UDPIPEncap

UDPIPEncap Element Documentation

NAME

UDPIPEncap — Click element; encapsulates packets in static UDP/IP headers

SYNOPSIS

UDPIPEncap(SRC, SPORT, DST, DPORT [, CHECKSUM])

Ports: 1 input, 1 output
Processing: agnostic

DESCRIPTION

Encapsulates each incoming packet in a UDP/IP packet with source address SRC, source port SPORT, destination address DST, and destination port DPORT. The UDP checksum is calculated if CHECKSUM? is true; it is true by default.

As a special case, if DST is "DST_ANNO", then the destination address is set to the incoming packet's destination address annotation.

The UDPIPEncap element adds both a UDP header and an IP header.

The Strip element can be used by the receiver to get rid of the encapsulation header.

EXAMPLES

  UDPIPEncap(1.0.0.1, 1234, 2.0.0.2, 1234)
