The software streaming technology enables telematics software to be automatically updated through a wireless network. When the software starts running, software streaming system inspects its version and then, automatically download latest one. The software streaming system breaks the software into several pieces that are streamed to the user as needed. In this way, software streaming system can improves the telematics application load time while updating the software through wireless network. In our experiments, the application load time was reduced about 7 times compared to downloading whole software at best case.

Network streaming technology is a service method which can support several application software via streaming in networks. Although multimedia streaming technology has been developed and widely used, research on the software streaming technology is not yet being progressed actively. In this paper, we design and implement a software streaming technology based on Java language with enhanced performance, compare the existing related systems with it and analyze several characteristics, and perform the performance evaluation. The implemented system has a platform to be used in multiple operating systems in addition to Windows system. It can also be used without installing a software at the client's computer, and has a novel feature that the user's convenience is maximized.

Software streaming technology is a service method which can support several application software via streaming in networks. In this paper, we propose a platform independent PESS(performance Enhanced Software Streaming) technology. We design and implement the technology based on Java language. The main features in the implemented system are both platforms to be used in multiple operating systems in addition to Windows system and enhanced performance. In the implemented streaming method, application software is placed on the server and only necessary packs are transmitted in an instant. By virtual file system and clients' virtual registry, if necessary, the users' request is processed by transmitting a very small pack unit. Therefore, server load can be reduced and the streaming speed can also be improved. We present the implementation results and evaluate several performance characteristics of the proposed system.

In this paper, I propose a load balancing algorithm based on the traffic characteristics of a software streaming service, and implement the proposed algorithm on the large scale software streaming server platform which provides a software streaming service to geographically dispersed internet users. By showing that the large scale software streaming server platform fuctions correctly, we know the proposed load balancing algorithm is operating properly and efficiently.

The need for ASP(Application Service Provider) has evolved from the increasing costs of specialized software that have far exceeded the price rage of small to medium sized businesses. There are a lot of technologies that make ASP possible, and software streaming service is one of them Software streaming is a method for overlapping transmission and execution of stream-enabled software. The stream-enabled software is able to run on a device even while the transmission/streaming of the software may still be in progress. Thus, a user does not have to wait for the completion of the software's download prior to starting to execute the software. In this paper, we suggest the new concept of software streaming system implement using the PageFault Interrupt Routine Hooking. As it is able to efficiently manage application, we do not have to install the entire software. In addition, we can save hardware resources by using it because we load basic binaries without occupying the storage space of the hardware.

As the demand of employing various PC software on mobile embedded devices which have limited storages has been increased, software streaming services are needed. However it takes too much time to launch software on them because it is transferred through wireless networks. To address this problem, prefetch algorithms are needed. We examined 'Last successor (LS)' algorithm and PPM-based prefetch algorithm as prefetch algorithms for software streaming services. We present 'Probability-base Multi Successor (PMS)' algorithm which is contrived through analyzing evaluations of previous algorithms and characteristics of software streaming services. While LS has one successor per each block, PMS has N successors based on probability which is calculated by PPM-based prefetch algorithm. The hit rate of PMS is similar to that of PPM-base prefetch algorithm and the space overhead is similar to that of LS. We can get good efficiency at the point of memory usage when PMS is applied to software streaming services.

Unreal Engine 5의 Level Streaming 기능은 플레이어가 플레이 도중 메모리에 Map을 로드/언 로드하는 등의 작업을 처리하는 기능이다. 이때 Level Streaming은 커다란 Map의 당장 필요한 부분에만 메모리에 로드하고, 렌더링하여 특히 Seamless Open world 장르에서 많이 사용된다. 본 논문에서 제안하는 방식은 이 Level Streaming 기능을 이용하여 현재 개발 진행 중인 Rogue-Like 장르 게임에서 비동기 방식의 로딩 화면과 Stage 전환을 통해 좀 더 부드러운, 즉 더 높은 Frames per Second(fps)를 플레이어에게 제공하기 위한 새로운 스테이지 시스템의 구현방식을 연구한다.

As the development of networks and computer systems, users want various services. To meet user's various needs, new technologies is developed and a software streaming technology, uses software with streaming technology, is newly coming out. If network trouble occurs, the software is not available because the streaming server can't send the binary code that software needs to be executed in the streaming service based on network environment. In this paper, we propose the management technology of software binary code in client that managing the binary codes classfied by the function kept in the local storage device, provides the service continuously after the network trouble with the given binary code previously not the binary code from the server.

Software streaming allows the execution of stream-enabled software on desktop or portable computing devices like PC, PDA, laptop, cellular phone, etc., even while the transmission/streaming from the server may still be in progress. In this paper, we present an efficient streaming system called Software On-Demand(SOD) streaming system to transmit stream-enabled applications in addition to automatic installation of program registry, environment variables, configuration files, and related components. In particular, we design and implement a SOD system in Linux to provide the user with the instant look-and-click software execution environment such that software download and installation are internally proceeded in a completely user-transparent way. Therefore, the SOD system relieves the user from the tricky, failure-prone installation business. In addition, the software developer now obtains a new, powerful means to advertise and propagate their software products since the user can use software packages via user-friendly UI window or web browser by look-and-click interactive operation. In the paper, we also make a couple of SOD streaming experiments using a spectrum of popular softwares. Based on the analysis of the experiment results, we also propose two performance improvement schemes.
