Both specifications consider the general case of Web services as being black boxes with WSDL interfaces. In this paper, we address the reliable messaging requirements of composite Web wervices in BPEL. In such Web services, the BPEL programmer sees not only the WSDL interface but also the implementation, i.e., the process definition. BPEL processes have several reliable messaging requirements, which cannot be supported by current reliable messaging specifications. The most challenging of those requirements is to support ordered message delivery between many endpoints. Current reliable messaging specifications support only reliable messaging between two endpoints. This paper presents several approaches to support multi-party reliable messaging and introduces a reliable messaging Web service for BPEL that is integrated with a BPEL engine by using a process container framework. This Web service supports the reliable messaging requirements of BPEL processes and its implementation is based on Sandesha, which is an open source implementation of WS-ReliableMessaging","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126108245","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}

WIP is an entirely Web service based communication protocol, consisting of a set of Web service operations for initiating and establishing converged (e.g. multimedia, IM, voice, etc.) communication services over IP. It inherits the principle of separation signaling and media transmission of SIP (session initiation protocol); but it relies on a single Web service stack to provide a full featured communication signaling protocol. WIP opens a new paradigm of Web service based VoIP communication, which is extensible and can be easily integrated in end-to-end SOA solutions. The generic Web service approach used in WIP overcomes many limitations which would be otherwise difficult to achieve in non-Web service based communication methods used today. WIP is based on two-way, full duplex Web service interaction. The communication signaling establishment in WIP is through Web service interactions, and the media negotiation in WIP is modeled as a special Web service \"event\" subscription, which is fully extensible for various media needs. The signaling messages of WIP are encoded in the standard based SOAP message envelops which can be carried by multiple transport protocols, including HTTP. WIP supports both P2P (peer-to-peer) and B2B (back-to-back) broker mode communication services. A prototype research system has been implemented, and the results indicate that WIP, as a full Web service based communication protocol, is both feasible and advantageous","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128987475","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}

Secure and efficient content delivery has long been a requirement of traditional Web-based distribution schemes, and existing Web infrastructure provides numerous options for securing and optimizing HTTP. Two exemplary technologies are SSL/TLS and HTTP compression. While efforts to solidify the more granular WS-Security standards are ongoing, and methods for XML message compression schemes continue to be investigated, HTTP provides an interim solution, supporting transactional security and message compression. The SSL/TLS and HTTP compression technologies have become commoditized and pervasive. And with the trend in content delivery toward hardware offload for these functions, modern data centers have begun to raise the bar for performance. In this paper, we examine three different paradigms for implementing SSL/TLS and HTTP compression: software-based functionality, server-resident hardware accelerators, and centralized network-resident hardware accelerators. We discuss the trade-offs between the two different offload techniques (i.e., PCI accelerator vs. network proxy) and explore their relationship to the current performance activities, in the field of Web services. In analyzing the results for SSL/TLS offload, and the effects of compression, in conjunction with SSL/TLS, we draw parallels with the efforts of WS-Security and XML message compression. Although optimizations for software-based cryptography continues to advance, the potential for hardware-based acceleration should not be overlooked. We discuss our results and address deployment scenarios for optimizing Web-based transactions, and the future optimization of Web Service transactions","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130991584","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}

Web services standards and protocols aim to support this goal and middleware systems implementing these standards and protocols consequently are needed. Maintenance and administration of middleware is made difficult due to variations in standards and their constant evolution. In this paper, we introduce a new service-oriented middleware architecture for runtime Web services interoperability. Different from other middleware systems our approach applies service-oriented computing principles on the middleware layer, thereby establishing an on-demand model for middleware features. Clients can use middleware as services, dynamically discovering and using the services as interoperability requirements are determined. Further, middleware as services allows middleware to be provided and managed separately from its clients. We present the policy-based programming model, architecture, and details of our middleware, and discuss new challenges that arise in this context, such as distribution of middleware services. The approach is validated through a scenario integrating Web service transaction middleware","PeriodicalId":408032,"journal":{"name":"2006 IEEE International Conference on Web Services (ICWS'06)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115982041","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}

However, in practice, grid resources are not very easy to use for the end-users who have to learn how to generate security credentials, stage inputs and outputs, access grid-based schedulers, and install complex client software. There is an imminent need to provide transparent access to these resources so that the end-users are shielded from the complicated details, and free to concentrate on their domain science. Scientific applications wrapped as Web services alleviate some of these problems by hiding the complexities of the back-end security and computational infrastructure, only exposing a simple SOAP API that can be accessed programmatically by application-specific user interfaces. However, writing the application services that access grid resources can be quite complicated, especially if it has to be replicated for every application.
