Features: To become a feasible platform in the telecommunications industry, softswitch must provide service providers with performance metrics that meet or exceed those of traditional time-division multiplexing. This ensures that both existing and new market service providers will adopt softswitch technology in their networks. These performance metrics include scalability, reliability, quality of service (QoS), feature functions, and signaling functions, among others. This book reveals how softswitch technology will impact existing service providers and their suppliers, which also helps to clarify successful cases and technical challenges based on softswitch solutions. It is suitable for professionals working on softswitch technology and can serve as a reference for related personnel. Softswitch technology is a platform capable of providing next-generation packet communication, including voice, broadband, and wireless networks. This book provides a comprehensive introduction to softswitch technology, from concepts and principles to standard protocols, in a step-by-step manner, with detailed comparisons between existing softswitch solutions and traditional Class 4 and Class 5 switches. The book primarily covers topics such as the architecture of softswitch, public switched telephone network (PSTN), VoIP, SIP, scalability of softswitch, effective analysis of softswitch versus Class 4 and Class 5 switches, QoS, Signaling System No. 7 (SS7), the economic benefits brought by softswitch, and the industrial transformation caused by softswitch.
