This paper gives an overview of the issues related to the QoS mechanisms under IPv6 and the transition of applications to the new Internet protocol. We describe the implementation and testing of a QoS service on IPv6 networks, which is based on the DiffServ architecture (expedited forwarding) and provides strict priorities to packets that are produced from real time applications. The service wa...

Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard. Distribution of this memo is unlimited. Discussion As a result of the NREN NIS award by National Science Foundation, non-DDN registration services will soon be transferred from the DDN NIC to the new Internet Registration Service, which is a part of an entity referred to as t...

Transition to IPv6 has been recognized as the trend of future Internet. Since a huge amount of resources have been invested on current IPv4-based Internet, how to smoothly transit the Internet from IPv4 to IPv6 is a very important research topic. This paper surveys the state of the art in IPv6 transition, summarizes and compares different IPv6 transition mechanisms and scenarios, discusses the ...

Outsourcing information system development has become a common practice in companies. Many contributions were proposed for dealing with the management of such projects, and relationship between client and vendor. But little is known concerning the way to manage the change of service provider in an on-going project. Our study concerns the transition from an outgoing service provider to an incomi...

OBJECTIVE This study aims to conduct qualitative research on the perspectives of service providers regarding the transition process from pediatric to adult specialized eating disorder tertiary care programs. METHOD Two focus groups with a diverse group of clinicians in pediatric and adult eating disorder programs and five qualitative interviews with clinicians in the community were conducted....

In this paper we study the issue of service composition, for services that export a representation of their behavior in the form of a finite deterministic transition system. In particular, given a specification of the target service requested by the client as a finite deterministic transition system, the problem we face is how we can exploit the computations of the available services for realiz...
