ROUTER AND METHOD FOR PROVIDING DIFFERENT BANDWIDTH SERVICES FOR DIFFERENT IP GROUPS

摘要

A router for providing different bandwidth services to different Internet protocol (IP) groups and a routing method thereof are provided. The router includes a plurality of queues supporting different bandwidth services to allocate predetermined different bandwidths to different IP groups. The routing method includes the steps of classifying IP addresses of a plurality of devices constructing a sub network into a predetermined number of IP groups; setting different bandwidth services for the different IP groups; if data is input through an external communication network, identifying an IP group to which the data is to be transmitted using destination address information contained in the data; selecting a queue supporting a bandwidth service set for the IP groups to which the data input in the above step is to be transmitted, from among the plurality of queues and storing the input data in the selected queue; and routing the stored data to a transmission line corresponding to the bandwidth service. Since differential communication services can be provide to different users, more resources and higher priority can be given to users using more important data, so that network resources can be more efficiently used.
