3. If possible, connecting to a single service provider will usually provide increased service levels because all of the network transit points are under the control of a single provider. Some providers will even offer service guarantees for customer traffic as long as it does not leave their network, which can be very important for customers deploying services that are sensitive to delay, such as Voice over IP (VoIP). 4 shows how a company may have its offices split into multiple regions around a country.

Although the model was still in its infancy, the ARPANET designers were beginning to encounter various types of networks that needed to connect to their systems, and they faced a variety of challenges. The challenges faced by Kahn and Cerf would sow the intellectual seeds for the development of a protocol that could provide intercommunication across a wide variety of systems and physical infrastructures. These seeds would later bear fruit with the development of TCP/IP. ARPANET Challenges and the Origin of TCP/IP One of the biggest initial challenges to the ARPANET was to guarantee a high degree of reliability across a variety of communication media.

Layer 3—TCP C. Layer 4—UDP D. Layer 2—PPP You will find the answers to each of these questions in Appendix A. com to take all the assessment tests and review the answers. 1: Before the Internet In the earliest days of computing circa the late 1960s, the majority of companies purchased only a single large system to handle all of their data processing needs. The systems were proprietary and closed, using hardware and software architectures that were compatible only with the same manufacturers’s equipment.
