Net::Frame::Layer::UDP - User Datagram Protocol layer object
use Net::Frame::Layer::UDP qw(:consts); # Build a layer my $layer = Net::Frame::Layer::UDP->new( src => getRandomHighPort(), dst => 0, length => 0, checksum => 0, ); $layer->pack; print 'RAW: '.$layer->dump."\n"; # Read a raw layer my $layer = Net::Frame::Layer::UDP->new(raw = $raw); print $layer->print."\n"; print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n" if $layer->payload;
This modules implements the encoding and decoding of the UDP layer.
See also Net::Frame::Layer for other attributes and methods.
Source and destination ports.
The length in bytes of the datagram, including layer 7 payload (that is, layer 4 + layer 7).
Checksum of the datagram.
The following are inherited attributes. See Net::Frame::Layer for more information.
Object constructor. You can pass attributes that will overwrite default ones. See SYNOPSIS for default values.
Computes various lengths contained within this layer.
In order to compute checksums of TCP, you need to pass the protocol type (IPv4, IPv6), the source and destination IP addresses (IPv4 for IPv4, IPv6 for IPv6).
These two methods are basically used to increase the speed when using recv method from Net::Frame::Simple. Usually, you write them when you need to write match method.
This method is mostly used internally. You pass a Net::Frame::Layer::UDP layer as a parameter, and it returns true if this is a response corresponding for the request, or returns false if not.
The following are inherited methods. Some of them may be overridden in this layer, and some others may not be meaningful in this layer. See Net::Frame::Layer for more information.
No constants here.
