+ data format adopted by the user line information is as follows: “AccessNodeIdentifier / ANI_rack / ANI_frame / ANI_slot / ANI_subslot / ANI_port / ONU_ID”.

[0087] For example, according to multiple information items in the terminal information, the constructed user line information may be: “DeviceName / rack / frame / slot / subslot / port / 0000000000001A2B3C4D5E6F EP”.

[0088] As an optional embodiment, after generating a discovery phase target message of the Ethernet Point-to-Point Protocol based on user line information, the method also includes: when the discovery phase target message is an active discovery proposal message, receiving an active discovery confirmation message returned by the network server through the user terminal, wherein the active discovery confirmation message includes at least: a session identifier; and generating a Point-to-Point Protocol session based on the session identifier in response to the active discovery confirmation message through the user terminal.

[0089] In the above-mentioned embodiment of the present application, when the target message in the discovery phase is an active discovery proposal message PADR, the active discovery confirmation message PADS returned by the network server to the user terminal in response to the active discovery proposal message PADR carries a session identifier, and then the user terminal, in response to the active discovery confirmation message PADS, can establish and generate a point-to-point protocol session, i.e., a PPP session, based on the session identifier SESSION_ID carried in the active discovery confirmation message PADS.

[0090] As an optional embodiment, after generating a point-to-point protocol session based on a session identifier through a user terminal in response to an active discovery confirmation message, the method also includes: obtaining user account information and password information through the user terminal; and initiating authentication of the user terminal through the point-to-point protocol session based on the user account information and password information.

[0091] In the above-mentioned embodiments of the present application, when establishing a point-to-point protocol session (i.e., a PPP session), authentication can be performed through PAP or CHAP based on the user account information and password information obtained from the user terminal, and a PPP session can be established if the authentication is qualified, thereby authenticating the user terminal through PAP or CHAP, and preventing the user line information of the user terminal from being misused.

[0092] Optionally, after the PPP session is established, the session can be terminated through an active discovery termination message PADT.

[0098] In the above step S502, the access device may be a broadband remote access server BRAS.

[0100] In the above-mentioned embodiment of the present application, the user access port is the command input port of the access device. After the message replacement command is input into the user access port, the access device can use the device line information of the access device itself to replace the user line information carried in the target message of the discovery phase according to the message replacement command, thereby converting the target message of the discovery phase into the device message of the discovery phase, thereby realizing the determination of the message of the discovery phase.

[0101] Optionally, after obtaining the device message in the discovery phase, the method further includes: the device message in the discovery phase can be transmitted to a remote user dial-in authentication system RADIUS through a broadband remote access server BRAS for information matching.

[0102] Optionally, the message replacement command may be: “PPPoe intermediate-agent informationpolicy replace”.

[0103] The present invention also provides a preferred embodiment, which provides a method for realizing PPPoE+ dial-up Internet access and preventing fraudulent use on a personal terminal, mainly comprising: obtaining user line information, user account information and password information; constructing PADI messages and PADR messages according to the user line information, user account information and password information through the user terminal, and conducting a PPP session based on the negotiated PPP session connection parameters to realize direct dial-up Internet access.

[0104] This application constructs PADI messages and PADR messages directly through user terminals according to user lines, user account information, and password information, without the need for access equipment support, which can reduce the complexity of troubleshooting, testing, etc. and reduce manpower expenditures; secondly, the test can be performed through automation, and has no impact on the tested users during the test process, so the tested users can be unaware of it.

[0105] The technical solution provided in this application strips the PPPoE+ user line information transmitted from the user end through a broadband access device, re-inserts the PPPoE+ user line information generated by this device, and then transmits it to RADIUS through BRAS for information matching, thereby preventing the user line information of PPPoE+ from being stolen and improving user security.

[0106] Figure 6 Schematic diagram of a PPPoE+ protocol exchange process according to an embodiment of the present invention. Figure 6 As shown, a method for implementing PPPoE+ dial-up Internet access on a personal terminal and preventing fraudulent use mainly includes: PPPoE+ information input and acquisition module, PPPoE+ discovery phase module, PPPoE+ session phase module, PPPOE+ data transmission module, PPPOE+ session termination module, and a fraudulent use method, wherein the PPPoE+ information input and acquisition module, the PPPoE+ discovery phase module, the PPPoE+ session phase module, and the PPPOE+ data transmission module are installed on the personal terminal in the form of dial-up software.

[0107] Step 1. The PPPoE+ information input and acquisition module provides an input method for inputting and acquiring user line information, user account information, and password information. User account information and password information are used for PAP or CHAP authentication; user line information is used for the PPPoE+ discovery phase module to construct PPPoE+ data packets. The PPPoE+ data format is as follows: AccessNodeIdentifier / ANI_rack / ANI_frame / ANI_slot / ANI_subslot / ANI_port / ONU_ID.

[0108] Optionally, a character string of user line information in the following format is constructed according to the input information for backup: DeviceName / rack / frame / slot / subslot / port / 0000000000001A2B3C4D5E6F EP.

[0109] Step 2: PPPoE+ discovery phase module, using the information provided by the PPPoE+ information input and acquisition module (such as user line information).

[0110] A PADI is constructed at the user terminal, in which the destination address of the packet is 0×ffffffffffff, the CODE field value is 0×09, the SESSION-ID field value is 0×0000, the tag type field value is 0×0101, and a PPPoE tag (0×0105) is added, and the Value field of the PPPoE tag uses 0x000DE9 + the user line information of step 1.

[0111] Similarly, in the PADR information of the user terminal, the field value of CODE is 0×19, the field value of SESSION_ID is 0×0000, the PPPoE tag is added, and the user line information is filled in. The PPPoE+ data packet with added user line information is used to complete the discovery phase action of PADI-PADO-PADR-PADS, and SESSION_ID is written with the session identification number returned by PADS.

[0112] Step 3: The PPPoE+ session phase module conducts a PPP session according to the PPP session connection parameters negotiated in the discovery phase.

[0113] Optionally, all Ethernet frames are unicast. The SESSION-ID of the PPPoE+ session is based on the SESSION_ID of the PADS in the discovery phase, and the session communication is carried out. In the initiated PPP authentication, the PPPoE frame structure uses the user account information and password information obtained in step 2 to authenticate with the server through the PAP or CHAP protocol, completes the LCP transmission process, and completes the NCP transmission process of IP address allocation and MTU / MRU negotiation.

[0114] Optionally, the PPPOE+ data transmission module mainly utilizes a network interface driver to encapsulate data packets in Ethernet frames, transmits them on the network through network hardware, and decapsulates received Ethernet frames.

[0115] Optionally, the PPPOE+ session termination module is mainly used to terminate the PPPoE+ session, construct a PADT data packet, set the CODE field value to 0×a7, and the SESSION-ID field value to the SESSION-ID of the PPPoE+ session to be terminated, for dial-up termination.

[0116] Step 4: The user end adds access devices that support PPPoE+ through the above solution or through non-compliant methods, adds counterfeit PPPoE+ user line information, and transmits it to the broadband access device. To achieve the purpose of anti-counterfeiting, the broadband access device needs to strip the PPPoE+ user line information transmitted by the user end, re-insert the PPPoE+ user line information generated by the device, and then transmit it to RADIUS through BRAS for information matching to achieve the anti-counterfeiting function. Taking Huawei broadband access equipment as an example, execute the command "pppoe intermediate-agent information policy replace" on the user access port to replace the field format and content of the original PPPoE message information field.

[0117] The technical solution provided by the present application changes the PPPoE+ implementation method from intercepting the protocol message in the PPPoE discovery phase in the access device and inserting the user port information uplink to directly adding the user port information when constructing the PADI and PADR messages. This is more convenient and flexible, does not require the support of the access device, and the personal terminal can directly use PPPoE+ to implement dial-up Internet access, reducing the complexity of troubleshooting, testing, etc. and reducing manpower expenditure. The test can be performed automatically and has no impact on the tested user during the test, so that the tested user is unaware of it. In addition, the access device strips the PPPoE+ user line information transmitted from the user end and re-inserts the PPPoE+ user line information generated by the device to implement anti-counterfeiting work and improve user security.
