  • TECHNOLOGIES SUPPORTING VoIP1 In this chapter, we discuss and review various standard and emerging coding, packetization, and transmission technologies that are needed to support voice transmission using the IP technologies. Limitations of the current technologies and some possible extensions or modifications to support high-quality—that is, near-PSTN grade—real-time voice communications services using IP are then presented. VOICE SIGNAL PROCESSING For traditional telephony or voice communications services, the base-band signal between 0.3 and 3.

  • Internetworking: an overview of concepts, terminology, and technology underlying the TCP/IP Internet protocol suite and the architecture of an internet. Talking about computer networks often means talking about Unix. Of course, Unix is not the only operating system with network capabilities, nor will it remain a frontrunner forever, but it has been in the networking business for a long time, and will surely continue to be for some time to come.

  • Routing is simultaneously the most complicated function of a network and the most important. Most knowledgeable people agree that networking and routing technologies have been around about 25 years. The concept of routing actually dates back to the late 1950s, when computing was still an arcane science in its infancy. Precious few organizations had a single computer, much less multiple computers that needed to be linked together. Internetworking, the interconnection of multiple computers, was still more of a futuristic vision than a reality.

  • As the Internet continues to grow exponentially, the need for network engineers to build, maintain, and troubleshoot the growing number of component networks also has increased significantly. Because network troubleshooting is a practical skill that requires on-the-job experience, it has become critical that the learning curve necessary to gain expertise in internetworking technologies be reduced to quickly fill the void of skilled network engineers needed to support the fast-growing Internet.
