We consider the problem of routing and resource allocation in a multi-layer network loaded by a combination of constant bit-rate (CBR) and variable bit-rate (VBR) traffic streams. One scalable heuristic method that addresses this problem is the multi-layer market algorithm (MMA). In this paper we focus on two validation benchmarks of MM A by Integer Linear Programming (ILP). The first is based on...
Three partssuch as: EPC middleware, ONS and EPC Information Service were studiedin depthin this paper. And an EPC Middleware System, an ONS system, an EPC Information Services ystem were designed and implemented. Thus more complete information network system hasbeen established, which providesa platform for “Internet of Things” rapidly extended to the enterprise and information-sharing among enterprises...
Weblog is widely used, and the number of users is increasing rapidly. Weblog reflects every aspect of the society, such as politics, economy and culture, so the topic relevance retrieval research on Weblog becomes necessary. Because of a lot of noise in the corpus and it is usually difficult to obtain the appropriate query, the common methods sometimes fail to reach an acceptable precision. We design...
Blog Distillation is the process of finding a blog with a principle and recurring interest. In this paper, two baselines are used to validate the results of our experiments. A set of features of individual feed is firstly constructed by decision tree to represent the similarity distribution of every feed against certain interest. Features are then selected by computing their centroid distances to...
To support large-scale Internet-based broadcast of live streaming video efficiently in content delivery networks (CDNs), it is essential to implement a cost-effective overlay multicast mechanism by exploiting peer-to-peer distribution capabilities among end hosts. This way, the access bandwidth demand on CDN servers in the multicast overlay backbone can be largely reduced. Such a streaming infrastructure...
This paper is to introduce an algorithm to cluster Chinese short texts for mining web topics based on Chinese chunks. Aiming at the characteristics of Chinese short texts, the algorithm employs N-gram feature extraction to capture Chinese chunks from texts, which reflect the text semantic structure and character dependency. Then RPCL algorithm is applied to realizing text clustering with high precision,...
Placing multicast proxies on the Internet can largely reduce the delivery delay of Internet live media streaming using overlay multicast mechanisms. In this paper, we propose a new approach to address the issue of proxy placement in an overlay multicast network. The task is to decide an optimal placement of multicast proxies in the overlay multicast network so as to minimize the average end-to-end...
