Description

Technical Field

[0001] This application relates to the field of network communication technology, and in particular to a method and apparatus for automatically identifying ports. Background Technology

[0002] Internet Protocol Television (IPTV) data pass-through refers to the direct forwarding of IPTV data packets transmitted between the set-top box (STB) and the optical modem without any processing. These IPTV data packets include both uplink data packets transmitted from the optical modem to the STB (i.e., data packets transmitted from the WAN port (iTV port) connected to the IPTV port of the optical modem to the LAN port (STB port) connected to the STB) and downlink data packets transmitted from the STB to the optical modem (i.e., data packets transmitted from the STB port to the iTV port).

[0003] Currently, to achieve IPTV data pass-through, it is first necessary to identify the iTV port (IPTV port) of the router's uplink connection to the optical modem and the STB port (STB) of the router's downlink connection. Then, a virtual local area network (VLAN) is established to achieve lossless pass-through of IPTV data packets between the iTV port and the STB port. There are two existing methods for identifying the iTV port: one is to designate a fixed WAN-side port as the iTV port via the router, and the other is to select any LAN-side port as the iTV port through manual user configuration. The existing method for identifying the STB port is mainly through manual user configuration. However, manual configuration increases the difficulty of use for users, resulting in a poor user experience.

[0004] It is evident that the existing IPTV data pass-through method requires users to manually configure the router's iTV port and STB port, resulting in a poor user experience. Summary of the Invention

[0005] This application provides a method and apparatus for automatically identifying ports to solve the technical problem that existing IPTV data pass-through requires users to manually configure the port selection for connecting the optical modem and set-top box, resulting in a poor user experience.

[0006] In a first aspect, embodiments of this application provide a method for automatically identifying ports, applied to routing, wherein the routing is the main route of a distributed Internet Protocol Television (IPTV) system or any route of a non-distributed IPTV system, the method comprising:

[0007] Receive the first data stream sent by the set-top box and determine whether the first data stream is an IPTV data stream;

[0008] If the first data stream is determined to be an IPTV data stream, then the LAN port receiving the first data stream is determined to be the first port, and when it is determined that only Internet access data stream and IPTV data stream are received, the Dynamic Host Configuration Protocol (DHCP) or the Point-to-Point Protocol (PPPoE) server on Ethernet is turned off. The first port is a LAN port connected to the set-top box through a first sub-router or directly connected to the set-top box, and the first sub-router is any sub-router of the distributed IPTV system.

[0009] If a DHCP or PPPoE response message is received from the IPTV server, the LAN-side port that receives the DHCP or PPPoE response message is determined to be the second port, wherein the second port is the WAN-side port connected to the IPTV port of the optical modem.

[0010] The first data stream is sent to the optical modem via the second port.

[0011] Based on the above technical solution, the main router of the distributed IPTV system or any router of the non-distributed IPTV system can receive the first data stream sent by the set-top box and determine whether the first data stream is an IPTV data stream. If the first data stream is determined to be an IPTV data stream, the LAN-side port receiving the first data stream is designated as the first port. When it is determined that only Internet data streams and IPTV data streams are received, the DHCP or PPPoE server is turned off. The first port is the LAN-side port connected to the set-top box through the first sub-router or directly connected to the set-top box. The first sub-router is any sub-router of the distributed IPTV system. If a DHCP or PPPoE response message is received from the IPTV server, the LAN-side port receiving the DHCP or PPPoE response message is designated as the second port. The second port is the WAN-side port connected to the IPTV port of the optical modem. Based on the second port, the first data stream is sent to the optical modem. By identifying IPTV data streams, the system identifies the LAN-side ports connected to the set-top box via the first sub-router or directly to the set-top box. It also identifies the WAN-side ports connected to the IPTV port of the optical modem by recognizing DHCP or PPPoE response messages. This avoids the need for manual user configuration to select the ports connecting the optical modem and set-top box, and eliminates the need to rely on the option60 field in DHCP uplink messages for automatic identification of these ports. Furthermore, it eliminates the need to pre-obtain the STB vendor list used for client OUI matching to automatically identify the ports connecting the optical modem and set-top box, thus improving user experience and covering all STB usage scenarios.

[0012] In one possible design, determining whether the first data stream is an IPTV data stream includes:

[0013] Determine whether the first data stream carries IPTV characteristics;

[0014] If it is determined that the first data stream carries the IPTV characteristics, then the first data stream is determined to be an IPTV data stream.

[0015] In one possible design, before sending the first data stream to the optical modem via the second port, the following steps are also included:

[0016] Determine the first VLAN tag corresponding to the first port and the second VLAN tag corresponding to the second port;

[0017] Based on the first VLAN tag and the second VLAN tag, update the VLAN tag conversion table, wherein the updated VLAN tag conversion table includes the correspondence between the first VLAN tag and the second VLAN tag;

[0018] Based on the updated VLAN tag conversion table, the first data stream is subjected to VLAN tag conversion processing.

[0019] In one possible design, based on the updated VLAN tag conversion table, VLAN tag conversion processing is performed on the first data stream, including:

[0020] The first data stream is subjected to tag removal processing, and the first data stream after tag removal processing is sent to the second port, wherein the tag removal processing is used to remove the first VLAN tag carried by the first data stream;

[0021] Based on the updated VLAN tag conversion table, a tag creation process is performed on the first data stream after the tag deletion process on the second port, wherein the first data stream after the tag creation process carries the second VLAN tag.

[0022] In one possible design, after updating the VLAN tag translation table based on the first VLAN tag and the second VLAN tag, the following steps are also included:

[0023] Determine whether the connection between the first port and the set-top box has been disconnected;

[0024] If the connection has been broken, the mapping between the first VLAN tag and the second VLAN tag will be deleted from the updated VLAN tag conversion table.

[0025] Receive the second data stream sent by the set-top box and determine whether the second data stream is an IPTV data stream;

[0026] If the second data stream is determined to be an IPTV data stream, then the LAN-side port receiving the second data stream is determined to be the third port. The third port is a LAN-side port that is connected to the set-top box through the second sub-route or directly connected to the set-top box. The second sub-route is any sub-route of the distributed IPTV system other than the first sub-route.

[0027] Create a mapping relationship between the third VLAN tag and the second VLAN tag in the updated VLAN tag conversion table, wherein the third VLAN tag is the VLAN tag corresponding to the third port.

[0028] In one possible design, determining whether the connection between the first port and the set-top box has been broken includes:

[0029] If it is determined that the storage time of the media access control MAC address of the set-top box stored in the forwarding database FDB is greater than a first preset threshold, then it is determined that the connection between the first port and the set-top box has been broken; or,

[0030] If the time after sending an Address Resolution Protocol (ARP) message to the set-top box without receiving a reply from the set-top box exceeds a second preset threshold, then it is determined that the connection between the first port and the set-top box has been broken; or,

[0031] If the routing driver detects that the physical link is broken, it determines that the connection between the first port and the set-top box has been broken.

[0032] Based on the above technical solution, the main router of the distributed IPTV system or any router of the non-distributed IPTV system can determine whether the connection between the first port and the set-top box has been disconnected. If it has been disconnected, the correspondence between the first VLAN tag and the second VLAN tag is deleted in the updated VLAN tag conversion table. The second data stream sent by the set-top box is received, and it is determined whether the second data stream is an IPTV data stream. If the second data stream is determined to be an IPTV data stream, the LAN-side port receiving the second data stream is determined to be the third port. The third port is the LAN-side port connected to the set-top box through the second sub-route or directly connected to the set-top box. The second sub-route is any sub-route of the distributed IPTV system other than the first sub-route. A correspondence between the third VLAN tag and the second VLAN tag is created in the updated VLAN tag conversion table. The third VLAN tag is the VLAN tag corresponding to the third port. When the connection between the first port and the set-top box is determined to be broken, the LAN-side port connected to the set-top box via the second sub-router or directly to the set-top box is re-identified. The mapping relationship between the VLAN tag corresponding to the re-identified LAN-side port and the second VLAN tag is created in the VLAN tag conversion table. This enables IPTV data pass-through and avoids the problem of needing to rebind the port after changing the port connected to the set-top box and the router. It is plug-and-play and improves the user experience.

[0033] Secondly, this application also provides an apparatus for automatically identifying ports. This apparatus has the function of implementing the first aspect or any possible design method described in the first aspect.

[0036] The second processing module is used to determine the LAN port receiving the DHCP or PPPoE response message as the second port if it receives the DHCP or PPPoE response message sent by the IPTV server. The second port is the WAN port connected to the IPTV port of the optical modem.

[0070] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0071] To better understand the technical solutions provided in the embodiments of this application, the technical terms involved in the embodiments of this application will be explained below.

[0072] I. Data Transmission for Internet Protocol Television (IPTV)

[0073] IPTV data pass-through refers to the direct forwarding of IPTV data packets transmitted between the set-top box (STB) and the optical modem without any processing, via a router. These IPTV data packets include both uplink data packets from the optical modem to the STB (i.e., data packets transmitted from the WAN (Internet Protocol) port (iTV port) connected to the optical modem's IPTV port to the LAN (Local Area Network) port (STB port) connected to the STB), and downlink data packets from the STB to the optical modem (i.e., data packets transmitted from the STB port to the iTV port). The router can be the main router of a distributed IPTV system or any router in a non-distributed IPTV system.

[0074] For example, such as Figure 1a The diagram shown is a schematic representation of an IPTV data pass-through method provided in an embodiment of this application. Figure 1a The IPTV system in this example is a non-distributed IPTV system, consisting of only one router. The router has two WAN-side ports (WAN port and iTV port) and multiple LAN-side ports (LAN1, LAN2, LAN3, LAN4, ..., LANX). The WAN port connects to the optical modem's internet port via an uplink network cable and is used to transmit ordinary internet data packets. The iTV port connects to the optical modem's IPTV port via an uplink network cable and is used to transmit IPTV data packets, thus forming a dual-WAN uplink network. The LAN3 port connects to the STB's network port via a downlink network cable and is used to transmit IPTV data packets; therefore, the router's LAN3 port can be referred to as the STB port. During IPTV data pass-through, the uplink data packets from the optical modem to the STB are transmitted via: optical modem's IPTV port → router's iTV port → router's LAN3 port → STB's network port. The downlink data packets from the STB to the optical modem are transmitted via: STB's network port → router's LAN3 port → router's iTV port → optical modem's IPTV port.

[0075] For example, such as Figure 1b The diagram shown is a schematic representation of another IPTV data pass-through method provided in an embodiment of this application. Figure 1bThe IPTV system in this example is a distributed IPTV system, consisting of a main router (i.e., an access point controller (AC)) and multiple sub-routers (i.e., access points (APs)). The main router AC has two WAN-side ports: a WAN port and an iTV port, and multiple LAN-side ports: LAN1, LAN2, LAN3, LAN4, ..., LANX. The WAN port connects to the optical modem's internet port via an uplink network cable and is used to transmit ordinary internet data packets. The iTV port connects to the optical modem's IPTV port via an uplink network cable and is used to transmit IPTV data packets, thus forming a dual-WAN uplink network. Each sub-router AP connects to the main router AC's LAN-side ports via an uplink network cable and to the STB's network port via a downlink network cable. For example, if sub-router AP3 connects to the main router AC's LAN3 port via an uplink network cable and to the STB's network port via a downlink network cable, then the main router AC's LAN3 port can be referred to as the STB port. When performing IPTV data pass-through, the transmission route of uplink data packets from the optical modem to the STB is as follows: IPTV port of the optical modem → iTV port of the main router AC → LAN3 port of the main router AC → AP3 of the sub-router → network port of the STB. The transmission route of downlink data packets from the STB to the optical modem is as follows: network port of the STB → AP3 of the sub-router → LAN3 port of the main router AC → iTV port of the main router AC → IPTV port of the optical modem.

[0076] Therefore, to achieve IPTV data pass-through, it is first necessary to identify the iTV port (IPTV port) of the router's uplink connection to the optical modem and the STB port (network port) of the router's downlink connection to the STB. Then, a virtual local area network (VLAN) is established to achieve lossless pass-through of IPTV data packets between the iTV port and the STB port. There are currently two methods for identifying the iTV port: one is to designate a fixed WAN-side port as the iTV port via the router, and the other is to select any LAN-side port as the iTV port through manual user configuration. The existing method for identifying the STB port is mainly through manual user configuration. However, manual configuration increases the difficulty of use for users, resulting in a poor user experience.

[0077] 2. Automatically identify the router's iTV port and STB port.

[0078] (1) The router parses the Option60 field in the Dynamic Host Configuration Protocol (DHCP) message sent by the client (Internet client and IPTV client), and determines the service type of the client's Medium Access Control (MAC) based on the parsed field information, thereby identifying the STB's information flow. Specifically, if the field information contains a SCITV field or an encrypted field containing @ITV, then the client's MAC is of IPTV type; otherwise, the client's MAC is of Internet type. If the client's MAC is of IPTV type, then the data flow sent by the client is transferred to the IPTV VLAN channel. For example, the router receives the data flow sent by the client through the STB port of the downlink network port connected to the STB, and forwards the data flow sent by the client through the iTV port of the IPTV port connected to the optical modem uplink. Otherwise, the data flow of the client's MAC is transferred to the Internet VLAN channel. For example, the router receives the data flow sent by the client through the LAN port of the downlink network port connected to the client, and forwards the data flow sent by the client through the WAN port of the Internet port connected to the optical modem uplink. However, this technical solution relies on the option60 field in the DHCP message to automatically identify the iTV port and STB port of the route. If the client sends a point-to-point protocol over Ethernet (PPPoE) message, it will not be able to automatically identify the iTV port and STB port of the route, resulting in the inability to cover all STB usage scenarios.

[0079] (2) When a client (Internet client and IPTV client) is connected to any port of the router, the router will automatically search for the client's Organizationally Unique Identifier (OUI) in the STB vendor list of any STB connected to the router. If the STB matches the client, the port will be automatically marked as the iTV port of the router's uplink connection to the optical modem's IPTV port. If the STB does not match the client, the port will be automatically marked as the WAN port of the router's uplink connection to the optical modem's Internet port. However, when automatically identifying the router's iTV port and STB port through the STB vendor list, the STB vendor list used to match the client's OUI must be obtained in advance. Furthermore, if the OUIs in the STB vendor list are incomplete, the corresponding client cannot be identified, thus failing to cover all STB usage scenarios.

[0080] Therefore, existing IPTV data pass-through methods either fail to automatically identify the router's iTV and STB ports, requiring manual configuration by the user, resulting in a poor user experience; or rely on the option60 field in DHCP uplink packets for automatic identification, which cannot be done with PPPoE uplink packets, thus failing to cover all STB usage scenarios; or require obtaining a list of STB vendors for matching client OUIs in advance, but if the OUIs in the STB vendor list are incomplete, the corresponding client cannot be identified, again failing to cover all STB usage scenarios.

[0081] In view of this, embodiments of this application provide a method for automatically identifying ports. This method can receive a first data stream sent by a set-top box and determine whether the first data stream is an IPTV data stream. If the first data stream is determined to be an IPTV data stream, the LAN-side port receiving the first data stream is determined to be the first port. When it is determined that only Internet data streams and IPTV data streams are received, the DHCP or PPPoE server is turned off. The first port is a LAN-side port connected to the set-top box through a first sub-router or directly connected to the set-top box. The first sub-router is any sub-router of the distributed IPTV system. If a DHCP or PPPoE response message is received from an IPTV server, the LAN-side port receiving the DHCP or PPPoE response message is determined to be the second port. The second port is a WAN-side port connected to the IPTV port of the optical modem. Based on the second port, the first data stream is sent to the optical modem. By identifying IPTV data streams, the system identifies the LAN-side ports connected to the set-top box via the first sub-router or directly to the set-top box. It also identifies the WAN-side ports connected to the IPTV port of the optical modem by recognizing DHCP or PPPoE response messages. This avoids the need for manual user configuration to select the ports connecting the optical modem and set-top box, and eliminates the need to rely on the option60 field in DHCP uplink messages for automatic identification of these ports. Furthermore, it eliminates the need to pre-obtain the STB vendor list used for client OUI matching to automatically identify the ports connecting the optical modem and set-top box, thus improving user experience and covering all STB usage scenarios.

[0082] It should be understood that the technical solutions of the embodiments of this application can be applied to various systems that automatically identify ports. For example... Figure 2The diagram shown is a structural schematic of an automatic port identification system provided in an embodiment of this application. The automatic port identification system includes an optical modem 201, an IPTV system 202, and an STB 203. The IPTV system 202 can be a non-distributed IPTV system 202 or a distributed IPTV system 202. This embodiment of the application does not make specific limitations on this.

[0083] If IPTV system 202 is a distributed IPTV system 202, then IPTV system 202 includes a router 2020. Router 2020 has two WAN-side ports, namely the WAN port and the iTV port, and multiple LAN-side ports, namely LAN1 port, LAN2 port, LAN3 port, LAN4 port, ..., LANX port. The WAN port is connected to the Internet access port of optical modem 201 via an uplink network cable and is used to transmit ordinary Internet access data packets. The iTV port is connected to the IPTV port of optical modem 201 via an uplink network cable and is used to transmit IPTV data packets. The LAN3 port is connected to the network port of STB203 via an offline network cable and is used to transmit IPTV data packets. Therefore, the LAN3 port of router 2020 is the STB port of router 2020.

[0084] If IPTV system 202 is a distributed IPTV system 202, then IPTV system 202 includes a main router AC and multiple sub-routers AP, namely AC2020 and AP2021, AP2022, AP2023, AP2024, ..., AP202X. AC2020 has two WAN-side ports, namely the WAN port and the iTV port, and multiple LAN-side ports, namely LAN1, LAN2, LAN3, LAN4, ..., LANX. The WAN port connects to the optical modem's internet port via an uplink network cable and is used to transmit ordinary internet data packets. The iTV port connects to the optical modem's IPTV port via an uplink network cable and is used to transmit IPTV data packets. Each AP connects to the AC's LAN-side ports via an uplink network cable, such as AP2021 connecting to the AC's LAN1 port, AP2022 connecting to the AC's LAN2 port, AP2023 connecting to the AC's LAN3 port, AP2024 connecting to the AC's LAN4 port, ..., AP2020... The X port is connected to the LAN X port of the AC. Each AP connects to the STB port via the network cable. For example, if AP2023 connects to the STB203 port via the network cable, then the LAN3 port of AC2020 is the STB port of AC2020.

[0085] The above describes the automatic port identification system to which the technical solutions of the embodiments of this application can be applied. The following describes an automatic port identification method provided by the embodiments of this application in conjunction with the accompanying drawings.

[0086] It should be understood that "at least one" in the embodiments of this application refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a and b and c.

[0087] Furthermore, unless otherwise stated, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority, or importance of multiple objects. For example, the first priority criterion and the second priority criterion are only used to distinguish different criteria, and do not indicate that the content, priority, or importance of these two criteria are different.

[0088] like Figure 3 The diagram shown is a flowchart illustrating an automatic port identification method provided in an embodiment of this application. This automatic port identification method can be applied to the above-mentioned... Figure 2 The shown or the Figure 2 On systems with similar functional structures that automatically identify ports, the specific process of this automatic port identification method is described below.

[0089] S301. Receive the first data stream sent by the set-top box and determine whether the first data stream is an IPTV data stream.

[0090] In some embodiments, a user can connect the set-top box to any port of the IPTV system. If the IPTV system is a distributed IPTV system, the set-top box can be connected to any sub-router of the distributed IPTV system. For example, STB203 can be connected to AP2023 of the distributed IPTV system 202, that is, AP2023 is a directly connected route of STB203. If the IPTV system is a non-distributed IPTV system, the set-top box can be connected to any port of the non-distributed IPTV system. For example, STB203 can be connected to the LAN3 port of route 2020 of the non-distributed IPTV system 202, that is, route 2020 is a directly connected route of STB203. After the set-top box is powered on, it sends a first data stream to the main router of the distributed IPTV system or any router of the non-distributed IPTV system. The main router of the distributed IPTV system or any router of the non-distributed IPTV system receives the first data stream sent by the set-top box and determines whether the first data stream is an IPTV data stream. For example, it determines whether the first data stream carries IPTV characteristics. IPTV characteristics include IPTV resource paths, IPTV reference information, IPTV verification domain names, IPTV video stream addresses or IPTV request messages, as well as basic data characteristics such as data length, protocol type, port number, multicast messages, DHCP interaction messages, etc. This application embodiment does not make specific limitations on this. If it is determined that the first data stream carries IPTV characteristics, then the first data stream is determined to be an IPTV data stream.

[0091] For example, STB203 sends an HTTP GET request message to AC2020 of distributed IPTV system 202 or router 2020 of non-distributed IPTV system 202. The HTTP GET request message carries the resource path / iptvepg / platform / index.jsp. AC2020 of distributed IPTV system 202 or router 2020 of non-distributed IPTV system 202 determines that the resource path is an IPTV resource path, and thus determines that the HTTP GET request message is an IPTV message.

[0092] STB203 sends an HTTP POST request message to AC2020 of the distributed IPTV system 202 or Router 2020 of the non-distributed IPTV system 202. The reference information of this HTTP POST request message is Referer:http: / / 121.60.255.6:8080 / iptvepg / platform / index.jsp?UserID=wh1810161569&Action=Login&FCCSupport=1\r\n. AC2020 of the distributed IPTV system 202 or Router 2020 of the non-distributed IPTV system 202 determines that this reference information is IPTV reference information, and thus determines that this HTTP POST request message is an IPTV message.

[0093] STB203 sends a Domain Name Server (DNS) request message to AC2020 of the distributed IPTV system 202 or Router 2020 of the non-distributed IPTV system 202. This DNS request message requests the resolution of the addresses scs.openspeech.cn and appstorerrc.jjc.cnitv.net. Since commonly used IPTV verification domains include: eds.gx.vnet.cn, data.openspeech.cn, appstorerrc.jjc.cnitv.net, schemas.upnp.org, stb.gx.mihua.tv, api.cloud.189.cn, schemas.xmlsoap.org, data.openspeech.cn, alog.umeng.com, oc.umeng.com, etc., AC2020 of the distributed IPTV system 202 or Router 2020 of the non-distributed IPTV system 202 determines that this DNS request message requests the resolution of IPTV verification domains, and thus determines that this DNS request message is an IPTV message.

[0094] STB203 sends video stream addresses to AC2020 of the distributed IPTV system 202 or Router 2020 of the non-distributed IPTV system 202. For example, CCTV-1 General: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081813_0.smil; CCTV-2 Finance: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081816_0.smil; CCTV-4 Chinese International: rtsp: / / 180.1 41.207.228 / PLTV / *** / 10000100000000060000000000081812_0.smil, CCTV-7 National Defense and Military: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081852_0.smil, CCTV-10 Science and Education: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081839_0.smil, CCTV-12 Society and Law: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081817_0.smil, CCTV-13 News: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081820_0.smil, CCTV-14 Children's Channel: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081823_0.smil, Dragon TV: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081830_0.smil, Beijing TV: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081828_0.smil, Zhejiang TV: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081826_0.smil, Jiangsu TV: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081827_0.smil, Hubei TV: rtsp: / / 180.141.207.228 / PLTV / *** / 10000100000000060000000000081844_0.smil, etc., the AC2020 of the distributed IPTV system 202 or the routing 2020 of the non-distributed IPTV system 202 determines this video stream address as the IPTV video stream address;

[0095] STB203 sends a request message to AC2020 of the distributed IPTV system 202 or router 2020 of the non-distributed IPTV system 202. This request message is used to request a channel list, or to request the service entry address, such as homepage, live broadcast, on-demand, replay, etc., or to request login, upgrade, authentication, loading specific links, etc. AC2020 of the distributed IPTV system 202 or router 2020 of the non-distributed IPTV system 202 determines that the channel list request message is an IPTV request message.

[0096] S302. If it is determined that the first data stream is an IPTV data stream, then the LAN side port receiving the first data stream is determined as the first port, and the DHCP or PPPoE server is turned off when it is determined that only Internet data stream and IPTV data stream are received.

[0097] In some embodiments, after receiving the first data stream sent by the set-top box and determining that the first data stream is an IPTV data stream, the main router of the distributed IPTV system or any router of the non-distributed IPTV system can determine that the LAN-side port receiving the first data stream is the first port (STB port), and disable the DHCP or PPPoE server when it is determined that only Internet data stream and IPTV data stream are received. The first port is the LAN-side port connected to the set-top box through the first sub-router or directly connected to the set-top box, and the first sub-router is any sub-router of the distributed IPTV system.

[0098] For example, after receiving the first data stream sent by STB203 and determining that the first data stream is an IPTV data stream, AC2020 of distributed IPTV system 202 or router 2020 of non-distributed IPTV system 202 can determine that the LAN3 port of AC2020 or router 2020 receiving the first data stream is the first port. That is, LAN3 port is the LAN-side port of AC2020 connected to STB203 through AP2023, or LAN3 port is the LAN-side port of router 2020 directly connected to STB203.

[0099] It should be noted that, in this embodiment, the time point for disabling the DHCP or PPPoE server is after the first port is determined. Specifically, it can be after receiving the first data stream sent by the set-top box. If the first data stream is determined to be an IPTV data stream, then the LAN port receiving the first data stream is determined as the first port, and the DHCP or PPPoE server is disabled. Alternatively, it can be after receiving a DHCP message sent by the client, determining the service type of the client's MAC address based on the Option60 field in the DHCP message. If the field information is a field with SCITV or an encrypted field with @ITV, then the client's MAC address is of type IPTV, the LAN port receiving the DHCP message is determined as the first port, and the DHCP or PPPoE server is disabled. This embodiment does not impose specific limitations on this.

[0100] S303. If a DHCP or PPPoE response message is received from the IPTV server, the LAN port that receives the DHCP or PPPoE response message is determined to be the second port.

[0101] In some embodiments, after determining that the LAN-side port receiving the first data stream is the first port, and after disabling the DHCP or PPPoE server when determining that only Internet data stream and IPTV data stream are received, if a DHCP or PPPoE response message is received from the IPTV server, the LAN-side port receiving the DHCP or PPPoE response message is determined to be the second port (iTV port), wherein the second port is the WAN-side port connected to the IPTV port of the optical modem.

[0102] It should be noted that, in the embodiments of this application, after the main router of the distributed IPTV system or any router of the non-distributed IPTV system determines that the LAN side port receiving the DHCP or PPPoE response message is the second port, it can create an IPTV WAN, thereby binding the identified second port and restarting the DHCP or PPPoE server to transmit ordinary Internet access data.

[0103] S304. Based on the second port, send the first data stream to the optical modem.

[0104] In some embodiments, after determining that the LAN-side port receiving DHCP or PPPoE response messages is the second port, the main router of the distributed IPTV system or any router of the non-distributed IPTV system can first create a VLAN tag conversion table between the second port (the iTV port of the IPTV port connected to the optical modem upstream) and the first port (the STB port connected to the set-top box downstream). Based on the VLAN tag conversion table, VLAN tag conversion processing is performed on the first data stream. Specifically, the first VLAN tag corresponding to the first port and the second VLAN tag corresponding to the second port are determined. Based on the first VLAN tag and the second VLAN tag, the VLAN tag conversion table is updated. The updated VLAN tag conversion table includes the correspondence between the first VLAN tag and the second VLAN tag. Based on the updated VLAN tag conversion table, VLAN tag conversion processing is performed on the first data stream. For example, the first data stream is tag deleted, and the first data stream after tag deletion is sent to the second port. The tag deletion process is used to delete the first VLAN tag carried by the first data stream. Based on the updated VLAN tag conversion table, the first data stream after tag deletion is tag created on the second port. The first data stream after tag creation carries the second VLAN tag. The first data stream, after VLAN tag conversion, is sent to the optical modem via the second port. Then, based on the second port, the first data stream after VLAN tag conversion is sent back to the optical modem. This establishes a one-to-n VLAN tag conversion table, preventing IPTV data packets from being incorrectly transmitted to another set-top box port when all ports connected to the set-top boxes are in the same VLAN environment, thus making IPTV data packet transmission more flexible.

[0105] For example, such as Figure 4 The diagram shown is a schematic representation of a transparent transmission of IPTV data provided in an embodiment of this application. Figure 4In the distributed IPTV system 202, the STB203 sends uplink IPTV data packets to the AC2020. The AP2023, directly connected to the STB203, performs first tag creation processing on the uplink IPTV data packets. The uplink IPTV data packets after first tag creation carry a first VLAN tag, such as VLAN 3. After receiving the uplink IPTV data packets after first tag creation processing through its LAN3 port, the AC2020 performs tag deletion processing on the uplink IPTV data packets and then sends the tagged uplink IPTV data packets to the network. The data is sent to the iTV port. The tag deletion process is used to delete the first VLAN tag carried in the uplink IPTV data packet. Based on the VLAN tag conversion table, the second VLAN tag corresponding to the first VLAN tag is determined. The uplink IPTV data packet after the tag deletion process is processed on the iTV port to create a second tag. The uplink IPTV data packet after the second tag creation process carries a second VLAN tag, such as VLAN(X+1). The uplink IPTV data packet after the second tag creation process is sent to the optical modem 201 through the iTV port, thereby realizing the transparent transmission of the uplink IPTV data packet.

[0106] akin, Figure 4 The optical modem 201 sends downlink IPTV data packets to the AC2020 of the distributed IPTV system 202. The iTV port of the AC2020, which is directly connected to the IPTV port of the optical modem 201, performs a first tag creation process on the downlink IPTV data packets. The downlink IPTV data packets after the first tag creation process carry a second VLAN tag, such as VLAN (X+1). After receiving the downlink IPTV data packets after the first tag creation process through the iTV port, the AC2020 performs tag deletion processing on the downlink IPTV data packets and sends the tag-deleted downlink IPTV data packets to the distributed IPTV system 202. TV data packets are sent to the LAN3 port. The tag deletion process is used to delete the second VLAN tag carried in the downlink IPTV data packet. Based on the VLAN tag conversion table, the first VLAN tag corresponding to the second VLAN tag is determined. The downlink IPTV data packet after the tag deletion process is processed on the LAN3 port to create a second tag. The downlink IPTV data packet after the second tag creation process carries the first VLAN tag, such as VLAN3. The downlink IPTV data packet after the second tag creation process is sent to the STB203 through the LAN3 port, thereby realizing the transparent transmission of the downlink IPTV data packet.

[0107] It should be noted that, in the embodiments of this application, after updating the VLAN tag conversion table based on the first VLAN tag and the second VLAN tag, the main router of the distributed IPTV system or any router of the non-distributed IPTV system determines whether the connection between the first port and the set-top box has been broken. For example, the main router of the distributed IPTV system receives first information sent by the first sub-router, wherein the first information is used to indicate that the connection between the first sub-router and the set-top box has been broken, thereby determining whether the connection between the first port and the set-top box has been broken. Alternatively, any router of the non-distributed IPTV system directly determines whether the connection between the first port and the set-top box has been broken. If the connection between the first port and the set-top box has been broken, the correspondence between the first VLAN tag and the second VLAN tag is deleted in the updated VLAN tag conversion table, the second data stream sent by the set-top box is received, and it is determined whether the second data stream is an IPTV data stream. If the second data stream is determined to be an IPTV data stream, then the LAN port receiving the second data stream is designated as the third port. The third port is either a LAN port connected to the set-top box via a second sub-router or directly connected to the set-top box. The second sub-router is any sub-router in the distributed IPTV system other than the first sub-router. A mapping between the third VLAN tag and the second VLAN tag is created in the updated VLAN tag translation table, where the third VLAN tag is the VLAN tag corresponding to the third port.

[0108] For example, the user will Figure 2 In the distributed IPTV system 202, the connection between port A of AP2023 and STB203 is disconnected, and STB203 is connected to port B of AP2024 of the distributed IPTV system 202. AP2023 deletes the MAC address and port corresponding to STB203 stored in the forwarding database (FDB), and sends a first message to AC2020 of the distributed IPTV system indicating that the connection between port A of AP2023 and STB203 has been disconnected. After receiving the first message, AC2020 deletes the mapping relationship between VLAN3 and VLAN(X+1) in the VLAN tag conversion table. AC2020 receives the second data stream sent by STB203 and determines whether the second data stream is an IPTV data stream. If the second data stream is determined to be an IPTV data stream, then the LAN4 port receiving the second data stream is determined to be the third port. That is, the LAN4 port is the LAN side port of AC2020 connected to STB203 through AP2024. The correspondence between VLAN4 and VLAN(X+1) is deleted in the VLAN tag conversion table.

[0109] It should be noted that, in the embodiments of this application, the methods by which the direct route of the set-top box (such as the first sub-route or any route of the non-distributed IPTV system) determines that the connection between the port and the set-top box has been broken include the following: (1) determining whether the storage time of the MAC address of the set-top box stored in the FDB is greater than a first preset threshold. If it is greater, then the connection between the port and the set-top box is determined to be broken; (2) determining whether the time after sending an address resolution protocol (ARP) message to the set-top box without receiving a reply from the set-top box is greater than a second preset threshold. If it is greater, then the connection between the port and the set-top box is determined to be broken; (3) whether the route driver detects that the physical link is broken. If it detects that the physical link is broken, then the connection between the port and the set-top box is determined to be broken.

[0110] Based on the above technical solution, the main router of the distributed IPTV system or any router of the non-distributed IPTV system can receive the first data stream sent by the set-top box and determine whether the first data stream is an IPTV data stream. If the first data stream is determined to be an IPTV data stream, the LAN-side port receiving the first data stream is designated as the first port. When it is determined that only Internet data streams and IPTV data streams are received, the DHCP or PPPoE server is turned off. The first port is the LAN-side port connected to the set-top box through the first sub-router or directly connected to the set-top box. The first sub-router is any sub-router of the distributed IPTV system. If a DHCP or PPPoE response message is received from the IPTV server, the LAN-side port receiving the DHCP or PPPoE response message is designated as the second port. The second port is the WAN-side port connected to the IPTV port of the optical modem. Based on the second port, the first data stream is sent to the optical modem. By identifying IPTV data streams, the system identifies the LAN-side ports connected to the set-top box via the first sub-router or directly to the set-top box. It also identifies the WAN-side ports connected to the IPTV port of the optical modem by recognizing DHCP or PPPoE response messages. This avoids the need for manual user configuration to select the ports connecting the optical modem and set-top box, and eliminates the need to rely on the option60 field in DHCP uplink messages for automatic identification of these ports. Furthermore, it eliminates the need to pre-obtain the STB vendor list used for client OUI matching to automatically identify the ports connecting the optical modem and set-top box, thus improving user experience and covering all STB usage scenarios.

[0133] If the second data stream is determined to be an IPTV data stream, then the LAN-side port receiving the second data stream is determined to be the third port. The third port is a LAN-side port that is connected to the set-top box through the second sub-route or directly connected to the set-top box. The second sub-route is any sub-route of the distributed IPTV system other than the first sub-route.

[0134] Create a mapping relationship between the third VLAN tag and the second VLAN tag in the updated VLAN tag conversion table, wherein the third VLAN tag is the VLAN tag corresponding to the third port.

[0135] In one possible design, the fourth processing module is specifically used for:

[0137] If the time after sending an Address Resolution Protocol (ARP) message to the set-top box without receiving a reply from the set-top box exceeds a second preset threshold, then it is determined that the connection between the first port and the set-top box has been broken; or,

[0138] If the routing driver detects that the physical link is broken, it determines that the connection between the first port and the set-top box has been broken.
