Bill Johnston served as ESnet Department Head from Oct. 2003 to Oct. 2008, when he retired. During his tenure Johnston led the effort to develop a new network, ESnet4, to accommodate massive scientific data flows of petabytes/year from the Large Hadron Collider (LHC) at CERN to several ESnet sites for storage and processing and then to multiple universities for analysis. Johnston’s long time research interests included high-speed, wide area network based, distributed systems, widely distributed computational and data "Grids," public-key Infrastructure based security and authorization systems, and use of the global Internet to enable remote access to scientific, analytical, and medical instrumentation. Johnston established the Distributed Systems Department, serving as department head for several years, as well as working as PI for several DOE Office of Science projects related to the application of computing in science environments, as well as several early high-speed network testbeds including the DARPA-funded MAGIC project. Johnston also co-founded the Grid Forum, the precursor to today’s Open Grid Forum. Johnston has worked in the field of computing and its support of the classical sciences for 40 years. He has taught computer science at the under graduate and graduate levels. He has a M.S. in mathematics and physics from San Francisco State University. For more information see www.dsd.lbl.gov/~wej.

In widely distributed systems generally, and in science-oriented Grids in particular, software, CPU time, storage, etc., are treated as “services” – they can be allocated and used with service guarantees that allows them to be integrated into systems that perform complex tasks. Network communication is currently not a service – it is provided, in general, as a “best effort” capability with no guarantees and only statistical predictability.
In order for Grids (and most types of systems with widely distributed components) to be successful in performing the sustained, complex tasks of large-scale science – e.g., the multi-disciplinary simulation of next generation climate modeling and management and analysis of the petabytes of data that will come from the next generation of scientific instrument (which is very soon for the LHC at CERN) – networks must provide communication capability that is service-oriented: That is it must be configurable, schedulable, predictable, and reliable. In order to accomplish this, the research and education network community is undertaking a strategy that involves changes in network architecture to support multiple classes of service; development and deployment of service-oriented communication services, and; monitoring and reporting in a form that is directly useful to the application-oriented system so that it may adapt to communications failures.
In this paper we describe ESnet's approach to each of these – an approach that is part of an international community effort to have intra-distributed system communication be based on a service-oriented capability.
