Ericsson's family of carrier-class technologies
Göran Ahlforn, Erik Örnulf · 2001
The ever-growing demand for rapid introduction of novel services and the pursuit of the most effective transport technology have led the telecommunications industry to shift to a horizontally layered architecture. An underlying trend—the convergence of telephony, data communication and media technologies—is further accelerating the development of new products and services for introduction into the network. In response to this trend, Ericsson—besides evolving AXE—has introduced two carrier-class technologies: TSP for servers, and CPP for gateways (Figure 1). Each of these meets the fundamental requirements for high availability and has been optimized for its role in the network. In the layered network architecture, telephony services are being aligned with what is called the server-gateway split (applications and control functionality are separated from connectivity and transport). In accordance with this architecture, services are introduced in the applications and control layers. A family of servers is being introduced in operator networks and will be subjected to the same requirements for carrierclass performance as all other network equipment. The servers occupy a central position in the network, storing and processing large amounts of data. The access-network products are based on a technology which • meets stringent requirements for high performance; and • is optimized for cost-effective ATM and IP data transport.
