Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

Fig. 1 is a schematic topology diagram of a broadband networking scenario, and fig. 1 shows a broadband networking scenario of CPE and BRAS. The broadband networking scenario of the CPE and the BRAS includes the CPE 101, the upstream port device 102 and the BRAS 103. Wherein the upstream port device 102 is capable of communicating with the CPE 101 and BRAS 103, respectively.

Fig. 2 is a schematic topology diagram of yet another broadband networking scenario, and fig. 2 shows a broadband networking scenario of vCPE and vbas. CPE201, upstream port device 202, vce 203, and vbas 204 are included in a broadband networking scenario of vces and vbas. The upstream port device 202 can communicate with the CPE201 and the vce 203, respectively, and the vce 203 can communicate with the vbas 204.

In fig. 1 and 2, CPE 101 and CPE201 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, internet of things devices, and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart air conditioners, etc. The portable wearable device may be a smart watch, smart bracelet, headset, or the like.

The upstream port device 102 and the upstream port device 202 may include, but are not limited to, an optical line terminal (Optical Line Terminal, OLT) or a switch. The BRAS 103 may be implemented as a stand-alone server or as a cluster of servers.

The vces 203 and the vbas 204 are deployed in a cloud resource pool, for example, the vbas 204 includes a Control Plane (CP) and a forwarding Plane (User Plane, UP), and the vbas 204 is deployed in a centralized manner and adopts a CP cloud deployment and an UP pool deployment manner. It will be appreciated that vce 203 and vbas 204 may also be implemented as separate servers or as a cluster of servers.

Fig. 3 is an interaction schematic diagram of a broadband networking scenario, please combine fig. 1 and fig. 3, in the broadband networking scenario of CPE and BRAS, when a user needs to dial up, the CPE at the user side is used as a Client of PPPoE (Point-to-Point protocol over ethernet ), that is, the CPE is used as a PPPoE Client to dial up, and the BRAS is used as a Server of PPPoE, that is, the BRAS is used as a PPPoE Server.

In this process, the CPE will send a dial-up request to the BRAS to establish a PPPoE session between the CPE and the BRAS. The PPPoE session includes three phases. In the first Discovery (Discovery) stage, after the CPE sends a PADI (PPPoE Active Discovery Initiation) message to the BRAS and the OLT between the CPE and the BRAS intercepts the PADI message, physical information corresponding to the CPE is added to the PADI message in the form of a Tag.

After the BRAS returns the PADO (PPPoE Active Discovery Offer) message to the CPE, the CPE sends PADR (PPPoE Active Discovery Request) a message to the BRAS. Similarly, after the OLT between the CPE and the BRAS intercepts the PADE packet, physical information corresponding to the CPE is added to the PADR packet in the form of Tag.

Finally, the BRAS returns a PADS (PPPoE Active Discovery Session-confirmation) message to the CPE, thus completing the first discovery phase between the CPE and the BRAS and determining the unique post PPPoE session. In addition, in the process, the BRAS can acquire physical information corresponding to the CPE, and realize user tracing according to the physical information. And tracing the source of the user, namely acquiring information such as the position, the identity and the like of the CPE, and positioning the CPE.

Further, during the second session, PPP negotiation and data transmission can be performed between the CPE and the BRAS. Finally, in the third session termination stage, any party of the CPE and the BRAS may send PADT (PPPoE Active Discovery Termination) a message to end the PPPoE session.

In other words, in the broadband networking scenario, the upstream port device between the BRAS and the CPE can insert the physical information of the CPE into the access request, so that the BRAS completes the user tracing after obtaining the access request.

With the development of technology, the topology structure shown in fig. 2 is adopted in more and more broadband networking scenes. Fig. 4 is an interactive schematic diagram of another broadband networking scenario, please combine fig. 2 and fig. 4, in which a vCPE and a vbas generally fix dial-up resources first, and when a user needs to dial-up, the vCPE allocates resources to the user, for example, allocates addresses capable of surfing the internet to the CPE.

Thus, in a broadband networking scenario of vces and vbas, the vbas acts as PPPoE server, while the vces act as PPPoE clients. That is, a PPPoE session between the vCPE and the vbas is typically established first, and then a session between the user and the vCPE, that is, a session between the CPE and the vCPE is established again. Thus, the vCPE will initiate a dial-up request to the vcbras to complete the discovery phase and session phase between the vCPE and the vcbras, and complete the session termination phase without requiring a connection.

When a user needs to dial-up between the CPE and the vCPE, the CPE initiates DHCP (Dynamic Host Configuration Protocol) a dial-up Request to the vCPE, and completes four processes of discovery (Discover), provisioning (Offer), request (Request) and acknowledgement (Reply) to allocate an address to the CPE by the vCPE.

The OLT between the CPE and the vCPE may intercept the discovery packet and the request packet, and carry the physical information of the CPE through the Option82 of DHCP (DHCP relay agent information Option, relay Agent Information Option) in the discovery packet and the request packet, so that the vCPE obtains the physical information of the CPE. However, since the DHCP dialing of the user is later than the PPPoE Discovery phase, that is, since the interaction process between the CPE and the vCPE is later than the Discovery phase between the vCPE and the vbas, when the CPE performs the DHCP dialing, the vCPE and the vbas are already in the session phase, in the broadband networking scenario of the vCPE and the vbas, the physical information of the CPE cannot be sent to the vbas in the Discovery phase, and thus the vbas cannot realize the tracing of the user.

Based on this, it is necessary to provide an information processing method capable of implementing user tracing in a broadband networking scenario of vces and vbas, and the information processing method will be described below. The information processing method provided by the embodiment of the application can be applied to an application environment shown in fig. 2.

Fig. 5 is a flow chart of an information processing method according to an embodiment of the present application, which can be applied to the vCPE shown in fig. 1, and in an embodiment, as shown in fig. 5, the method includes the following steps:

S501, a dialing request sent by the line-up port equipment is received in a session stage; the dialing request carries the physical information of the user equipment.

In this embodiment, in the broadband networking scenario of the vCPE and the vbas, when the user needs to dial-up to access the network, the CPE sends a DHCP-based dial-up request to the vCPE.

Referring to fig. 4, after the CPE initiates a DHCP-based dialing request to the vCPE, taking an OLT as an example of an upstream port device between the CPE and the vCPE, the OLT may add physical information of the user equipment to the dialing request, for example, add the Option82 to a discover message and an offer message. Therefore, the vCPE can receive the dialing request carrying the physical information of the user equipment sent by the upstream port device.

The physical information of the ue may be, but is not limited to, a slot number, a daughter card number, an interface number, a VLAN (virtual local area network ), and a MAC address (media access control address, media Access Control Address) corresponding to the CPE.

S502, mapping the physical information to the first session message to obtain a second session message.

In this embodiment, after receiving a dialing request sent by the upstream port device, the vCPE determines the carried physical information from the dialing request, and maps the physical information to a session packet to be sent to the vbas, so as to obtain a second session packet.

Alternatively, the vCPE may store a mapping relationship between the dialing request and the first session packet, where the mapping relationship may be defined in advance in the vCPE.

Further alternatively, the vCPE may add physical information at a designated location in the first session message, thereby obtaining the second session message, e.g., the vCPE may add physical information at the end of the first session message.

For example, in connection with fig. 4, the vCPE may add physical information as Tag information to a packet during data transmission between the vCPE and the vbas, that is, to a packet in the session phase based on PPPoE.

And S503, the second session message is sent to the virtual broadband access server vBRAS.

Further, the vbas may send the second session packet to the vbas, so that the vbas performs user tracing according to the received second session packet.

According to the information processing method provided by the embodiment, after the vCPE receives the dialing request sent by the upstream port device in the session stage, the physical information of the user equipment is carried in the dialing request, so that the vCPE can map the physical information into the first session message to obtain the second session message, and after the second session message is sent to the virtual broadband access server vBRAS, the vBRAS can perform user tracing based on the physical information in the second session message, and therefore the user tracing in the broadband networking scene of the vCPE and the vBRAS is realized without changing the architecture of the vCPE and the vBRAS in the broadband networking scene.

In one embodiment, optionally, the step S502 of mapping the physical information to the first session packet to obtain the second session packet may be implemented as follows:

mapping the physical information into a first session message according to the mapping relation sent by the controller to obtain a second session message; the mapping relation comprises a corresponding relation between the dialing request and the first session message.

Fig. 6 is a schematic topology diagram of a broadband networking scenario in an embodiment of the present application, as shown in fig. 6, in the broadband networking scenario of vCPE and vbas, a controller may be further configured, where the controller may communicate with the CPE, the upstream port device, the vCPE and the vbas, respectively, so that the controller issues a control policy or configured parameters.

In this embodiment, please continue to refer to fig. 4, the communication between the cpe and the vCPE is based on DHCP, and the communication between the vCPE and the vbas is based on PPPoE, so, in order to be able to map the physical information to the first session message, the controller sends the mapping relation to the vCPE. The mapping relationship comprises a corresponding relationship between the dialing request and the first session message.

For example, the mapping relationship includes a correspondence between the Option82 of DHCP and PPPoE, so after the vCPE receives the dialing request sent by the CPE, the physical information of the user equipment may be determined from the Option82 of the dialing request, and then the physical information is added to the first session message in the session stage based on PPPoE.

Optionally, the controller may send the mapping relationship to the vCPE before the CPE needs to send the dialing request, or may send the mapping relationship to the vCPE while the CPE sends the dialing request or after the CPE sends the dialing request.

In this embodiment, the mapping relationship includes a correspondence relationship between the dialing request and the first session packet, and the controller may send the mapping relationship to the vCPE, so after receiving the first session packet, the controller may map the physical information to the first session packet to obtain the second session packet, thereby implementing user tracing.

In one embodiment, optionally, the above-mentioned "mapping the physical information to the first session packet according to the mapping relationship sent by the controller to obtain the second session packet" may be implemented by:

In this embodiment, in the process of obtaining the second session packet, the vCPE actually expands the load field of the first session packet according to the mapping relationship, and adds the physical information to the expansion field. For example, assuming that the payload field of the original first session message is 32 bits in total, the vCPE may extend the payload field of the first session message back to 40 bits and add the physical information to the extended 8 bits.

According to the embodiment, the load field of the first session message is expanded according to the mapping relation, and the physical information is added into the expansion field to obtain the second session message. Therefore, the physical information is added into the second session message, and the user tracing is realized.

In one embodiment, optionally, the frame format of the second session packet includes a header and a payload field, and the payload field includes physical information.

In this embodiment, the frame format of the second session packet includes a packet header and a payload field. The header is used for reflecting necessary information carried by the message, and may include, for example, a unique ID (identity, identity document) of session. The payload field is used to carry the data that needs to be transmitted. In this embodiment, the load field of the first session packet is extended, so that the load field of the second session packet includes physical information. For example, the physical information includes a field 1 for recording the MAC address of the user equipment, and a field 2 for recording the VLAN of the user equipment.

In this embodiment, the frame format of the second session packet includes a packet header and a load field, and because the load field includes physical information, the load field of the first session packet is extended, and the physical information can be added to the load field of the first session packet.

In one embodiment, the physical information optionally includes a flag bit field, a reserved field, a length field, and a data field.

In this embodiment, the physical information includes a Flag bit field Tag Flag, a reserved field Reserve, a Length field Tag Length, and data fields Tag 1 to Tag N.

Fig. 7 is a schematic diagram of a frame format of a second session packet according to an embodiment of the present application, where, as shown in fig. 7, the first session packet includes a header and a payload field.

The header in the first Session packet may include "access_concentrator_mac_address" and "access_concentrator_mac_ address (Continue)" for representing the MAC address of the accessed Concentrator, "host_mac_address" and "host_mac_ address (Continue)" for representing the MAC address of the accessed Host, i.e., the "ethernet_type" of the protocol of the frame data field, the "v=1" for representing the version identification, "t=1" for representing the block transmission protocol, "Code" for representing the PPPoE packet Type of the packet, "session_id" for representing the Session identification, "Length" for identifying the Length of the packet.

Further, the first session message also includes a Payload field "Payload". In this embodiment, the vCPE inserts physical information in the form of a Tag in the middle of the Payload field "Payload". With continued reference to fig. 6, the physical information includes a Flag bit field Tag Flag, a reserved field Reserve, a Length field Tag Length, and data fields Tag 1 to Tag N.

The Flag field Tag Flag is used for marking whether the second session message carries physical information. In one embodiment, optionally, if the flag bit field is the first value, it indicates that the second session packet includes physical information; and if the flag bit field is a second value, the second session message does not include physical information.

For example, if the flag bit field is 1, it indicates that the second session packet includes physical information; if the flag bit field is 1, it indicates that the second session packet does not include physical information. Therefore, whether the second session message carries physical information or not can be marked through the flag bit field, so that the physical information does not need to be added in each first session message, and occupation of transmission broadband is reduced.

The reserved field Reserve facilitates subsequent extension of physical information in the second session message.

The Length field Tag Length is used for indicating the Length of the physical information, so that whether the physical information is complete or not is ensured according to the Length field Tag Length after the vbas receives the second session message.

The data fields Tag 1 to Tag N are used to carry detailed physical information, N is an integer greater than or equal to 1, for example Tag 1 represents "MAC address", tag 1 represents "VLAN", tag3 represents "slot number", and so on.

In this way, after receiving the dialing request, the vCPE can determine the physical information in the option82, and fill the Flag bit field Tag Flag, the reserved field Reserve, the Length field Tag Length, and the data fields Tag1 to Tag N in the extension field of the load field of the first session packet according to the physical information in the option82, so as to obtain the second session packet.

It will be appreciated that the foregoing illustrates an alternative form of the second session message, and that in some embodiments, the header in the second session message may include other fields, and the physical information may be located anywhere in the payload field.

In this embodiment, the physical information includes a flag bit field, a reserved field, a length field and a data field, so that adding physical information in a first session packet for data transmission is realized, and an existing protocol is extended to realize user tracing without changing a networking mode.

The above describes the process of the information processing method running on the vCPE side, and the following describes the process of the information processing method running on the vbas side. Fig. 8 is a flow chart of another information processing method according to an embodiment of the present application, which can be applied to the vbas shown in fig. 1, and in one embodiment, as shown in fig. 8, the method includes the following steps:

S801, receiving a second session message sent by the vCPE in a session stage; and the second session message is obtained by mapping the physical information of the user equipment carried in the dialing request to the first session message under the condition that the vCPE receives the dialing request sent by the upstream port equipment.

In this embodiment, the same principle as S401 to S403, when a user wants to dial up in a broadband networking scenario of a vCPE and a vbas, the CPE will send a DHCP-based dial-up request to the vCPE. After the upstream port device between the CPE and the vCPE intercepts the dialing request, the physical information of the user device may be added to the dialing request. For example, the OLT adds the Option82 to discover messages and offer messages.

After the vCPE acquires the dialing request, the physical information of the user equipment may be determined from the dialing request. Further, the vCPE maps physical information of the user equipment carried in the dialing request to the first session message, so as to obtain a second session message.

The process of mapping the physical information to the first session packet by the vCPE to obtain the second session packet may refer to the above embodiment, and will not be described herein again.

Thus, referring to fig. 4, in the session phase of vCPE and vbas based on PPPoE, that is, in the session phase, the vbas may receive the second session packet sent by vCPE. And the second session message carries the physical information of the user equipment.

S802, user tracing is carried out according to physical information in the second session message.

Further, after receiving the second session message, the vbas may perform user tracing according to physical information in the second session message. The physical information includes, but is not limited to, a slot number, a sub-card number, an interface number, a VLAN, and a MAC address corresponding to the CPE.

According to the information processing method provided by the embodiment, the second session message is obtained by mapping the physical information of the user equipment carried in the dialing request to the first session message under the condition that the vCPE receives the dialing request sent by the upstream port device, so that the vBRAS receives the second session message sent by the vCPE in the session stage, and user tracing can be performed according to the physical information in the second session message. Therefore, the user tracing in the broadband networking scene of the vCPE and the vBRAS is realized without changing the architecture of the vCPE and the vBRAS in the broadband networking scene.

In this embodiment, please continue with fig. 7, the vcpe will add physical information in the payload field. Therefore, the expansion of the load field of the first session message is realized, so that the physical information can be added into the load field of the first session message.

With continued reference to fig. 7, the physical information includes a Flag bit field Tag Flag, a reserved field Reserve, a Length field Tag Length, and data fields Tag 1 to Tag N.

In one embodiment, optionally, if the flag bit field is the first value, it indicates that the second session packet includes physical information; and if the flag bit field is a second value, the second session message does not include physical information.

The description of the Flag bit field Tag Flag, the reserved field Reserve, the Length field Tag Length, and the data fields Tag 1 to Tag N refer to the above embodiments, and will not be repeated here.

In this embodiment, the physical information includes a flag bit field, a reserved field, a length field and a data field, so that it is realized that physical information is added in a first session packet for data transmission, and the existing protocol is extended to realize user tracing without changing the networking mode.

In order to more clearly describe the information processing method in the present application, it is described with reference to fig. 9. Fig. 9 is an interaction schematic diagram of an information processing method in an embodiment of the present application, as shown in fig. 9, in an embodiment, a Discovery phase based on PPPoE is performed between vCPE and vbas, and a user does not need to dial-up.

Under the condition that a user needs to dial-up and surfing the internet, a CPE at the user side initiates a dialing request based on DHCP to a vCPE, and further, an upstream port device, such as an OLT, between the CPE and the vCPE intercepts the dialing request, and Option 82 is added in the dialing request so as to carry physical information of the user equipment in the dialing request.

Further, after the vCPE receives the Discover message carrying the physical information, the physical information in the Discover message is mapped to a first session message based on PPPoE with the vbas, so as to obtain a second session message. In this way, in the session stage of the vCPE and the vbas, the vCPE sends a second session message with a Tag Flag bit field of 1 to the vbas, and Tag 1 to Tag N carry physical information of the user equipment. Therefore, after receiving the second session message, the vBRAS can realize user tracing.

Further, the CPE continues to complete the DHCP-based dialing process with the vCPE to obtain the address assigned by the vCPE. When the vCPE and the vbas do not need to establish the PPPoE session, any one of the vCPE and the vbas can terminate the PPPoE session.

In this process, the vCPE as the PPPoE Client can add physical information including a flag bit field, a reserved field, a length field, and a data field to the first session message in the session stage of PPPoE according to the mapping relationship between the dialing request and the first session message when receiving the message carrying the Option 82, that is, when receiving the dialing request carrying the physical information, so as to obtain the second session message. Therefore, after receiving the second session message, the vbas can realize user tracing according to the physical information therein. The above process may also refer to the above embodiment, and will not be described herein.

It should be understood that, although the steps in the flowcharts related to the embodiments described above are sequentially shown as indicated by arrows, these steps are not necessarily sequentially performed in the order indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in the flowcharts described in the above embodiments may include a plurality of steps or a plurality of stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of the steps or stages is not necessarily performed sequentially, but may be performed alternately or alternately with at least some of the other steps or stages.

Based on the same inventive concept, the embodiment of the application also provides an information processing device for realizing the above-mentioned related information processing method. The implementation of the solution provided by the device is similar to the implementation described in the above method, so the specific limitation of one or more embodiments of the information processing device provided below may refer to the limitation of the information processing method hereinabove, and will not be repeated herein.
