Embodiment
Be that example is done detailed description to content of the present invention with IPTV set-top box service distributing below.
As shown in fig. 1, for adopting multi-protocols terminal network topological diagram of the present invention.IPTV set-top box 101 is as terminal equipment, by the ethernet port connection broadband network modulator-demodulator 102 of a physics.Described physical port is divided into two logical subinterface, or be called professional sub-interface, be respectively 1 work song port and 2 work song ports, described modulator-demodulator links to each other with access device 103 by the circuit that carries PPPoE data and common Ethernet data simultaneously, and described access device is up to link to each other with the IPTV server zone 106 that is connected by kilomega network switch 105 with access server respectively.Because the IPTV server zone is placed on access server (BRAS) front, the IPTV set-top box adopts the PPPoE access authentication, and obtains the IP address, and the IPTV Business Stream will be without access server (BRAS).
According to said structure, the shunting process of data service is as follows:
At first an Ethernet physical interface with the IPTV set-top box is configured to two logical subinterface, promptly construct the entity of two logical subinterface by connecting port on the upper layer software (applications) being, with same Ethernet physical interface binding, and the IP address of two sub-interfaces is identical, and packet encapsulation agreement difference.Two logical subinterface are designated 1 work song interface and 2 work song interfaces respectively, 1 work song interface operation PPPoE agreement, and 2 work song interfaces then still adopt common Ethernet encapsulation.After being specially user's start, IPTV set-top box software system can be that last connecting port is created two logic interfacings automatically, promptly on physical interface layer, create the first level logical interface again, and it is all related downwards with same physical interface, data that are used for receiving and dispatching the PPPoE encapsulation, another is used for receiving and dispatching the data of Ethernet encapsulation, be masked as logic interfacing 1 and logic interfacing 2 respectively, 1 work song interface operation PPPoE agreement begins dialing, and authenticate by PPPoE, with access server (hereinafter to be referred as: BRAS) set up a PPPoE link, be assigned to an IP address, be exemplified as " 192.168.1.10 ", 2 work song interfaces are come the IP address multiplex of 1 work song interface, promptly the IP address of 2 work song interfaces is configured to " 192.168.1.10 " automatically, but described 2 work song interfaces do not move the PPPoE agreement, and adopts the Ethernet encapsulation.
Carry out routing in network layer by Business Stream, if the Business Stream of IPTV, then with non-PPPoE logical subinterface 2 communications, other Business Streams then adopt the PPPoE sub-interface.As shown in Figure 2, in IPTV set-top box protocol stack, application layer will be to the line identifier that flows to of different business, thereby can carry out routing to different Business Streams according to sign at the IP layer, the IPTV Business Stream will adopt non-PPPoE sub-interface 2 communications, and other Business Stream then adopts 1 communication of PPPoE sub-interface.Different business stream adopts various objectives IP address to identify, and in Business Stream routing policy table, purpose IP address and the registering IP address IP data of mating are exactly the IPTV Business Stream to application layer so with the purpose IP address registration of IPTV Business Stream.Thereby the IPTV business can not sent through the logical subinterface of PPPoE encapsulation but directly encapsulate logical subinterface from Ethernet.
When the IPTV set-top box will be carried out service communication, the IPTV application layer is registered to the purpose IP address or the subnet address of communication in the Business Stream routing policy table, the IP packet of IPTV business will be according to the Business Stream routing policy, select IPTV media gateway 192.168.1.100 for use, obtain the ethernet hardware address of gateway by ARP (address resolution protocol), send from 2 work song interfaces then, rather than carry out the PPPoE encapsulation and go out from 1 work song interface; Like this, the IPTV Business Stream will can not pass through access server (BRAS), but directly by the IPTV media gateway, IP address for example " 192.168.1.100 " communicates.
For example the user wants to connect electric program menu (EPG) server, and the IP address is " 201.1.1.1 "; According to routing policy table configuration, the purpose IP address of business datum belongs to the 201.1.1.0 network segment, so network layer protocol modules can adopt business datum the Ethernet encapsulation, sends from 2 work song interfaces, is routed to the IPTV server zone by the IPTV media gateway; And, will be routed to No. 2 logical subinterface of set-top box by the IPTV media gateway from the data that the IPTV server zone is returned, arrive set-top box IPTV business application module at last;
Other service communication of IPTV set-top box, such as view Internet web website, receive Email etc., according to the configuration of routing policy table, the purpose IP address of business datum belongs to the non-201.1.1.0 network segment, therefore network layer protocol modules can adopt business datum the PPPoE encapsulation, from 1 work song interface, send by the PPPoE link, arrive the destination by BRAS, the data of returning on the Internet also with the PPPoE link of BRAS, arrive set-top box 1 work song interface.
In addition, the user also can be provided with the function that whether enables the multi-protocols service distributing, if do not use this function, then the IPTV set-top box is operated in conventional state, be that all be encapsulated in PPPoE frame the same with other data of IPTV transmitted, be used in the situation that the IPTV server is placed on the BRAS upstream ends.
More than multi-protocol network terminal service shunting method provided by the present invention and device thereof are described in detail, used specific case herein principle of the present invention and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
