The selection switch and kMB Ethernet interface are connected to two ports, and one of at least two ports is selected to connect to kMB Ethernet interface electrically.
Description
Technical field
The present invention relates to the Ethernet interface technology, particularly a kind of business board interface, and the method for single gigabit ethernet interface and the interconnection of dual gigabit ethernet exchange plane.
Background technology
Usually, in the system of a high reliability, Single Point of Faliure can not appear in the main node of system.System's basic hardware composition of high reliability generally includes two power boards, polylith business board.Power board mainly provides the exchange of data link, and two power boards backup each other, and constitutes two exchange planes.If the data link in the exchange plane is that (Giga-bits Ethernet, link GE) just are called the GE exchange plane to gigabit Ethernet.Such system can realize high reliability, can not cause the whole system paralysis because of the fault of power board.Fig. 1 is the model of two GE exchange plane systems, and two power boards and data link thereof constitute two GE exchange planes.Business board can be various, mainly handles various business, finishes multiple different function.
Existing technical scheme such as Fig. 2, its principle mainly is that business board connects two gigabit Ethernet exchange planes respectively with two GE interfaces.Two power boards in the system are carried out primary, spare work.Like this, when power board 1 is the main time spent, exchange plane 1 work, all business boards are connected to exchange plane 1 by gigabit ethernet interface GE1, realize the exchange of data between business board by exchange plane 1.When power board 2 is the main time spent, 2 work of gigabit Ethernet exchange plane, all business boards are connected to exchange plane 2 by gigabit ethernet interface GE2, realize the exchange of data between business boards by exchange plane 2.
The main feature of this scheme is that each business board provides two gigabit ethernet interfaces, is connected respectively on two exchange planes.But there is following shortcoming:
(1) realizes the cost height.Because each business board all will provide two gigabit ethernet interfaces, thereby has increased cost.
(2) design difficulty is big.Business board provides two gigabit ethernet interfaces, takies more veneer circuit printing plate wiring space.
Summary of the invention
The method that the object of the present invention is to provide a kind of business board interface and interconnect with the dual gigabit ethernet exchange plane to reduce cost, is saved veneer PCB layout space further.
Technical scheme of the present invention:
The method of a kind of single gigabit ethernet interface and the interconnection of dual gigabit ethernet exchange plane, the method comprising the steps of:
Two ports on one business board are connected with the gigabit ethernet interface of two power boards respectively; And
Selecting to connect on the business board port of main power board is electrically connected with a gigabit ethernet interface on this business board.
Wherein:
When two power boards carry out active and standby switching, select another port on the business board to be electrically connected automatically with a gigabit ethernet interface on this business board.
A kind of business board interface comprises a gigabit ethernet interface, it is characterized in that also comprising:
At least two ports are used for connecting respectively at least two power boards;
Selector switch is connected with described two-port at least with gigabit ethernet interface, is used for selecting and gigabit ethernet interface electric connection of at least two ports.
Wherein: selector switch is gigabit Ethernet multiplex switch or gigabit Ethernet switching network chip.
The present invention needs two gigabit ethernet interfaces to be reduced to one an original business board by multiplexing gigabit ethernet interface, has reduced system cost, and along with the business board in the system increases, the cost that system saves is just many more.Simultaneously, also reduced taking to the business board wiring space.

Fig. 5 is another structural representation of business board interface among Fig. 3.
Embodiment
Consult Fig. 3, power board 1 and power board 2 all have gigabit ethernet interface GE1, GE2...Gen, and every business board is connected with power board 2 with power board 1 respectively.Each business board only provides a physics gigabit Ethernet (being called for short GE) interface, increases the multiplex switch of a GE interface on business board, and a physics GE interface duplex is become two GE interfaces.Two GE interfaces after multiplexing link to each other with two exchange planes respectively.When power board 1 is the main time spent, 1 work of GE exchange plane, at this moment the multiplex switch of all business boards is connected to the GE interface of business board on the GE exchange plane 1, realizes the exchange of data by exchange plane 1.When power board 2 is the main time spent, 2 work of GE exchange plane, at this moment the multiplex switch of all business boards is connected to the GE interface of business board on the GE exchange plane 2, realizes the exchange of data by exchange plane 2.Realize that by the GE interface duplex GE interface of business board is connected to two exchange planes.
Consult Fig. 4, the interface of business board comprises port one and port 2, and gigabit ethernet interface is connected with port 2 with port one by the gigabit Ethernet multiplex switch, and the gigabit Ethernet multiplex switch has a control end.When control end was logical zero, the GE multiplex switch was connected to port 0 on the port one.When control end was logical one, the GE multiplex switch was connected to port 0 on the port 2.Port 0 connects the GE interface.Like this, by the logic of control multiplex switch control end, business board becomes two GE interfaces with a physics GE interface duplex.The control end of multiplex switch is to control according to the activestandby state of two power boards.Two power boards are exported an activestandby state signal respectively and are connected with business board, and business board is controlled the control end of multiplex switch according to the logic of two activestandby state signals.
Consult Fig. 5, adopt GE switching network chip to substitute the gigabit Ethernet multiplex switch in the business board, is that mainboard selects corresponding ports and gigabit ethernet interface electricity to connect by GE switching network chip according to which piece in the external power board, can realize that equally GE interface of business board is connected to two GE exchange planes.The control of switching network chip is realized by software by processor.Know the activestandby state of power board when the processor on the business board after,, make the switching network chip select corresponding ports and gigabit ethernet interface electricity to connect by the switching network chip on the software control business board.
