With the development of Internet technology, network English teaching system came into being and developed rapidly. Based on optimized J2EE, this paper presents the implementation of sentence feature recognition in the English teaching system. Optimize the load balancing algorithm on the basis of cloud computing technology, and improve the teaching service providing ability of online teaching system based on J2EE. The technology integration of Sturts2, Spring, and Batis was realized to realize the persistence layer, business layer, and presentation layer respectively through the three frameworks. Then, the technology of Struts2 and Spring, Spring, and Batis software is integrated to analyze and build the current popular SSI lightweight framework, and RBAC is used to provide a security mechanism for the SSI framework. It establishes that the information system should adopt the mixed architecture of B/S architecture and C/S architecture, and then design the overall functional structure of the system with students, teachers, and administrators as the main users from the perspective of users. This paper analyzes and explains the overall structure of the J2Ee-based English teaching system, briefly introduces the overall framework of the whole website, and introduces the main functions of each functional module of the website. Finally, the English teaching system based on optimized J2EE statement feature recognition is implemented and tested. In the performance test of file resource query service with virtual 10-100 users and 20 times submitted by each user, the response time of the system is <1.5 s, the success rate reaches 100 %, and the CPU utilization is also <5 %. The memory usage is relatively high. When 2000 queries are concurrent, the memory usage reaches >160 M.

load balancing is a major challenge with today's ever increasing traffic. balancing huge amount of incoming requests is a huge concern. Although there are already a wide range of load balancing algorithms([1][2][3]) at our disposal, deciding the most appropriate one is what leaves the users confused. If the load is not handled properly, it can lead to the breakdown of the entire network within seconds. Hence a strong and methodological comparison([4][5][6][7]) is made in this paper considering various functionalities to be handled by a server.

In beyond 3G systems, one of the important factors is to address Radio access technology (RAT) selection and load balancing between heterogeneous networks to ensure high spectral efficiency in an era where spectral resources are at a premium. This work aims to address the feasibility of utilizing WiFi as complementary service for HSDPA, to prevent quality of service deterioration in the event of network overload in HSDPA during the busy period. The proposed RAT selection algorithm is based on the load of each system, and the results show that the outage probability can be improved by up to 45% relative to a stand-alone HSDPA system.

The defects of traditional WebGIS model and problems of current common load balancing algorithms are analyzed. A new WebGIS model based on response ratio priority scheduling algorithm is proposed. Based on the waiting time and executing time, the model can calculate the response ratio priority of all requests and select the highest one. According to the load capacities of map servers, the task which has the highest request priority will be submit to the map server which has the lightest load to process. In this paper, the weaknesses of the traditional WebGIS model such as lower parallel processing capability and inefficient load balancing algorithm are solved in the new model. At last, a test is built to verify the model's performance.

In recent years, combined input-cross-point-queued (CICQ) switch is a research hotspot on switches. CICQ is a switch fabric with buffers in cross-points. Although the existing round-robin algorithms of CICQ switch can achieve 100 % throughput under uniform traffic, the throughput have poor performance when the traffic model is non-uniform. In this paper, we proposed a load balancing algorithm based on round-robin algorithm (LB - RR). The proposed LB - RR algorithm can make any of the non-uniform traffic to uniform. The simulations show that the LB - RR can achieve the throughput nearly 100 % for any traffic model.

The Application of FSP Models in Automatic Optimization of Software Deployment

The correct deployment of software objects over the computational resources has a significant impact on the software performance. Achieving the optimal deployment manually is a tedious work as there are many different alternative solutions. In this paper a heuristic algorithm for optimizing the deployment of software objects is proposed which evaluates each deployment in the search space, considering its communicational and computational delays. In order to estimate these delays for an object deployment, our algorithm takes into account both the resource capacities and the execution load of the software for a given input-workload. The execution load of the software is measured by simulating the software use-case scenarios using the Finite State Process (FSP) models. From the simulation, the values of some metrics such as utilization, population and mean response times corresponding to the objects and threads participating in software use-case scenarios are recorded as the execution load indicators. These recorded simulation results are subsequently applied to estimate the goodness of a deployment in the search space.

We studied and compared the application areas of computer clusters with limited computing resources and well-known single-board computers. Existing solutions for calculating convolutional neural networks are analyzed. The possibility of implementing convolutional neural networks on computer clusters with limited computing resources has been established. The system implements an architecture that allows you to organize and distribute convolutional neural network calculations without dividing the convolution sphere into parts with load balancing taking into account the specifics of the data and resources processed on the cluster nodes. The developed algorithm for the application of convolutional neural networks by a computer cluster with limited computing resources makes it possible to use the developed forecasting models of convolutional neural networks to perform calculations in cyber-physical systems of the Internet of Things.

As one of the main technologies in 5G networks, Ultra-dense networks (UDNs) can be used to improve the network coverage. The dense deployment of small cells in UDN hotspots generates an uneven traffic distribution. In this paper, we propose a novel mechanism in order to transfer the extra users from the small cells to the macrocells based on several load balancing approaches implemented within the small cells, which are formed based on the Radio-over-Fiber (RoF) system. To select the best overlapping zone and then the best candidate user to be handed-over between the access points of the small cells, a common zone approach, a worst zone approach and a mixed approach are proposed. With the objective of transferring the extra users to the macrocells, we suggest a transfer after approach, a transfer before approach and an active approach. The simulation results indicate that the proposed approaches succeed to balance the load among the access points and to migrate the required load from the overloaded small cells to the macrocells in selective way. In some cases, the balance improvement ratio can reach 97.94%. Moreover, the overall balance efficiency is increased by 51.32% compared to the case without transferring users to the macrocells.

The natural calamity or disaster may destroy all communication networks especially a cellular network that relies on a tower. Although many solutions to an ad hoc wireless network have been proposed, forming a network covering a respective region with mobile robots toward optimal coverage remains to be an open problem. In this paper, we take the initiative to handle the optimal network coverage and path selection in disaster region with the help of multiple movable/rover robots. This paper consists of load balance distribution algorithm and optimal coverage algorithm applied to find the next optimally possible node location for all robots. Next, the robots maneuvering in an unknown disaster environment to identify the optimal path between the source and destination by using a particle swarm optimization algorithm. Finally, simulated results show that the algorithms can significantly improve the network coverage in the entire region, and the optimal path can effectively identify the optimal solution for all rover robots.
