IS3120 Final Project: Network Design Proposal
NCIF is an industry leading research and development firm consisting of eight (8) regional offices in seven (7) countries, including the United States, Germany, Africa, India, Australia, Brazil, and China, with eleven(11) district or branch offices, consisting of 225,000 employs worldwide. NCIF resides in Hopkinton, MA (USA).
NCIF’s network has been designed in adherence with the latest IEEE 802 series of standards. In keeping with these standards NCIF has installed and configured a Local Area Network (LAN) using the ...view middle of the document...
In order to anticipate future growth and keep network traffic to a minimum, NCIF has configured, one Class B network sub classed into several smaller networks based on department/job function at each regional and remote site – implementing the dynamic host configuration protocol (DHCP) in order to assign each terminal a unique IP Address – separating each department into Zones or Segments designed to mitigate risk management and provide increased security.
This is accomplished by assigning like-resources a specific IP range and VLAN. Each VLAN ends with a router/firewall interface designed to manage basic network access decisions in accordance with local Security Policies and Practices. This type of zoning enables NCIF to assign specific access rules and restrictions to each user or terminal based on their assigned zone or network segment.
In order to maintain proper IP Addressing, provide broadcast filtering, security, address summarization, and traffic flow management each network construct has been connected via a combination of routers and switches configured for multi-layer networking using Virtual LAN (VLAN) technology, providing a one-to-one relationship between VLANs and IP subnets, which has been broken down in the proceeding tables/documentation.
