Foil 22 Architecture of the WebDIS Prototype at the NPS - Networking (I)

From Distributed Simulation (DIS,HLA) HPCC and the Object Web Visit to ARL Aberdeen -- June 5-6 97. by Wojtek Furmanski *
DIS style networking is still cumbersome in current Java for the following reasons:
  • Peer-to-peer communication is not possible between Netscape applets since each applet can open socket connections only to the host that shipped that applet (Netscape security restriction)
  • Multicasting, already present in new Java release (JDK 1.1) is not yet supported by Netscape (which still runs JDK 1.0.2).
