IPv6 transition problem from the application point of view
The IPv6 transition problem can be tackled from two different points of view:
- Network infrastructure transition:
Update network nodes to support IPv6.
- core network: intermediate routers which provide connectivity to the end nodes.
- end nodes: nodes used by end users to run applications.
- Application transition: Update applications to support IPv6. Networks APIs make visible IP version dependencies to the applications, for example, IP addresses.
Many transition mechanisms have been developed to provide coexistence between networks and applications. Nowadays we have a set of transition mechanisms which solve different communication problems and we have to select which one is the best for each particular scenario. The selection mainly depends on the applications and services required by the end users.
The aim of this document is to analyze the transition mechanisms which allow different kind of applications to exchange information.
When planning the IPv6 transition, an organization should following some steps:
- analyze the existing network.
- analyze the applications and services required for the users.
- propose possible network scenarios with IPv6 support.
- study if the applications and services work over the possible network scenarios.
