Differences from IEEE 802.21

No compatibility at all. This software was inspired by the standard and even has some of it's features, but it was meant to be used in a specific situation on the college I attend.

Assumptions

• Hardware doesn't change. In case of hardware change (e.g. an NIC disapears), the behavior is undefined. NOTE: point-to-point 3g interfaces don't count, it's assumed they're not permanent.

• The best link is always the one of the most reliable technology (e.g. wifi > 3g). If technology is the same, the best link is either the one with best signal strength or the first.

• The 3g Base Station do not support MIH-like services, at least not the one implemented by this application. That means that no peer discovery is done when you connect to a 3g network.

• There's no other application managing NICs. The program tries his best to keep NIC information updated, but if an external program changes anything the behavior is undefined.
