StrataCom Intelligent Network Server
This chapter provides information on the StrataCom Intelligent Network Server (INS) hardware platform. The information is organized into the following sections:

The StrataCom Intelligent Network Server is a standard, high-performance UNIX hardware platform running networking software modules to support a number of network functions, including dial-up Frame Relay, switched virtual circuits, and PBX dynamic network switching. This choice of hardware as a foundation for INS functionality provides favorable price/performance, as well as a highly flexible base for rapid development of new features. Whether the features are intensive in terms of processing, memory, or database functions, the INS platform has the flexibility to address them.
The Intelligent Network Server (INS) provides intelligent call processing for ATM WAN's. Running on a SparcStation, the INS supports three key applications:
The INS provides you with the instantaneous, any-to-any connectivity required by applications such as LAN internetworking, client/server and client/client computing, shared workspaces, remote access, and multimedia communications.
The INS is a scalable, flexible platform that provides advanced data and voice networking services on wide-area networks. The INS provides intelligent call processing for ATM WANs and supports capabilities that enable network operators to customize and enhance their service offerings. INS enables the construction of virtual enterprise networks. Virtual enterprise networks address the need for extending high-speed access to many different users in diverse geographies while facilitating the dynamic allocation of circuits and bandwidth capacity.
Key to the INS's functionality is the sophisticated interaction between the platform's call processing and signaling software and the network database. This interaction creates advanced switching capabilities.
The INS design is based on approved standards and implementation agreements from the ITU-TSS (CCITT), ANSI, ETSI, ECMA, the Frame Relay Forum, and the ATM Forum.
The Intelligent Network Server includes the following features:
A fundamental characteristic of the INS architecture is the division of functionality between switches and intelligent network servers. The switches handle the actual switching of the traffic. They manage existing connections by performing the routing, rerouting, bandwidth optimization and resource allocation. The servers handle new call processing requests, including functions such as evaluation of potentially complex criteria for connection initiation, handling of multiple addressing schemes, and enforcement of security. The servers also maintain an image of the appropriate network dialing plans that is used to determine the destination of all ISDN and SVC connections initiated toward the network.
This division of functionality offers optimum cost, performance, and feature availability, especially in light of the growing complexity of high-speed networks and the rapidly evolving standards and applications associated with them.
The Intelligent Network Server is based on an extremely reliable hardware and software platform. A1:1 redundancy is available for the INS, and multiple INSs can be deployed within the network to support a load-sharing arrangement. The implementation of specific features, such as ISDN access to Frame Relay networks, provides further robustness by allowing any access port to serve any user, thus enhancing the overall reliability of the entire wide area network.
INS performance is completely scalable, through the deployment of more powerful hardware platforms or the deployment of additional servers within the network. Capacity can be added cost effectively as user demand requires.
INS supports industry standard signaling protocols for ISDN, Frame Relay, and ATM. The flexibility of the INS platform also enables StrataCom to respond rapidly to changes in networking standards. Key standards supported include the following:
