Implementations

Here you find a list of WS-Agreement implementations.

GENERIC IMPLEMENTATIONS

WS-Agreement Framework (WSAG4J)

The WS-Agreement Framework provides means to implement WS-Agreement services and the respective client-side access. It is middleware-agnostic, fully compliant with the WS-Agreement Specification version 1.0 and implemented in Java. Currently PendingAgreement and AgreementAcceptance are not supported.

BROKER, SCHEDULER, ETC. IMPLEMENTING WS-AGREEMENT

AgentScape Negotiation Framework

The AgentScape Negotiation Framework is a framework for heterogeneous, mobile agents, which has been realised as part of the AgentScape middleware. It makes use of WS-Agreement to negotiate agreements between agents.

ASKALON GridARM

ASKALON is used to develop and port scientific applications as workflows in the Austrian Grid project. Part of the ASKALON system is GridARM Agreement package that is used to create SLAs Grid resources for a specified time-frame.

AssessGrid Negotiation Manager

The Negotiation Manager is a component of the AssessGrid software stack that implements the WS-Agreement specification as a Globus Toolkit 4.0 service. As the GT4 uses dated versions of WS-Addressing and the WS-ResourceFramework, the namespaces differ from the WS-Agreement Specification version 1.0. Comments and contributions are appreciated. The Negotiation Manager is licensed under the Apache 2.0 license.

BEinGRID Negotiation Manager

The BEinGRID SLA Negotiator component provides a service for negotiating SLAs between a service customer and provider. The protocol used is WS-Agreement (March 2007) and the framework used for WSRF is GT4 ws-core (GT4.0.7). This component's design is based on the BEinGRID Negotiation Common Capability and the BEinGRID Negotiation Design Pattern.

CATNETS

CATNETS realises a Grid market based on an economic self-organization approach of a free market. WS-Agreement is used for the service market and the resource market. CATNETS defines separate bidding languages, which are used by agents to submit bids for services or resources. These languages are mapped onto WS-Agreement via domain-specific schemes.

Job Submission Service

The Job Submission Service (JSS) is a broker aiming at identifying the set of resources that minimizes the Total Time to Delivery (TTD), or part thereof, for each individual job submission. JSS versions with WS-Agreement are currentlz available for Globus Toolkit 4 and NorduGrid/ARC.

VIOLA MetaScheduling Service

The MetaScheduling Service (MSS) is a Grid-level scheduler that has been developed in the German VIOLA project. The MSS is responsible for the co-allocation of resources and the negotiation with the local scheduling systems. It currently uses the UNICORE Grid middleware as a back-end, bute a Globus version is underway. The MSS is distributed under a BSD-like license.

GRID INFRASTRUCTURES IMPLEMENTING WS-AGREEMENT

Akogrimo

In the Akogrimo project the WS-Agreement specification is used to provide a more flexible way to manage e-Contracts in a mobile scenario. The Akogrimo SLA management subsystem is flexible enough to manage the variety of context changes through nternal modules which are in charge of making the infrastructure QoS parameters independent of the particularities of application domains.

SLA TOOLING

ADA

ADA, the Agreement Document Analysis framework, developed by Research Group of Applied Software Engineering composed by research staff of the Dept. Computer Languages and Systems of the University of Seville, is an Agreement Document Analysis Framework which currently support the analysis of WS-Agreement compliant service level agreements.
