The IP is responsible for the end-to-end delivery of datagrams over an Internet.
It also provides host and network addressing and the means for fragmenting datagrams into manageable packets.
IP is a routable protocol and much of its complexity is due to its ability to route packets directly within a local network or indirectly through routers.
Routers are not ideal for a control network since they reduce determinism and increase data latency.
Still to accept TCP as a transport layer for an Ethernet control network requires acceptance of IP as well.
By understanding the limitations of IP, a control network can still be designed using the TCP/IP family of protocols.
This is especially true if the control network is restricted to that of a private or local network.
