Upon arrival at the destination, the original internetworking message is reassembled in the correct order, based on the imprinted packet sequence number. Thus a virtual connection is established with the end-station through a Transport Layer protocol; though, typically, intermediate network nodes only render connectionless Internet Layer service for packet-switched messages.
IPSec network security capabilities
Internetwork security is integrated into the design of the IPv6 architecture, and the IPv6 ITEF specification mandates support for IPSec as a fundamental interoperability requirement.
