Abstract
The invention relates to the network communication field, particularly an access method, an access device and an access system. The method comprises the following steps: receiving a message of a first single board; conducting loopback processing for the message; conducting related business processing for the message; and forwarding the message to a network side or a user side through a route. The first single board is connected with a physical link of an access network; and the message enters the access network terminal processing. Through the technical scheme provided by the embodiment of the invention, the problem that the business specification is influenced by the single board is solved for a wire can be laid on the single board which is not directly connected with physical link.
Description
Technical field
The present invention relates to network communication field, relate in particular to a kind of cut-in method, device and system.
Background technology
Along with the continuous development in market, the Internet (Internet), people extend to business fields, broadband such as Internet access at a high speed, video telephone, video request programs from low speed business such as traditional phone, fax, telegrams gradually to the demand of communication.The user is also more and more higher to the requirement of business of networking, in order to satisfy user's various high-quality business experience and demand, needs special user access administration equipment, comes leading subscriber.
Simultaneously, operator commences business more flexibly for more convenient, adopts advanced networking to become indispensable means.So, in the diversified while of networking, will inevitably run into the variation that the user inserts during leading subscriber, such as, the user may pass through Ethernet, multiprotocol label switching (Multi-Protocol Label Switching, MPLS) (AsynchronousTransfer Mode, ATM) (Virtual Private Network VPN) waits the user access administration equipment that inserts for network, VPN (virtual private network) for network, asynchronous transfer mode.User access administration equipment manages, charges it and some relevant business is provided.
In the prior art scheme, the user is linked into user access administration equipment by certain network (MPLS, ATM, VPN etc.), goes up the operation that authenticates the network of reaching the standard grade and conduct interviews at the Physical board (i.e. the veneer that links to each other with physical link) that inserts.User access administration equipment has the function of termination network insertion, every function that also can provide the user to reach the standard grade authentication and management charging simultaneously.User's management information and relevant business information must all be issued on the veneer that links to each other with the access network physical link by the control aspect.Like this, just on same veneer, both realize the termination function of network insertion, and can realize every function that the user reaches the standard grade and manages again.In this scheme, though the user can realize inserting, can only with veneer that physical link is connected on reach the standard grade, the user specification of reaching the standard grade is influenced by veneer also.Particularly when the user be when entering user access administration equipment by trunk (port trunking) interface, use just more dumb.
Equally, when the network side main frame passes through certain network (MPLS, ATM, VPN etc.) access service management equipment, the address assignment of network side main frame and service management also can only be on the veneers that is connected with physical link, like this, situation for network side inserts also can exist above-mentioned problem and restriction.
