Looking for RS-485 (half duplex) based "Network" library

I want to build Microchip PIC based devices, communicating over longer distances with each other.

Sadly Ethernet is no option with PIC32, as Microchip kas nothing similar to the PIC18F67J60 in 32 Bit. All Pic32 only have the MII, but no PHY inside the MCU, this rises costs and footprint drastically.

So my plan is to use RS-485 in half duplex mode (2-wires), this is slower, but available then on all platforms (8-Bit, 32-Bit, ...).

What I am looking for is a library, running interrupt driven background communication similar to a LAN. So it has to have collision detection (if two PICs try to send at same time), as well as a send and receive buffer, as much as possible should run in the background.

Is something like this available?

I want to deplou UDP client along with http demo pic32.

I want to broadcast messages using UDP over LAN using Net_Ethernet_sendUDP() function.
Can anyone send me udp client demo or examples as library help doesn't documented well ?

about CAN Bus frame structure

unsigned short CANWrite (long id, char *data, char datalen, char CAN_TX_MSG_FLAGS);

the above mentioned function used in CAN Bus protocol.
but the standard CAN bus protocol is
Id,control,data,CRC,Endof frame.

so how does this function works when data length or data bits interchange
