MUPBED Goals and Objectives

integrate and validate “telecommunication operator’s concepts” within research networking infrastructure

on-demand circuit switching techniquesin particular ASON/GMPLS control plane technologies

consider a multi-domain, multi-layer “real world” environmentidentify service/network requirements of high-end applications for European research environments and develop appropriate solutionscreate a European scale experimental environment to assess and prove the developed solutionsdevelop guidelines for the introduction of ASON/GMPLS technologies and ultra-broadband services in future European networks (including research networks)

(note: here the term “ASON” covers multiple transport technologies, such as WDM, OTH, SDHalso frequently used is the term “ASTN” in this context; acronyms: see last slide)

Relevance of MUPBED for NRENs

convergence of “telecom operator” and NREN solutionsnetwork architecture work, selected theoretical investigationsleading edge control plane solutions:

focus on ASON approach, including multi-domain inter-working driving standardisation

work on “application – network” inter-working (details: see back-up):dedicated MUPBED Work Package (WP 2)applications (requirements, selected trials in test bed)user groups (within and outside the MUPBED consortium)modelling and simulationsapplication network interface (translation of requirements to network parameters, triggering of resource allocations, …)

extended field trials for selected solutions: set-up and operation of European scale test bed

Test Bed Interconnection – Approach

MUPBED follows a step-wise approach:initial step: connectivity on IP layercurrent step: full mesh of test beds on layer 2 (Ethernet VLANs)

achieved by LSPs within NRENs and DANTE networksthis step required the solution of technical and political issues

last mile interconnection between test beds and NREN PoPslegal issues for using fibres for such a “permanent, non-commercial” activitylegal issues for accessing NRENs from “private bodies”technical issues for LSP stitching, VLAN realisation

future step: selected interconnections on layer 1realistic technology: SDH VC-4 interconnectionpotentially only between selected test beds and/or temporarily

Original WP2 objectives

To define for the MUPBED applications how the resource requests are translated to network understandable QoS parameters.To define the required level of dynamics of the resource allocation with respect to performance, stability and other network administrative issues.To determine the scalability of the MUPBED concept for differentapplication groupsTo verify the advantages and drawbacks of a dynamic infrastructure To strengthen and enhance the contact and collaboration with user communities.To increase a common understanding from user groups, through NREN to service providers of what layer is responsible for what.

MUPBED Test Bed Inter-domain interfaces: Current implementations

MUPBED is based on five different test bed domains, which will be integrated to a European scale test bed To realize interworking functions among these local test beds,inter-domain signaling/routing interfaces are strongly neededFirst inter-test bed / inter-domain interface implementation:

Virtual E-NNI between Torino/TILAB – Berlin/DTNext step: Real UNI2.0 Ethernet implementation

UNI-C 2.0 Ethernet interface availability:easy availability and access of this UNI-C function is mandatory for accelerating the deployment of customer controlled Ethernet services over SDH networksrequirements for broad acceptance:

(publicly) available and easy to implement easy to use for those envisaged (network) clients, for which thecomplexity of network operation shall be hidden

Interworking IP/MPLS – GMPLSBasic questions:

is a common framework / protocol set reasonable for completely different technologies (“optical circuits” and “electronic packets”) for core/metro networks?

overall optimisation versus sub-optimal solution for each areamight be much more complex than two different solutionsconsider also the different “time domains” in the different layers

do all operators want to combine these “worlds”?operational / structural / technical reasons for “separate worlds”

Other issues:new features of GMPLS (compared to MPLS), such as:bi-directional LSPs, label suggestion, label restriction, graceful restart, gracefulteardown, forwarding adjacenciesdifferences between MPLS and GMPLS for several features:local protection, routing, signallingGMPLS has separation of data and control plane, MPLS does not

Potential solution(s):UNI or a kind of E-NNI between the layersMPLS could also learn some things from GMPLS (e.g. bi-directional paths)

10/11/2005 - 79

Management AspectsMPLS has a management plane – driven by operator actions, as well as a control plane – driven by signalling

Still relatively immature, e.g. in terms of planning tools and OAM featuresEasier therefore to deploy MPLS in core networks rather than edge, where scalability and feature richness become issues

GMPLS management plane is likely to stay separate for a while –operators demand high stability in their optical backbone

Optical Transport Network (OTN) emerging for carrier’s carrier and other payload-independent transport applications

Today carry up to 10 Gbit/s in SDH or Ethernet formatMonitor digital quality of wavelengths at handover between operators

Increasingly integrated with SDH at both hardware and managementlevels
