Detailed Description

The present invention will be further described with reference to the accompanying drawings.

A terminal full-port blind plugging method for opening multi-service based on gigabit network includes the following steps: (S1) the optical modem automatically recognizing the service and distinguishing the IPTV from the broadband; (S2) the router automatically identifies the WAN/LAN port.

In the step (S1), the optical modem analyzes each DHCP message sent by the drop access terminal, analyzes and judges the Option 60-carrying messages, and automatically classifies and sends the identified services.

In the step (S2), the router detects the port, firstly, it defines the port with DHCP request as LAN, secondly, it initiates DNS request to determine WAN, and for initiating PPPoE simulation test which can not be identified yet, WAN/LAN identification and conversion are realized through the above three steps.

Analyzing and judging the message carrying the Option60, if the plaintext contains SCITV or the ciphertext contains '@ ITV', judging the service on the MAC to be an IPTV service, and transferring all the MAC streams to corresponding channels; if the Option60 message has neither 'SCITV' nor '@ ITV' identification, then the service on the MAC is judged to be public network service, an optical modem private network address is allocated to the MAC, and all the MAC streams are uploaded through a private network segment.

Through blind plugging of the optical modem, the optical modem automatically identifies services, single-network multiplexing is realized (one network needs to simultaneously open broadband and ITV services), and in an embodiment, blind plugging of an optical modem port and blind plugging of a router port are simultaneously realized.

The router has the same capability of automatically identifying services as the optical modem on the basis of WAN/LAN port self-adaptation, realizes flexible and convenient networking by adding the router, can open two services of broadband and IPTV and has gigabit service capability at the same time. The optical modem does not need redundant ports, namely only one port in the optical modem is needed to realize the automatic identification of IPTV and broadband, the number of the ports of the existing optical modem is reduced, and meanwhile, the ports can support gigabit broadband.

The optical modem port and router port traffic is automatically identified.

Automatic port identification for optical modems:

1. identifying the service to distinguish between IPTV and broadband: the optical modem analyzes each DHCP message sent by the downlink access terminal, analyzes and judges the message carrying the Option60, and if the plaintext contains SCITV (case indiscriminate) or the ciphertext contains @ ITV (case indiscriminate), the service on the MAC is judged to be IPTV service, and all MAC streams are transferred to a VLAN 43 channel; if the Option60 message has neither 'SCITV' nor '@ ITV' identification, then the service on the MAC is judged to be public network service, a 192.168.XXX.XXX optical modem private network address is distributed to the MAC, and all the MAC streams are uploaded through a private network segment. 2. The router part identifies the WAN/LAN: the router detects the port, firstly defines the port with DHCP request as LAN, secondly initiates DNS request to determine WAN, and realizes WAN/LAN identification and conversion through the three steps for initiating PPPoE simulation test which can not be identified, thereby realizing blind plugging capability.

Automatic identification of router insertion ports:

1. identifying the service to distinguish between IPTV and broadband: analyzing each DHCP message sent by the downlink access terminal, analyzing and judging the message carrying the Option60, if the plaintext contains SCITV (case indiscriminate) or the ciphertext contains @ ITV (case indiscriminate), judging that the service on the MAC is IPTV service, and transmitting the IPTV service to the WAN port through the two layers of the LAN port; if the Option60 message has neither 'SCITV' nor '@ ITV' identification, the service on the MAC is judged to be public network service, a 192.168.XXX.XXX router private network address is allocated to the MAC, and all the MAC streams are uploaded through a private network segment. 2. The router automatically identifies the WAN/LAN: the router detects the port, firstly defines the port with DHCP request as LAN, secondly initiates DNS request to determine WAN, and realizes WAN/LAN identification and conversion through the three steps for initiating PPPoE simulation test which can not be identified, thereby realizing blind plugging capability.

In an embodiment, the router adopts an AP mode, works in a two-layer bridge mode, directly transparently transmits a set top box DHCP message (identified as an IPTV service through IPTV user account information carried by option 60), and achieves a double blind insertion effect of the optical modem and the router. The networking and implementation is shown in fig. 3.

In another embodiment, the router adopts a routing mode, the IPTV set-top box is inserted into any LAN port of the router in a blind manner, after the router completes automatic identification of the WAN port and the LAN port, an interface (LAN) of the set-top box access router and the WAN port complete automatic negotiation setting in a two-layer bridge mode, i.e., a DHCP message of the set-top box can be transmitted, and the rest LAN ports and the WAN port perform message forwarding normally, so that the router is used for broadband services to access network devices such as a computer host and the like. The router WiFi is used for connecting various network terminals. Lan, port wan; the networking and implementation is shown in fig. 4.

The optical modem realizes blind plugging of the LAN port, and solves the problem of service failure caused by wrong plugging of a network cable into the LAN port (broadband service equipment such as a computer, a router and the like is plugged into an IPTV interface, and an IPTV set-top box is plugged into the broadband interface); the router opens the IPTV access capability, realizes the flexibility of user home networking and network cable arrangement, and the speed in the local area network is increased from 100Mbps to 1000Mbps, thereby meeting the networking requirements of gigabit broadband products.

The router can work in an AP mode or a routing mode, a WAN port and a LAN port are automatically identified in the routing mode, once the IPTV set top box is accessed, the WAN port is automatically marked as the LAN port through message identification, and the LAN port and the WAN port negotiate to be a bridge mode communication mode, so that the two-layer mode transparent transmission of the IPTV message is realized.
