An algorithm and software for finding proper packet size in an IPv6 network using double connection

Internet is near to one of the most important changes in its existence - the migration of core protocol IP to a new version IPv6. Along with other changes, one of the important results is that the IPv6 network will no longer cares for fragmentation. According recommendations the sending node is responsible to select proper size of packets to send. Present paper proposes one possible way for software applications to select the proper size of sending packets using two simultaneous connections between both sides.
