However, many recent studies equate host availability with data availability and calculate data availability based on the traditional definition of host availability. By analyzing the trace of live P2P system, we argue that there is a significant difference between them and it is far more inaccurate and misleading to use host availability to evaluate data availability because of peers' incentives and rationalities. To achieve a precise data availability evaluation, firstly, we present an evaluation model which combines peers' incentives and host availability together. Furthermore, we illustrate that the traditional definition of host availability has serious drawbacks because it ignores the effect of time of day and peers' different online pattern. So we improve the accuracy of our model by considering both factors. Finally, we introduce how to implement this model in practice and propose some its applications to P2P storage systems","PeriodicalId":439264,"journal":{"name":"2006 International Workshop on Networking, Architecture, and Storages (IWNAS'06)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121240902","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}

Existing traces available, however, are unsuitable for studying object-based storage system, a very active area of current storage research, because they are collected from the traditional file systems and don't contain information about object. Thus, a kind of distributed object tracing system is presented in this paper which built on the object-based Lustre file system. The tracing system regards object as capturing unit which we also call it object-trace. Objects information is synchronously captured from three software subsystems of Lustre cluster file system, and eventually integrated into one entire trace for every request of each user. To improve I/O performance and efficiency, we employ a ring of buffers to store trace data which finally is written out to a trace file by an output driver. In particular, we use some database tables to save the final incorporated traces for convenient post-analysis. A prototype of object tracing system is designed and implemented on Linux","PeriodicalId":439264,"journal":{"name":"2006 International Workshop on Networking, Architecture, and Storages (IWNAS'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130867188","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 OBS will become the next wave of network storage technology. In this paper a framework for accessing general object storage (GOS) is presented. The GOS system adopts a basic unit called storage device object (SDO) and proposes an access model that contains upper layer, middle layer and lower layer. It not only enriches the concept of object, but also gives a compatible object interface in the network storage systems. So it allows applications to access to different SDO according their attributes.

Typically, conventional data center uses multiple network adapters to build the server fabric, which bring many drawbacks, such as complex management, hard scalability and expensive cost, and so on. Fortunately, InfiniBand provides a high-bandwidth, low-latency network, and it has been widely used in current data center to create a unified fabric. However, fiber channel and IP fabric are still widely adopted so that many researches have been focused on connecting between InfiniBand and conventional networks. Many methods, such as protocol conversion and bandwidth aggregation, have been proposed to eliminate performance limitation caused by heterogeneous fabrics. Nevertheless, diversity and dynamic requirements of server I/O on data center still didn't be considered. This paper proposes a novel heterogeneous interconnect architecture called RGAMF (reconfigurable gateway array of multiple fabrics), which has five major features: protocol conversion, bandwidth aggregation, virtual service mapping, dynamic reconfiguration and redundant array. Through verification and evaluation, latency of RGAMF is between 1us and 2us, and the bandwidth of all IP links is close to wire speed at 1Gbps in both directions. Based on the FPGA (field programmable gate array) embedded in each gateway of array, this architecture also provides better flexibility and scalability","PeriodicalId":439264,"journal":{"name":"2006 International Workshop on Networking, Architecture, and Storages (IWNAS'06)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129667281","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 performance of scheduling algorithm influences the performance of the whole system. Real-time embedded operating system needs better response time for real-time process; it is more rigid on response time for hard real-time embedded operating system. A high-performance scheduling algorithm is required in order to make embedded operating system more efficient. Most of the mainstream scheduling algorithms are able to ensure response time for most processes, but for specific real-time applications for embedded system, a specialized real-time scheduling algorithm is required to ensure real-time response.
