UDP Listener The UDP Listener can be used to open a UDP socket and forward the received packets to a parser. The UDP Listener can support multiple parsers if all of these parsers support protocol detection. If this is the case, each parser defined for the Listener will be asked if it can handle the incoming packet. The first parser that accepts the packet is then used to parse the packet and dispatch it to its Queue. If only a single parser is defined in the Listener, the packet is directly handed over for parsing.
