NAME

       Net::Frame::Layer::IPv6::Fragment - Internet Protocol v6 Fragment Extension Header layer
       object

SYNOPSIS

          use Net::Frame::Simple;
          use Net::Frame::Layer::IPv6::Fragment;

          my $icmp = Net::Frame::Layer::IPv6::Fragment->new(
             nextHeader     => NF_IPv6_PROTOCOL_TCP,
             reserved       => 0,
             fragmentOffset => 0,
             res            => 0,
             mFlag          => 0,
             identification => 0
          );

          #
          # Read a raw layer
          #

          my $layer = Net::Frame::Layer::IPv6::Fragment->new(raw => $raw);

          print $layer->print."\n";

DESCRIPTION

       This modules implements the encoding and decoding of the IPv6 Fragment Extension Header
       layer.

       RFC: ftp://ftp.rfc-editor.org/in-notes/rfc2460.txt

       See also Net::Frame::Layer for other attributes and methods.

ATTRIBUTES

       nextHeader
           Protocol number of the next header after the Fragment header.

       reserved
           Not used; set to zeroes.

       fragmentOffset
           Specifies the offset, or position, in the overall message where the data in this
           fragment goes. It is specified in units of 8 bytes (64 bits) and used in a manner very
           similar to the field of the same name in the IPv4 header.

       res Not used; set to zeroes.

       mFlag
           Same as the flag of the same name in the IPv4 header - when set to 0, indicates the
           last fragment in a message; when set to 1, indicates that more fragments are yet to
           come in the fragmented message.

       identification
           Same as the field of the same name in the IPv4 header, but expanded to 32 bits. It
           contains a specific value that is common to each of the fragments belonging to a
           particular message, to ensure that pieces from different fragmented messages are not
           mixed together.

       The following are inherited attributes. See Net::Frame::Layer for more information.

       raw
       payload
       nextLayer

METHODS

       new
       new (hash)
           Object constructor. You can pass attributes that will overwrite default ones. See
           SYNOPSIS for default values.

       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.

       computeLengths
       computeChecksums
       pack
       unpack
       encapsulate
       getLength
       getPayloadLength
       print
