In recent years there has been an explosion of applications that use enormous amounts of data. Disk arrays are today's standard solution for enterprise class storage systems.

The model is created as a closed fork-join queue network (CFJQN) under synchronous I/O workloads.

However, Ethernet fabric is still widely used which has different characteristics in protocol and performance. Therefore, an Ethernet-to-InfiniBand gateway must be built to implement protocol conversion and bandwidth aggregation. This paper introduces a software implementation of Ethernet-to-InfiniBand gateway based on IPoIB protocol. Moreover, several network test tools are compared and used to evaluate the performance of IPoIB gateway. Performance evaluation results show that IP fragmentation operations and high CPU utilization of software interruption are the bottlenecks of the system, and they are good references for the design of hardware Ethernet-to-InfiniBand gateway","PeriodicalId":439264,"journal":{"name":"2006 International Workshop on Networking, Architecture, and Storages (IWNAS'06)","volume":"20 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":"121956573","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 this paper, we propose a routing protocol, called Hint-based Routing by Scope Decay Bloom Filter (HR-SDBF), that employs probabilistic hints. In HR-SDBF, each node maintains some probabilistic hints about events and utilizes these hints to route queries intelligently. We also put forward a data structure, scope decay bloom filter (SDBF) to encode the probabilistic hints. With SDBF, the amount of information about an event is propagated, without any loss, within the k-hop neighborhood of an event source but decreases outside the k-hop neighborhood as the distance from the event source increases. Compared to existing query-based protocols, HR-SDBF greatly reduces the amortized network traffic without compromising the query success rate and achieves a higher energy efficiency. To the best of our knowledge, this is the first query routing protocol in WSNs that utilizes probabilistic hints encoded in a variant of the bloom filter. Both the analytic and the experimental results support the performance improvement of our protocol","PeriodicalId":439264,"journal":{"name":"2006 International Workshop on Networking, Architecture, and Storages (IWNAS'06)","volume":"92 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":"128811161","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}
