The Research Of QoS Policy Deployment In The Industry Dedicated IP Network

With the popularity of IP technology, each industry continued to establish its own dedicated IP network (such as a bank, post office, railway and other dedicated IP network) for supporting the efficient conduct of the work within the industry. However, the traditional IP network provides only best-effort delivery service, cannot guarantee the real-time and reliability of information transmission. The emergence of QoS (Quality of Service) technology ensure providing high quality services in an IP network to become a reality.Although multiple organizations at home and abroad have been carried out the QoS technology research as well as related standards, but so far, there is no uniform standards of QoS technology to be able to meet all network, and we need to develop the whole network QoS deployment scenarios for a specific network.Based on in-depth analysis on QoS requirements in an industry dedicated IP network, the paper demonstrated the designed end-to-end QoS deployment scenarios of IP dedicated network, and analyzed QoS deployment strategy at various levels of network. The paper made Huawei network equipment as experimental subjects and designed the template of QoS strategy about specific configuration. A particular industry IP dedicated network has deployed the QoS deployment scenarios and specific strategies in accordance with the paper, which improved the QoS deployment scenarios and specific strategies are reasonable and correct.
