015.30.1 Korea Kilnam Chon R&D networking in Korea started in 1982 with two nodes supporting TCP/IP, a network known as the System Development Network (SDN). Since then, networking has grown to cover many R&D and academic organizations. Currently there are two overlapping efforts on the R&D networking. One is SDN, a network supported by membership fees and R&D projects. The other is the Research and Education Network Program sponsored by the Korean Government, which operates two networks: the Korea Research Environment Open Network (KREONet) and the Korea Research Educational Network (KREN). All of the three networks are interconnected via 56kbps lines. The three networks support around 55 academic and research organizations, most of which are connected by a leased line of either 56 kbps or 9600 bps. For international connectivity, SDN has a 56 kbps link to FIX-WEST via the University of Hawaii and KREONet has a 56 kbps link to the San Diego Supercomputer Center. TCP/IP is the dominant protocol and service in Korea. OSI is being developed extensively in Korea, but utilization is minimal. Bulletin boards for personal computers are growing rapidly. The Academic Networking Council (ANC) was established in July 1991 to coordinate R&D networking activities in Korea. The ANC has two classes of committees for managerial and technical coordination. The ANC has members from all three networks in Korea. The scope of ANC is two-fold. One is coordination of network operations such as naming, addressing, interconnection, and routing. The other is to represent Korea in international networking activities such as the CCIRN and the Internet Society. Networks in Korea share the same Internet domain naming scheme with user@[unit].organization.{ac,co,go,re}.kr where [unit] is optional.
