Background

Accessing a digital broadband television IPTV (Internet Protocol television) network through a Point-to-Point communication Protocol PPPoE (Point to Point Protocol Ethernet) account based on a local area network is a network access verification mode. The interface link corresponding to PPPoE is a link created on an ethernet ETH (ethernet) interface, and is also a data transmission on an ETH physical port, but a point-to-point protocol ppp (point protocol) protocol is applied for dialing. In this case, there are generally two paths for multicast data: one is to transmit the data packets to the ue through the corresponding link of the PPP protocol, and each data packet has a PPP frame header and an ethernet frame header. The other is directly over the ethernet link. Under normal conditions, which network access authentication mode is used, which multicast link data is sent. However, in the recent past, such a scenario has emerged: when the PPPoE access mode is used, multicast stream data from an operator needs to be transmitted through an Ethernet link; and some hotels provide local multicast live data independent of IPTV, and need to play multicast data streams established by local ethernet routers in case of network access by PPPoE links.

A first embodiment of the present invention provides a network link processing method, and referring to fig. 2, fig. 2 is a schematic flow diagram of the first embodiment of the network link processing method of the present invention, where the network link processing method includes:

step S10, when receiving the multicast adding instruction, setting the socket IP as the IP of the PPPoE link, and determining whether multicast data is received in a first preset time period;

a digital broadband television iptv (internet Protocol television) is a new service that provides accurate digital multimedia services to users by using internet cable network resources and network technologies such as unicast and multicast, and using a h264 video compression method. It is being widely popularized with the continuous improvement of broadband operator services. The multicast technique is a technique of making full use of the replication capability of a network node. For users watching the same channel live broadcast, the users can join the same multicast group, and the network node copies the data to the corresponding user home, so that only one part of media data on the backbone network can be provided, and the effect of reducing the bearing pressure of the backbone network is achieved.

The PPP protocol is connected from the bearing point to the point on the Ethernet, a large number of hosts form a network by utilizing the Ethernet, the Internet is connected through a remote access device, the control and charging functions are realized for each accessed host, and the PPPoE is widely applied to a series of applications including cell group network construction and the like due to the extremely high cost performance. Ethernet ETH is a baseband lan specification and is also the most common communication protocol standard used by today's existing lans. The point-to-point protocol ppp (point-to-point protocol) provides an encapsulation protocol for IP traffic transmission between two peer nodes. In the TCP-IP protocol suite, it is a data link layer protocol used to synchronously modulate connections, replacing the original non-standard second layer protocol, SLIP. Point-to-Point communication Protocol PPPoE (Point to Point Protocol over ethernet) based on lan is a newly developed standard to meet the communication between more and more broadband internet devices and faster networks, and is based on two widely accepted standards: local area network Ethernet and PPP point-to-point dial protocols. Compared with other protocols, PPPoE has the advantages that for an end user, the user does not need to know a deeper local area network technology, and only needs to use the technology as a common dial-up networking technology, for a service provider, huge expenses are not needed to be spent on large-area transformation on the basis of the existing local area network, and an IP address binding user is set to support a private line mode. The essence of PPPoE is a relay protocol between Ethernet and dial-up network, which inherits the advantages of Ethernet such as high speed and PPP dial-up simplicity, user authentication, IP allocation and the like. In practical application, PPPoE uses the working mechanism of Ethernet to interconnect the 10 BASE-T interface of ADSL Modem with internal Ethernet, after the ADSL Modem adopts the bridge packaging mode of RFC1483 to carry out LLC/SNAP packaging on the PPP packet sent by the terminal, the connection is established between the ADSL Modem and the broadband access server at the network side through the PVC connecting the two ends, thus realizing the dynamic access of PPP. The port number socket is also called a socket, is used for describing an IP address and a port, is a handle of a communication chain, and can be used for realizing communication between different virtual machines or different computers.

The network access authentication method of the IPTV network generally includes access to a DHCP + or PPPoE account. The PPPoE interface is a link created by dialing by applying PPP protocol over ETH interface, and is essentially data transmission over ETH physical port. Therefore, in this case, the multicast data may be transmitted through two paths, the first path is to transmit the multicast data to the user end through the PPPoE link corresponding to the PPP protocol, and each packet has a PPP frame header and an ethernet frame header; the other is to send directly to the user end through the ethernet link.

When the user opens the IPTV, the user requests any program through the IPTV, namely, the user sends a multicast adding instruction. And when the IPTV terminal receives the multicast adding instruction, establishing a multicast socket, setting a socket IP as the IP of the PPPoE link, adding a multicast group corresponding to the multicast instruction based on the IP of the PPPoE link, monitoring the socket, and determining whether multicast data is received in a first preset time period. The first preset time period may be set by a technician, for example, set to 500ms, and then after the IPTV terminal joins the designated multicast group, the socket is monitored for 500ms to determine whether multicast data is received in this time period.

Step S20, when the multicast data is not received in the first preset time period, resetting the socket IP as the IP of the ETH link, and determining whether the multicast data is received in the second preset time period;

and if the multicast data sent by the appointed multicast group is not received in the first preset time period, trying to switch the link when a judgment result that the link switching action is not executed before is obtained. Specifically, first leave the previous multicast group, then modify the socket IP to the IP of the ETH link, join the multicast group based on the IP of the ETH link and listen to the socket data.

Step S30, when the multicast data is not received within the second preset time period, setting the socket IP as the IP of the PPPoE link again.

If the multicast data sent by the appointed multicast group is not received in the second preset time period, when the judgment result of executing the link switching action is obtained, the switching back to the PPPoE link is tried, at the moment, the previous multicast group still leaves, then the socket IP is modified again to be the IP of the PPPoE link, and the switching back to the PPPoE link is carried out again.

Further, in an embodiment, before step S10, the method further includes:

A dial-up connection is the process of establishing communication. When an IPTV terminal wants to start a PPPoE session, it must first perform a discovery phase to identify the ethernet MAC address of the opposite end and establish a PPPoE SESSON _ ID. In the discovery phase, based on the topology of the network, the client may discover multiple PPPoE servers and then select one from them, but typically the one that reacts the fastest. The discovery phase is a stateless phase, which mainly selects an access server, determines a PPP Session identifier Session ID to be established, and simultaneously obtains connection information from a peer to a peer; the PPP session phase performs standard PPP procedures. When this phase is completed, both ends of the communication know the PPPoE SESSON _ ID and the ethernet address of the opposite end, which together define a unique PPPoE session. These steps include the client broadcasting an initiation Packet (PADI), one or more PPPoE servers sending response Packets (PADO), the client sending request Packets (PADR) to selected servers, and the selected PPPoE servers sending an acknowledgement Packet (PADS) to the client. When the client receives the acknowledgement packet, it can start the PPP session phase. When the PPPoE server sends out an acknowledgement packet, it can start a PPP session.

In this embodiment, the set-top box terminal may perform dial-up connection based on PPP protocol through the ETH interface, and when a communication channel is established, set an arbitrary static IP for the ETH interface, and access an electronic Program menu epg (electronic Program guide) of IPTV, so as to complete preparation before transmitting multicast data. An electronic Program guide epg (electronic Program guide) system is used as a portal system of an IPTV service, and mainly has functions of providing a Program menu, helping a user select a favorite multicast channel, requesting a favorite video Program, and searching various information provided by the IPTV.

In the network link processing method provided in this embodiment, when a multicast adding instruction is received, a socket IP is set to be an IP of a PPPoE link, and it is determined whether multicast data is received within a first preset time period; then when the multicast data is not received in the first preset time period, resetting the socket IP as the IP of the ETH link, and determining whether the multicast data is received in a second preset time period; then, when the multicast data is not received in the second preset time period, setting the socket IP as the IP of the PPPoE link again; the network link processing method provided by the invention can simultaneously access the multicast data of the ETH link under the condition that the current IPTV terminal accesses the IPTV network by the PPPoE account number, has lower cost, can essentially solve the problem of temporary multicast data transmission of the unused link, ensures the timely and effective transmission of the data, and improves the stability of the data transmission of the IPTV terminal and the utilization rate of socket.

Based on the first embodiment, a second embodiment of the network link processing method of the present invention is proposed, and referring to fig. 3, step S10 includes:

step S11, when receiving the adding multicast command, creating a multicast socket, and setting the socket IP as the IP of the PPPoE link;

after the user starts the IPTV terminal, the user can search the content interested by the user through the EPG information system provided by the IPTV, and then order any program, namely, send a multicast adding instruction. And when the IPTV terminal receives the multicast adding instruction, establishing a multicast socket and setting a socket IP as the IP of the PPPoE link.

Step S12, join the multicast group and monitor the multicast data, and determine whether the multicast data is received within a first preset time period.

And adding a multicast group corresponding to the multicast adding instruction based on the IP of the PPPoE link, monitoring the socket and determining whether multicast data is received in a first preset time period. The first preset time period may be set by a technician, for example, set to 500ms, and then after the IPTV terminal joins the designated multicast group, the socket is monitored for 500ms to determine whether multicast data is received in this time period.

Further, in an embodiment, after step S12, the method further includes:

Generally, the digital television service is implemented by digitally compressing, encoding and modulating captured analog signals such as video and audio to form digital signals, transmitting the digital signals to a digital television terminal in various ways, receiving the digital signals by the digital television terminal, and restoring the analog signals such as video and audio to display and play through digital demodulation and decoding processing. The program source received by the digital television terminal or the set-top box is transmitted in the form of multi-segment code stream, the digital television terminal automatically acquires the program code stream information sent by the television program service provider through the digital television information when being started each time, and the program code stream information is analyzed when the digital television terminal or the set-top box receives the program code stream information.

When the IPTV terminal receives the multicast data of the PPPoE link in the first preset time period, the IPTV terminal also processes the received multicast data according to a certain method, including but not limited to the steps of identifying, verifying, analyzing, and the like.

When a judgment result that the link switching action has not been executed before is obtained, the link switching is tried. Specifically, first leave the previous multicast group, then modify the socket IP to the IP of the ETH link, join the multicast group based on the IP of the ETH link and monitor the socket data, the IP of the ETH is a static IP, and is randomly allocated in the process of dial-up connection. And when the socket IP is modified, rejoining the multicast group and monitoring the multicast data, and determining whether the multicast data is received in a second preset time period. The second preset time period may be set by a technician, for example, set to 500ms, and then after the IPTV terminal joins the designated multicast group, the socket is monitored for 500ms to determine whether multicast data is received in this time period.
