Basically , that means that the protocol manages the transmission of the data. With TCP , when you send a packet of data , its guaranteed to arrive.; #X text 34 202 By default , most networking objects in Pd use TCP: ; #X obj 54 223 netsend; #X obj 266 224 netclient; #X obj 359 224 netserver; #X text 178 295 UDP stands for User Datagram Protocol. It is a lightweight , simple protocol that is meant to be as quick and small as possible. The downside is that the data packets are not guaranteed to arrive. ; #X obj 35 180 pddp/pddplink http://en.wikipedia.org/wiki/Transmission_Control_Protocol ; #X obj 177 355 pddp/pddplink http://en.wikipedia.org/wiki/User_Datagram_Protocol ; #X obj 132 224 netreceive 32194; #X obj 265 386 netreceive 32194 1; #X obj 187 386 netsend 1; #X obj 407 386 sendOSC; #X obj 478 386 dumpOSC 32192; #X text 180 409 One advantage to UDP is that you do not need to maintain a connection to receive data. Whenever you open a UDP port , you will start receiving data.;
