Center Mission and Rationale
The explosive growth of the internet and the dramatic globalization that impacts every facet of life is fueled by the rapid acceleration of advanced computing and communication systems. At the Center for Advanced Computing and Communication (CACC), multi-disciplinary teams collaborate with researchers from industry, government agencies, and other universities to develop and implement these leading-edge systems. CACC initiatives include complex, fault-tolerant, and distributed computing systems as well as underlying technologies such as photonics, pervasive computing, and wired and wireless elements.

CACC's primary goal is to create concepts, methods, and tools for use in the analysis, design, and implementation of advanced computer and communication systems. To achieve this, our researchers collaborate with industry and government agency sponsors to analyze, design, and implement these increasingly complex systems in areas where the CACC resources complement or supplement the resources and expertise available within a member organization.

Our graduate students are one of our most important products. Many collaborate with industry and faculty researchers on sponsored projects, while others do co-ops and internships. Because of the skills and knowledge they develop working on real-world research, our graduates are in high demand. Many are employed by member organizations upon graduation.

Our programs are enhanced by affiliated laboratories that serve researchers, students, and industry and government clients. The Multimedia and Networking Laboratories support research and education in multimedia technology, high-speed communications, network-based educational technology, and knowledge-based learning environments. The Networking Laboratory is used by students in the NCSU Master of Science in Computer Networking program and it also serves as a practice site for Cisco Certified Internet Expert (CCIE) certification. Industry vendors use the Centennial Networking Lab for interoperability exercises and contracted evaluation and testing. This suite of facilities at NCSU, along with additional labs at Duke, serves as a high-speed testbed for many networking research projects. The CACC Imaging, Microsystems, and Electronic Systems Laboratories support faculty and student researchers in their areas of specialty. The Ecommerce initiative focuses on studies of computing and communications infrastructure and applications needed for success in Ecommerce and Ebusiness ventures. These laboratory resources provide the unique capability to develop an idea from conception to simulation to fabrication to testing.
