Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Firstly, the self-defined nouns in the embodiment of the invention are explained and explained:
the first interface is used for processing the STA data stream of Untag and an EasyMesh protocol message in a first networking mode, and processing the EasyMesh message and the STA data stream with VLAN in a second networking mode, wherein the first interface is represented by eth0.mesh in the embodiment of the invention;
the second interface is used for processing the STA data stream with the VLAN, and is represented by eth0.sta in the embodiment of the invention;
the third interface is used for processing the set-top box Internet network data stream, and is represented by eth0 in the embodiment of the invention, namely the A plane in the first networking mode exists only in the first networking;
a fourth interface, configured to process an IPTV service, which is a B plane in the first networking mode, and is denoted as eth0.iptv in the first networking mode, and is denoted as eth0 in the second networking mode;
a wireless interface, represented in the present embodiment by ap 0;
the bridge interface, in the present embodiment, is denoted br 0.
The fourth interface is a traditional interface; the first interface and the second interface are special interfaces for processing the EasyMesh protocol message and the STA data stream.
The current networking mode of the Chinese telecommunication set top box comprises two modes:
the first networking mode is as follows: an A/B plane, wherein the A plane is an Internet service, data is carried by an Untag message, an eth0 interface (namely an uplink network port of the set-top box) is represented on the set-top box to acquire a local area network IP (for convenience of description, the default uplink equipment local area network segment is 192.168.1.x), and the local area network IP is distributed by uplink equipment and accesses a network through a route of the uplink equipment; the B plane is IPTV service, carried by appointed VLAN data, presented as eth0.iptv interface on the set-top box to obtain private network IP distributed by IPTV network, and accessed to IPTV network through Bridge of the uplink device. The uplink device of the set-top box is bound by a Virtual Local Area Network (VLAN), so that one port (a port where the set-top box is connected to the uplink device) provides two services.
The second networking mode only supports IPTV service, is carried by Untag data, is represented as an eth0 interface on the set-top box to acquire a private network IP distributed by the IPTV network, and accesses the IPTV network through the Bridge of the uplink equipment. The existing set-top box has no data LAN < - - > WAN forwarding concept.
Mesh is a solution given by several major WiFi chip manufacturers at present, for example, in an EasyMesh network, a protocol stack binds to a bridge br0 (for convenience of description, a default set-top box bridge is br0), a WAN side bridge interface in the bridge is used as an interface interacting with an uplink AP Controller message, carries an EasyMesh protocol message, and carries a sub-routing STA data stream.
As shown in fig. 2, for the first networking mode of the set-top box, in order to obtain an Internet network and satisfy the easy mesh networking, a bridge br0 needs to be created, and eth0 and AP0 (interfaces where set-top box devices provide AP functions downwards) are added to the bridge br0, under this networking, the set-top box data stream, the STA data stream, and the easy mesh protocol packet are all unotag, and according to the Linux kernel protocol forwarding principle, the set-top box data stream that should be terminated at eth0 is finally sent to the bridge br0, which causes the set-top box service to be abnormal. For example, some set top box services are strongly bound to an eth0 interface, so that the set top box services cannot normally receive and send data from the eth0, and the set top box services are abnormal because the data all go to br 0.
Based on the above problem, the present invention proposes a networking method, as shown in fig. 3. The set-top box adds a special interface for processing an easy mesh protocol message and an STA data stream on the basis of reserving a traditional interface for processing own service, the special interface is bound with a bridge interface and a wireless interface, the set-top box distinguishes the easy mesh protocol message according to the Ethernet protocol type, distinguishes the Internet network data stream and the STA data stream of the set-top box according to the message destination MAC, and processes the IPTV service data stream by the traditional interface, and the special interface can be automatically configured or manually configured.
Internet network data, easy mesh protocol messages and STA data streams are Untag, and are processed by a set top box eth0 interface in a default Linux protocol stack. Whereas eth0 needs to be added to bridge br0 according to the EasyMesh networking requirements. In this case, the Internet network data of the downstream set-top box is forwarded to br0, which causes the own service exception of the set-top box. The socket creating mode of the set top box own service is to bind an interface eth0, all services monitor messages received by eth0, and if the condition that the EasyMesh networking is satisfied, the eth0 is bound in br0, the final receiving interface of the message is br0, and the set top box own service is abnormal. After adding the virtual interface eth0.mesh binding br0, it can be ensured that if the set top box self service and the STA service, and the EasyMesh protocol message (e.g. IEEE1905 protocol message) can be distinguished and sent to different interfaces, the service does not conflict. And subsequently, the method of judging a protocol, a VLAN, a destination MAC and the like is used for distinguishing the three types of messages.
As shown in fig. 4, for the second networking mode of the set top box, the port of the uplink device connected to the set top box temporarily does not provide Internet service (the port is bound with Bridge service), and a networking scheme between the uplink device and the set top box needs to be provided.
In order to achieve the above purpose, the invention provides a networking system for implementing easy mesh based on a set-top box WiFi, comprising a set-top box uplink device AP Controller and a set-top box, wherein:
the set-top box uplink device (AP Controller): (1) as shown in fig. 3, under the first set-top box, the AP Controller has provided Internet service to the set-top box without change; (2) as shown in fig. 4, in the second networking of the set-top box, the AP Controller only provides IPTV Bridge service to the set-top box, and needs to configure VLAN binding service at a port connected to the set-top box, and agree to bind VLAN ID { Internet } (optional) to the Internet route of the device, and in this networking, the data packet whose set-top box VLAN ID is Internet will be forwarded through the route of the AP Controller. According to the limitation of China telecommunication on the data forwarding of the Other Bridge binding port, the EasyMesh protocol message is also forwarded by the VLAN data.
The set top box (Agent) to which it belongs: when the set-top box is started, judging the current networking mode, (1) when the set-top box is a first networking mode, establishing an eth0.mesh interface, and processing an STA data stream of Untag and an EasyMesh protocol message; (2) and when the network is the second networking, establishing an eth0.mesh interface, and configuring the interface to process STA data stream and EasyMesh protocol message of which the VLAN is the Internet.
Further, the invention provides a networking method for realizing easy mesh based on a set top box WiFi, wherein the networking mode is manual, and the method comprises the following steps: in a first networking mode, the traditional interface is a third interface and a fourth interface, and the special interface is a first interface; or, in the second networking mode, the conventional interface is a fourth interface, and the dedicated interface is the first interface; the first interface is used for processing an Untag STA data stream and an EasyMesh protocol message in a first networking mode, and processing the EasyMesh message and the STA data stream with a VLAN in a second networking mode; the third interface is used for processing Internet network data flow of the set top box, and the fourth interface is used for processing IPTV service.

The processing mode of the downlink data is as follows: reading the message protocol type, judging whether an EasyMesh protocol message exists or not, if yes, sending the message to a first interface for receiving, and if not, entering the next step; analyzing the message VLAN, judging whether the VLAN ID is equal to the VLAN configured for the STA data stream, if equal, sending the message to a first interface for receiving, and if not, entering the next step; judging whether the Untag message exists or not, if not, processing the Untag message by a Linux VLAN protocol stack according to default rules, and if so, entering the next step; and analyzing the message destination MAC, judging whether the destination MAC is equal to the address of the third interface or the fourth interface, if so, indicating that the message is a data message of the self-service of the set top box, and if not, judging whether the message is broadcast and processed.

step S101: starting the set top box;
step S102: initializing a network interface eth0/eth0.iptv for bearing the self service of the set top box;
step S103: reading the networking mode of the current set top box;
step S104: if the set top box is in the second networking mode, initializing an eth0.mesh interface, reading VLAN configuration (assuming that VLAN ID is Internet) connected with Bridge of the set top box, and setting eth0.mesh to process the VLAN;
step S105: if the first networking mode is adopted, initializing an eth0.mesh interface, and setting eth0.mesh to process the Untag message;
step S106: the initialization of the WiFi module of the set top box is completed, and an ap0 interface is created; creating a bridge br0, adding eth0.mesh and ap0 into br0 to form a set top box bridge, forwarding STA data stream, forwarding an easy mesh networking message (an easy mesh protocol message, namely IEEE1905.1 or IEEE1905.1a), completing networking of the set top box, and waiting for message forwarding;
step S107: in the uplink data, the set top box has a service (eth0/eth0.iptv), and the STA data stream and the EasyMesh protocol message are controlled and processed (eth0.mesh) by a native Linux protocol stack. The processing logic is as follows: the set top box has a service message, a socket binding port is established by the set top box, and finally the set top box is determined by the set top box routing and is forwarded by eth0 or eth 0.iptv; the STA data stream is received by an ap0 interface, and the data is transmitted to eth0.mesh for forwarding according to the forwarding principle of the Linux bridge protocol stack; and the EasyMesh protocol message is controlled by a set top box creating socket. The downlink data forwarding logic is as follows;
step S108: reading the message protocol type, judging whether an EasyMesh protocol message (the Ethernet protocol type is 0X893A) exists, if yes, turning to the step S109, and if not, turning to the step S110;
step S109: sending the message to eth0.mesh for receiving;
step S110: analyzing the message VLAN, judging whether the VLAN ID is equal to the Internet (configured in step S104), if so, determining the message VLAN ID is equal to the Internet, if so, determining the message VLAN ID is an STA data stream (in the case, the STA data stream is in a second networking mode and is provided with the VLAN), turning to step S111, and if not, turning to step S112;
step S111: sending the message to eth0.mesh for receiving;
step S112: judging whether the Untag message exists, if so, turning to the step S114, otherwise, turning to the step S113;
step S113: the Linux VLAN protocol stack is processed by default rules and is served by a fourth interface eth0.iptv; wherein, S112 and S113 are used for eth0.iptv of the first networking;
step S114: analyzing the message destination MAC, judging whether the destination MAC is equal to the eth0 interface address, if so, indicating that the message is a data message of the self service of the set top box, and turning to the step S115, and if not, turning to the step S116;
step S115: the message is received by eth 0;
step S116: judging whether to broadcast the message, if so, turning to the step S117, otherwise, turning to the step S118;
step S117: after the message is copied, the message is respectively sent to eth0 and eth0.mesh for receiving;
step S118: judging whether to multicast the message, if so, turning to the step S119, and if not, turning to the step S120;
step S119: multicast group forwarding is carried out according to an eth0 and an eth0.mesh interface; wherein, S115, S117 and S119 are all used for eth0 (the first networking can be set top box plane A Internet, the second networking can also be traditional plane B IPTV, namely a third interface and used in the first networking, and can also be a fourth interface and used in the second networking);
step S120: if the two are not the same, the STA unicast message is considered to be received by eth0.mesh, and data is forwarded to the STA through the bridge, in which case, the first networking is performed, and the STA data stream is unoag.
Based on the Chinese telecommunication specification, the Other Bridge cannot forward br0 data, so that the EasyMesh protocol message VLAN values are different and established in two networking modes. With further application of easy mesh and set-top box WiFi networking, the set-top box and set-top box uplink equipment can further restrain forwarding of an easy mesh protocol message and achieve consistency, if the easy mesh protocol message is a Untag message, in this case, a VLAN of set-top box Internet data can be carried by the easy mesh protocol message, and the set-top box dynamically configures a data processing interface of an STA by analyzing the VLAN.
Under the scheme, the set top box does not need to pay attention to the current networking mode, and only needs to pay attention to the VLAN value carrying the data of the Internet. According to the EasyMesh protocol, in the configuration synchronization phase, the Controller replies Message M2 Message with optional field < other >, which can specify VLAN value. Later, if the standard is formed, other fields may be used, such as some reserved fields of the discovery phase.
The general message format of the EasyMesh protocol message is shown in fig. 6. The data content of M2 is shown in fig. 7, where the data content of the protocols is different in different interaction stages 1905.1.

step S205: judging whether the VLAN value is Untag, if not, the STA data stream is also forwarded by eth0.mesh, turning to step S206, and entering a data packet processing state; if yes, go to step S207;
step S206: according to the VLAN value, a network interface eth0.sta for processing the STA data stream is created, the eth0.sta is added into the bridge br0, and the step S207 is carried out;
step S207: in the uplink data, the set-top box has a service (eth0+ eth0.iptv (first networking) or eth0 (second networking)), and the STA data stream and the EasyMesh protocol message are controlled and processed by a native Linux protocol stack (eth 0.mesh). The processing logic is as follows: the set top box has a service message, a socket binding port is established by the set top box, and finally the set top box is determined by the set top box routing and is forwarded by eth0 or eth 0.iptv; the STA data stream is received by an ap0 interface, and the data is sent to eth0.mesh or eth0.sta for forwarding according to the Linux bridge protocol stack forwarding principle; and the EasyMesh protocol message is controlled by a set top box creating socket. The downlink data forwarding logic is as follows;
step S208: reading the message protocol type, judging whether an EasyMesh protocol message (the Ethernet protocol type is 0X893A) exists, if yes, turning to the step S209, and if not, turning to the step S210;
step S209: sending the message to eth0.mesh for receiving;
step S210: analyzing the message VLAN, judging whether the VLAN ID is equal to the Internet (configured in step S206), if so, turning to step S211 for the STA data stream with the VLAN (namely, the second networking mode), and if not, turning to step S212;
step S211: sending the message to eth0.sta for receiving;
step S212: judging whether the Untag message exists, if so, turning to the step S214, otherwise, turning to the step S213;
step S213: the Linux VLAN protocol stack is processed by default rules and is served by a fourth interface eth0.iptv; wherein, S212, S213 are used for eth0.iptv of the first networking;
step S214: analyzing the message destination MAC, judging whether the destination MAC is equal to the eth0 interface address, if so, indicating that the message is a data message of the self service of the set top box, and turning to the step S215, and if not, turning to the step S216;
step S215: the message is received by eth 0;
step S216: judging whether to broadcast the message, if so, turning to the step S217, otherwise, turning to the step S218;
step S217: after the message is copied, the message is respectively sent to eth0 and eth0.mesh for receiving;
step S218: judging whether to multicast the message, if so, turning to the step S219, otherwise, turning to the step S220;
step S219: multicast group forwarding is carried out according to an eth0 and an eth0.mesh interface; wherein, S215, S217 and S219 are all used for eth0 (the first networking can be set-top box plane A Internet, the second networking can also be traditional plane B IPTV, namely a third interface and used in the first networking, and can also be a fourth interface and used in the second networking);
step S220: if the two are not the same, the STA unicast message (multicast and broadcast are processed on other interfaces, here, the STA unicast message) is considered to be received by eth0.mesh, and the data is forwarded to the STA through the network bridge. In the auto-configuration case, only eth0.mesh in the first subnet mode is possible here; since the STA is VLAN-attached in the auto-configuration second networking case, it has been handled in eth0.sta described above.
It should be noted that, in the scenario of fig. 10, an eth0.sta processes an STA packet with a VLAN, and if the STA packet does not have the VLAN, the eth0.mesh processes the STA packet.
For the above embodiment, whether the manual or automatic networking mode is adopted, if the two modes are not equal, whether the broadcast message is broadcasted or not is determined, and the processing includes:
judging whether the message is broadcast or not, if so, copying the message and then respectively sending the message to a first interface and a third interface or a fourth interface for receiving, and if not, entering the next step;
judging whether to multicast the message, if so, forwarding the message according to the first interface and the third interface or the fourth interface multicast group, and if not, entering the next step;
if not, the STA unicasts the packet, the packet is received by the first interface, and the data is forwarded to the STA through the network bridge.
