On March 27, 2013, the Ministry of Land and Resources held a news conference to announce a significant achievement in Chinese geological prospecting work in 2012. According to government/industry statistics, proved reserves of oil and natural gas have increase substantially in 2012. Newly proven national petroleum geological reserves are 15.2 million tons, a year-on-year growth of 13%, which is the tenth time of more than 1 billion tons since the founding of People's Republic of China; newly proven technically recoverable reserves are 270 million tons, a year-on-year growth of 7%. The 2012 national newly proved reserves from natural gas exploration are 961.22 billion cubic meters, a year-on-year growth of 33%, which is the highest level in our history; the new proven technically recoverable reserves are 500.8 billion cubic meters, a year-on-year growth of 36%. National natural gas production was 106.76 billion cubic meters, a year-on-year growth of 5.4%. The Ordos, Tarim and Sichuan basins are still the main producing areas of natural gas in China. In 2012, national oil production was 205 million tons, a year-on-year growth of 1%, which made a steady increase. The national coal-bed methane production was 2.57 billion cubic meters, a year-on-year growth of 24%. 展开更多

This paper presents a lighter protocol, and it removes the multicast burdens from RSVP to adapt to unicast applications. At the same time, when RSVP is used in wireless networks, some issues about mobility raise popular concerns. The proposed protocol a lightweight mobile RSVP protocol, solves the problems by the following mechanisms: changeless flow identifier, a new state management and "refresh" mechanism. 展开更多

Distributed speech recognition (DSR) applications have certain QoS (Quality of service) requirements in terms of latency, packet loss rate, etc. To deliver quality guaranteed DSR application over wirelined or wireless links, some QoS mechanisms should be provided. We put forward a RTP/RSVP transmission scheme with DSR-specific payload and QoS parameters by modifying the present WAP protocol stack. The simulation result shows that this scheme will provide adequate network bandwidth to keep the real-time transport of DSR data over either wirelined or wireless channels. 展开更多

As one of the most promising next-generation access network (EPON) should pay more attention to its quality of service (QoS), techniques, the user-oriented Ethernet passive optical network However, now the EPON adopts mostly differentiated services model (Diffserv) that only provides quality control on traffic aggregation, whereas, the quality of user session cannot be guaranteed when the network is overloaded with substantial connections. This article proposes to apply integrated services model (Intserv) in Diffserv-based EPON, which uses per-flow processing to guarantee QoS. In the simulation, a framework of combined Diffserv and Intserv model is employed in an EPON system, with a dynamic bandwidth allocation algorithm that adapts to it. The simulation results demonstrate that the EPON system with the combined models can provide more flexible, various control for user-oriented service quality. 展开更多

Cooperation of multi-domain massively parallel processor systems in computing grid environment provides new opportunities for multisite job scheduling. At the same time, in the area of co-allocation, heterogeneity, network adaptability and scalability raise the challenge for the international design of multisite job scheduling models and algorithms. It presents multisite job scheduling schema through the introduction of multisite job scheduling model and the performance model under the grid environment. It introduces two job multisite and cooperative scheduling models and algorithms with the core of the optimal and greedy-heuristic resource selection strategies. Meanwhile, compared with single and multisite cooperative scheduling models and algorithms introduced by Sabin, Yahyapour and other persons, the validity and advance of the scheduling model and the performance model herein are proved. 展开更多

This article discusses the issue of resource conflict in the generalized multi-protocol label switching (GMPLS) controlled optical network. Based on the analysis of the current random rebuilding mechanism and its drawbacks, this article presents two enhanced solutions for improvement, namely, the priority-based resource allocation mechanism and the network management system (NMS) based sequential resource allocation mechanism. Experimental results show that the presented mechanisms perform better than the original random rebuilding solution in terms of the connection setup/recovery time and successful rate. 展开更多

It provides an alternative selection along with some well-provisioned clouds. However, for the uncertain time span that participants share their computing resources in voluntary cloud, there are some challenging issues, i.e., fluctuation, under-capacity and low-benefit. In this paper, an architecture is first proposed based on Bittorrent protocol. In this architecture, resources could be reserved or requested from Reserved Instance Marketplace and could be accessed with a lower price in a short circle. Actually, these resources could replenish the inadequate resource pool and relieve the fluctuation and under-capacity issue in voluntary cloud. Then, the fault rate of each node is used to evaluate the uncertainty of its sharing time. By leveraging a linear prediction model, it is enabled by a distribution function which is used for evaluating the computing capacity of the system. Moreover, the cost optimization problem is investigated and a computational method is presented to solve the low-benefit issue in voluntary cloud. At last, the system performance is validated by two sets of simulations. And the experimental results show the effectiveness of our computational method for resource reservation optimization. 展开更多
