As optical networking becomes a promising choice to meet the ever-increasing demands on bandwidth, constructing multicast wavelength division multiplexing (WDM) switching networks with cheap components and low complexity is a key issue. On the basis of three-stage Clos network, we propose an optimal model of strictly nonblocking multicast (SNBM) WDM optical switching networks. Our analysis shows that...
When match against Chinese keyword for network content audit, one of the biggest problems is that there is interference of ??noise characters??, it makes the traditional way using explicit string pattern to match infeasible. Regular expression matching can solve the problem perfectly, but the DFA-base approaches for regular expression matching will also encounter the problem of excessive memory usage...
In this paper, we have designed DOTP (distance of two points) algorithm and some data structure to calculate the shortest distance between the two vertices in Euclidean network. We created a function which had a linear relation with vertices n and edges e in time complexity. This algorithm's time complexity majority related with non-tree edges t which defined in chapter 2 and has a small magnitude...
In this paper, research for the cell search of the LTE TDD system and the initialization of carrier frequency offset estimation algorithm, theoretical derivation is given from timing synchronization and sector ID detection algorithm. In this work, simulated and researched the performance of cell search algorithm in the spread of multi-path environment. Through the method of analyze the complex and...
Stochastic fairness queuing scheduling scheme resolved the connection level fairness problem and are widely used in traditional network, however, with rapid development of P2P services in Internet, this classical algorithms failed in maintaining fairness among hosts. In this paper we proposed an improved SFQ algorithm: Dual Class SFQ to ensure the fairness among hosts using different type of services...
