CAON contributions at FSAN are being centralized by Thomas Pfeiffer (ALU)

Key issuesOFDM based NGPON2 solutions are still in an early stage for

standardization Still, in terms of expected total system costs it cannot compete with

conventional TDM/WDM-based PON solutions taking into account the current state of component technologies

A solid recommendation to FSAN to choose OFDM technology for NGPON2 solutions can not be done yet

PCEP Extensions for GMPLS. This provides extensions for the Path Computation Element communication Protocol (PCEP) for the support of GMPLS control plane. Contributions were brought to the IETF draft draft-ietf-pce-gmpls-pcep-extensions-03

The target of the contribution was draft-zhao-pce-pcep-inter-domain-p2mp-procedures-07

PCEP Extension for WSON Routing and Wavelength Assignment . This contribution extends the PCEP protocol for flexible Routing and Wavelength Assignment in Wavelength Switched Optical Networks. Current working draft is draft-lee-pce-wson-rwa-ext-02.tx

Extensions to Path Computation Element Communication Protocol (PCEP) for Hierarchical Path Computation Elements (PCE). This document defines the Path Computation Element Protocol (PCEP) extensions for the purpose of implementing hierarchical PCE procedures which are described in [PCE-HIERARCHY-FWK]. Relevant draft draft-zhang-pce-hierarchy-extensions-00

Methods and extensions / standard way to represent domain sequences in various deployment scenarios, including P2P, P2MP and HPCE, involved draft: draft-dhody-pce-pcep-domain-sequence-01

Some of these contributions are still at early stages, potentially being merged, replaced, etc. Also, note that the PCE WG re-chartered a few weeks ago, so it is expected that some of the individual drafts will be proposed / adopted as working group items (e.g. the poll for adoption of draft-zhao-pce-pcep-inter-domain-p2mp-procedures-06 closed recently)

Finally, testing in the scope of WP3 and WP4 identified problems regarding PCEP transport (TCP ports) which have been addressed as erratas to RFC5440 (main PCEP RFC) regarding, notably port restrictions

.

STRONGEST standardization interests in IETF in details


Project name: STRONGESTMain topics of interest on standardization: resource and

admission control, energy efficiencyTargeted standardization fora: ETSIStandardization status:

• A first contact with ETSI TISPAN has been made, and it is intended to present STRONGEST there in the next year. Once a suitable RACS extension has been defined within STRONGEST, it is planned to contribute it to TISPAN.

• A first presentation of the STRONGEST project and its goals has been made to ETSI EE, and a liaison exchange has been started in order to gain access to latest ETSI work and to inform EE about positions and developments at STRONGEST. It is expected that STRONGEST extensions to the metric will be contributed to ETSI EE once the work has sufficiently progressed.

Standardization in SARDANA

SARDANA project targets a practical transparent approach to Access&Metro Convergence.

Presence and contribution to FSAN mainly:

• Optically converged Hybrid Ring-Tree WDM-TDM Metro-Access Architecture

› Passive Ring-Tree Interface (Remote Node)• Multi-operability, scalability and transparency.

List of FSAN meeting attended :• Japan – Kyoto, Lake Biwako November 2009• USA – San Francisco February 2010• China – Beijing April 2010• Europe - Munich - September 2010• USA – Las Vegas – November 2010• Japan – Tokyo – January 2011

Three persons of SARDANA project were participating at FSAN meetings, from FT-Orange, IT and ISCOM.


Standardization activities• Poster about SARDANA during 2009 Kyoto meeting

(and to ECOC’09)• a presentation on "Interest in NGPON2 at FT" with the

Sardana solution, (Kyoto)• Call For Contribution on extended reach and topics for

NG-PON2 workshop as Wavelength Stacking, Central Office Consolidation, Achievable Optical Budget

projections.• White Paper on the drivers, requirements, and

technologic evolutions for NG-PON2 : introducing the concept of SARDANA ring-tree solutions.

• Several publications in Sardana (ECOC'09, ICTON’10) describe and specify key Sardana elements (like the ring-tree Remote Node) in terms

of Standardization, as proposals for NGPON2.

• In every Sardana plenary meeting, the FT, IT and ISCOM partners, that attended these Standardization meetings, updated the Sardana partner

representatives (with the required confidentiality) with the latest recommendations, so the designs have been aligned at every time as

much as possible.

Access:•Key parts of the WDM 10G TDM PON were presented to FSAN/ITU.•By closely following the work in the XMD MSA (10 Gbit/s miniature device multi-source agreement), 3S Photonics succeeded in being the first company to implement a SFF TOSA (Small Form Factor Transmitter Optical Sub Assembly) module according to this standard. •Acreo’s work on GMPLS in a unified control plane for an integrated access/distribution network was based on existing standards, and specific extensions (to include various flavours of Ethernet into the GMPLS framework) have been proposed. The target body is IETF. Home:•A specification for POF home networking (ETSI TS 105 175): Contribution to basic document and amendments (and a proposal for further actions (as described in this Deliverable) •Passive structured cabling infrastructure (EN 50173 and ISO/IEC 11018) via DKE-715 working group with active contribution regarding home network architecture, experience from field trials and proposing extensions and amendments.•POF connectors (ISO/IEC 61754) by contributions with results from measurements and field trials (Telekomunikacja Polska, Telefonica I+D, Homefibre)•Gigabit Ethernet Standardisation DKE 412-3 working group with contribution regarding home network architecture, technical concepts and system requirements as well as technical solutions, testing results and measurements-
