Local Area Network Design/ Network fundamental - Assignment Example

In addition, the current switch location points need to be changed. For effective network design, the needs to be switch located on each floor. The current router which is an ADSL modem being in use needs to be replaced. This is because the proposed merger will mean huge traffic from the various departments with regard to the Internet. Each departmental bandwidth requirement is not established as well as the QOS requirements for the different applications. An ADSL modem speeds go up to a maximum of 10mbps and which cannot support the new merger.

The speeds also vary quite considerably. They also have faster downloads as compared to uploads. Outdated Windows Server 2000 The current windows server 2000 server needs to be upgraded to a more advanced server. There is no organized way of handling the data as well as the documents. They are stored in unorganized way which can be a great issue when it comes to file management issues. Incompatible Systems Several departments in both companies are using different systems that are incompatible.

A good example is the accounts department which is using different payroll systems and stock control systems which are incompatible. After the merger this means that the firm needs to purchase compatible payroll and stock control system. . At the access layer is where the various wired and wireless LAN connectivity for the various ip devices i.e telephones, PDAs, surveillance cameras etc. A Number of considerations factored in while implelementing the above network include: Quality of service The various devices at the access layer should be able to identify, classify and queue traffic across the LAN to ensure there is optimal perfomance.

After careful assignment and management of the various applications, there is delivery of satisfactory perfomance across the entire LAN. Since each type of data flow will have different QOS requirements i.e the stock control and sales product system Security Measures: Strict security measures should be implemented to increase the security exposures which may have serious service impacts. By implementing the firewall at the router will prevent malicious attacks from outside the network. Similarily at the access layer integrated security features will be incorporated to guard against intruders as well as other external threats i.

e the DDoS attacks. An extra layer of security will be put at the access layer to ensure that the users are first authenticated and a virus check is performed on all the Pcs. This will ensure that there is end-to-end security policies which will determine who will get access what network resources as well as the QoS policies.To accommodate growth as well as new technologies, its advisable to use the modular chassis technology at the access layer. This technology will offers high density, high-speed ports with optional, cost-effective PoE capabilities.

By employing the EX4200 Ethernet Switches.this
