is one of the main problems of the TCP/IP transmission everywhere the Internet. The transmission cartridge holder for the total number of portions for a pass along willing not necessarily become shorter as a function of the bandwidth. Therefore, even in the near future, the while of the BACnet/WS approach for a large number of objects over the Internet will not become signifi abidetly shorter than the present level. Influence of the takings of Objects in One Access Prediction of the transmission term in the scheme-planning phase is valuable for the design of a BACnet/WS system before actual operation. This research has found that the transmission time has a strong linear correlation with the average criticize round solecism time. However, the average Ping round trip time cannot be changed by a designer of the conflicting management system for air-conditioners. Since the transmission time is obtained by dividing the pith length by the TCP/IP throughput, the transmission time is also expected to be proportional to the number of objects. Therefore, contemplation on the number of objects read in one inlet is an important design parameter for remote management systems for VRF air-conditioners.



pick up 11 shows the relationship between the number of objects NO in one access and the average access time TAa for the getValues service in the case of the client attitude of London. The client location was chosen because of the longest transmission time among the field judge locations. The values of TAa from both the theoretical calculation and field turn out were plotted against NO. The parameters of calculation were chosen as the metrical average round trip time TRTa = 0.278 and the

measured packet loss rate pa = 0.002 for the case of the clients location of London. The calculated average transmission times matched with the measurements in the field test in the cases of the number of objects NO of one, calciferol and 1000 as shown in Figure 11. The results of this calculation can be used for prior consideration on how many...If you necessity to get a full essay, order it on our website: Ordercustompaper.com
