The Mavis car rental company has a head office in Brisbane, Australia with branch offices in five cities in the state of Queensland. At head office there are 40 people: 5 top-level managers and executive officers. 5 mid-level managers who deal with procurement, car service etc. 5 customer service people who deal with significant events, usually ones that require legal procedures. 10 administrative staff who deal with the paperwork, procedures etc. 10 marketing staff, who develop, plan and execute marketing strategies. 3 HR staff who deal with employee data. 2 IT people who keep the existing IT infrastructure working. These 40 people occupy a single floor of a high-rise building, and space on this floor is extremely tight. Recently, the floor above has become vacant, and Mavis has chosen to purchase the floor above so that they can expand the head office. The plan is to move five people upstairs and also increase the staff at head office by 30 so that there are 70 people all up at head office.

Internet Bandwidth The current WAN connection to the Internet is a 5Mbps ADSL connection which is divided into a 4Mbps inbound link and a 1Mbps outbound link. Before 9am the ADSL connection is operating at about 10% capacity. As soon as employees arrive and begin reading their e-mails, the link capacity jumps to 100% saturated, and stays there all day until around 4pm. The traffic on the inbound ADSL link has these characteristics: 60% is web traffic including multimedia (images, video etc.). 20% is e-mail traffic. 10% is time-sensitive multimedia traffic, e.g. Skype. 5% is DNS traffic. 5% is other traffic such as SSH. Server Traffic All of the servers in Mavis currently have 100Mbps network cards and a connection to a 100Mbps port on a switch. Here are the baseline measurements: Server Average bandwidth Peak bandwidth Jane 10Mbps 50 Mbps Danny 20 Mbps 100 Mbps (limit of NIC) Opie 15 Mbps 30 Mbps Superstar 5 Mbps 100 Mbps (limit of NIC) Gotcha 5 Mbps 30 Mbps Sauron 20 Mbps 50 Mbps Each night, backups are done over the network from all the servers to Sauron which has an external tape drive. During each backup, the server's NIC operates at full bandwidth. At present, every server has its own internal disk drives, and there is no SAN on the network. Building Construction The building that Mavis occupies has exterior reinforced concrete walls which are 300mm thick. The floors are also made from reinforced concrete which is 300mm thick. The floors are suspended on eight 1000mm diameter concrete pillars which form part of the walls in the corridors. All interior walls on both floors are standard dry-wall construction except the seminar room and the boardroom which are built with 150mm reinforced concrete to ensure acoustic isolation.
