source: source/ariba/utility/addressing/mac_address.hpp@ 5870

Last change on this file since 5870 was 5284, checked in by mies, 15 years ago

+ added new transport modules and adapted ariba to them
+ exchange endpoint descriptors an link establishment
+ clean up of base communication
+ link establishment with in the presence of multiple endpoints
+ local discovery for ipv6, ipv4 and bluetooth mac addresses
