The above-mentioned upper level server of step S62 receives control result, corresponding higher level's destination server is searched out according to the destination address in routing table and session id, and control result is returned to its higher level's destination server: in this step, the upper level server of end service device receives control result, search out corresponding higher level's destination server (namely searching out the request source of corresponding above-mentioned control result) according to the destination address in routing table and session id, and this control result is returned to its higher level's destination server.
Step S63 judges the session whether end service device and its higher level's destination server do not complete in addition: in this step, judges the session whether end service device and its higher level's destination server do not complete in addition, if the result judged is yes, then performs step S64; Otherwise, perform step S65.
Step S64 proceeds session, waits for setting-up time: if the judged result of above-mentioned steps S63 is yes, i.e. the session that do not complete in addition of end service device and its higher level's destination server, then perform this step.In this step, proceed session, return step S63 after waiting for setting-up time and proceed to judge.
Connection between step S65 disconnected end server and its higher level's destination server: if the judged result of above-mentioned steps S43 is no, then perform this step.In this step, the connection between disconnected end server and its higher level's destination server.
After step S66 current server receives and controls result, corresponding higher level's destination server is searched out according to the destination address in routing table and session id, and control result is returned to its higher level's destination server, disconnect the connection with its next stage server: in this step simultaneously, after current server receives and controls result, corresponding higher level's destination server is searched out according to the destination address in routing table and session id, and control result is returned to its higher level's destination server, disconnect the connection with its next stage server simultaneously.
Control result returns according to the mode of step S66 by step S67 step by step, till turning back to top server: in this step, control result is returned step by step according to the mode of above-mentioned steps S66, until control result is turned back to top server.It is worth mentioning that, the return path of above-mentioned control result is obtained by routing table.Just achieved by cascade like this and control result is returned client.
In order to be described in detail to said method, son of illustrating below is described.As shown in Figure 4, in Fig. 4 be the present embodiment cascade server data flow diagram.In Fig. 4, such as customer end A 1 needs the switch of Long-distance Control smart machine N3 to disconnect, but customer end A 1 cannot realize direct-connected with smart machine N3, control command (request instruction) need successfully could be sent by the such paths of server M1-server M2-server M3-smart machine N3, at this moment, server M1 is just equivalent to above-mentioned top server, and server M3 is just equivalent to above-mentioned end server.At this moment, conveniently realize by said method, its realization is as follows:
Customer end A 1 sends the request instruction in a band cascade path to server M1, as: Requst:1001:11.1.11.4:503/12.2.12.5:502/N3:off; Wherein, Request is request, and 1001 is session id, and 11.1.11.4:503/12.2.12.5:502 is cascade path, and smart machine N3 is wanted in N3 representative, and off is shutoff operation.
After server M1 receives above-mentioned request instruction, by resolving request instruction, there is cascade path in discovery, create and preserve routing table (routing iinformation), simultaneously to server M2(11.1.11.4:503) initiate to connect, and Forward-reques instruction Request:1001:12.2.12.5:502/N3:off, this is the request instruction being transmitted to server M3 by server M2, eliminates the IP address of server M2 self in this request instruction.In the present embodiment, routing iinformation comprises order source, subordinate's destination address and session id; In the present embodiment, routing iinformation is also referred to as routing table.After server M2 receives request instruction Request:1001:12.2.12.5:502/N3:off, there is cascade path in same discovery, creates and preserve routing iinformation, initiates to connect and Forward-reques instruction Request:1001:N3:off to server M3 simultaneously.
After server M3 receives request instruction Request:1001:N3:off, control is performed to smart machine N3, and obtain controlling result, control result is returned to server M2 simultaneously.Such as: control result is Answer:1001:1, wherein, Answer representative is answered, and 1001 represent session id, and 1 represents fill order success, and 0 represents fill order failure.After server M2 receives and controls result, know that controlling result returns according to Answer command header, so according to session id and destination address from the routing table of preserving, search out corresponding higher level's destination server M1, result is returned to server M1, judge that having other or not with server M3 does not complete session simultaneously, when the session do not completed, initiatively disconnect the connection with server M3.In like manner, control result is returned to customer end A 1 after receiving and controlling result by server M1, and disconnects the connection with server M2.At this moment, customer end A 1, by Cascading Methods, successfully realizes inter-network end Long-distance Control smart machine N3.
It is worth mentioning that, one station server may need to do repeatedly cascade transmit work simultaneously, likely the operation of different clients to different intelligent equipment, also be likely the operation of same client to different intelligent equipment, when control result returns, have to pass through routing table, accurately could find order source, accurately return control result.
