crossWAN online allows all Across functionalities to be used via the Internet (only in connection with the crossVPN Server). Working with crossWAN online is identical to working in the company network with crossLAN.
Since situations critical to security can arise when the entire range of Across functions is provided via the Internet, crossWAN online should only be used in closely administrated environments.
The performance of crossWAN online depends on the transmission rate of your data line. For any related questions, please contact our support:
- When using crossWAN online, two aspects in particular must be taken into account:
- the bandwith of the available Internet connection
- the latency of the Internet connection, whereby latency is of greater importance.
Nowadays, the bandwidth of the Internet connection usually does not constitute a critical or impeding factor, as broadband connections are virtually omnipresent. However, the situation is different with the latency. The latency value (in milliseconds) indicates how much time passes during the transmission of data between multiple network hosts. A higher latency implies a lower data transfer rate.
This situation is the same in Across: a high latency impairs the speed with which Across can be used via crossWAN online, especially since Across uses the SQL Server very intensively for certain actions (several hundred requests per second). Therefore, if there is a long distance between the Across Client and the Across Server, the performance of crossWAN online is usually not satisfactory.
Furthermore, the satisfactory performance of crossWAN online depends on the type of action to be performed in Across. If an Across user merely wants to query the current project status during low-traffic periods, long latencies normally will not be a problem. In contrast, if the Across user wants to check in documents or assign tasks, every additional millisecond of latency will impair the speed of the operations performed over crossWAN online.
- Overview of common latencies (depending on the distance between the client and the server):
- LAN connections usually have latencies of less than 10 ms.
- Short-distance WAN connections usually have latencies from 10 to 50 ms.
- Long-distance (several hundred miles) WAN connections may have latencies from 50 to 250 ms, depending on the data traffic.
- WAN connections (via satellite) across national borders and continents may be subject to latencies of up to 2000 ms.
To use the crossWAN online mode, it must be activated with the option Enable crossWAN online users in the crossWAN/Grid section of the Server Administration settings of the Across Server.
Furthermore, make sure that the option Use default settings is enabled under crossWAN online in the settings of the crossTerm Server and the crossTank Server. In this way, the settings of the Across Server will be adopted automatically and do not need to be entered manually.
