The Management in the future would like to convert their existing wired network to wireless network so for the internet connection an ISP access point will be required. The wireless access point will make it possible for wireless devices to be added in the future. In a company security is very important so a firewall router will be attached to the access point to protect the company from outside attacks. A switch then will be attached to the firewall router. The servers which include database servers, web servers, e-mail servers, printer servers, file servers and application servers will be attached to the switch. For security purposes the servers and the switch will be kept in a separate room and this room will be kept locked so as to make it difficult for anyone to enter the server room and carry out any malicious activities. Several computers and printers will be attached to the firewall router so that there will be a network between the computers and they will be able to communicate with each other, share files and printers. The senior staff that will be working from home can get connected remotely to the office and access files on the server.

Implementing a remote working system within a company can have advantages and disadvantages for both employers and employees.

With a remote system an employee can work from everywhere whether he is at home, on the bus or at a client's house. One can even choose the hours to work without being limited to certain office hours. This gives employees the opportunity to either work in the morning or in the evening depending on their preferences. This in particular is an advantage to women employees as they can manage better their family responsibilities such as looking after young children or caring for a sick relative as well as carry on with their office work. This also leaves flexibility to an employee as one can deal with any unexpected situation that occurs through out the day. This in the end will lead to a happier employee and often will lead to an increase in productivity. It will also reduce travelling especially if the employee lives far away from the office, so it will reduce cost for the employee and save time. A remote system also give an employee instant access to files on the servers. Changes and additions for files can be done immediately and saved on the system. Other advantage for a remote system concerns the employer. If an employer has some of his employees working remotely than the employer can have a reduction in office space, he would need less furniture and equipment and in the end this can have a positive impact on the company's finance. Even if the remote working employees would need to attend at the head office they could make use of desk sharing. Employees will tend to remain within the company due to the benefits of being able to make use of flexible working hours and this can result in a potential reduction in the cost for recruiting and training new staff. Remote working also gives the opportunity to an employer to hold onto employees who move to live in another location. Employees who work remotely from home tend to take less sick leave as an employee who have a cold and would report sick if he had to go to the office, he might still be able to carry on with his work if he is working at home. Besides if an employee has an appointment at the dentist or at the doctor that employee can start working than go for his appointment and then go back to carry on with his work, something which the employee would not be able to do if he was in an office and he would have had to take some hours off from work.

Still a remote system has its disadvantages as well. Security could be one of the biggest disadvantages of a remote system as it could be risky to work outside the firewall. An employee that works away from the office may lack motivation which will result in the employer to loose trust and confidence in that employee. Employees could even feel lack of social interaction and lack of involvement in the sharing of decision making. This might lead an employee to start feeling isolated from his other colleagues. Apart from that an employee that works away from the office might find it a bit hard to feel part of a team as he does not get to see his colleagues frequently. Working remotely can reduce access to the company's information and can reduce an employee's involvement in team activities and training. There might be a lack of effective management and support structures which will leave an employee with the feeling of not being involved in the most important work of the company. Employees who work remotely from home should be self disciplined or else they will not succeed in the job. As Employees will not have any direct supervision and no colleagues to look over their shoulders it will be much easier to feel comfortable and this can sometimes affect employee productivity. If an employee is easily distracted or prone to become careless then working remotely can be difficult. On the other hand an employee might be tempted to work longer hours without taking regular breaks.

The company can enjoy from a lot of benefits when implementing the system mentioned in the scenario. On of the benefits is the cost reduction. As the company will have only part of the staff working in the office and the other part of the staff will be working from home, the company will need less office space and less furniture to accommodate all the staff. As the staff working from home will be connected through Virtual Private Networks (VPNs), the company needs to spend less money on leased lines and other network technologies. VPNs will provide the company with more flexibility in choosing the most cost-effective and high performance technology for the company. VPN can also reduce phone charges as it will replace remote servers and long distance network connection used to access the company intranet. VPN allow you to use the internet to enter into a virtual network through broadband connections.

Another benefit for the company includes increased security. VPN can provide information security by using encryption technology to send and receive data. VPNs make packets secure when sent across a public network. So the connection between the sender and receiver will be private, even though it makes use of links across public networks to carry information.

The company will also benefit from a better performance. With VPN higher capacity data service options can be used and so the bandwidth and efficiency of the network increases.

The company will be able to extend its services over other cities without the need to have offices build in those cities because the staff will be able to carry out the work from home. This will help the company to reach more customers.

It also improves scalability. For a company to upgrade its network and add new sites can be very expensive and time consuming, especially if legacy systems are still present. a VPN can be used to mix legacy systems with new technologies. VPN can also support different types of network technologies and it can be configured and re-configured if the network grows.
