Due to the work nodes, not many integrated management of equipment and users. At the same time, work can quickly locate fault. The IP address of theft, IP address conflicts, a reasonable choice of work management toll-collection devices has e the consideration of priority. Use of advanced technology, restrict user unreasonable, prevent work applications use of unlimited bandwidth, such as the use of export, etc, to avoid its work congestion, export decline in the quality. The domestic leading x agreement with authentication solutions and x protocol realized with feature, switch of secondary certification scheme and mixed certification scheme, ensure the safety authentication and more widely. For billing and operation have different groups of users access features, guarantee the accuracy of the work, operation. Good customer relations management system, and effectively protect the user'work investment and after-sales service. Network gateways authentication billing solutions use efficiency, professional development of real-time operating sy
