Some of the mechanisms discover the tunnel endpoint automatically by their own means. This paper describes several tunnel discovery mechanisms for IPv6 traversal beyond IPv4 legacy networks and suggests a new mechanism by which the DHCPv4 server can automatically provide configuration information about IPv6-in-IPv4 tunnel. Dual stack nodes attached to IPv4 network can communicate with other IPv6 networks by this mechanism beyond IPv4 networks without user intervention. Implementations have shown that the proposed mechanism can be a convenient and valuable tunnel discovery mechanism in some cases.

The integration of the RPAS as part of the network centric warfare would be a very important milestone to be achieved because of the huge amount of information and capabilities that all these aircrafts can incorporate to the global scheme. This integration is easier for hand held (short range) RPAS since their communications are typically based on digital transmission (like WiFi or WiMAX) but it may not be so obvious for bigger RPAS (long range like tactical or medium/high altitude systems) because their line of sight (LOS) communications are frequently based on analog transmissions. This implies an indirect integration to the network centric warfare by means of the ground control station (satellite communications, when available, may suffer a notorious delay for certain applications). This article presents a recent practical experience, including flight test campaigns, deploying an all-IP communication architecture into one of the most relevant Spanish tactical RPAS, the SIVA, used by both the Spanish Army and the Spanish Airforce during the last ten years. This deployment enables for a cost effective integration of this RPAS (and its natural successor, the MILANO, a medium altitude RPAS) into the network centric warfare by means of direct TCP/IP transmissions over a long range digital LOS channel combined with satellite communications for beyond LOS operations. The proposed design includes network-level security over the radio interfaces, automatic data-link selection, support of remote video terminals and access connectivity towards external IPv6 networks.
