Network stack virtualization
Abstract
Embodiments contemplate network stack virtualization which may be virtualization of a portion of the communication stack, such as the protocol stack, in some embodiments, multiple functionally of independent copies of the protocol stack may be simultaneously running on the terminal and/or serving the needs of different applications. This may allow independent operation from the application point of view, including connectivity to different networks with different identities. Embodiments contemplate that any number of such virtual network stacks can be instantiated, perhaps in some embodiments depending on the characteristics of an active application. Embodiments also contemplate the presentation of multiple allocated internet protocol (IP) addresses that may have sufficient information to enable an intelligent source IP address selection on the WTRU. The WTRU may be able to select an optimum IP address, perhaps in some embodiments depending on which application may be started.
