Abstract
The invention discloses a kind of interchanger that can arbitrarily change transport media type, including master control borad, backboard and subcard, the backboard that master control borad is connected to by ethernet standard interface, backboard to be connected to subcard by ethernet standard interface.Master control borad includes MAC layer and the first backplane interface.Backboard includes master control plate interface and daughtercard interface.Subcard includes the second backplane interface, physical layer and ethernet medium interface.When Network Transfer Media changes, it is only necessary to which the adaptation of transmission medium can be completed by changing corresponding subcard, without changing whole interchanger, reduce networking and improvement cost.
Description
Technical field
The present invention relates to the interchanger in communication field, more particularly to be suitable for demand flexible for one kind
Change the interchanger of transport media type.
Background technology
At present, known interchanger, all interfaces are all fixed, once from manufacturer
After dispatching from the factory, transport media type will be unable to change.But when present high speed information develops
In generation, as the basis of information transfer, ethernet network is also also in high speed development.Transmission medium
Also evolved from traditional cable transmission to optical cable transmission.But meanwhile current terminal device, base
Based on this is accessed with cable, while also there is optical cable access.In the various network of this transmission medium
In, may be by the interface of the switch device caused in network once transmission medium changes
It is inapplicable, so as to need to purchase new switch device again.So existing constant transmissions are situated between
The adaptability when interchanger of matter type changes to Network Transfer Media worse and worse, increases
Networking and the cost of transformation.
The content of the invention
In order to improve adaptability of the interchanger in network complicated and changeable, the invention provides one
Kind can arbitrarily change the interchanger of transport media type.
To reach above-mentioned purpose, embodiments of the invention adopt the following technical scheme that：
A kind of interchanger that can arbitrarily change transport media type, including master control borad, backboard and son
Card；The backboard that the master control borad is connected to by ethernet standard interface, the backboard pass through ether
Net standard interface is connected to subcard.
According to one aspect of the present invention, the master control borad includes MAC layer and first
Backplane interface；The MAC layer passes through ethernet standard interface and the first backplane interface
It is connected.
According to one aspect of the present invention, the backboard includes master control plate interface and daughtercard interface；
The master control plate interface is connected by standard ethernet data channel with daughtercard interface.
According to one aspect of the present invention, the subcard include the second backplane interface, physical layer and
Ethernet medium interface；Second backplane interface passes through ethernet standard interface and physical layer phase
Even, the physical layer is connected with ethernet medium interface.
The advantages of present invention is implemented：
The present invention passes through the MAC layer (MAC) and physical layer (PHY) interchanger
And the standard ethernet data channel between them reasonably separates.Pass through physical layer simultaneously
(PHY) diversity of achievable transmission medium, the subcard of different transmission mediums is designed.Together
When, using the medium independence of ethernet standard interface, complete by changing subcard to reach
The purpose of the transmission medium of more transducer switching system.
The present invention is when Network Transfer Media changes, it is only necessary to changes corresponding subcard
The adaptation of transmission medium can be completed, without changing whole interchanger, network is reduced with this
Construction and improvement cost.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, below will be to embodiment
In the required accompanying drawing used be briefly described, it should be apparent that, drawings in the following description
Only some embodiments of the present invention, for those of ordinary skill in the art, do not paying
On the premise of going out creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the general frame schematic diagram of the present invention.
Fig. 2 is the master control borad schematic diagram of the present invention.
Fig. 3 is the backboard schematic diagram of the present invention.
Fig. 4 is the subcard schematic diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present invention
Case is clearly and completely described, it is clear that described embodiment is only the present invention one
Divide embodiment, rather than whole embodiments.It is general based on the embodiment in the present invention, this area
The every other embodiment that logical technical staff is obtained under the premise of creative work is not made,
Belong to the scope of protection of the invention.
As shown in figure 1, the interchanger that can arbitrarily change transport media type of the present invention, by leading
Control plate 1, backboard 2, subcard 3 form.The back of the body that master control borad 1 is connected to by ethernet standard interface
Plate 2.Backboard 2 is connected to subcard 3 by ethernet standard interface.Master control borad 1 is primarily used to
Data exchange.Backboard 2 is primarily used to the interface channel between master control borad 1 and subcard 3.Subcard 3
The conversion of various transmission mediums is mainly realized by physical layer (PHY).
As shown in Fig. 2 master control borad 1 is by MAC layer (MAC) 101 and the first backboard
Interface 102 forms.MAC layer (MAC) 101 passes through ethernet standard interface and
One backplane interface 102 is connected.
As shown in figure 3, backboard 2 is made up of master control plate interface 201 and daughtercard interface 202.It is main
Control plate interface 201 is connected by standard ethernet data channel with daughtercard interface 202.Backboard 2
Data communication between master control borad 1 and subcard 3 provides physical channel.
As shown in figure 4, subcard 3 is by the second backplane interface 301, the He of physical layer (PHY) 302
Ethernet medium interface 303 forms.Second backplane interface 301 and physical layer (PHY) 302 are logical
Ethernet standard interface is crossed to be connected.Physical layer (PHY) 302 and the phase of ethernet medium interface 303
Even, different types of transmission medium is provided for subcard.Ethernet medium interface 303 carries for equipment
Connected for different media.Subcard 3 can realize light according to different physical layers (PHY) 302
Two kinds of Ethernet interfaces of transmission medium and electrical transmission media.
In summary, the present invention data exchange and transmission medium interface separately on different boards
And by backboard but be not limited to backboard carry out data connection, by change transmission medium interface board come
The transport media type of interchanger is changed, networking and maintenance cost can be reduced.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is simultaneously
This is not limited to, any those skilled in the art is in technology model disclosed by the invention
In enclosing, the change or replacement that can be readily occurred in, it should all be included within the scope of the present invention.
Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
