Desain Topologi Jaringan Kabel Nirkabel PDII-LIPI dengan Cisco Three-Layered Hierarchical menggunakan NDLC

Information Technology (IT) has significant influence to a company. The robust network IT infrastructure should be installed earlier, supporting the information exchange through internet or intranet and it also should be easily accessible via wired or wireless network. PDII-LIPI (Pusat Dokumentasi dan Informasi Ilmiah - Lembaga Ilmu Pengetahuan Indonesia) Jakarta is an organization under LIPI which focuses on three processes for instance the documentation services, the information services and the development of documentation services. PDII-LIPI has already used IT to support those businesses so they must carefully choose the best network IT infrastructure. To achieve this objective, we propose a research which design wired and wireless network infrastructure at PDII ? LIPI. We use Network Development Life Cycle (NDLC) as a method for solving problem. This method is very useful in developing wired and wireless network infrastructure and it can monitor network performance. We expect the research can help PDII - LIPI in building and developing the infrastructure of wired and wireless networks to be more optimized in supporting existing business processes.
