Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Fig. 1 is the structural representation of remote network topological connector one embodiment of the present invention.As shown in Figure 1, the embodiment of the invention provides a kind of remote network topological connector (Remote Network TopologyConnection; Hereinafter to be referred as: RNTC), comprising: a uplink port 11, several remote ports 12 and a control module 13, wherein uplink port 11 connects external equipment by network; Remote port 12 connects local device; Control module 13 is used to control uplink port 11 and intercoms mutually with remote port 12.
In embodiments of the present invention, uplink port 11 is for connecting the port of another RNTC of far-end, and remote port 12 is for connecting the port of local device.Control module 13 intercoms with remote port 12 mutually by control uplink port 11, to carry out long-range topological transformation.
The remote network topological connector of the embodiment of the invention, intercom mutually with remote port by the control uplink port, solved that main laboratory plugs the defective that the device port netting twine causes device damage repeatedly in the prior art, seamless bridge joint and fast network change in topology between the tele-experimentation chamber have been realized, avoid plug device port netting twine, prolonged the useful life of equipment.
Fig. 2 is the structural representation of another embodiment of remote network topological connector of the present invention.As shown in Figure 2, on the basis of technique scheme, control module 13 also is used to control remote port 12 when receiving the message of local device transmission, add remote identification (REMOTE_ID) to this message, and being sent to uplink port 11, this remote identification is used for the remote port 12 of unique this RNTC of sign.
In addition, control module 13 also is used to control uplink port 11 when receiving the message that external equipment sends, and deletes the remote identification in this message, and be sent to remote identification the remote port 12 of unique sign.
Fig. 3 is the message handling process schematic diagram in the remote network topological connector of the present invention.As shown in Figure 3, original message enters RNTC No. 1 from the port of REMOTE_ID=X, and message is transmitted on network be coupled with the head of REMOTE_ID=X in No. 1, RNTC after; After RNTC receives this message No. 2, delete the head of message, and the port of final message from REMOTE_ID=X produced.
In the embodiment shown in Figure 2, each remote port 12 all has a sign, is called REMOTE_ID.REMOTE_ID is unique for remote port 12, if a REMOTE_ID has been configured to a remote port 12, so follow-up other remote ports 12 can not re-use this REMOTE_ID.A RNTC can dispose a plurality of remote ports 12.
RNTC has VLAN (Virtual Local Area Network; Hereinafter to be referred as: VLAN) function, each VLAN has a sign, is called VLAN_ID.Remote port 12 must join on RNTC among the VLAN that VLAN_ID is REMOTE_ID.
Each remote port 12 can only intercom mutually with uplink port 11, can not intercom mutually with other general ports or other remote ports 12.
Uplink port 11 carries an ID at least to the message that remote port 12 sends, and the outermost ID of message is considered to REMOTE_ID.Like this, message is shelled the ID head at RNTC,, deletes outermost sign that is, and is forwarded to REMOTE_ID on the remote port 12 of this ID.
Further, control module 13 can also comprise: first control unit 21.This first control unit 21 is used to control uplink port 11 and intercoms mutually with any remote port 12.
Further, control module 13 can also comprise: second control unit 22.This second control unit 22 is used to control blocking-up mutually between any remote port 12.
In addition, control module 13 can also comprise: the 3rd control unit 23.The 3rd control unit 23 is used to control remote port 12 and intercoms mutually with central processing module (that is the CPU of RNTC).Control module 13 can also comprise: the 4th control unit 24.The 4th control unit 24 is used to control uplink port 11 and intercoms mutually with central processing module.Make CPU can manage uplink port 11 and the remote port 12 among the RNTC.
The remote network topological connector of the embodiment of the invention, intercom mutually with described remote port by the control uplink port, solved that main laboratory plugs the defective that the device port netting twine causes device damage repeatedly in the prior art, seamless bridge joint and fast network change in topology between the tele-experimentation chamber have been realized, avoid plug device port netting twine, prolonged the useful life of equipment.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
