Detailed Description

In order to meet the requirement that a user wants to use one network cable in a home to both surf the Internet and watch an interactive network Television (IPTV), the IPTV can be deployed flexibly in the following ways:

the method comprises the steps that firstly, a super administrator configuration page of a home gateway (Modem) is cracked, binding and port isolation of IPTV and Internet services are removed, and a Virtual Local Area Network (VLAN) binding rule is configured; or channel purchase without restriction home gateway (Modem), but configure the registered Optical Line Terminal (OLT) and then perform WAN/LAN/VLAN configuration (possibly also involving multicast VLAN configuration).

And selecting a high-end router supporting IPTV and VLAN configuration, and configuring VLAN and port binding in the IPTV subfunction.

And in the third mode, switches are respectively added at two ends of the single line to converge and separate IPTV services and Internet services.

And in the fourth mode, a router is added to the weak current box, the IPTV monopolizes a single line, only the sub-router is deployed in the center of the living room, and the weak current box router is connected through WiFi.

In a fifth mode, the network cable of the adapter bar 1000M is divided into two groups of 100M network cables. One for internet service and one for IPTV.

In the sixth mode, a pair of Power Line Communication (PLC) or WiFi bridges is added for IPTV streams to perform transceiving.

However, in the above schemes, the requirements for the personal network technology of the user are very high, for example, the advanced IPTV function of a home gateway (Modem) and a configuration router is broken, the switch configuration needs a command line, a gigabit network cable branch, and the like, and the common user cannot complete the configuration; and none of the above solutions supports distributed IPTV, i.e. the Set Top Box (STB) of the operator and the user is difficult to deploy in home.

Aiming at the existing problems, the data transmission scheme of the distributed network is provided, the STB and the common internet equipment are automatically identified on the main router of the home fabric network, the request of the STB and the common internet equipment is distributed to the bridge WAN connection and the route WAN connection, the downlink IPTV flow from an operator is correspondingly processed and forwarded to the correct destination equipment, and therefore the problem that the IPTV cannot be deployed at any place of a home is solved, and simplicity and flexibility of user networking are guaranteed.

The technical solution provided in the present application will be described in detail by several specific embodiments.

Fig. 1 is a schematic diagram of a distributed networking provided by the present application, as shown in fig. 1, in a home networking or other distributed networking such as networking that needs to transmit internet data and IPTV data simultaneously, taking home networking as an example, the distributed networking at least includes an optical modem connected to an optical fiber of a home, a main router, and a connection between the optical modem and the main router that needs to establish an internet access service and an IPTV service, where the two connections generally may be connected to different interfaces through two network cables respectively, and there is also a case where a bridge WAN and a route WAN connection are established in the same line, which does not limit the present solution. One or more internet access devices and one or more televisions and other devices for acquiring network television data can be connected below the main router. These ordinary internet devices and televisions may be directly connected to the main router, or may be connected to the main router through the sub-router, for example, in the home networking shown in fig. 1, the system further includes a sub-router 1 and a sub-router 2, and the two sub-routers may be connected through a wired or wireless connection; the sub-router 1 can be connected to other internet access devices STA through a network cable or wirelessly, and connected to the STB and the television through a network cable or wirelessly. The sub-router 2 can be connected to other internet devices STA through a network cable or wirelessly, and connected to The internet through a network cable or wirelessly to cross Over The television of an operator (Over The Top, OTT).

In a specific networking process, according to the actual networking situation of a user and the distribution mode of an operator IPTV service, a guide is installed in a main router to guide the user to correctly connect an uplink WAN port of the main router with a corresponding LAN port of a home gateway (Modem), and a bridge WAN and a route WAN connection between the main router and the gateway (such as a light cat) are established.

Fig. 2 is a schematic flow diagram of a first embodiment of a data transmission method for a distributed network provided in the present application, and as shown in fig. 2, this embodiment mainly shows an embodiment in which a network or an operator performs downlink data transmission in a similar network arrangement shown in fig. 1, where an execution subject is a router (that is, a master router in the networking), and the data transmission method for the distributed network specifically includes the following steps:

s101: and receiving first data sent by the bridging WAN and second data sent by the routing WAN, wherein the first data is flow data of the interactive network television, and the second data is network data.

In this step, in the process of transmitting the downlink data, the data is transmitted to the gateway through the optical fiber, and then transmitted from the gateway to the router, and in the process of transmitting the data to the router, different links are established between the gateway and the router, that is, a bridge WAN connection and a route WAN connection, the two connections may be established in the same physical line, or may be established in different physical lines, for example: the router and the gateway can be connected through two different network cables, and in the installation and setting process of the router, prompt is carried out through an installation guide to prompt a user to connect correct interfaces through different lines in the networking process.

As can be seen from the above description, the bridging WAN and the routing WAN are established in the same physical network; or, the bridging WAN and the routing WAN are respectively established in different physical network lines, which is not limited in this scheme.

After the connection between the gateway and the router is established, when a network needs to send downlink data to an upper network device or a set top box (or a television), after the data is transmitted to the gateway, the gateway issues the network data through the established route WAN connection, sends the network data to the router, issues the flow data of the interactive network television through the established bridge WAN connection, and sends the flow data and the network data to the router, namely the router receives the flow data and the network data, namely the first data and the second data, through different connections respectively.

S102: and aggregating the first data and the second data and then forwarding.

In this step, the router aggregates the two received data, that is, the network data to be sent to the ordinary internet access device and the traffic data of the interactive network television are aggregated together, and the aggregated data is sent to the device covered by the router as an integral downlink data.

In the specific implementation of the scheme, the method includes at least two forwarding modes after data aggregation:

in the first mode, when the lower end of the router is connected with a network device (for example, a terminal device such as a mobile phone, a computer, etc.) or a set top box (and/or a television) through a sub-router, the router aggregates the first data and the second data and then sends the aggregated first data and the aggregated second data to the sub-router connected below the router. And the sub-router sends the received data to the connected ordinary internet access equipment and the set-top box, and the received data automatically judges the required data to acquire.

In the second mode, the router is directly connected with common internet access devices (e.g., terminal devices such as mobile phones and computers) and set top boxes (and/or televisions) within a coverage area, that is, no other routing device is passed in the middle, at this time, after the router receives downlink second data (network data) and first data (traffic data), the first data and the second data are aggregated and then sent to the set top box device and/or the terminal device connected below the router, and since the receiving device obtains required data for processing such as display or playing. In one specific implementation of this approach, IPTV streams are only sent to set-top boxes, internet streams are only sent to mobile/PC devices.

In the data transmission method of the distributed network provided by this embodiment, a router WAN and a bridge WAN connection are established between a router and a gateway to respectively receive different data, and the router can aggregate the data and then forward the aggregated data, mainly issue the aggregated data to a sub-router connected below the router, or an internet access device or a set top box device.

Fig. 3 is a schematic flowchart of a second embodiment of a data transmission method for a distributed network provided in the present application, and as shown in fig. 3, this embodiment mainly shows that, on the basis of the foregoing embodiment, a router needs to determine whether to connect a set top box device in a coverage manner, so as to determine whether to forward after receiving traffic data of an interactive network television, and needs to determine a type of a device connected within a coverage range of the router in advance. The embodiment provides a specific implementation manner, which includes the following steps:

s201: and receiving a networking request message sent by the networking equipment, wherein the networking request message comprises the identification of the networking equipment.

In this step, devices within the coverage of the router, including mobile phones, computers, intelligent home appliances, set-top boxes, televisions, and other devices, may become networking devices, and when connecting to a network through the router, it is necessary to send a networking request message to the router, and in order to enable the router to determine a device and perform authorization, the networking request message at least needs to include an identifier of the networking device, so as to be able to determine which device the networking device is, where the identifier may be a name of the device itself or a name of a device manually set by a user, and this application is not limited thereto.

S202: and identifying whether the networking equipment is the set top box equipment or not according to the networking request message.

In this step, the router may identify the networking device according to the networking device message, and in a specific implementation, the router may identify the networking device by using an identifier of the device, for example, identifiers of various types of set top box devices are stored in a database of the router or a server of the router, and the router may compare the identifier of the set top box device in the database or the server with the identifier of the networking device by using the identifier of the router, determine that the networking device is the set top box device if the identifier of the networking device is matched with the identifier of the database or the server, and determine that the networking device is not the set top box device otherwise.

Optionally, in another implementation manner, the characteristics of the networking request message may also be used to determine whether the networking device is a set top box device, and after receiving the networking request message, the router determines whether the characteristics of the networking request message match the characteristics of the set top box device stored in the set top box characteristic database; and if the set top box device is matched with the networking device, determining that the networking device is the set top box device. The set-top box feature database may include at least one of a MAC address in a historical set-top box sending request, an Organization Unique Identifier (OUI) field in the MAC address, manufacturer information of the set-top box, and other feature information of the set-top box device, which is not limited in this scheme.

Optionally, in another implementation manner, the networking request message further includes an MAC address of the networking device, and when a connection with the router needs to be established, the router can acquire the MAC address of the networking device and display the MAC address by itself or display the identifier and the MAC address of the networking device on a computer or other devices when the router is set up, according to the networking request message. And determining whether the networking equipment is set top box equipment or not by the user according to the MAC address and/or the equipment address of the applied service, namely configuring the networking equipment into the set top box equipment according to the operation of the user, or selecting that the equipment is not the set top box equipment.

S203: and if the networking equipment is set top box equipment, storing the identification of the networking equipment and marking the networking equipment as the set top box equipment.

In this embodiment, the router may identify all devices within the coverage area in the above manner, determine whether there is a set-top box device, and if it is determined that a certain networking device is a set-top box device, identify the set-top box device locally, so that data can be reasonably forwarded in a subsequent data transmission process.

Specifically, if there is no device such as a set top box (and/or a television) in the router networking device, even if the router receives the traffic data of the interactive network television in the data retransmission process, the traffic data does not need to be issued.

The data transmission method of the distributed network provided by this embodiment specifically provides a way of determining whether the networking device is a set-top box device in a centralized manner, and identifies the devices connected within the coverage area of the router in the networking process or the setting process of the router, so that correct forwarding can be performed in the data transmission process.

Fig. 4 is a schematic flowchart of a third embodiment of a data transmission method for a distributed network provided in the present application, and as shown in fig. 4, in the networking mode shown in fig. 1, when there is uplink data transmission in an online device or a set-top box television, and the like, data forwarding needs to be performed through a router, where this embodiment provides an uplink data transmission method in a distributed network, and specifically includes the following steps:

s301: and receiving the uplink data sent by the sub-router.

In this step, taking home distributed networking as an example, when both a terminal device for ordinary internet access and a set-top box of a television set perform uplink data transmission, the devices at the sending end directly send data to a main router in the networking, or send the data to the main router through a connected sub-router, and after receiving uplink data, a router connected to a gateway (i.e., the main router) needs to upload the data through the gateway.

S301: and shunting the uplink data to obtain first data and second data, wherein the first data is flow data of the interactive network television, and the second data is network data.

S301: first data sent to a gateway through a bridging WAN, and second data sent to the gateway through a routing WAN.

In the scheme, the router needs to shunt after receiving the uplink data, if the traffic data and the network data are received from two different devices directly, the traffic data and the network data can be distinguished directly, if the uplink data are received from the sub-routers, the traffic data of the interactive network television can be shunted according to the characteristics of the data, such as the type and the like, after the shunting, the router sends the traffic data of the interactive network television to the gateway through the bridge connection WAN, and the network data is sent to the gateway through the connection of the router connection WAN, so that the gateway can forward different data to different servers respectively.

In the implementation of this embodiment, the router may also identify a networking device within the coverage area or a networking device that sends the upstream data, determine and record whether the networking device is a set-top box device, and perform label storage. The specific identification scheme is similar to that of the embodiment shown in fig. 3 and can be implemented with direct reference to the embodiment shown in fig. 3.

In the data transmission method of the distributed network provided by this embodiment, in the uplink data transmission process, devices connected under the router, for example, sub-routers transmit network data that is on line and traffic data of a television together, and the router receives the uplink data, then shunts the data, and transmits the data through different connections with the gateway, so that the gateway can identify what type of data the data is.

In combination with any of the above embodiments, in the data transmission of the distributed network provided by the present application, the IPTV request of the STB and the internet access request of the common device are automatically identified on the main router, so as to distinguish the IPTV device from the common internet access device. The requests of the STB and the common internet access device are distributed to different logical WAN connections (namely, connections capable of establishing routing and bridging on a physical WAN) or physical WAN connections (the physical WAN connection represents the condition of a plurality of physical uplink ports, and the logical WAN connection represents the condition of a plurality of virtual WAN interfaces under one physical uplink port), and corresponding processing is carried out on downlink IPTV traffic from an operator and the downlink IPTV traffic is forwarded to a correct destination device. In a return link (comprising WiFi, PLC, ethernet and the like), IPTV and common internet traffic are transmitted in a mixed mode, the IPTV and the internet traffic defined by a common operator are not limited to be carried by different physical LAN ports, service mixed flow can reach any place covered by home distributed routing, and meanwhile, a router can guarantee transmission quality of the IPTV traffic, so that the problem that the IPTV cannot be deployed at any place of a home is solved, and simplicity and flexibility of user networking are guaranteed.

In a specific implementation scheme, for example, in a home networking mode shown in fig. 1, an optical fiber in a weak electrical box is connected to a home through a home gateway (i.e., a Modem of a Modem), a main router may also be disposed in the weak electrical box, and the main router and the quality inspection of the Modem of the optical Modem may be connected through two network cables to respectively establish transmission channels for an internet access service and an IPTV service. In the living room, the television comprises a common internet access device STA and a television connected through a set-top box, the television and the STA can be connected with the quality inspection of the main router through a sub-router 1, similarly, the STA of the common internet access device and the television connected through OTT exist in the bedroom, the television and the STA can be connected with the sub-router 1 through a sub-router 2 or directly connected with the main router, and the specific connection mode can be a wireless or wired mode, which is not limited.

In the networking installation process shown in fig. 1, according to the actual networking situation of the user and the distribution mode of the IPTV service of the operator, the router installation guide guides the user to correctly connect the uplink WAN port of the main route with the corresponding LAN port of the home gateway (Modem).

In the networking process, the main router intelligently identifies the STB through a local database or a cloud interface according to the characteristics in the STB networking request message, and the identified networking equipment marks the networking equipment as STB equipment.

Then, in a specific forwarding process, the main router transmits downlink IPTV and common internet traffic in a mixed manner, and is not limited to that the IPTV and the internet traffic defined by a general operator are carried by different Local Area Network (LAN) ports, and the service mixed stream can reach any place covered by the home distributed routing, and meanwhile, the router guarantees the transmission quality of the IPTV traffic.

The networking and data transmission process in the distributed networking are explained through specific embodiments.

1. Router installation guide

a. The IPTV of the home gateway (Modem) is carried over a separate LAN port, commonly referred to as iTV port. The guide guides the user to connect the IPTV port and the common Internet port to the WAN port of the main router by two network cables, and the corresponding relation between the two WAN ports of the router and the service is configured in the installation guide.

b. The IPTV and the Internet service of a home gateway (Modem) are carried through the same LAN port. The wizard guides the user to connect the port to the router's WAN port using a network cable.

2. STA device intelligent identification

The user can access the STB to any access Point (WiFi or Ethernet) of the home distributed networking, after the STB is powered on, the STB automatically initiates a Dynamic Host Configuration Protocol (DHCP) request or a Point-to-Point Protocol Over Ethernet (PPPoE) dialing request based on the Ethernet, and the main router identifies the source MAC address and the characteristics of a request message of the STB according to corresponding rules.

In a specific implementation, the home gateway IPTV WAN mode includes a routing mode and a bridging mode, in the routing mode, the network mode of the STB acquires an address allocated by the home gateway (Modem) for DHCP, and the router can identify whether the request is issued by the STB device through option125 or option60 of DHCP, a database of MAC addresses, and then determine whether the networking device is the STB device. In the bridge mode, the network mode of the STB comprises a mode that PPPoE dialing acquires an address distributed by a BRAS, or DHCP acquires an address distributed by a Broadband Remote Access Server (BRAS), in the mode that the PPPoE dialing acquires the address distributed by the BRAS, the router works in a routing mode, normal internet equipment does not send a PPPoE dialing request, so that the STB equipment must send the PPPoE dialing request, and in addition, joint judgment can be carried out by combining an MAC address database; in the mode where the DHCP obtains the BRAS assigned address, the router identifies whether the request was made by the STB device by way of the DHCP option125, or option60, the home base of MAC addresses, to determine whether the networking device is an STB device.

Specifically, the STB feature database can be established to support the joint matching and partial matching of option125, option60 and MAC addresses, so that the accurate identification of the STB can be completed to the maximum extent, and meanwhile, the STB feature database can be matched more accurately through data provided by an operator; and supports interfacing with the operator's server to accomplish identification of the STB.

In the specific implementation of the above scheme, after receiving the DHCP request, the identification is performed by analyzing a certain protocol field (for example, option 60) therein, and in addition, a database may be formed according to the OUI field in the MAC address and the information of the manufacturer, and the database is searched according to the source MAC of the DHCP request to determine whether the database is a set-top box device, or other characteristics of a set-top box type device may be gradually added to the database to identify the set-top box, which is not limited in this scheme.

If the problem that the STB cannot be correctly identified exists, the user can manually set the STB aiming at the equipment MAC, and the result can be automatically stored in the router configuration and the cloud. The subsequent user can complete the automatic identification process by restoring the router to factory configuration or replacing a new router without manual setting.

3. Aggregation and shunt forwarding of IPTV stream and Internet data by main router

Fig. 5a-5b are schematic diagrams of WAN modes in distributed networking according to an embodiment of the present application. As shown in fig. 5a, when the dual WANs go upstream, the main route establishes a bridging WAN based on the internet WAN port, and establishes a router WAN connection based on the IPTV WAN port; as shown in fig. 5b, when a single WAN is upstream, the main route simultaneously establishes a bridging WAN + a routing WAN port based on the upstream WAN port.

The internet access device in the figure transmits an IPTV stream transmitted by the network device and the STB device. In the schematic diagrams of the two modes described above, only the bridging WAN can be used for IPTV traffic.

The main router needs to identify all the STB devices which are hung down, and if the STB devices cannot be identified, the main router does not allow any message to be forwarded to the bridge WAN port; if an IPTV feature is identified, it is considered to be an STB; situations where no recognition or misrecognition is possible require the user to specify the STB device via an Application (APP) or World Wide Web (Web).

Fig. 6a to 6b are schematic diagrams illustrating a data requesting process in a distributed networking according to an embodiment of the present application. As shown in fig. 6a, the main route performs uplink forwarding to the IPTV bridge connection according to the STB MAC in the DHCP request (uplink data) sent by the STB device, and during the backhaul routing of the message, before forwarding the request to the gateway or the office device, it may be determined that the device is the STB device for marking according to the sent data request. Then, after the home router feeds back a DHCP response (downlink data) to the gateway or the office device, the DHCP response is forwarded to the STB device through the slave router (i.e., the sub-router). If the STB has the VLAN, transparent transmission is carried out during route forwarding, namely the route is directly carried to a home gateway (Modem) without modification. The specific IPTV request and IPTV stream are transmitted in the same manner.

As shown in fig. 6b, when a Personal Computer (PC) sends a DHCP request, the router recognizes that the device is not a STB device, and determines that the request is network data, at this time, the request may be sent through a WAN connection with a gateway or a central office device, and the same gateway or central office device also feeds back a DHCP response corresponding to the PC through the WAN connection, and in a subsequent process, the network request and the network stream (network data) are also transmitted in this manner.

In summary, in the data transmission method of the distributed network provided by the application, the STB devices at any position in the distributed packet network are intelligently identified through the combination of the local database and the operator cloud interface and the end cloud. Meanwhile, network data and IPTV traffic (namely traffic data) of the internet are aggregated and distributed through double WAN connection, and the method is suitable for IPTV networking modes of different operators.

And based on the MAC address of the STB, bridge binding based on equipment is realized, so that common internet traffic and IPTV traffic are distributed, a downlink multicast stream is converted into a unicast stream on a main router, and the reliability of transmission can be ensured.
