High-Performance Applications
The best test of a network is the performance of the applications
that run on top of it. The concept of scalability goes beyond
the geographic reach of a network. It also addresses how well
a network can perform even as the usage of applications with
heavy bandwidth requirements increases. For example, Voice over
IP (VoIP) communications that rely on Wi-Fi connections draw a
significant amount of bandwidth. Rajant has found that traditional
VoIP architectures are particularly difficult and inefficient to manage
in remote network environments for a variety of reasons. Because
of this, and the fact that voice communications are often critical in
remote and mobile operations, Rajant developed Tactical Radio
over IP (TRoIP) to avoid shortcomings in standard VoIP protocols.
Common implementations of VoIP networks require a centralized
SIP (Session Initiation Protocol) registration server in order to map
a user’s VoIP domain contact, such as a telephone number or
