The [Tcl] [core] has supported [TCP] sockets via `[socket]` since version 7 or so, but [UDP] must be supplied by an [extension]. ** See Also ** [UDP in the Tcl core]: ** UDP Protocols ** [TFTP%|%Trivial FTP]: ** Tcl UDP Extensions ** The following extensions provide UDP support: [TclUDP]: The normal package for standard UDP client/server programs. It is quite simple to use. [Tcl-dp]: An extensive TCP/IP package which also supports UDP [Scotty]: An SNMP package with its own UDP implementation [pktsrc]: Access to raw IP Datagram and thus to UDP [ceptcl]: Communications EndPoints for Tcl [Packet]: A few Tcl routines for manipulating network packets [UDP extension]: a small and clean critcl-based extension written in 2011 by [CMcC] [Duft]: Datagrams and Udp For Tcl ** UDP enabled packages ** [PT]: The [dns] package in [tcllib] is capable of using udp if available. So are the [time] and [ntp] packages. <> Category Glossary | Category Internet | Category Networking
