This paper presents an executable semantics of OO models. We made it possible to conduct both simulation and theorem proving on the semantics by implementing its underlying heap me...
This paper describes two systems to recover the Internet connectivity impaired by private networks and firewalls. These devices cause asymmetry in the Internet, making peer-to-pee...
Firewalls/NATs have brought significant connectivity problems along with their benefits, causing many applications to break or become inefficient. Due to its bi-directional commun...
Applications that use CORBA as communication layer often have some restrictions for multi-domain deployment. This is particularly true when they have to face firewall/NAT traversa...
