al-time communication software, which facilitates real-time communication between restaurant customer service staff and a number of consumers in a timely manner and record customer orders and consulting information; customer database, which records the food, frequency, and amount that customers consume in the restaurant to facilitate the restaurant to carry out targeted marketing activities; route query software, which facilitates consumers’ inquiries of the most convenient route to the restaurant.
2.3 Plan
2.3.1 Overall planning and design
Based on the full discussion with the management of the restaurant, according to the above network scheme, a series of design will be carried out, such as planning IP address, determining all kinds of equipment in the whole network, determining IP address of router / switch / server / PC; developing security policy, formulating routing control
strategy and so on. Network planners will be responsible for this step and it will cost 16 staff hours.
2.3.2 Procurement
The routers, switches, network cables, servers, and firewall software used in this project will be purchased from D-Link company. This step will be completed by the network technicians and procurement personnel of the restaurant and it will take 24 staff hours.
2.3.3 Installation
In corresponding locations, the hub in programs can be installed, through physical connection to link various network equipments to achieve the physical connectivity of equipments. According to the established design to configure each network equipment: routers, switches, firewalls, network management software to prepare for the final realization of network design. Network installers will spend 24 staff hours for this step.
2.3.4 Deployment
As there is not relatively complex and large amount of data that the restaurant needs to deal with, the restaurant's system deployment should use a centralized structure. The so-called centralized structure refers to that a central computer will compose the central node, the data is stored in the central node, and f all business units of the entire system are deployed in the central node, all the functions of the system are processed centrally in the central node. Each terminal or client is only responsible for data entry and output, data storage and control processing are entirely completed by the host. The centralized system is characterized by the simple structure of deployment, easy maintenance and low costs, centralized deployment is in line with the real needs of the restaurant. This step will be completed by the network technician by spending 16 staff hours.
2.3.5 Integration testing
After completing the testing / installation / configuration of the network, a series of tests on the network will be carried out. Testing network connectivity to ensure that the network can pass, according to the developed network security policy to test network security, including whether the configuration of each network device is correct, whether they meet the demand; whether the network management software can reflect the network status, network technician will be responsible for this step and it will last 16 staff hours.
2.3.6 On-site training
After completing the installation / configuration / testing of the network, it should provide on-site training to network user administrator, introduce the roles and configuration of each netwo
