The architecture is designed based on a highly parallel CRC algorithm. The algorithm first divides a given message with any length into bytes. Then it performs CRC computation using lookup tables among the divided bytes in parallel. At last, the results are XORed to obtain the CRC value of the given message. The algorithm is table-based and can accelerate different CRC algorithms. Based on the algorithm, the architecture is designed to accelerate CRC algorithms with high parallelism and flexibility. The architecture is configurable and can support CRC algorithms such as CRC32, CRC24, CRC-CCITT, CRC16, CRC8. CRC value of 128-bit input data can be generated in one cycle. Our method also allows calculation over data that is less than 128-bit wide without increasing hardware cost. With 128-bit input each clock cycle, the throughput of the proposed architecture reaches up to 100 Gbps by utilizing 16 KB SRAM (Static Random Access Memory) with about 12% area reduction compared with previous work.","PeriodicalId":193630,"journal":{"name":"The 21st IEEE International Workshop on Local and Metropolitan Area Networks","volume":"2 37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122577840","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}

In order for the FSD to achieve optimal performance, the number of full expansion (FE) stages should be sufficient, which is the major cause of the increase in the computational complexity when either a large signal constellation or a large number of antennas are adopted. However, the proposed algorithm maintains the near-ML performance with the aid of the MMSE-based LR algorithm while reducing the number of FE stages. Although there exists the increase in the computational complexity for the application of the additional processing elements, the decrease in the number of FE stages results in the lower computational complexity of the overall algorithm. The numerical analysis demonstrates that there is a considerable decrease in the computational complexity while the performance degradation is negligible, compared to the optimal FSD.","PeriodicalId":193630,"journal":{"name":"The 21st IEEE International Workshop on Local and Metropolitan Area Networks","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125154394","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}

They adopt 3GLTE protocol after slight modification. Handover is directly triggered from a UE (User Equipment) to a target BS (base station) to shorten the handover period though it is relayed on a serving BS in conventional systems while drawing large latency due to backhaul communications. The direct request uses SR (Schedule Request) signal on PUCCH (Physical Uplink Control Channel) of 3G-LTE protocol. This can be allowed by short propagating delay in a small cell and synchronous operation of all BSs under clock of PON (Passive Optical Network) used for the backhaul network. Handover resources like SR codes, downward frames, and terminal ID are reserved among the target UE and a group of BSs next to one serving the target UE before handover. Cells surrounding the target UE follow the move of the UE always confining the target UE in the cells with the reserved handover resources.","PeriodicalId":193630,"journal":{"name":"The 21st IEEE International Workshop on Local and Metropolitan Area Networks","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116014533","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 content-centric nature of Internet usage highlights the limitations of the host-centric model in coping with dynamic content-to-location binding, mobility, multicast, multi-homing, etc. If transmission capacity speedups in the backhaul may hide inefficiencies in the short term, the hostcentric communication model needs to be revisited to sustain future mobile demand. In this paper, we first identify and quantify the opportunities for backhaul evolution by analyzing a large set of traffic measurements collected between mobile core and backhaul of Orange France. The analysis reveals that 50% of HTTP requests are cacheable and traffic can be reduced from 60% to 95% during the peak hour by using 350GBs to 1TB of memory overall. Motivated by such significant opportunities for latency reduction and network cost savings, we present a solution based on Information-Centric Networking (ICN). First results of a large scale experimentation with 100 Linux servers and customized software, in a realistic network setting, provide a glimpse into ICN gains even under naive caching: a factor three reduction in delivery time and almost 40% bandwidth savings, when compared to existing alternatives.","PeriodicalId":193630,"journal":{"name":"The 21st IEEE International Workshop on Local and Metropolitan Area Networks","volume":"365 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115979877","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}
