As from the foregoing, communication means of the present invention can satisfy the transparent requirement of dedicated system, does not move various general procotols, adopts the privately owned communication means of point-to-point, guarantee the fail safe of dedicated system, also realized the communication of data between the equipment and the circular of state simultaneously.
Description of drawings
Fig. 1 is to use the structural representation of the dedicated system of the inventive method;
Fig. 2 is the flow chart of the inventive method.
Embodiment
Be the exclusive data treatment system of present embodiment as shown in Figure 1, this system blocks the given traffic streams on the internet, judges then, the business that meets some condition is held back, and other professional continuation are transmitted.Detailed process is:
RTA equipment (RTA, RTB are the equipment code names) blocks the given traffic streams on the internet, sends to RTB equipment; RTB equipment is according to the port of service message, and characteristics such as address are carried out the equilibrium shunting, send to the service message processing server; After the service message processing server is judged service message, continue if desired to transmit, then send to RTB equipment; RTB equipment is issued RTA equipment after receiving the message that the service message processing server sends out, and RTA equipment is forwarded on the internet again.
According to the flow process of the data packet messages of equipment, RTB equipment is the second line of a couplet equipment of RTA equipment, and the service message processing server is the second line of a couplet equipment of RTB equipment.Correspondingly, RTA equipment is the first line of a couplet equipment of RTB equipment, and RTB equipment is the first line of a couplet equipment of service message processing server.A RTB equipment in the present embodiment can connect a plurality of RTA equipment, also connects a plurality of Service Process Server simultaneously, and RTA equipment and Service Process Server only are connected to a RTB equipment.Adopt Ethernet interface to realize that point-to-point connects between each equipment, the point here is meant RTA equipment, the concrete port of RTB equipment or service server.
This system is a transparent system, and so-called transparent this system that is meant does not move general procotol, and therefore the equipment that is connected with this system can't utilize general procotol to find the existence of this system.Adopt the method for present embodiment to communicate between the equipment in this system.
As shown in Figure 2, above-mentioned data handling system adopts following steps to realize data communication and state circular when work:
After step 120, service message processing server started normally, beginning was to RTB equipment transmit status message; The form of present embodiment state circular message is as follows:
Wherein, Ethernet message protocol field " 0800 " is revised as " 0000 " sign as state message, can certainly be revised as " 1111 " or other data.Other field of state message can arbitrarily be specified.
The form of state circular message is as follows:
After step 150, RTA equipment are received the service message of given traffic streams from Internet, send to RTB equipment after service message encapsulated Directional Sign, the data message form between RTA equipment and the RTB equipment is as follows:
MAC_DA wherein refers to the target MAC (Media Access Control) address that exists in the former message, and MAC_SA refers to corresponding source MAC.And with preceding 4 Directional Signs that are revised as service message in the Ethernet message protocol field (0x0800).Directional Sign be used to indicate this service message come to and whereabouts, promptly receive and send two ports of this service message.
Wherein further with the 5th in the Ethernet message protocol field (0x0800) to the 8th numbering that is revised as the RTA equipment of handling this service message.
After step 180, RTB equipment are received the service message of service message processing server transmission, from service message, remove the RTA device numbering of this message, send to corresponding RTA equipment then; Wherein the data message form between RTB equipment and the RTA equipment is:
As can be seen, data communication and the state circular of the foregoing description in order to have realized point-to-point in data handling system, adopted following privately owned communication means:
Second line of a couplet equipment such as service message processor, RTB equipment are with specific several the signs as state message in the ether network packet, to first line of a couplet equipment timed sending state messages such as RTB equipment, RTA equipment; The quantity of the state message that first line of a couplet monitoring of equipment is received if be lower than desired value, is then thought and the second line of a couplet equipment room generation communication failure that sends this state message; And
When RTA equipment sends service message to RTB equipment, with in the ether network packet specific several as Directional Sign, realize record to each data message direction; When RTB equipment sends service message to the service message processing server, with in the ether network packet specific several as device identification, realize record to each data message source.
Therefore, the foregoing description is to increase Directional Sign and device numbering in general Ethernet data message, and revises protocol fields as privately owned communication meanss such as state messages, has realized the data communication and the state circular of point-to-point in data handling system.Need to prove, the concrete data handling system that above-mentioned communication means is not limited to provide among the embodiment, the transparent system that adopts private method to carry out point to point link for needs can adopt, and this moment, concrete treatment step may be different with the foregoing description.
Communication means in the foregoing description can also be done some conversion, for example, realizes above-mentioned functions by other Bit positions of revising protocol fields.Perhaps, also can realize above-mentioned function by between Ethernet heading and IP message, increasing bed course (as increasing a field).
And for example, if when the first line of a couplet in the system and second line of a couplet equipment adopt One-to-one communication, do not need the source of record data message.
And for example, the transparent data treatment system also can have only two-stage, promptly may not comprise the RTB equipment that is used to shunt among the embodiment.Correspondingly,, need only encapsulate the direction sign, issue corresponding service message processing server, beam back source device by former encapsulation again after the service message processing server is finished dealing with and get final product for pending service message.
