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-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

VPN
• Operation of L2-Subnetworks – VPLS, H-VPLS (Hierarchical Virtual Private LAN Service)
– Based on Riverstone15008 and Alcatel-7750, connected via SDH-
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

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

Page 22 TNC, May 2006 P.Kaufmann/DFN
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)

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
