An exchange platform of the machine frame type exchanger comprises exchange backboards and a plurality of exchange sub boards, wherein the exchange backboards comprise a plurality of exchange planes which are formed from a plurality of cross matrices. Each exchange sub board comprises an exchange sub plane which is formed from an exchange matrix. The exchange plane of each exchange backboard and one exchange sub board are provided with one interface. Exchange loads can be effectively disassembled by the present invention through the exchange planes, and the density of a port of the exchanger is enhanced. The present invention can be widely applied to the field of network communication.
Description
Technical field:
The present invention relates to a kind of communication equipment, relate in particular to a kind of rack switch.
Background technology:
Mostly present most Ethernet switch is the exchange at the single enterprising line data of exchange plane, uses single exchange matrix to carry out the intersection management of data link, comparatively simple in design, comparatively convenient in the management.But growing along with switch is along with the client is more and more big to network bandwidth requirement, more and more higher to the rate request of network.This just requires switch higher towards port density, and exchange capacity is bigger, and is also more and more higher to performance demands.As shown in Figure 1, single exchange plane is subjected to self to intersect the influence of matrix, with number of devices limited, and when increasing equipment, the performance of its exchange also can descend to some extent.The design of single like this exchange plane more and more has been difficult to satisfy above-mentioned requirement.
Goal of the invention:
The objective of the invention is to the single exchange plane of existing switch is expanded, a kind of switch with many exchange planes is provided, improve the total exchange capacity of switch, increase the density of port, satisfy the demand of current growing broadband network.
Rack switch of the present invention, the switching plane of this switch has a plurality of cross matrixes, and each cross matrix constitutes an exchange plane; Connect a plurality of commutators plane on each exchange plane; Directly do not link to each other between each exchange plane, but carry out mutual connection by the commutator plane; Each commutator plane can be carried out the exchange of data dynamically;
Switching plane comprises switching backplane and some exchange daughter boards, comprises the some described exchange plane that some described cross matrixes constitute on the switching backplane; Comprise the described commutator plane that a switching matrix constitutes on each exchange daughter board; One exchange plane of every exchange daughter board and switching backplane has interface.
All there is connecting interface on above-mentioned each exchange plane and each commutator plane.
Each exchange plane is established calibrating chip and chip for driving.Each exchange plane is configured and manages by an ADMINISTRATION SUBSYSTEM.
The interface of each commutator plane and exchange plane is established calibrating chip and chip for driving.Each commutator plane all has ADMINISTRATION SUBSYSTEM, and this exchange plane is configured and manages.
The present invention can decompose the load of exchange effectively by a plurality of exchange planes, improves the density of switch ports themselves.

Embodiment:
The present invention expands the single exchange plane of existing switch.As shown in Figure 2, as an exchange plane, the exchange plane of expanding on its basis is as a commutator plane with original single intersection matrix.The present invention designs a plurality of intersection matrixs on a switching backplane, each intersection matrix is an exchange plane, and each exchange plane goes out an interface to a commutator plane, inserts the equipment of the swap data of wanting on the commutator plane.
As shown in Figure 3, the switching plane of switch of the present invention comprises switching backplane and each exchange daughter board, wherein switching backplane comprises four exchange planes, on each exchange daughter board a commutator plane is arranged, and realizes the exchanges data between each switching equipment in the commutator plane.
1, switching backplane:
On switching backplane, have 4 intersection matrixs, each intersection matrix has 8 interfaces, an interface of each intersection matrix connects an exchange daughter board, each interface of the present embodiment is the bidirectional high speed bus of 32 bit wides, through adding check code behind the calibrating chip, prevent that data are in the process of transmitting as can have the function of automatic repeating transmission after mistake occurring, data are carried out exchanges data through chip for driving and exchange daughter board then, and are no problem but sample can guarantee transfer of data is long on big backboard distance.On switching backplane, also have an ADMINISTRATION SUBSYSTEM,, 4 intersection matrixs are configured and manage by pci bus based on the single-chip microcomputer of a POWER PC.
2, exchange daughter board
1 intersection matrix is arranged on the exchange daughter board, the matrix that intersects has 8 interfaces, wherein 4 interfaces connect the equipment that will carry out exchanges data, other 4 interfaces connect an intersection matrix on the switching backplane respectively, realize striding the exchanges data on commutator plane like this, the same with switching backplane, calibrating chip and chip for driving are no problem to guarantee transfer of data is long on big backboard distance having added equally on the data channel of last backboard, and the data channel in the veneer does not add calibrating chip and chip for driving because the distance of transmission is shorter.Same exchange daughter board also has an ADMINISTRATION SUBSYSTEM, based on the single-chip microcomputer of a POWER PC, by pci bus the intersection matrix is configured and manages.
Each exchange plane is actually by the commutator plane and links together like this.Equipment exchanges data each other on same commutator plane, it doesn't matter with the commutator plane of exchange plane and other, can not influence their exchanges data, and the performance of switching network is very good like this.By the transferring of exchange plane, can decompose the load of exchange effectively during exchanged between equipment data on the different commutator planes, improve the density of port.
As Fig. 3, used 4 intersection matrixs on the switching backplane, each intersection matrix has 8 interfaces, and an interface of each intersection matrix connects a commutator plane, can connect 4 * 8=32 equipment so altogether.Wherein each interface is the bandwidth of 4G, like this total exchange capacity of entire equipment one total 128G.Can satisfy the exchange requirement of most rack-mount unit.
Be understandable that; under enlightenment of the present invention; the designer can design different exchange daughter boards; to satisfy the different interface of different switching networks; and use the requirement that different exchange daughter boards can adapt to different network environments and different interfaces to equipment in the use; but all should be reproduction, belong to protection scope of the present invention the present invention program.
