 application.desc=Student assignments performed as part of NPS course Networked Graphics MV3500.  This course is an introduction to network communications in simulation applications. Topics include an introduction to the TCP/IP protocol stack; TCP/IP socket communications, including TCP, UDP, and multicast; and protocol design issues, with emphasis on Distributed Interactive Simulation (DIS) Protocol and High Level Architecture (HLA). Course emphasis is on creation and testing of network programming network code and web-browser applications.
