....parameter space in the simulation. Typically, the definition of the multicast groups of receivers is static, based on a priori knowledge of communication patterns between the processes in the simulation (Smith, Russo Schuette 1995, Mastaglio Callahan 1995, Macedonia, Zyda, Pratt Barham 1995, Calvin, Chiang Van Hook 1995, Steinman Weiland 1994) For example, the High Level Architecture (HLA) utilises the routing space construct, a multi dimensional coordinate system whereby simulation federates express their interest in receiving data (subscription regions) or declare their responsibility for publishing data ....

....static, based on a priori knowledge of communication patterns between the processes in the simulation. Indeed, most real time large scale distributed simulators such as ModSAF (Smith, Russo Schuette 1995) CCTT (Mastaglio Callahan 1995) NPSNET (Macedonia, Zyda, Pratt Barham 1995) STOW ED 1 (Calvin, Chiang Van Hook 1995) and HLA utilise static interest management schemes. Static, grid based filtering has the disadvantage that in order to filter out all irrelevant data, it requires a small cell size, which in turn implies a large number of multicast groups. However multicast groups in a network are a limited ....

....in Section V. Researchers in the area of distributed simulation have been concerned with the problem of interest management for a number of years [12] Several researchers have proposed to include a specific network agent that manages the mapping of interest groups to multicast groups [13] [14]. Typically, interest grouping is done on the basis of (x,y) grid coordinates [15] 16] a natural interest clustering for the application area of distributed interactive simulation. A.3 Reliable Multicast Reliable multicast protocols ensure delivery of all data transmitted to a set of ....

....as both local and remote entities move across cells. Since the Application Gateway supports an instantiated IM coupled with a DOR which changes, this is the first system surveyed with an instantiated IM with a dynamic DOR. 4. 6 STOW ED 1 Synthetic Theater of War Engineering Demo 1 (STOW ED 1) [21, 5, 4], October 1995, was the first in a series of engineering demonstrations with increasing levels of functionality planned for the next STOW system, scheduled to complete in 1997. STOW 97 is designed to improve joint services training. This system is planned to eventually support 10,000 entities at ....

....that permit construction of simulations that can operate successfully in exercises of any scale subject only to constraints on local simulated object density. Many of the ACTs developed under the RITN program and employed during ED 1A have been described at previous Workshops, see references [1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 16, 17], for example. The content of this paper represents a subset of the analysis of the ED 1A data that has been carried out by the RITN development team. The remainder of this paper goes on to first briefly describe the system that was implemented for the ED 1A test, followed by an overview of the ....

Our analysis will compare these predictions to the values determined from the STOW E data logs. 3. 0 SUBSCRIPTION IMPLEMENTATION FOR STOW ED 1 The presentation will also feature a description of the subscription system [1] built to support the STOW ED 1 exercise. The subscription implementation for ED 1 contains two main parts, a Subscription Agent (SA) and a Subscription Principal (SP) The SP is the portion of subscription which exists in the simulation application. An API exists as an interface between the ....
