The DREN is the United States Department of Defense’s research and engineering computer network. The DREN is a high-speed, high-capacity, low-latency nationwide computer network for computational scientific research, engineering, and testing in support of the DoD's Science and Technology and Test and Evaluation communities.

| - The Defense Research and Engineering Network (DREN) — a high-speed national computer network for computational research, engineering, and testing — is a significant program within the HPCMP. The DREN is the United States Department of Defense’s research and engineering computer network. The DREN is a high-speed, high-capacity, low-latency nationwide computer network for computational scientific research, engineering, and testing in support of the DoD's Science and Technology and Test and Evaluation communities. The DREN connects scientists and engineers at the HPCMP's geographically dispersed high performance computing (HPC) user sites, including the five DoD Supercomputing Resource Centers — hosted by the Army Research Laboratory, Engineer Research and Development Center, Naval Meteorology and Oceanography Command, and the Air Force Research Laboratory — along with more than 150 user sites at other government laboratories, test centers, universities, and industrial locations. The DREN wide area networking (WAN) capability is provided under a commercial contract, currently awarded to CenturyLink. It has been awarded in the past to AT&T, MCI/WorldCom, and Verizon. The DREN WAN service provider has built DREN as a virtual private network based on its commercial infrastructure. It currently supports IPv4 and IPv6 at bandwidths from DS-3 (45 Mbit/s) at some user sites up to Optical Carrier-48c (2.488 Gbit/s) and 10-gigabit Ethernet connections at selected high performance computing centers. In 2003, DREN was designated the Department of Defense's first IPv6 network by the Assistant Secretary of Defense for Networks & Information Integration.
- The High Performance Computing Modernization Program (HPCMP) was initiated in 1992 by the Department of Defense (DoD) in response to congressional direction to modernize the DoD laboratories' high-performance computing (HPC) capabilities. The HPCMP was assembled out of a collection of small high-performance computing departments, each with a rich history of supercomputing experience that had independently evolved within the Army, Air Force, and Navy laboratories and test centers. The HPCMP supports DoD objectives through research, development, test, and evaluation (RDT&E). Scientists and engineers that focus on science and technology (S&T) to solve complex defense challenges benefit from HPC innovation.
