The Internet Protocol (IP) lies at the heart of the transformation affecting almost every aspect of telecommunication network operation. This technology is designed to route data packets between data networks in a resilient way. Initially, it became globally significant because of its role as the routing technology in the Internet. However, IP, and many other closely related protocols and technologies, are today being incorporated into structured fixed and mobile telecommunication networks.

The courses in this category cover all such technologies and describe where, how and why they are employed in the telecoms world. Although IP is a specific technology, it has come to be adopted as a generic term describing all the technologies used in managing the flow and security of information carried over packet data networks. Technologies and techniques such as the Multi-Protocol Label Switching (MPLS), IP Multimedia Subsystem (IMS), Session Initiation Protocol (SIP), IP security protocols, IP routing and addressing protocols and softswitching architectures are covered by the courses in this category. All are key enablers for operators to build cost-efficient IP-based networks that can provide a full range of high-quality telecommunication services.

This category also contains technologies that are used as to provide specific services such as Voice over IP (VoIP) and IPTV.
