Communication - Transports
Transports
In addition to the legacy ITP protocol, PROLIN Power Server provides a concept called transports.
You can think of a transport as a communication channel with its own characteristics, which allows PROLIN Smart Client installations to communicate with a running PROLIN Power Server instance.
Depending on your type of network, the protocol, and the compression used, these transports may improve the overall network performance between client and server.
Available Transports
| Transport | Protocol | Compression | Default Port |
|---|---|---|---|
| net.tcp | net.tcp | Lzf4 | 5100 |
| net.tcp.lite | net.tcp | Deflate/6 | 5101 |
| http.lite | http | Deflate/6 | 5180 |
| itp | itp | GZip | 30999 |
Which transport works best in your environment mainly depends on your network type:
- LAN →
net.tcptypically works best
- WAN →
http.liteornet.tcp.liteare better suited
- Under very specific circumstances, the legacy itp transport might still be the preferred choice
By default, all transports are enabled, and each has its own default port as shown in the table above.
NOTE
The transports that make use of either the net.tcp or http protocol depend on the Networking Extensions (NetX) module.
These transports are not available if the module is not started.
