Such a system should accommodate a variety of protocol suites yet present users with an integrated and uniform interface to all the protocols and, as a consequence, to all Internet resources. Toward this end, they have designed an operating system, called the x-kernel, that consists of three major components: a configurable kernel that provides uniform access to a wide array of protocols, a heterogeneous file system, and a customizable user interface. The central element in this design is the protocol. The kernel implements a library of useful protocols. The file system and user interface in turn, provide a per-user environment that translates a resource name into the protocol that should be used to access the resource. The authors describe the library of protocols, the file system and the user interface.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124017928","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 present version of ISIS is limited to relatively small-scale applications, containing fewer than 50 workstations. The principal idea is to incorporate hierarchy in the program structure and exploit this to limit the communication and storage required in any one component of the distributed program. This approach seeks to maintain the advantages of virtual synchrony, while controlling those costs that grow as the size of a distributed application increases.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130370490","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 author considers the usefulness of virtual memory, exploring what has changed in software and hardware since virtual memory was introduced. Programs are loosely divided into three categories, and the usefulness of virtual memory is assessed for each category. The costs in speed, product development, space, and money are discussed. The author deals with the question of what piece of software should be responsible for virtual memory decisions. He concludes that the user, programmer, or programming environment are better suited to provide this function than the operating system.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127863910","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}

It provides resilience to server and network failures through the use of two distinct but complementary mechanisms. One mechanism, server replication, involves storing copies of a file at multiple servers. The other mechanism, disconnected operation, is a mode of execution in which a caching site temporarily assumes the role of a replication site. Disconnected operation is particularly useful for supporting portable workstations. The design of Coda optimizes availability and performance and provides the highest degree of consistency attainable. Measurements from a prototype show that the performance cost of providing high availability in Coda is reasonable.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130394608","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 authors discuss how to use these messages to implement higher level primitives such as at-most-once remote procedure calls (RPC) and describe an implementation of at-most-once RPCs using their method. Performance measurements indicate that at-most-once RPCs can be provided at the same cost as less desirable RPCs that do not guarantee at-most-once execution. The method is based on the assumption that clocks throughout the system are loosely synchronized. Modern protocols provide good bounds on clock skew with high probability; the present method depends on the bound for performance but not for correctness.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"511 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123570063","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 authors describe the distributed file system they are developing, which is called FACE (file system for ACE).

User processes interact with the system call interface to perform file and stashing operations. These operations may be invoked directly by user processes or by the FACE user-level routines. The FACE user-level routines implement diverse facilities to allow users to select the files that will be stashed (or dropped from the stash).

Tradeoffs between consistency of replication and caching versus availability are considered for the Echo distributed file system which uses two different replication techniques, one at the upper levels of the hierarchical name space, the name service, and another at the lower levels of the name space, the file volume service. The two replication techniques provide different guarantees of consistency between their replicas and, therefore, different levels of availability. Echo also caches data from the name service and file volume service in client machines (e.g. workstations), with the cache for each service having its own cache consistency guarantee that mimics the guarantee on the consistency of the replicas for that service. The replication and caching consistency guarantees provided by each service are appropriate for its intended use.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123247371","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}
