With the development of SOA based on web services, there are more and more web services with same interface and similar function. How to find and choose the best web service is an important problem that all SOA enterprises face. QoS is used to describe the quality criteria of a web service. In this paper, a new algorithm of web service hierarchy base on QoS similarity has been proposed, which is concerned with meeting requirements of service consumers and the satisfaction with load requirement.

In distributed systems, the server placement problem in which a new server has to compete with existing servers for user requests is important in planning of constructing new business service sites. In addition to minimizing cost, competition-aware server placement also needs to maximize the benefit of building a new server. This paper proposes a Tabu Search approach to optimize the problem in general graphs. Results from the simulation experiments show that it do has a better performance than both of the GreedyAdd and GreedyRemove algorithms. © 2011 IEEE.

BitTorrent(BT) has emerged as one of the most popular protocols for content sharing in recent years. Most BT applications are network-oblivious which brings great challenges to traffic engineering. As basic input information, network-wide BT traffic distribution is of vital importance for service providers (SP) or carriers to enforce appropriate control policies. Direct online measurement of network-wide BT traffic faces scalability issue, for it requires deploying application identification deep packet inspection (DPI) device on every subject link. In this paper, we propose a novel approach to estimate network-wide BT traffic distribution through combining sFlow and Tracker traffic analysis. Owing to a noticeable increase of BT traffic using random port numbers, sFlow alone is no longer sufficient for BT recognition. We tackle this problem by combining sFlow with information collected from BT tracker's traffic. With assistance of this information, BT samples can be accurately distinguished from other sFlow samples. The efficacy of our approach is evaluated through experiments on backbone links of campus network. Evaluation results show that our approach can reach a high accuracy in network-wide BT traffic estimation. © 2011 IEEE.

The rapid growth of new information services, especially like new media services, providing content distribution to clients with good quality of service(QoS) while retaining efficient is a great challenge. This paper investigates the QoS-aware replica placement problem (QRPP) for distributed caching system. We propose a dynamic programming algorithm for the problem in general graph, it first ensures the QoS requirement is satisfied of each request, then places the replica along the request forward path to minimize the total cost. The simulation results show the dynamic programming algorithm can achive a good balance between the access latency and the requested availability. When the request is more concentrated, the dynamic programming algorithm can have better performance than the MODULO and LRU both in access latency and requested availability.

Propose an evolution model for Peer-to-Peer (P2P) file-sharing systems, which try to capture the dynamic properties of P2P application networks. The model consists of four events: node joining, node departure, connection establishing and connection breaking, which captures the most important events in constructing network topology. The evolution model results in a differential equation about degree distribution, which can be solved analytically. By analyzing the solutions, some interesting results can be got.

With widely application of Peer-to-Peer (P2P) file sharing technique, the P2P traffic occupies most of the current Internet bandwidth. Modeling the behaviors of P2P file sharing systems is important for designing and evaluating such systems. In this paper, we develop a novel model to character the dynamic behaviors of P2P sharing systems. States in microcosmic view are defined and used to describe the interaction among the peers in systems. Then, a model in general form for P2P sharing systems is proposed. According to common software policies in P2P systems, we embody the model. To verify the validity and reasonability of the proposed model, P2P simulations are conducted.

Paraphrase generation aims to generate semantically consistent sentences with different syntactic realizations. Most of the recent studies rely on the typical encoder-decoder framework where the generation process is deterministic. However, in practice, the ability to generate multiple syntactically different paraphrases is important. Recent work proposed to cooperate variational inference on a target-related latent variable to introduce the diversity. But the latent variable may be contaminated by the semantic information of other unrelated sentences, and in turn, change the conveyed meaning of generated paraphrases. In this paper, we propose a semantically consistent and syntactically variational encoder-decoder framework, which uses adversarial learning to ensure the syntactic latent variable be semantic-free. Moreover, we adopt another discriminator to improve the word-level and sentence-level semantic consistency. So the proposed framework can generate multiple semantically consistent and syntactically different paraphrases. The experiments show that our model outperforms the baseline models on the metrics based on both n-gram matching and semantic similarity, and our model can generate multiple different paraphrases by assembling different syntactic variables. © 2020 COLING 2020 - 28th International Conference on Computational Linguistics, Proceedings of the Conference.

This paper discusses system models of three types of signal in wireless communication, i.e. single user single antenna signal, virtual MIMO signal and single user MIMO signal. Based on the model, proposes a method for blind identification of uplink virtual MIMO signal by using the MUSIC algorithm to blindly estimate DOAs of the received signal. Simulation results show the feasibility of this method. This approach has important value in both theory and application for noncooperation communication environment. © 2008 IEEE.

In the paper, a neurodynamic-based energy efficiency optimization strategy(NEE-OS) is proposed to decrease the energy expenditure of robotic manipulators. Different from the traditional approaches, the proposed NEE-OS integrates several necessary constrains from the environment and the robotic manipulator, which could affect energy consumptions of the robotic manipulator in engineering applications to a large extent. To handle the constraints formulated as equalities and inequalities, the energy efficiency optimization problem is converted into a constrained quadratic programming(QP) problem, which is solved using a linear variable inequality-based primal-dual neural network(PDNN) efficiently.
