Ogban Department of Computer Science, University of Calabar, Calabar, Nigeria Abstract This work tends to propose a billing system that is measured by the quality of bits/bytes transfer. In order to determine the amount of network resources to be reserved, traffic and performance descriptors must be defined. Allocated resources are used only when customers send or receive traffic, whereas when customers are inactive, resources may remain unused. Network administrators clearly prefer to charge users in proportion to the reserved resources, that is to say in proportion to the potential use of the service. In packet-wise billing system, subscribers are bill based on the actual amount of data transferred as in terms of byte. This research was carried out at unical e-library because of their facility, the researcher designed a server which serves as the billing system, in the server which is ubuntu driven, the researcher install the radius server, PHP Admin and mysql. The reason being that the radius server will do the authentication, accounting and access control, then the researcher use the packet sniffer to retrieve packet from the network using mikrotik router to connect the server and the client computer. It was discovered that when a user tries to connect to the server, it will be requested to enter a username and password that will give him/her access to the server. With this a capture will display showing that the user was successfully logged in with it bandwidth detail on it instead of time. So with this, a user can freely enjoy the service of the internet Keywords: reserved packets,, bandwidth, packet-wise billing system, processor clock timer, weighted fair queuing, Flat rate model. 1.0 Introduction A cyber café is a place where internet service is provided for public use, usually for a fee. These businesses usually provide snacks and drinks, hence the café in the name. The fee for a computer is usually charged on a timer clock, whether or not any upload or download is involved. Currently, the billing system adopted by cyber cafes for internet services is based on time (processor clock timing) or induced counter timer. This timing process could be and is always a cheat to the user who may not do anything due to delays, time out, low memory, low processor speed etc and have his/her time out. Services from the net should have been measured by the volume of packets in bits/second or bytes per minutes. Since the bandwidth is a dependent factor on bytes transfer. This work tents propose a billing system that is measured by the quality of bits/bytes transfer. In order to determine the amount of network resources to be reserved, traffic and performance descriptors must be defined. Allocated resources are used only when customers send or receive traffic, whereas when customers are inactive, resources may remain unused. Network administrators clearly prefer to charge users in proportion to the reserved resources, that is to say in proportion to the potential use of the service. Thus, network administrators can protect themselves against unfair user behavior. On the other hand, the charge would be unfair for customers. At the same time, it is objectively difficult for users to predict their traffic rate process exactly, so that they consider it convenient to pay for the resources they actually use, rather than for estimated (and eventually overestimated) resources. Note that, in some cases, the bandwidth reserved and left unused can be re-assigned to other traffic, just as in the case of the best effort service, by means of intelligence link sharing mechanisms (e.g., the well-known Weighted Fair Queuing). 1.0.1 Background to Study The first internet café started with the opening of the cyber café called café cyberia in London (UK) on September 1st 1994. Eva Pascoe is the founder of the internet café; she was working on her PHD at that time when she got the idea of mixing sipping coffee to surfing the web while she was sitting at one of the coffee shop near the city university in London. Café cyberia as it was formerly called started with half a dozen HP computers, connected to the internet through a dial- up modems that were to transfer data at 9.6 kilobits per second. Information and Communication Technology (ICT) development is rapidly coming up in developing countries. India for instance, has about 50,000 internet cafés and over 500,000 customers each month has compared to Nigeria. The World Wide Web (WWW) became available in Nigeria in 1996, while the full internet services became available in 1998, and the number of NCC (Nigerian Communication Commission) licensed internet services provider rose to over 150 by 2001 (Adomi, 2005). In late 2003, Nigeria had a total of 750,000 internet users and 60 users per 10,000 inhabitants representing 0.5 percent of the population (ITU, 2004). Nigeria had a total of 853,000 PCs and 0.71 PCs per 100 inhabitants as at 2003 (ITU, 2004).As a matter of fact, Adomi ( 2003) stated that the first cyber café in Delta state set up in 1999 and by 2001, there were nine (9) of them and by 2003, there were 18 of them. This number has increased tremendously all over Nigeria
