Fig. 5 b is used for illustrating the accompanying drawing that is applicable to transmission judgement table of the present invention.As shown in the figure, in transmitting the judgement table,, each device characteristics identifier word transmits identifier word information but all being set with intrinsic network.For example, but transmit identifier word, be set at SSSS corresponding to the network of device characteristics identifier word UUID; When the SSSS of such setting followed the networking transmission identifier word that receives identical, local network device was sent to the individual features data of UUID indication other local network device.
Below, with reference to Fig. 6, to of the present invention another in local network, be used for the network transfer approach of judgment device performance data and describe.
As shown in FIG. 6, this method is made of following several stages, that is: the device characteristics data flow that in local network device, transmits, by the wire/wireless passage through stage (S600) of receiving of monitoring; The stage (S610) that the device characteristics data flow that receives is transmitted; But from the device characteristics data fetch equipment characteristic identifier word that transmits stage (S620) with the corresponding network transmission of device characteristics identifier word identifier word; But transmit identifier word to what read with the corresponding network of device characteristics identifier word, but transmit the stage (S630) that identifier word compares with the network that is recorded in transmission judgement table; According to result relatively, to corresponding with the device characteristics identifier word that reads, whether the network of performance data transmits the stage of judging (S640).
By the transmission determination methods that these stages form, at first utilize the local network cable of optical cable or coaxial cable etc. connecting a plurality of local network devices; Device characteristics data flow from these local network devices send will receive (S600) by monitoring.
At this moment, the device characteristics data flow that receives is for example in the network of the utilization of setting up illegally based on the UPNP of IP, the device characteristics data flow that receives is the ad data stream of local network device, or the response traffic that sends according to the requirement of local network control appliance; But the device characteristics identifier word of Shi Yonging and network transmit identifier word in the present invention, are the information sets that is stated from this data flow, and other local network devices on the cable receive from being connected.
Then,, will transmit the device characteristics data flow (S610) that receives so, but and read the device characteristics identifier word and the network that are stated from the device characteristics data flow and transmit identifier word (S620) if received device characteristics data flow (S600).
Then, but will transmit identifier word to device characteristics identifier word that reads and network corresponding with it, transmit and may compare (S630) by identifier word with being set in the device characteristics identifier word and the network that transmit the judgement table successively, and whether (S640) that judge that performance data corresponding to the device characteristics identifier word transmits according to result relatively.Its deterministic process is as follows.
At first, the identical device characteristics identifier word of device characteristics identifier word that reads is followed in search in transmitting the judgement table; If detect identical device characteristics identifier word, but the network that goes so to read the detected device characteristics identifier word of coupling transmits identifier word, transmits identifier word with the network that reads then and compares.
Result relatively, if but the network that is detected by transmission judgement table transmits identifier word, but different with the network transmission identifier word that transmits by network, will not allow so send the device characteristics data of indicating by the device characteristics identifier word.
In addition, in contrast, if but the network that is transmitted by network transmits identifier word, but to transmit identifier word identical with transmitting network that the judgement table detects, so just allows send device characteristics data by the indication of device characteristics identifier word, and finish the present invention whereby.
