Agents and Peer-to-Peer Computing: First International by Gianluca Moro, Aris M. Ouksel, Claudio Sartori (auth.),

By Gianluca Moro, Aris M. Ouksel, Claudio Sartori (auth.), Gianluca Moro, Manolis Koubarakis (eds.)

Peer-to-peer (P2P) computing is at the moment attracting huge, immense public realization, spurred through the recognition of file-sharing structures resembling Napster, Gnutella, and Morpheus. In P2P structures a truly huge variety of independent computing nodes, the friends, depend upon one another for companies. P2P networks are rising as a brand new disbursed computing paradigm as a result of their capability to harness the computing strength of the hosts composing the community, and since they make their underutilized assets on hand to every other.

This e-book brings jointly 3 specially commissioned invited articles, an advent, and revised types of the papers offered on the 1st overseas Workshop on brokers and Peer-to-Peer Computing, AP2PC 2002, held in Bologna, Italy in July 2002. The ebook is prepared into topical sections on peer-to-peer companies, discovery and supply of reliable providers, and seek and cooperation in peer-to-peer agent systems.

Example text

Discovery is via cooperative lookup; endorsement is through community and rational interaction; and monitoring and compliance is through checking by the community. There are two main claims here. One, without agent-based referrals, P2P systems will remain inadequate for addressing the challenges of information systems: requiring manual configuration (leaving much complexity for application designers) or being inherently limited to the low-level infrastructure. Two, equipped with referrals, P2P systems can address many of the challenges facing information systems.

To achieve this, programmers must specify the kind of action their peers invoke and also the kind of action their peers provide. In our opinion, it is most important to qualify a service Peer Services: From Description to Invocation 23 and be sure of the task it will perform rather than simply reference its name without any assurance on its behaviour as it is the case with approaches like CORBA, DCOM or RMI. Asynchronous Communications. All invocations will be one-way. This means that calling peers do not wait for an answer.

The methods of roles are merely declared as normal methods. 6 Peer-to-Peer Services with VPC VPC makes information agents act as roles in a policy package. Authorized users that have certificates can see and use the information through assigned roles. In addition, VPC supports location dependent services; Fig. 4 shows the overview of location dependent services. In VPC, location dependent services are also described as policy packages. The policy packages contain roles for browsing a list of services that are provided at the location, and for downloading the policy packages.
