• Associated partner: GasLINE, Navtel, Uni Erlangen

• Term of Project: 3 Years – Start of VIOLA: June 2004

– Funding: ca. 11 M € from BMBF (Ministry of Research)

– Total costs: ca. 20 M €




Goals-1

• Test & evaluation of networking technology – L2/L3 VPN Services based on MPLS

• VLL, VPLS, H-VPLS;

• L2 versus L3

• Could be interesting for cooperations within a Service-Provider-Network

– Next Generation SDH

• Provision of efficient Ethernet Services based on SDH,

• P2P-Ethernet-Services, especially within a Service-Provider-Network

– GMPLS/ASON: Signalling mechanisms and interfaces (OIF);

• E2E-Connections, BoD, Interdomain

• International Cooperation

• From Management to Signalling




Goals-2

• Integration of Applications, Middleware – Implement Middleware Environment (UNICORE, Grid, PC-Cluster);

– Implement Middleware Tools:

• Meta-Scheduling

• Network Reservation

– Integrate real users;




Goals-3

• Which Elements will form Hybrid-Networks

(Packet, Circuit)

– What is the user need?

– Still IP, but certain QoS-requirements

– „Hard“ Circuits (Lambda, SDH, ...), „Soft“ Circuits (MPLS VPN)

– Technical platform

– Operational aspects

Equipment (Alcatel-CC 1678) or directly with 10GE-LAN-Phy

– Test: Performance, Functionality

• Current L2-Results

– VLL and VPLS, Basic Functionality, QoS OK

– Interworking Ether Flow Control between L2/SDH-Switches: OK – QoS-Fkt. for b/w limitations (Shaping,Policing;Ingress,Egress): OK

– H-VPLS: Problems, Alcatel/Riverstone not fully compatible

NG-SDH

• Provision of Ethernet-Service over SDH with bandwidthadjustment (NG SDH: GFP, LCAS, VC).

– GFP-F: Generic Framing Procedure, Framed Mode (ITU-T G.7042),

method to transport data packets (e.g. Ethernet) over SDH

– Virtual Concatenation (VC) instead of Continuous Concatenation (CC):

VC4-Container may use different ways in the transport network

– LCAS: Link Capacity Adjustment Scheme (ITU-T G.7041):

dynamical bandwidth adjustment for SDH-links, variable number ofVC4-container within a VC-group during operation



NG-SDH

NG-SDH-Results • Basic tests/interworking between Alcatel-CC-1678,

Siemens-CC-hiT7070 and ADVA-GE-MUX-1500: OK

• LCAS tests between Alcatel-CC-1678 and ADVA-GE-MUX-1500

and test equipment (Acterna, Anritsu): – Working, but ...not all features, difficult to handle

Signalling

Interworking in optical transport networks

– GMPLS for IP-based control plane (IETF)

– ASON / ASTN (Automatic Switched Optical/Transport Network, ITU)

– OIF (Opt. Internetworking Forum): Interfaces based on GMPLS+ASON

– UNI for user controlled signaling

• UNI 1R2: Signalling for SDH-Connections

• UNI 2.0: Signalling for Ether-Connections over SDH

– E-NNI: Interdomain-Interface

– I-NNI: Intradomain-Interface

– OIF-Interfaces include GMPLS-Components like RSVP-TE, OSPF-TE, ...

– Further issues: Peer-/ Overlay-/ Augmented-Model

Middleware

Implementation of a MetaScheduler (based on GGF)• UNICORE Client sends request to MetaScheduler

• MetaScheduler negotiates earliest time to run this job with local schedulers

• MetaScheduler requests the reservation of the requested resources to the

local Schedulers and to the Network Reservation System

Implementation of a Network Reserv. System (ARGON)• Web-Interface is used by the Meta-Scheduler

Initial version of both tools is running in VIOLA




Outlook-1

• Ongoing tests within NG-SDH, H-VPLS and

„Signalling Environment“ (in particular UNI 2.0)

• Upgrade of Equipment (e.g. 40 Gb-components)

• Enhancement of initial version of MetaScheduler

and ARGON (Network Reservation System)



P 23TNC M 2006 P K f /DFN

Outlook-2

• Definition of Commercial Services (e.g. T-Systems)

• Technical Platform and Services in X-WiN

• International Connectivity (NREN), Interdomain

Connectivity

=> Signalling is required, but still to fix

• Architecture: Peer/ Overlay/ Augmented - Model
