Network Design - Essay ExampleIt will also have T3 of 10 Mb/s for connection to the internet including remote connection to the engineering department by means of the ATM. The design will use IPSec Virtual Private Network to create connections mingled with different sites and the subsidiaries of SHFL in Vienna. The available options for accounting executives include IP Sec Virtual Private Network Secure Socket Layer The cost of all equipment essential is about US $500000. Core Switch This will act as the access point to the internet or to the WAN. It will link through servers, and will be able to connect switches to collect the workstations of the net profit and other items. It is the center to the LAN networks in SHFL, through which most of the A great deal of SHFLs business operations will be conducted over the local area network, such as document processing, file sharing, e-mail, customer relations management, and much more. Therefore, SHFLs core switch will need to be fast an d efficient in order to support SHFLs operations. The recommended Cisco catalyst is 6506-E switch, priced at US $ 22967.99. We preferred to choose this switch because of its wide bandwidths and the size of its port, being 20 GB E ports. ... One of the Cisco Catalysts will be put in the IDF, first floor of the building (Raza and Turner, 2002). The second one will be put at the MDF office, second floor. This design is expected to improve the consistency of network connectivity and eradicate network downtime and failures. The core switch controls the problem of power outages. Loops are avoided by connecting and disconnection at the switches. Connectivity to Core Switch The recommendation for connection at the core switches is done through the router and other network switches. The mode of connection is through quality optic cables, to strengthen the network. Fiber Optic is able to disseminate data faster and with minimal error rates. The Fiber optic channels will be able to support multiple applications for SHFL workers. The cables are safe from the burden by electromagnetic signals, because its signals pass through a glass cable, which is a non-magnetic material. The electromagnetic interferences do not create noise (Earnhardt, 2006). The transmission through fiber optics goes through very long distances. The budget for expanding network will be about US$10,131.99. Connectivity between Workstations We will have switches to link to the PCs in the SHFLs LAN. This is because switches as opposed to hubs, allow the LANS for the SHFL to operate effectively by overcoming network congestion. We recommend a network design with 9 switches, to boost the network connectivity speed. preferably of using, fewer switches congested with the traffic. Each of the switches costs US $ 1,588.99. Each LAN in SHFL network will have at least 2 switches through which all PCs and Network devices are connected. The connection can use either RJ cables or Fiber Optics. Internet Connecti vity We
