Grid High Performance Networking (GHPN) Research Group

Franco Travostino, Constantinos A. Kotsokalis
(GHPN-RG) Group Discussion
View Participants
We have added this GHPN session to hear about European efforts in Research & Experimental networks for Grids, and foster the dialogue with other initiatives around the world. Do the various efforts agree on a roadmap for standardization of Grid Network Services?
Agenda:
Prof. Dimitra Simeonidou: Lambda User Controlled Infrastructure For European Research (LUCIFER)
LUCIFER addresses some of the key technical challenges to enable on-demand e2e network services across multiple domains. The LUCIFER network concept and test-bed will make applications aware of their complete Grid resources (computational and networking) environment and capabilities, and able to make dynamic, adaptive and optimized use of heterogeneous network infrastructures connecting various high-end resources.
The LUCIFER testbed will interconnect European and Worldwide experimental facilities over optical infrastructures. Specifically, the test-bed will involve European NRENs and national test-beds, as well as GÈANT2, Cross Border Dark Fibre and GLIF infrastructures. A set of highly demanding applications will be adapted to prove the concept.
Dr. Peter Kaufmann: The VIOLA project
The German optical testbed VIOLA has been started in summer 2004 in the region of North-Rhine-Westphalia with an extension to Bavaria. It is an integrated testbed for applications and advanced network services, organised as a consortium with partners from industry, research laboratories, universities and the DFN association. Major goals are the test of different signalling mechanisms in a heterogeneous environment of routers and switches and the development of a user-driven dynamical bandwidth allocation. The talk will be focussed on the results of tests, examinations and implementations in the area of network technology, such as:
· Provision of Layer 2 Services (VPLS, H-VPLS, VLL);
· Interworking in optical transport networks (GMPLS, UNI, I-NNI, E-NNI);
· Implementation of an end-to-end signalization;
· General functionality tests of the ”new SDH” features (Virtual Concatenation (VC), Link Capacity Adjustment Scheme (LCAS), Generic Framing Procedure (GFP).
Afrodite Sevasti: The GN2 JRA3
The JRA3 Activity of the GN2 project is about the investigation and development of an end-to-end (and therefore multi-domain) “Bandwidth Allocation and Reservation Service” – in other words a “Bandwidth on Demand” (BoD) service over multiple interconnected network domains. The proposed service model aims to fulfil the needs of several projects and research infrastructures involving high bandwidth connections among distributed sites. The ultimate goal is to provide “circuit-based” bandwidth provisioning between end-users or sites in a way that the bandwidth is reserved, not contended, exhibits some form of deterministic performance and is logically separated from other traffic sharing the network. The work carried out focuses initially on defining and implementing an architecture for coordinated provisioning of bandwidth pipes, including path discovery, AAI functionality, advance reservations and monitoring, by hiding the technology-specific implications of stitching different technologies used along the end-to-end path and providing the service to the requesting user in an on-demand fashion.
Tomohiro Kudoh: The G-Lambda project
G-lambda project has been started in December 2004. The goal of this project is to establish a standard web services interface (GNS-WSI) between Grid resource manager and network resource manager provided by network operators.
We have defined a preliminary interface, and conducted a experiment using a JGN II GMPLS-based network test bed. In the experiment, a user requests an environment by specifying the required number of computers and the network bandwidth. The computing resources and GMPLS network resources are reserved as the result of interworking between the Grid resource scheduler and network resource management system using GNS-WSI,
and a simulation is executed using the reserved resources.
In the future, we will focus on detailed specifications of the GNS-WSI, and are aiming to make this technology both open, and a global standard.
Sergi Figuerola: User Controlled Light Paths (UCLP)
The User Controlled LightPath (UCLP) software will enable users to define their own packet or switched based network architecture including topology, routing, virtual routers, switches virtual machines and protocols based on the concept of many separate and independently managed Articulated Private Networks (APN) operating on top of one or more network substrates across different ownership domains. APNs can be considered as a next generation Virtual Private Network where user can create a complex network structure, in any way they wish, by binding together layer 1 through 3 network links, instruments, computers, time slices and virtual or real routing and/or switching nodes. This capability is enabled through UCLP by representing all such network element, devices and links as web services, and by using web services workflow as the tool to allow the user to bind together their various web services to create a long lived APN instantiation. With web services workflow the user also has the ability to offer all, or portions of their APN as a web service (or set of services) in is own right to other downstream users.
