“…The existence of multiple entry points may be dictated by security policies (the presence of multiple security zones), robustness (fault tolerance), or performance requirements (load is balanced on a cluster of SON appliances). SON appliances can implement a number of functions, which include functional offloading, service integration, and intelligent routing [14]. In addition to providing these functions, SON appliances are also responsible for controlling the rate at which client requests are sent to the service hosts.…”

International audienceIn recent years, Service Oriented Architectures (SOA) have emerged as the main solution for the integration of legacy systems with new technologies in the enterprise world. A service is usually governed by a client service contract (CSC) that specifies, among other requirements, the rate at which a service should be accessed, and limits it to no more than a number of service requests during an observation period. Several approaches, using both static and dynamic, credit-based strategies, have been developed in order to enforce the rate specified in the CSC. Existing approaches have problems related to starvation, approximations used in calculations, and rapid credit consumption under certain conditions. In this paper, we propose and validate DoWSS, a doubly-weighted algorithm for service traffic shaping. We show via simulation that DoWSS possesses several advantages: it eliminates the approximation issues, prevents starvation and contains the rapid credit consumption issue in existing credit-based approaches

In Enterprise Data Centers (EDC), service providers are usually governed by Client Service Contracts (CSC) that specify, among other requirements, the rate at which a service should be accessed. The contract limits the rate to no more than a number of service requests during a given observation period. In two-tier setups, a cluster of Service-Oriented Networking (SON) Appliances form a pre-processing tier that accesses services in the service tier. SON Appliances locally shape the flow of requests to enforce the global rate defined in the CSC. Off-the-shelf SON Appliances present architectural limitations that prevent them from being used to efficiently perform traffic shaping in the presence of multiple service hosts. In this paper, besides identifying these limitations, we provide two contributions in this field. First, we introduce a SON Appliance architecture fit for multi-service traffic shaping. Second, we propose and validate an algorithm for multipoint-to-multipoint service traffic shaping in two-tier EDCs. We show via simulation that our approach solves the multipoint-to-multipoint service traffic shaping problem while pushing the system to its maximum capacity.

“…A consequence of the constraint is that SOA applications almost always have to be operated in a distributed environment ( [7], [8]). Consequently, the endusers and service providers are geographically distributed.…”

Various security and privacy issues have emerged from the SOA healthcare platform. Large amounts of personal data are transmitted daily through the SOA healthcare platform. For security and privacy reasons, the exchanged data should be encapsulated and encoded by a specific standard, a customized standard even. In this study, we first focused on investigating the importance of data exchange and message passing on SOA from the security and privacy viewpoints. Thereafter, we designed a gateway for passing message in the SOA healthcare platform. Subsequently, we initially pointed out the interface utilities on the SOA healthcare platform. Health data format and health packet format were then defined. Finally, the transmission mechanism between the sender and the receiver was exposed. As the practical results in beta-test, the messages could be passed in a secure and reliable routing. These customized messages were able to successfully avoid recognition when they were intercepted by the other P2P streaming tools.
