Conclusion
This chapter has described the major components of the PSTN. By categorizing the diverse components of the PSTN into three simple elements, access, switching, and transport, a framework is provided for understanding how comparable elements of a softswitch solution replace those of the PSTN, enabling bottlenecks to be bypassed in the PSTN when delivering voice services to subscribers. Many concepts deployed in the PSTN have been translated into softswitched networks, including signaling, voice codecs, and transport. When this technology can be duplicated by startup technology providers and implemented by competitive service providers, competition to the local loop becomes possible.

Softswitch Architecture or It s the Architecture, Stupid!
3
A softswitched network, like the Public Switched Telephone Network (PSTN), can be described in terms of its functions: access, switching, and transport. Where the two types of networks are decidedly different is in their architectures. The PSTN is a centralized architecture while a softswitch architecture offers a distributed architecture. This chapter will describe the architecture for softswitch solutions, detailing the major components that comprise this new and flexible architecture. Although many of the rules of construction change drastically with the shift to a packet-switched client-server architecture, the basic functions remain the same. Much of the current architecture for softswitch networks reflects attempts to protect an investment in the legacy aspects of a network, and softswitch components bridge the legacy technology with nextgeneration technologies. As economic models dictate new strategies, legacy equipment will be replaced by softswitch architectures. New market entrants will have an advantage by deploying softswitch solutions from the start. Incumbents will be disrupted by an architecture that is cheaper, simpler, smaller, and more convenient to use.
Softswitch and Distributed Architecture: A Stupid Network
Figure 3-1 illustrates the distributed architecture that is generally agreed upon as the model for softswitch networks. This model decouples the underlying packet-switching hardware from the call control, service logic, and new service creation. This distribution enables flexibility in hardware choices as well as the innovation of new services without requiring changes in the switching fabric or structure. This model also opens up the opportunities for third-party developers. The bottom layer is considered to be the bearer or transport plane, which physically transports both voice and data traffic. This plane consists of the media gateways in the softswitch solution.1 What makes this possible is the client-server architecture of softswitch, as opposed to the mainframe architecture of the Class 4 and 5 switches (see Figure 3-2). One advantage is that it enables a service provider to start
