Key issues
OFDM
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

•
communication Protocol (PCEP) for the support of GMPLS control plane. Contributions
were brought to the IETF draft draft-ietf-pce-gmpls-pcep-extensions-01
PCEP Extensions for Temporary Reservation. The contribution proposes an extension to
the PCEP protocol to allow the PCC to request the PCE to block or reserve the resources
computed in a path request of a TE LSP for subsequent requests for a certain time. The
relevant draft is draft-gonzalezdedios-pce-resv-res-context-state-00
PCE Extensions for Multi-Domain P2MP Path Computation. The contribution describes the
procedures and extensions to the PCE communication Protocol (PCEP) to handle requests

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 ETSI

admission control, energy efficiency

Standardization status:

•
ETSI
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 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.

•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.
