MP-Start:bandwidth measurement based and phase-divided TCP slow start mechanism by DENG Xiao-heng1, CHEN Zhi-gang1, ZHANG Lian-ming1, ZENG Bi-qing1

“…To set appropriate threshold value（ssthresh） of slow start and eliminate network oscillation caused by bursty traffic,a new measurement-based and phase-divided slow start mechanism was proposed,which was called MP-Start.MP-Start employs effective online bandwidth measurement technology to update the ssthresh with appropriate value dy-namically,and adjusts the increment of congestion window（cwnd） in different phase of the startup.MP-Start increases cwnd with half of the difference between ssthesh and cwnd,iterates and gradually closes up ssthresh,of which the incre-ment is small at start phase and end phase and comparatively large at the middle phase of the startup of a connection,the largest increment is no more than one quarter of ssthresh.In order to improve the performance of this algorithm,a flexi-ble parameterized model and an adaptive parameter setting solution are designed.And series simulation experiments in-dicate that MP-Start significantly decreases dropped packets,data transforming time,packet queue length of shared link,and also improves network performance and smoothness of connections.…”

Survey of FPGA based recurrent neural network accelerator by Chen GAO, Fan ZHANG

“…Recurrent neural network(RNN) has been used wildly used in machine learning field in recent years,especially in dealing with sequential learning tasks compared with other neural network like CNN.However,RNN and its variants,such as LSTM,GRU and other fully connected networks,have high computational and storage complexity,which makes its inference calculation slow and difficult to be applied in products.On the one hand,traditional computing platforms such as CPU are not suitable for large-scale matrix operation of RNN.On the other hand,the shared memory and global memory of hardware acceleration platform GPU make the power consumption of GPU-based RNN accelerator higher.More and more research has been done on the RNN accelerator of the FPGA in recent years because of its parallel computing and low power consumption performance.An overview of the researches on RNN accelerator based on FPGA in recent years is given.The optimization algorithm of software level and the architecture design of hardware level used in these accelerator are summarized and some future research directions are proposed.…”

Extensible hierarchical codec semantic communication system by Yuyuan ZHANG, Haitao ZHAO, Jibo WEI, Kuo CAO, Yichi ZHANG, Peng LUO, Yueling LIU, Kai MEI

“…Aiming at the problem that most current researches on text semantic communication mainly rely on simulation system for theoretical verification, an extensible hierarchical semantic communication system was proposed by taking advantage of the separation of hierarchical encoding and decoding architecture in semantic level and grammatical level.The system was compatible with the reliable communication technology under the framework of Shannon information through the mode of semantic and syntactic separation, and realized the nested combination of semantic communication and traditional communication.Furthermore, a universal and extensible verification system was built based on the software radio platform to verify the proposed semantic communication system architecture.The verification system took semantic communication software platform as the driving core of hardware drive and algorithm call, integrated the whole process of signal generation, information transmission, data acquisition, decoding and evaluation at the receiving end, and could be further extended for semantic and syntactic level.Finally, the text semantic communication was tested based on this verification system, which verified that it had higher validity and reliability than the traditional communication mode.…”

Multi-version consolidation method for block-level backup data by WANG Shu-peng 1, WU Guang-jun1, WU Zhi-gang3, YUN Xiao-chun1

“…Historical version backup data query efficiency was dependent on the version chain length in a multi-version backup data storage system.A novel block-level backup data multi-version consolidation method was presented for this problem.Any version of a historical full system snapshot could be generated within the incremental backup data version sequence.Theoretical analysis showed that it could increase the target snapshot version query efficiency significantly in the version chain.A variable-length block version merging algorithm was presented to decrease the computing complex-ity in the process of snapshot version merging,according to the block-level backup data distribution features.Finally,the concrete applications and performance analysis for block-level version consolidation method was also introduced.The simulated experiments results expose that the version consolidation method can eliminate redundant version of backup data with the same version chain length,and it can increase full system recovery efficiency than traditional methods sig-nificantly.…”

Malicious domain name detection method based on associated information extraction by Bin ZHANG, Renjie LIAO

“…To improve the accuracy of malicious domain name detection based on the associated information, a detection method combining resolution information and query time was proposed.Firstly, the resolution information was mapped to nodes and edges in a heterogeneous information network, which improved the utilization rate.Secondly, considering the problem of high computational complexity in extracting associated information with matrix multiplication, an efficiency breadth-first network traversal algorithm based on meta-path was proposed.Then, the query time was used to detect the domain names lacking meta-path information, which improved the coverage rate.Finally, domain names were vectorized by representation learning with adaptive weight.The Euclidean distance between domain name feature vectors was used to quantify the correlation between domain names.Based on the vectors learned above, a supervised classifier was constructed to detect malicious domain names.Theoretical analysis and experimental results show that the proposed method preforms well in extraction domain name associated information.The coverage rate and F1 score are 97.7% and 0.951 respectively.…”

Research on video streaming media cooperative downloading in vehicular ad hoc network by Liang CHEN, Jun WANG, Rong CHEN, Xiang GU, Jin WANG, Jie WAN

“…The same direction multi-hop downloading network flow model was proposed for vehicle communication range and channel competition under forwarding.According to the model and video streaming media characteristic,the same ＆amp; opposite direction cooperative downloading quality of service (SODCD-QoS) scheme was presented.First,the same direction vehicles helped the target vehicle to achieve multi-hop cooperative downloading.It can reduce the waste of time which the target vehicle has to wait for opposite direction cooperative vehicle.Secondly,the next base stations loaded data into eligible opposite direction vehicles according to vehicles option strategy based on time first or picture quality first.Then the opposite direction vehicles helped the target vehicle to achieve one-hop cooperative downloading.NS simulations show that the SODCD-QoS scheme is better than DSRelay and VCoDS algorithm in terms of download time.Further,the new scheme can maintain good picture quality PSNR.…”

A mobility support method based on ELM prediction for named data networking by Hua QU, Yansong LI, Jihong ZHAO, Dongxu ZHAO, Jianlong ZHAO

“…Named data networking (NDN) is a new generation network architecture under the guidance of information center network,and the mobility support method is the main research point in NDN.In the traditional way of the producer-side mobility support method,the post-response mode is adopted,which makes it impossible to realize the transparency of the switching process.A mobility support method called PB based on ELM prediction was proposed.In the method,the original forwarding interest base was modified and a new control message packet was added so that the corresponding node in the network could adjust the result of the prediction algorithm in advance,and the switch of the producer terminal could respond to the interest package at any time by means of interest packet multicast.At the same time,the method provided a way to quickly restore the original state of the network for the problem that the prediction may fail.The simulation results show that the proposed PB mobility support method can reduce the handoff latency and the packet loss caused by handoff compared with the RP and IP mobility support methods.…”
