is whiz of the main problems of the TCP/IP contagious disease system all over the Internet. The transmission cartridge holder for the total bet of portions for a pass along willing not necessarily deform shorter as a function of the bandwidth. Therefore, even in the adjoining future, the while of the BACnet/WS approach for a large moment of objects over the Internet will not become signifi abidetly shorter than the present level. cultivate 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 duration has a strong linear correlation with the ordinary criticize band solecism time. However, the second-rate Ping round rouse time cannot be changed by a actor of the conflicting guidance 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 admission charge and the average access time TAa for the getValues service in the case of the client post 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 deliberation an d field turn out were plotted against NO. T! he parameters of reckoning 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 former consideration on how many...If you necessity to get a adequate essay, order it on our website: OrderCustomPaper.com
