Abstract

The paper presents a new approach for Bandwidth control in Broadband Access Networks, especially Digital Subscriber Line (DSL) and Cable Internet (DOCSIS) users. The basic idea is to have a broadband line to the server receiving all the incoming bandwidth. The approach is to have bandwidth division among various VLANs in a network connected via a switch to a centralized server. This approach can be implemented either in an institution where the amount of bandwidth to each department falling under one VLAN can be allocated proportional to the usage and requirements or in an industry where bandwidth needs to be allocated to various divisions. The concept of giving bandwidth according to the VLAN has been made to enhance security and ensuring that the traffic of one VLAN reaches that particular VLAN only. The basic idea is to have a broadband line to the server receiving all the incoming bandwidth. The server then queue the packets according to the VLAN id. The VLAN id of some department having paid for higher bandwidth or having more importance will be given higher priority at the server. All packets belonging to a particular VLAN will be queued in the same queue. The VLAN having higher precedence will have more of its packets sent than the other queues to ensure that the VLAN which was allocated higher bandwidth will receive that bandwidth. The idea is to have VLANs spread across multiple switch yet providing the proportionate bandwidth to each VLAN and also provide mobility to each member of VLAN. Some end users who are of interdisciplinary departments will be members of two or more VLANs.
