JRA3 - Bandwidth on Demand:  JRA3 - Bandwidth on Demand GGF16 Athens, 14th February 2006 Afrodite Sevasti GRNET GN2 project:  GN2 project Multi-Gigabit European Academic Network Project funded under FP6 (Research Infrastructures-Integrated Infrastructure Initiative) 31 partners (NRENs, DANTE, TERENA) Total expected budget: 178.643.730 € EC contribution requested: 93.000.000 € Duration: 4 years Combining in a single contract, several activities essential to reinforce research infrastructures and to provide an integrated service at the European level Networking activities (including consortium management) Provision of access to transnational users Joint Research Activities Scope Further develops the successful GN1 project which has created the GEANT pan-European network Specific emphasis on end-to-end provision of services across multiple interconnected networks Gaining improved understanding of user needs Direct support and performance monitoring Migration from IP services to combination of routing and switching, network control, light-paths Goals of JRA3 in GN2 project:  Goals of JRA3 in GN2 project Joint Research Activity aim for a proof-of-concept and pilot network service for dedicated capacity provisioning production service during a subsequent project Streamline the inter-domain setup of ‘lightpaths’ shorten the provisioning time reduce the amount of human intervention Take into account heterogeneity from the beginning Specify and document the manual procedures Automate the process step-by-step focus on inter-domain coordination process Provide northbound interfaces/APIs to applications-middleware Service Definition:  Service Definition Point-to-point, connection oriented service Non-contended capacity Layer 1, 2 focus on provisioning of a deterministic non-contended bandwidth pipe between two 1Gigabit Ethernet access ports over multiple domains that employ different technologies Multi-domain and multi-technology e.g. SDH with GFP, EoMPLS, native Ethernet Automated provisioning Advance reservation (scheduled) Requirements survey:  Requirements survey Deliverable DJ3.2.1: GÉANT2 Bandwidth on Demand (BoD) User and Application Survey disappointing response rate (6 out of 12) GRID community most responsive The questionnaire was organized as follows: General Issues, description of the application Control Issues, requirements on BoD system and its interfaces Network Issues, capacity requirements, service duration, etc. ReIiability Issues, latency, security, restoration, etc. Other Issues, accounting, participation in a BoD pilot, etc. RESULTS: The need for BoD-like services exists today for a (small) number of different communities/projects/users groups BoD users/applications should be provided with “standardized” interfaces for resource reservations and service monitoring: Web services approach looks popular Ability to schedule reservations seems important Bandwidth requirements range from 10 Mbps to 10 Gbps A number of the projects/user groups contacted expressed interest in testing a prototype BoD system State-of-Art survey:  State-of-Art survey Deliverable DJ3.2.2: Initial Review of Technologies Related to the Provision of Bandwidth-on-Demand (BoD) Services Mainly covers: Transmission & switching technologies Control Plane technologies BW broker implementations BMP, CATI, DRAC, DRAGON, ODIN, Operax, SBM, Tequila, UCLP An update is expected during Y2 including: recent developements in the OIF, IETF results of the collaboration with other projects related to JRA3 activities (MUPBED, DRAGON, VIOLA, HOPI ...) Multi-domain provisioning:  Multi-domain provisioning Service characteristics:  Service characteristics Inter-domain: the end user points may be located in different domains Capacity: The minimum amount of capacity that can be requested will depend on local domain policies and restrictions imposed by the technology used (e.g. SDH granularity) Point to point: the BoD service provides Point-to-Point services. Point-to-Multipoint may be realized as a set of point-to-point services Bi-directional: the service is a bi-directional service Symmetric capacity Symmetric paths Advance reservations Protection Inter Domain Manager:  Inter Domain Manager A set of automated procedures for the required non-technology specific inter-domain negotiations in order to establish an end-to-end non-contended 1 GE bandwidth pipe Reservation process Ensure adequate e2e capacity Ensure technical feasibility (e.g. a common VLAN id along the e2e path) Capacity reservation scheduling Path resilience-restoration Intra-domain provisioning:  Intra-domain provisioning Manual intra-domain configurations and provisioning processes for the establishment of the intra-domain segments of the end-to-end path Intra-domain provisioning design to accommodate Domains that have a G.ASON/GMPLS CP “out of the box” e.g. Generic MPLS Routing Engine (distributed control plane in their Alcatel 1678 MCC OXC) Domains operated via NMS Domains that may decide to adopt proprietary Bandwidth Brokers Intra-domain modules, implemented in later phases, will comprise the so-called BoD service Domain Manager (DM) Integration of technologies:  Integration of technologies Evaluating the implementation implications and testing a number or scenarios Monitoring:  Monitoring Inter-domain monitoring system must Troubleshoot in case of failure Provide concatenated monitoring data of the quality of the end-to-end service Working together with relevant GN2 project activities (JRA1 and JRA4) JRA3 will provide technology-specific monitoring data at L1-2 as well as topology data JRA1 will provide monitoring data management and visualization Activities: Design and prototype implementation of the database schema and interface for retrieving and storing monitoring data from the Alcatel NMS (GEANT2 core) Specification and design of the database schema and application for retrieving and storing monitoring data in EoMPLS and native Ethernet topologies Integration of the monitoring data extraction and storage components with the JRA3 Network Topology Database Minimum requirements for monitoring Initially focus on “availability” <= up/down info, unavailable-seconds Also: offered capacity, “errors” <= BER, error counter, errored-seconds Implementation:  Implementation Following the Web-services paradigm Each component of the system is implemented as a Web service Interfaces are defined between IDMs, the IDM and the DM of a domain, the DM and the technology proxy within a domain Using Java, MySQL A prototype of the IDM is expected by May 2006 Liaison activities:  Liaison activities We are looking at: DRAGON (http://cnl.gmu.edu/dragon/) Network Aware Resource Broker (NARB) Virtual Label Switching Router (VLSR) Implementation OSCARS-BRUW projects MUPBED (http://www.ist-mupbed.org), NOBEL (http://www.ist-nobel.org/) VIOLA (http://www.viola-testbed.de/) Testbed ARGON (Allocation and Reservations in Grid-enabled Optical Networks) HOPI- GLIF Working on a Common Service Definition for e2e circuit oriented services with DRAGON/GLIF Joint workshops and meetings
