Specifications

The efficiency of a network can be influenced by factors such as data throughput speed, the maximum distance between network devices, and the time delay (latency) during data transfer.

Bandwidth

Consider the following example of the Simphony Client Application Loader (CAL) on a Wide Area Network (WAN):

When new client applications or support files are available, the CAL sends the new set of files from the enterprise application server to the clients.

A standard Simphony version service host CAL package is usually about 50 megabytes (MB) in size, so a property with 100 workstations (clients) needs to download 5000 MB of data through the WAN.

When the network bandwidth of a property cannot support simultaneous requests made by numerous clients, properties might experience bandwidth bottlenecks.

To calculate the bandwidth by workstation:

• Number of workstations = W
• W x 0.171 Mbps = Total workstation bandwidth during normal operations.
• W x 8 Mbps = Total workstation bandwidth when performing a reload of a workstation's database.

Minimum: 8.5KB/sec per client. The CAL client expects the application server to respond to each file block request within 60 seconds (512KB / 60sec = 8.5KB/sec). Prior to CAL client 146, the package installation fails when this minimum cannot be met.

Maximum: None imposed by the CAL client. External factors, such as network latency and bandwidth between the application server and workstation, influence the maximum rate of transfer.

Distance

• Do not exceed the maximum distance allowed for your cabling.

• Calculate the maximum allowable distance for the final connection between the wall jack and the device.

Latency

It is recommended to install the software in the cloud environment that offers the lowest possible latency to the site, if possible.
