Infrastructure Area

The diagram shows the relations and synergy between the various working and research groups within the Infrastructure Area. Please have a look at the thumbnails about the groups given below and remember you are more than welcome to join in the OGF work.

NM-WG The Network Measurements-WG laid the foundations for much of the work on networking that is going on the infrastructure area. It considered in detail the network characteristics that would be relevant to GRID computing, various measurement methodologies and the different types of Observations that could be made. These, together with consideration of the attributes that should be included with the observations resulted in Proposed Recommendation GFD-R.023. Several different versions of XML schemata were developed, implemented and tested by various independent academic groups around the world. This work resulted in the development of the “perfSONAR? network monitoring framework, which currently has over 30 partners – an OGF success story.

NMC-WG Building on the work of NM-WG, this group aims to standardise the XML protocols used to control the network measurements and share the results. They will provide an extensible base schema, specify the extension framework, and provide schemata for the measurement methodologies in current use. As many of the distributed compute environments are inherently multi-domain, these standards are essential to allow effective end-to-end monitoring.

NML-WG The Network Mark-up Language working group aim to define ontology and schemata to allow the description & exchange network topologies in a standardised manner. The goal is to be able to describe multiple network domains and the adaptations or relations between network layers. The working group builds on and combines the work of several initiatives and seeks to incorporate the efforts of other standards bodies such as ITU. The outputs of this working group are directly relevant to network monitoring, NMC-WG, path finding and path provisioning NSI-WG as well as network visualisation and the matching/allocation of GRID application level resources such as databases, high definition displays and input codecs.

NSI_WG The Network Service Interface Working Group was formed after presentation at the GHPN-RG of research work on control plane technology and the realisation that prototype dynamic path provisioning was being piloted by various network providers including GÉANT, SINET, Internet2, SURFnet and ESNET. IN fact, the group is being guided by real-life use cases. They are working on an architecture to enable transactions between a user and a network provider, and between two network operators. They will also specify the protocol and schemata to exchange information about the services (such as topology, path computation, signalling, authorisation, and monitoring) required for dynamic path provisioning. There is interest and support from industry, grid operators and network equipment vendors.

FVGA-WG GRIDs and other distributed computing paradigms have a vision of applications having on-demand, ubiquitous access to distributed services running on diverse, managed resources owned by multiple administrators. Most resources are protected by firewalls, so authorized application need to be able to specify their firewall data-path traversal requirements. The Firewall Virtualization for Grid Applications working group has defined a firewall traversal protocol in a current Draft Recommendation that provides an abstract interface to enable Grid-Middleware and Network services developers to implement a virtualized firewall service and provide dynamic firewall service to the Grid applications

OCCI-WG The Open Grid Forum Open Cloud Computing Interface (OCCI) working group is focused on delivering an API specification for remote management of cloud computing infrastructure, allowing for the development of interoperable tools for common tasks including deployment, autonomic scaling and monitoring. The scope of the initial specification will be all high-level functionality required for the life-cycle management of virtual machines (or workloads) running on virtualization technologies (or containers) supporting service elasticity.

GHPN-RG The Grid High Performance Research Group started by considering how to improve the communication and understanding between the Network community and the emerging GRID community, producing two complementary informational document on “Top ten things network engineers wish grid programmers knew? and “Top ten things grid programmers wish network engineers knew? Another work put together a collections of use cases illustrating the network requirements of different communities of GRID users. In turn it has also focused on innovations in Photonics, The Control Plane and network management systems. It acts as a forum to present and discuss current research work from all over the world and spin off ideas for working groups.
