Business Requirements and Network Growth for XUMUC - Assignment Example

? SUB-NETTING AND IP ADDRESS SCHEME PROJECT (Number) Executive summary In the modern times, it is important for institution to have well documented schemes for their network designs. This is because the form assists them in learning about the details for their network depending on the business requirements for the network, growth estimates, applications running on the system, network storage needs, external network access requirements, remote network access requirements, and network support needs within the organization. This paper presents the network design documentation for XUMUC that has WAN links for its tow main regions (San Francisco and Denver). So far, no records that show the details of the network design that previously existed in San Francisco. Hence, in providing a well documented report about the IP addressing scheme as a result of the new routing table at the summarization points and at the San Francisco region, this report will explore how the VLAN structures shall be developed to isolate traffic broadcasts within the campus institution. In fact, it will take into consideration the fact that XUMUC has about four departments that include finance, sales, human resources, as well as research and development. Further, it will concentrate on the WAN transport issues that will ensure that the network design can eliminate high overheads when the company needs to expand in the near future. Introduction Recently, XUMUC institution that was only based in San Francisco merged with a Denver campus. The networking scheme was poorly documented for the original campus alone thus resulting in the presentation of poorly designed IP addressing schemes and an IP addressing table. In efforts to correct this error and ensure that the merger does not bring down the operations in the company, this paper presents details for their network design depending on various issues. It will consider the business requirements for the network, growth estimates, applications running on the system, network storage needs, external network access requirements, remote network access requirements, and network support needs of XUMUC organization as described in a scenario for the region. Networking Issues Present in XUMUC Depending on the background information provided for XUMUC campus, the organization has WAN links in place for the set up of any new locations in the Houston Region. The organization, which currently has two main campuses in San Francisco and Denver, was originally based in one campus (San Francisco). Further, the work of the consultant created very large routing tables at the summarization points and at the San Francisco Campus. In addition, the organization lacks VLAN structures that isolate broadcast traffic. In any case, the organization has about four main departments that should be considered and they include sales, finance, human resources, as well as research and development. Hence, the newly designed networking design documentation should also note that the WAN transport is able to accommodate the network traffic. Moreover, it should ensure that all addresses in the network are dynamically assigned to ensure that unlike the previous design, the high administration does not experience overhead when changes are needed within XUMUC. Business Requirements and Network Growth for XUMUC As previously stated, XUMUC has expanded and requires a network design that can assist the organization cater for network requirements of the campus in San Francisco and Denver. The Wan Link that is always available for the expansion to new locations in the Houston region is very useful as it is concerned about the network requirements at the higher level. However, the network needs to be set up in a way that it takes care of the expansions in the lower level as well. This is in the sense that the IP addressing scheme should integrate the two regions and leave room for addition of users within the network. This is because in XUMUC network growth is necessary especially considering the fact that the region currently has only four departments and very large routing tables at the summarization points. Therefore, the XUMUC network shall be divided based on region and departmental needs. This will allow the regions will larger population to take up a larger range of IP addresses but also leave room for expansion and the region with the smallest range to take up the smallest network. Case in point, considering the table below, San Francisco has the largest network requirements, as the region requires 1290 IP addresses while Houston region requires a lesser figure. Table 1: Number of IP addresses required Location Number of IP addresses required San Francisco 1290 Denver 504 Houston 350 Location Number of IP Addresses Required Address Block Assigned Subnet mask San Francisco 1290 172.16.0.0-172.16.7.255/21 255.248.0.0 Denver Region     Denver Campus 441  172.16.7.0-172.16.8.255/23 255.254.0.0 Remote Office 1 28  172.16.9.0-172.16.9.64/26 255.255.255.192 Remote Office 2 35  172.16.9.65-172.16.9.128/26 255.255.255.192 Houston Region     Houston Campus 329  172.16.9.129-172.16.10.128/23 255.255.254.0 Remote Office 3 21  172.16.10.128-172.16.10.160/27 255.255.224.0 In order to ensure that network storage needs, external network access requirements, remote network access requirements and network support needs are well taken care of, the network provided, 172.16.0.0/21 will need to be subnetted as per requirements. This shall be achieved through the borrowing of bits of bits within the network and determining of the network and host bits. VLAN structures will also be assigned to separate traffic and enhance development. Since the subnet will be based on regions, for scalability and proper utilization of the system, further subnets will be created within the subnets to cater for separate departmental needs. The network diagram below basically presents a physical figure of how the campus regions will be distributed. Fig 1: Network diagram for XUMUC Conclusion Like any other institution in the modern times, XUMUC is a company with great potential in growth. Therefore, in designing the networking system for the institution, it is critical that one considers the business requirements of the organization, possibility of growth and network supporting needs. Further, they should also consider the applications to be used within the network as well as the storage needs of the system. In this scenario, XUMUC has several departments that need to be integrated and all factors needs to be considered. The best option is subnetting the system separately by region and departmental basis. This is because this allows room for concentration on requirements of each region, and separation of network traffic depending on number of users and applications to be used and storage needs.
