The scheduler has one classifier which classifies the flows into aggressive and normal flow. Aggressive flows are treated as high priority flows. Based on the buffer occupancy threshold, a trigger handler checks for load un-balance of the network and automatically triggers the load adapter. The load adapter reroutes the high-priority aggressive flows into the least loaded best path, using the bursty traffic splitter algorithm. The bursty traffic splitting algorithm splits the aggressive flows over multiple parallel paths, based on a split vector. In this algorithm, instead of switching packets or flows, it switches packet bursts. Since the packet bursts are smaller in size, the algorithm splits the traffic dynamically and accurately. At the same time, the condition forced on their latency difference, ensures that no packets are reordered. To achieve fair bandwidth allocations, load balancing is attained in the system since the high-rate aggressive traffic flows are splitted along multiple parallel paths. The proposed switching technique is executed in the edge and core routers. We will show by simulations, that our adaptive packet scheduler performs better than the standard fair-queuing techniques.","PeriodicalId":342396,"journal":{"name":"2009 2nd IEEE International Conference on Computer Science and Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130095180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The zig-zag scan is used for transform coefficients in frame macroblocks (MBs), and the field scan is used in field MBs. This paper presents a most probable scan mode (MPSM) decision for H.264 inter picture coding. Besides the two scans, a horizontal scan is illustrated. For a 4×4 block, one out of the three scan modes is selected as the most probable one, and is used for the transform coefficient scan. Furthermore, an improved MPSM decision is discussed. Simulation results report that the proposed method yields an average of 1.15% bit rate reduction over the H.264 baseline profile.","PeriodicalId":342396,"journal":{"name":"2009 2nd IEEE International Conference on Computer Science and Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130178566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous researches just use original series to establish models but not fully discover information content of time series signals. Taking China's citrus trade for example, the paper uses wavelet analysis to decompose production cost and export price into four series, which are trend, cycle, volatility and noise. After filtering noise, the paper forecasts the influence of trend, cycle and volatility of production cost on that of export price by using impulse response and variance decomposition which are based on VAR. Results show that in the long run, change trend and cycle of production cost's influence on that of export price is very significant, but the volatility of production cost's influence on that of citrus export price is very small.","PeriodicalId":342396,"journal":{"name":"2009 2nd IEEE International Conference on Computer Science and Information Technology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127951526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
