VSCP level II is designed for TCP/IP and other high-end network transport mechanisms which are able to handle a lot more data (487 bytes instead of 8) then Level I devices. With the additional bandwidth that normally is available it is ideal to always have a full addresses in packets for this type of media. That is the full GUID (node address) is available in the frame.
A telnet type client server protocol is used, see [sec:VSCP-TCP/IP-Protocol] for a full description of the available commands. The VSCP daemon has this command set implemented in it's own tcp/ip interface, but a client only needs to implement a subset called the VSCP tcp/ip link protocol.
The TCP/IP driver of the VSCP daemon can be used to connect one VSCP daemon to other remote VSCP daemons or to lighter clients that export the VSCP tcp/ip link protocol. A client and the VSCP daemon can have a connection that is persistent or the VSCP daemon can connect to the client on regular intervals to fetch and send events. It is of course also possible for a client to connect to a VSCP daemon through it's TCP/IP interface instead.
A RFC 854 (telnet) based protocol is supported over TCP/IP. The protocol is implemented in an extended form in the VSCP Daemon and is described here. The protocol is very easy to implement in low resource clients and a driver is available that make connecting to a client a turn-key experience. Source for this implementation on Arduino and others is available in the firmware repository. For high security SSL is available as an option together with other security measures.
