Thus they have achieved progress and breakthroughs in all aspects of their work and safeguarded China’s rights and interests and its foreign trade reputation. According to statistics, some 1.888 million batches of import and export commodities were inspected in 1996, worth us$91.82 billion——19.95 percent and 16.20 percent increase respectively over the previous year. Of these, export commodities accounted for 1.展开更多

The commodity inspection organs at all level adhere to the work policy of guaranteeing quality and offering better service, making import and export commodity quality as their central task. They strictly implement national laws and regulations to serve commodity inspection and management, thus achieving great success.展开更多

The supervision during the quality guaranteed period includes the monitor of the operation and maintenance of power plant,organization of subcontractor to treat the problems and defects occurred in the field in time, technical consultancy and communication in time, delivery of spare parts, and assistance of clearing Contractor’s quality deposit. It is proved by the practice that it is necessary to early out the supervision during quality guaranteed period.展开更多

The proposed scheme combines the admission control and bandwidth reservation to guarantee QoS requirements. It considers both local information and remote information to determine whether to accept or reject a connection. In order to embody the characteristics of the algorithms proposed in the article, two traditional algorithms of admission control are used for comparison. In the end of the paper the simulation analyses are given and the results show that the proposed algorithm can adjust the bandwidth according to the current status of networks and decrease the probability of connections forcibly dropped. The most important thing is that the algorithm is based on the multimedia communications and can guarantee the QoS of real time connections through decreasing the bandwidth of non real time connections.展开更多

However,most proposed DBA schemes ignore the quality of service（QoS） guarantee on maximum delay and delay jitter for the real-time traffic and the downstream bandwidth utilization under light upstream load in EPON. In this paper,a new DBA scheme,QoS guaranteed adaptive downstream bandwidth utilization（QoS-ADBU）,is proposed. This scheme can provide better QoS assurance by determining the maximum transmission cycle time according to the maximum acceptable packet delay and delay jitter for real-time traffic. Besides,the downstream utilization can also be improved by adapting the polling frequency to downstream traffic load.展开更多
