The IXrouter3’s VPN connection has a throughput speed of 8-10 Mbit/s. This speed is determined by the IXrouter’s hardware specifications and the type and level of cryptography (encryption and decryption of data packets). The recommended internet speed needs to be around 1.5 times higher, to cover the overhead of the VPN tunnel. The exact overhead is dependent on the exact circumstances, such as the size of the data packets you are sending through the VPN tunnel.
The speed of 3rd party Devices with an IXagent is determined by their respective OS and hardware specifications.
Every IXON Edge Device, when setting up a VPN connection, will get an IXON Cloud VPN server assigned. When assigning servers, care is taken to select a VPN server that is geographically close to the Edge device and that has enough resources available. As a rule of thumb, IXON calculates that every Edge device is allocated a 10 Mbit/s connection speed.
Any other Internet traffic, for example when a PLC communicates with another Cloud service through the IXrouter, will not go through the IXON VPN connection but rather over the local internet connection and will not be limited or throttled. This also holds true for the IXON Cloud Data Logging functionality, which is communicated via an MQTT connection, not the VPN connection. All Webaccess (viewing a PLC’s HTTP server or VNC server in the IXON Cloud portal) is also communicated over the VPN connection.
