In this research paper, a new ISP Independent Architecture (IIA) for interconnectivity in hybrid network is
presented. This ISP independent solution provides flexibility to the users to deploy their required transition solution.
Our implementation uses 6in4/6to4 mechanism for tunneling with support of online tunnel broker by Hurricane
Electronics[16] and NAT64/DNS64 translation mechanism by Ecdysis[17]. A decision entity is deployed in the
network to provide intelligence regarding the packet traversing. For the implementation the pseudo code is also
presented along with the real time testbed setup.
This architecture is suitable in the environment where a network administrator wants to take benefits from the
features of new and upcoming tunneling and transitions mechanisms. The dependency of ISP's configured transition
mechanism is eliminated. Further, a network administrator can create multiple combinations of transition
mechanisms for different destinations to manage security and load balancing. In future, we will expand the
algorithm of the decision entity so that it can provide multiple translation and tunneling mechanisms. The algorithm
will adopt the network conditions as well.
