HDSP (Hybrid Distributed
Simulation Protocol)
Abstract: Although
IP multicast can be used to support message transmission among players in large
network games running on Intranets, it is mostly not available on the Internet.
Alternatively, researches have in recent years proposed the use of Application
Layer Multicasting techniques (ALM), either using proxies or purely depending
on end systems, to allow scalable message passing among peers in a group of
users on the Internet. We propose a hybrid application-layer multicast
framework that uses both proxies and end-systems to provide scalable and
timely-reliable communication among players of a game networked over the
Internet. Our field trials using a shoot ‘em up game show that the proposed framework performs
satisfactorily over the Internet.
