Area Directors: Cees de Laat, delaat@science.uva.nl Franco Travostino, travos@nortelnetworks.com Area Scope: The Infrastructure groups explore the interface between grid middleware and lower layer resources. Lower layer resources include networks and network devices, computers, storage, visualization devices, instruments, and sensor technologies. Infrastructure Groups: IPv6 (IPv6-WG) IPv6 is now emerging as a significant factor in operational networks, and continued scaling up of the Internet (and thus of Grids) will require the additional address space and management features of IPv6. It is therefore important that all GGF specifications work as well (or better) with IPv6 as with IPv4. The purpose of the working group is to identify any GGF specifications that do not meet this requirement, to provide appropriate guidelines for future specifications, and to communicate any issues discovered with IPv6 to the IETF, the Java community, etc. Network Measurement (NM-WG) The performance of most grid applications is dependent on the performance of the networks forming the grid. The Network Measurements Working Group (NMWG) identifies network metrics (aka characteristics) useful to grid applications and middleware, and develops standard mechanisms to describe and publish these characteristics to the Grid. Data Transport (DT-RG) The goal of this group is to provide a forum where parties interested in the secure, robust, high speed transport of data in the wide area and related technologies can discuss and coordinate issues, and develop standards to ensure interoperability of implementations. This RG is expected to be a WG "factory" spawning off WGs in areas where sufficient common interest is shown. Grid High-Performance Networking (GHPN-RG) The Grid High-Performance Networking Research Group focuses on the relationship between network research and Grid application and infrastructure development. The objective of GHPN-RG is to bridge the gap between the networking and grid research communities. It accomplishes its goal by serving as a forum for information exchange on advances and requirements in both fields, as well as by providing a focal point for liaison activities between the GGF and the various networking standards bodies. Network Measurements for Applications (NMA-RG) The Network Measurements for Applications Research Group (NMA-RG) will focus on the relationship between network performance characteristics and Grid middleware. The objective of NM-RG is to explore what aspects of the network are most important to Grid middleware, and explore how the knowledge of network behaviour such as bandwidth, latency, or jitter, might be used to build network-aware middleware. |
